From 3b2b4a1fdd682844c5830becdb57739443ee1f70 Mon Sep 17 00:00:00 2001 From: Chris Burns <29541485+ChrisJBurns@users.noreply.github.com> Date: Tue, 21 Apr 2026 20:52:50 +0100 Subject: [PATCH 001/291] Compare CRDs against the last release tag, not the rendered chart (#4987) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The advisory workflow added in #4980 rendered both the last-published OCI chart and the PR tree through helm template, filtered the result through yq, and fed the concatenated output to crd-schema-checker. Two problems: 1. crd-schema-checker reads only the first document of a multi-doc YAML file, so 11 of 12 CRDs were silently skipped. Breaking changes to anything alphabetically after embeddingservers passed the check with no findings. 2. The whole render pipeline was needless machinery. files/crds/ is the controller-gen source of truth, committed to git, and each file already contains exactly one CRD. Rendering the Helm chart only added Helm conditionals and a keep annotation, neither of which the checker inspects. Replace the resolve-source → helm pull → helm template → yq split → checker chain with: fetch the last release tag, iterate over each file in files/crds/, and run the checker once per pair, diffing the current file against git show "$TAG:". This also catches CRD removal via simple filename set difference. Drops: - azure/setup-helm entirely - helm pull from OCI and the release-publish-window concerns - helm template ×2 and the --set-flags insulation - yq and the multi-doc filter - The per-CRD yq split workaround for the checker's multi-doc bug Verified locally: - HEAD vs v0.23.0 untouched: exit 0, no findings. - Simulated mcpgroups description→summary rename: exit 1, two NoFieldRemoval findings (v1alpha1 and v1beta1). Before this change the same scenario reported "Compatible" because mcpgroups was one of the 11 silently-skipped CRDs. Follows up on #4980.

Three pieces: 1. Workflow: drop continue-on-error, add an if: guard on the job that skips the check when the api-break-allowed label is applied. A skipped required-check counts as passing for branch protection, so the label is the only path through for an intentional break. Update the header comment and step summary heading to drop the "Phase 1: advisory" framing. 2. CONTRIBUTING.md: add a new "API Stability" top-level section with the v1beta1 stability contract (no field removal, type change, new required fields, validation narrowing, finalizer rename, spec.scope flip, un-serving a served version). Separate subsection documents the api-break-allowed escape hatch and the maintainer-coordination expectations. 3. PR template: add an "API Compatibility" section after Test plan that prompts contributors to describe the break + migration path when the label is applied. Section is standing (GitHub templates don't support conditional rendering) but the wording makes the N/A-for-non-breaking-PRs case explicit via the checkbox. Post-merge maintainer actions (not code, can't be automated from a PR): create the api-break-allowed GitHub label, and add "CRD Schema Compatibility" to the required status checks in branch protection for main.

This avoids invalid container-name characters (e.g., slashes in `BAAI/bge-small-en-v1.5`). + +**Ownership tracking**: `EmbeddingServiceManager` sets an internal `started` flag only when it deploys the container itself (`deployContainer`). When it finds an already-running container and calls `reuseContainer`, `started` remains false. + +**Reuse semantics**: if a container with the correct name is already running when `thv vmcp serve` starts (e.g. left running by another process or a previous invocation that did not shut down cleanly), ToolHive reuses it and does not stop it on exit. In the normal case — where `thv vmcp serve` itself deployed the container — it will stop it on shutdown, so the next invocation will redeploy from scratch. + +**Health polling**: exponential backoff starting at 2 s, multiplier 2, cap at 30 s per interval. `pollHealth()` polls until the passed `context.Context` is cancelled — there is no built-in total-time budget. `thv vmcp serve` passes `cmd.Context()` without an additional deadline, so polling continues indefinitely until the user cancels (Ctrl-C) or the context is otherwise closed. + +**Graceful shutdown**: `EmbeddingServiceManager.Stop()` stops the TEI container only if this instance deployed it (`started == true`). It is a no-op when the container was reused from an external process. + +**Implementation**: `pkg/vmcp/cli/embedding_manager.go` + +#### ARM64 / Apple Silicon Note + +The default TEI image (`ghcr.io/huggingface/text-embeddings-inference:cpu-latest`) is published as an `amd64`-only image.

The controller writes finalizers, finalizer removal, and the restart-processed annotation via r.Update. Update is a full PUT, so any spec field the operator does not track — most importantly spec.authzConfig, which a separate authorization controller will soon own — is zeroed on every reconcile. Replace the three Update call sites with an optimistic-lock merge patch. The merge-patch body carries only fields the caller changed, so untouched fields never hit the wire and cannot be clobbered. MergeFromWithOptimisticLock sends resourceVersion as a precondition, giving 409-on-collision semantics for concurrent writers and defending metadata.finalizers (which has no array-merge semantics under merge-patch) against wholesale replacement when another controller is mid-flight adding its own entry. Tests: - Envtest suite writes spec.authzConfig out-of-band and asserts it survives both the finalizer-add reconcile and the restart-annotation reconcile. - Unit suite uses a patch-recording client to assert each migrated call site emits a body carrying the resourceVersion precondition — a deterministic wire-level signal that MergeFromWithOptimisticLock is in effect. A regression to plain MergeFrom would drop the precondition and fail the assertion independent of the higher-level survival test. Also: - .claude/rules/operator.md: new "Spec / metadata patching" section documenting the pattern for future CR writes. Status patching is a separate follow-up (#4633). - Rename the mock-client flag failOnMCPServerUpdate → failOnMCPServerWrite; it now intercepts both Update and Patch on MCPServer, so the name matches reality. --- .claude/rules/operator.md | 40 ++++ .../mcpexternalauthconfig_controller.go | 10 +- .../controllers/mcpserver_controller.go | 40 ++-- .../controllers/mcpserver_restart_test.go | 37 +++- .../controllers/mcpserver_spec_patch_test.go | 184 ++++++++++++++++++ .../controllers/toolconfig_controller.go | 10 +- .../mcpserver_spec_patch_integration_test.go | 168 ++++++++++++++++ 7 files changed, 464 insertions(+), 25 deletions(-) create mode 100644 cmd/thv-operator/controllers/mcpserver_spec_patch_test.go create mode 100644 cmd/thv-operator/test-integration/mcp-server/mcpserver_spec_patch_integration_test.go diff --git a/.claude/rules/operator.md b/.claude/rules/operator.md index a8afc8cc29..1baae52975 100644 --- a/.claude/rules/operator.md +++ b/.claude/rules/operator.md @@ -67,3 +67,43 @@ task operator-test # Run unit tests task operator-e2e-test # Run e2e tests task crdref-gen # Generate CRD API docs (run from cmd/thv-operator/) ``` + +## Spec / metadata patching + +Never use `r.Update` on a CR spec or metadata: `Update` is a full PUT, +so any field our local copy does not track (e.g. `spec.authzConfig` +written by a separate authorization controller) gets zeroed on every +reconcile. + +Use an **optimistic-lock merge patch** instead.

This also meant slog.Debug calls in dependent packages (e.g. Cedar's "Resolved JWT claim keys for Cedar evaluation" log at pkg/authz/authorizers/cedar/core.go:452) were never visible even with --debug on the command line.

Cedar evaluated against the ToolHive-issued AS token rather than the upstream IDP token, and the claim was missing. Derive the field from Spec.AuthServerConfig.UpstreamProviders[0].Name in convertIncomingAuth when an embedded auth server with upstream providers is configured. Mirrors injectSubjectProviderIfNeeded in virtualmcpserver_controller.go (outgoing auth) and injectUpstreamProviderIfNeeded in pkg/runner/middleware.go (thv run path). Leaves the field empty when no embedded AS or no upstreams so Cedar correctly falls back to ToolHive-issued claims in those modes. Fixes #4997 * Reject VirtualMCPServer authz without an upstream IDP When IncomingAuth.AuthzConfig is set but no upstream IDP is configured, Cedar silently evaluates policies against the ToolHive-issued AS token. That token's claim namespace (sub, aud, tsid) can overlap upstream claims and authorize against the wrong identity, so the misconfig must be surfaced rather than deployed. Add validateAuthzUpstreamAvailable to the VirtualMCPServer reconciler chain. When AuthzConfig is set but AuthServerConfig is nil or UpstreamProviders is empty, mark the server Failed and set AuthServerConfigValidated=False with reason AuthzRequiresUpstream. The user-facing message points at spec.authServerConfig.upstreamProviders, which is where the fix belongs. Extract runAuthValidations from runValidations so the auth-related checks live together and gocyclo stays happy. No behavior change in the moved block. Belt-and-suspenders companion to the converter fix in the previous commit: the converter wires the provider name when upstreams exist; this validator makes the absence of upstreams an explicit failure. Refs #4997 * Verify Cedar reads upstream claims via PrimaryUpstreamProvider Behavioral regression guard for the converter fix in the preceding commit. With the same identity, upstream token, and Cedar policy, flip PrimaryUpstreamProvider between "okta" and "" and observe the outcome change from permit to deny through the real middleware stack. This pins the runtime contract below the operator-layer fix: when the converter populates PrimaryUpstreamProvider, Cedar resolves principal.claim_* from the upstream IDP token; when it is empty, Cedar falls back to the AS-issued token's claims (which do not carry upstream profile attributes). Uses has-attribute rather than equality so a failure uniquely signals "the claim source Cedar read from lacked this attribute" — the exact #4997 regression shape. Refs #4997 * Address review feedback on #5002 Key change: narrow validateAuthzUpstreamAvailable to only reject when an embedded auth server is configured but has no upstream providers. Previously the validator rejected any authz configuration without an embedded auth server, which false-positived direct-IdP deployments where the client presents an Okta/Entra/etc token directly and Cedar evaluates against identity.Claims via the default branch. Thanks to Trey for catching this regression during review. Additional review feedback addressed: - Advisory status condition AuthzUpstreamSelectionWarning surfaces which upstream was auto-selected when multiple are configured (F2). Condition is set only on the applicable path; stale conditions are removed via RemoveConditionsWithPrefix on non-applicable paths so normal VMCPs do not carry a False/NotApplicable advisory row. - Use errors.New instead of fmt.Errorf("%s", msg) (F3). - Emit a WARN-equivalent log (logr.Info at V=0, matching the file idiom) when rejecting so operators have a grep-able signal (F5). - Update runValidations doc comment after the earlier runAuthValidations extraction (F7). - Assert UpdateStatus bool return in error-path test subtests (F9). - Add double-nil (AuthServerConfig nil and AuthzConfig nil) converter subtest (F12). - Switch new tests to t.Context() (F14).

Expose RequestedTokenType and Resource fields on tokenexchange ExchangeConfig so callers can request non-default token types (RFC 8693) and specify an RFC 8707 resource indicator. Additional URN constants (JWT-Bearer grant, ID-JAG token type) will be added by the PRs that introduce their first consumers. Enforce RFC 8707 Section 2 constraints on Resource in ExchangeConfig.Validate(): reject non-absolute URIs and URIs with a fragment component. The godoc already stated the contract; this makes Validate() fail loudly at config time rather than forwarding a bad resource indicator to the STS. Regenerate docs/server/ to pick up the updated SubjectTokenType godoc wording in tokenexchange.Config. --- docs/server/docs.go | 2 +- docs/server/swagger.json | 2 +- docs/server/swagger.yaml | 4 +- pkg/auth/tokenexchange/exchange.go | 77 ++++++---- pkg/auth/tokenexchange/exchange_test.go | 179 ++++++++++++++++++++++-- pkg/auth/tokenexchange/middleware.go | 21 +-- pkg/oauth/constants.go | 22 +++ 7 files changed, 249 insertions(+), 58 deletions(-) diff --git a/docs/server/docs.go b/docs/server/docs.go index 27f4c5ae10..4f469fc5ab 100644 --- a/docs/server/docs.go +++ b/docs/server/docs.go @@ -379,7 +379,7 @@ const docTemplate = `{ "uniqueItems": false }, "subject_token_type": { -

JWT/OIDC incoming auth: starts an in-process OIDCMockServer, configures vMCP with incomingAuth.type=oidc, verifies unauthenticated MCP clients are rejected, then confirms a client_credentials JWT allows connection and tool listing. - Redis session storage: starts a redis:7-alpine Docker container as a fixture, configures vmcpconfig.SessionStorageConfig with provider=redis, and confirms vMCP starts (Redis Ping on startup) and MCP connectivity works end-to-end. Adds two helpers to mcp_client_helpers.go: - NewMCPClientForStreamableHTTPWithToken: passes a Bearer token on every request - WaitForVMCPHealthReady: polls /health endpoint (needed when OIDC blocks unauthenticated MCP probes used by WaitForMCPServerReady) Closes: #4944 Co-authored-by: taskbot --- test/e2e/mcp_client_helpers.go | 47 +++++ test/e2e/oidc_mock.go | 114 +++++++++--- test/e2e/vmcp_cli_helpers_test.go | 6 + test/e2e/vmcp_infra_features_test.go | 257 +++++++++++++++++++++++++++ test/e2e/vmcp_optimizer_test.go | 6 - 5 files changed, 402 insertions(+), 28 deletions(-) create mode 100644 test/e2e/vmcp_infra_features_test.go diff --git a/test/e2e/mcp_client_helpers.go b/test/e2e/mcp_client_helpers.go index a78c4dd765..bf132369bc 100644 --- a/test/e2e/mcp_client_helpers.go +++ b/test/e2e/mcp_client_helpers.go @@ -6,10 +6,13 @@ package e2e import ( "context" "fmt" + "io" + "net/http" "strings" "time" "github.com/mark3labs/mcp-go/client" + "github.com/mark3labs/mcp-go/client/transport" "github.com/mark3labs/mcp-go/mcp" .

72ef8359bb97062e671e88ef4424cf2922b1c06e Mon Sep 17 00:00:00 2001 From: Samuele V <4377202+samuv@users.noreply.github.com> Date: Thu, 23 Apr 2026 10:53:40 +0200 Subject: [PATCH 019/291] Classify OCI pull errors and fall back to git for skills content API (#5014) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Surface upstream error messages for 502/503/504 in API handler Today every 5xx response body collapses to http.StatusText(code), which is appropriate for 500 (may wrap DB drivers, container runtimes, connection strings) but hides actionable detail for 502/503/504 — which are explicitly about upstream failures the caller can act on. Branch the 5xx path: keep 500 generic, include err.Error() in the body for 502/503/504. Server-side slog/OTel/Sentry reporting is unchanged. * Classify OCI pull errors into sharper HTTP status codes Registry.Pull failures in getContentFromOCI and installFromOCI were all mapped to a flat 502 Bad Gateway, so a 401 from GHCR, a missing manifest, a 429, and a network outage all looked identical to the caller. Add classifyPullError to inspect oras-go errors: context.DeadlineExceeded/Canceled → 504; *errcode.ErrorResponse 401/403 → 401, 404 → 404, 429 → 429, other 4xx/5xx → 502; errdef.ErrNotFound → 404; fallback → 502. Wire into content.go and install_oci.go at the Pull call sites. 4xx classifications flow through the unchanged 4xx handler path so auth/not-found errors surface verbatim without relying on the 5xx body change. * Fall back to registry-declared git package when OCI pull fails A content-preview request for an OCI ref that also appears in the skill registry with a git package was returned as a flat error as soon as the OCI pull failed, even though the catalog declared a perfectly good git mirror alongside the OCI artifact. Add resolveGitFallbackForOCIRef in registry.go. It searches the catalog by the refs tail path segment, keeps entries whose OCI package identifier parses to the same repository path (tag/digest agnostic, so :0.1.0 and :latest match), and returns the single matching entry's pinned git:// URL. Ambiguous matches are deliberately skipped — refusing to guess is better than silently serving the wrong skill. Wire into GetContent: for an unambiguous OCI ref whose remote pull fails, try the git fallback before returning the OCI error. The existing name-based registry resolution for ambiguous refs is kept intact. * Document 401/404/429/504 on skills content and install endpoints Fixes A and B of this series widened the set of HTTP status codes both endpoints can return: 401 (registry auth), 404 (artifact missing), 429 (registry rate limit), and 504 (upstream pull timeout) on top of the existing 400/500/502. Add @Failure annotations for the new codes on installSkill and getSkillContent in pkg/api/v1/skills.go and regenerate docs/server/{docs.go,swagger.json,swagger.yaml} via `swag init -g pkg/api/server.go --v3.1 -o docs/server --parseDependencyLevel 1`. * Address golangci-lint feedback on skills content fallback Two issues reported by CI on #5014: - revive (content.go): drop the else after return in the git-fallback block and hoist the short declaration onto its own line. - unparam (registry.go): resolveGitFallbackForOCIRef never returns a non-nil error (search errors are swallowed as "no fallback available"), so narrow the signature to return just string and update the caller. --- docs/server/docs.go | 84 ++++++++- docs/server/swagger.json | 84 ++++++++-

For the +> architectural overview, see +> [Virtual MCP Server Architecture](10-virtual-mcp-architecture.md). + +This document describes the known capacity limits, configuration-driven +constraints, and operational considerations for Virtual MCP Server (vMCP) +deployments. Review this before scaling beyond a single replica. + +## Per-pod session cache + +Each vMCP pod maintains a **node-local LRU cache** capped at **1,000 concurrent +`MultiSession` entries** (source: +`pkg/vmcp/server/sessionmanager/factory.go:defaultCacheCapacity`). + +When the cache is full, the least-recently-used session is evicted via the +`onEvict` callback, which calls `sess.Close()` to tear down its backend +connections. Any request in flight at that moment fails. Subsequent requests +for the same session ID trigger a cache miss: the session manager calls +`factory.RestoreSession()`, which reconstructs the `MultiSession` from stored +metadata and re-establishes backend connections transparently. The client does +not need to reconnect unless the metadata itself has also expired. + +The cap exists to prevent unbounded memory growth: omitting `CacheCapacity` +from a `FactoryConfig` silently defaults to 1,000 rather than unbounded growth. +`CacheCapacity` is currently an internal field and is not exposed via the +VirtualMCPServer CRD. + +**Implication:** A single vMCP pod can serve at most ~1,000 simultaneous MCP +sessions. To handle more, add replicas and configure Redis session storage so +that session metadata is persisted and any pod can reconstruct the live session +(including its routing table) via `RestoreSession()` on demand. + +## Session TTL + +### vMCP server TTL (30 minutes) + +The vMCP server defaults to a **30-minute session TTL** +(`pkg/vmcp/server/server.go:defaultSessionTTL`). The TTL controls the lifetime +of **session metadata** in the storage layer, not the in-process `MultiSession` +runtime objects: + +- **Local storage (single replica):** session metadata is removed from + `LocalSessionDataStorage` after the TTL elapses with no access. The + corresponding in-process `MultiSession` (with its live backend connections) + remains in the node-local LRU cache until it is evicted by cache pressure or + explicit termination. +- **Redis storage (multi-replica):** see [Redis sliding-window TTL](#redis-sliding-window-ttl) below. + +When metadata expires, any subsequent request that references that session ID +will fail to restore the session (`RestoreSession()` finds no stored metadata) +and the client must reinitialize. Backend connections held by the cached +`MultiSession` are only released when the LRU cache evicts the entry or the +session is explicitly terminated. + +The TTL is configurable via `server.Config.SessionTTL` but is not currently +exposed through the operator CRD. + +### MCPServer proxy TTL (2 hours) + +The MCPServer proxy runner uses a separate, longer TTL of **2 hours** +(`pkg/transport/session/proxy_session.go:DefaultSessionTTL`). This applies to +the underlying SSE/streamable transport sessions, not the vMCP-level session +aggregation. + +### Redis sliding-window TTL + +When Redis session storage is enabled, every `Load` call issues a `GETEX` that +resets the key's TTL atomically +(`pkg/transport/session/storage_redis.go:NewRedisStorage` and the comment at +line 177). This means: + +- Active sessions are preserved indefinitely as long as they receive at least + one request per TTL window. +- Idle sessions expire automatically after the full TTL elapses with no access. +- There is no absolute maximum session lifetime enforced by Redis storage. + +### Session garbage collection + +| Trigger | Mechanism | +| ------- | --------- | +| Explicit termination (client disconnect, auth failure) | `DEL` issued immediately to Redis | +| Inactivity beyond TTL | Redis TTL expiry (automatic, no application-side action needed) | +| Pod-local cache eviction (LRU) | `onEvict` callback closes backend connections only; the Redis metadata key is **not** deleted and expires via TTL | + +## File descriptor limits + +Each open backend connection consumes one file descriptor on the vMCP pod. A +pod aggregating many MCP backends at high session concurrency can exhaust the +OS-level `nofile` limit before hitting the 1,000-session cache cap. + +The default Linux per-process `nofile` soft limit is typically 1,024. When this +limit is reached, new `connect()` calls fail with `EMFILE` ("too many open +files"), which surfaces as backend connection errors. + +**Estimate:** `concurrent_sessions × backends_per_session` file descriptors. +For example, 200 sessions each connecting to 3 backends requires ~600 fds, +plus fds for incoming client connections and internal pipes. + +The issue has been identified but the exact threshold depends on pod +configuration and backend topology. Raise the limit in the container spec or at +the node level via the container runtime before deploying at scale. + +## Redis sizing + +Session data is written on every new session (`Store`) and read on every +request (`Load` + `GETEX`). Redis is on the hot path. + +| Parameter | Default | Notes | +| --------- | ------- | ----- | +| Dial timeout | 5 s (`DefaultDialTimeout`) | `pkg/transport/session/redis_config.go` | +| Read timeout | 3 s (`DefaultReadTimeout`) | | +| Write timeout | 3 s (`DefaultWriteTimeout`) | | +| Key prefix | configurable | Must end with `:` to avoid collisions | + +**Memory:** Session payloads include the routing table and tool metadata. Rough +estimate: 10–50 KB per session depending on backend count and tool count. +Maximum concurrent session count across the fleet is `replicas × 1,000`. + +**Connection pools:** Each vMCP pod creates one go-redis client with its own +connection pool. No explicit `PoolSize` is configured +(`pkg/transport/session/storage_redis.go`), so go-redis applies its default of +`10 × GOMAXPROCS` connections per pool. Total Redis connections therefore scale +as `replicas × (10 × GOMAXPROCS)`. Size the Redis `maxclients` setting +accordingly, and tune `PoolSize` in `RedisConfig` if the default is too large +or too small for your workload. + +**Eviction policy:** Use `allkeys-lru` so Redis can shed stale sessions under +memory pressure rather than returning errors on new writes. + +**Persistence:** Redis persistence is not required for session storage. If the +Redis pod restarts, all active sessions are lost and MCP clients must reconnect. +For production deployments where session continuity is critical, use a +`StatefulSet` with a PVC and enable RDB/AOF persistence. + +## Stateful backends and pod restarts + +vMCP is a stateless proxy: it holds routing tables and tool aggregation state, +but the backend MCP servers own their own state (browser sessions, database +cursors, open files). + +When a vMCP pod restarts or is evicted: + +1. **Redis session storage is configured:** the routing table survives in Redis. + Clients can reconnect and resume the MCP session. However, any backend-side + state (Playwright browser context, open transaction, filesystem handle) is + **not recovered** — the backend connection was torn down without a graceful + MCP shutdown sequence. + +2. **Local storage only:** both the routing table and the backend connections + are lost. Clients must reinitialize completely. + +In both cases, **in-flight tool calls are lost without a response** when a pod +dies. Callers should implement retry logic with idempotency guards for any tool +invocations that modify external state. + +### Session affinity and multi-replica deployments + +Stateful backends require that all requests within a session reach the same +backend pod. The `VirtualMCPServer` CRD exposes `sessionAffinity: ClientIP` +(default), which instructs kube-proxy to sticky-route connections by source IP. + +This is unreliable when clients sit behind NAT, a corporate proxy, or a cloud +load balancer — all traffic appears to originate from the same IP, routing every +session to a single pod. For production stateful workloads, prefer vertical +scaling over horizontal scaling.

Extract it into a MutateAndPatchSpec[T] generic helper in cmd/thv-operator/pkg/controllerutil, siblinged with the existing MutateAndPatchStatus. The helper mirrors its sibling exactly -- same reflection-based nil-guard, same DeepCopy-then-mutate-then-Patch flow -- with two deliberate differences: - Uses MergeFromWithOptions(original, MergeFromWithOptimisticLock{}) so concurrent writers get 409-and-requeue instead of silent clobber. This is the property that defends spec.authzConfig, which the forthcoming authorization controller will own, from being zeroed on every reconcile. - No no-op short-circuit. MergeFromWithOptimisticLock always emits metadata.resourceVersion into the body, so the status helper's "body == {}" check never fires; and every current spec call site carries a real mutation. All five inline sites (mcpserver_controller.go finalizer add/remove and restart-annotation stamp; toolconfig_controller.go and mcpexternalauthconfig_controller.go config-hash stamps) adopt the helper. Pure refactor at the call sites -- no behavior change. Tests mirror the status helper's shape: happy-path + optimistic-lock wire signal, DeepCopy isolation, 409 Conflict propagation, nil-obj rejection, and disjoint-spec-field preservation (the regression guard that would fire if the helper were ever swapped back to r.Update). Existing TestMCPServerSpecPatchesAreOptimisticLock and the mcpserver_spec_patch_integration_test.go envtest remain green. The operator-rules section on spec/metadata patching is updated to reference the helper as the canonical pattern. * Address MoE review feedback on MutateAndPatchSpec Three of five review findings applied (two skipped with rebuttal in the PR thread): - Add TestMutateAndPatchSpec_NoOpMutateStillPatches. The existing AppliesMutationWithOptimisticLock test asserts resourceVersion is present in the body when a patch is issued; it cannot detect a short-circuit regression that issues zero patches. Pin the documented divergence from MutateAndPatchStatus (which DOES short-circuit) with a direct no-op-mutate wire-level assertion. - Fix the godoc "Typical usage" example in both patch.go and status.go to use the ctrlutil alias. operator.md already uses this alias, and every real caller aliases the package to avoid colliding with controller-runtime's own controllerutil package. patch.go is updated to match; status.go is brought along for symmetry. - Document that obj is mutated before Patch is issued, so on error the caller's in-memory copy is post-mutation. Callers must re-fetch rather than retrying in place. Added to both helpers. The standard reconciler return-and-requeue pattern is the correct retry path; the sentence names it explicitly so a future caller reading the doc does not invent an in-place retry loop. Also tightened the "don't use this for status" cross-reference in status.go to name the sibling MutateAndPatchSpec directly. --- .claude/rules/operator.md | 26 +- .../mcpexternalauthconfig_controller.go | 20 +- .../controllers/mcpserver_controller.go | 39 +-- .../controllers/toolconfig_controller.go | 18 +- cmd/thv-operator/pkg/controllerutil/doc.go | 1 + cmd/thv-operator/pkg/controllerutil/patch.go | 76 +++++ .../pkg/controllerutil/patch_test.go | 317 ++++++++++++++++++ cmd/thv-operator/pkg/controllerutil/status.go | 10 +- 8 files changed, 437 insertions(+), 70 deletions(-) create mode 100644 cmd/thv-operator/pkg/controllerutil/patch.go create mode 100644 cmd/thv-operator/pkg/controllerutil/patch_test.go diff --git a/.claude/rules/operator.md b/.claude/rules/operator.md index 1baae52975..ed9a79b470 100644 --- a/.claude/rules/operator.md +++ b/.claude/rules/operator.md @@ -75,11 +75,11 @@ so any field our local copy does not track (e.g. `spec.authzConfig` written by a separate authorization controller) gets zeroed on every reconcile. -Use an **optimistic-lock merge patch** instead.

The stale pod's apply can land after the fresh pod's and clobber the image, leaving the StatefulSet pinned to the old digest even after MCPServer.spec.image has been bumped. The operator now stamps MCPServer.metadata.generation into the RunConfig as a monotonic version. Proxyrunner threads it through to DeployWorkloadOptions. Before apply, the K8s runtime reads the existing StatefulSet's mcpserver-generation annotation; if it is strictly greater than ours, the apply is skipped. Otherwise our generation is stamped on the pod template and apply proceeds. Zero generation is the backward-compat signal and bypasses both the gate and the stamp, preserving existing behavior for callers that don't pass one.

Part of #5016. Closes #5027. Co-Authored-By: Claude Sonnet 4.6 * Fix lint issues and regenerate CLI docs - Rename pkg/llm types to drop LLM prefix (revive stutter: LLMConfig → Config, LLMOIDCConfig → OIDCConfig, etc.) - Fix unused cmd parameter in config show RunE (revive) - Use FormatJSON constant instead of raw "json" string (goconst) - Fix gci import ordering in pkg/config/config.go - Regenerate docs/cli/ for the new thv llm command group Co-Authored-By: Claude Sonnet 4.6 * changes from review --------- Co-authored-by: taskbot Co-authored-by: Claude Sonnet 4.6 --- cmd/thv/app/commands.go | 2 + cmd/thv/app/llm.go | 299 ++++++++++++++++++++++ pkg/config/config.go | 2 + pkg/llm/config.go | 143 +++++++++++ pkg/llm/config_test.go | 339 +++++++++++++++++++++++++ pkg/llm/doc.go | 18 ++ pkg/networking/utilities.go | 35 +++ pkg/networking/utilities_test.go | 128 ++++++++++ pkg/registry/auth/issuer_validation.go | 19 +- pkg/secrets/scoped.go | 7 +- pkg/secrets/scoped_test.go | 1 + 11 files changed, 974 insertions(+), 19 deletions(-) create mode 100644 cmd/thv/app/llm.go create mode 100644 pkg/llm/config.go create mode 100644 pkg/llm/config_test.go create mode 100644 pkg/llm/doc.go diff --git a/cmd/thv/app/commands.go b/cmd/thv/app/commands.go index 14fe7bc348..fad9b560c0 100644 --- a/cmd/thv/app/commands.go +++ b/cmd/thv/app/commands.go @@ -71,6 +71,7 @@ func NewRootCmd(enableUpdates bool) *cobra.Command { rootCmd.AddCommand(inspectorCommand()) rootCmd.AddCommand(newMCPCommand()) rootCmd.AddCommand(newVMCPCommand()) + rootCmd.AddCommand(newLLMCommand()) rootCmd.AddCommand(groupCmd) rootCmd.AddCommand(skillCmd) rootCmd.AddCommand(statusCmd) @@ -113,6 +114,7 @@ func IsInformationalCommand(args []string) bool { "mcp": true, "skill": true, "vmcp": true, + "llm": true, } return informationalCommands[command] diff --git a/cmd/thv/app/llm.go b/cmd/thv/app/llm.go new file mode 100644 index 0000000000..e071783efe --- /dev/null +++ b/cmd/thv/app/llm.go @@ -0,0 +1,299 @@ +// SPDX-FileCopyrightText: Copyright 2026 Stacklok, Inc. +// SPDX-License-Identifier: Apache-2.0 + +package app + +import ( + "context" + "encoding/json" + "fmt" + "os" + + "github.com/spf13/cobra" + + "github.com/stacklok/toolhive/pkg/auth/secrets" + "github.com/stacklok/toolhive/pkg/config" + "github.com/stacklok/toolhive/pkg/llm" + pkgsecrets "github.com/stacklok/toolhive/pkg/secrets" +) + +func newLLMCommand() *cobra.Command { + cmd := &cobra.Command{ + Use: "llm", + Hidden: true, + Short: "Manage LLM gateway authentication", + Long: `Configure and manage authentication for OIDC-protected LLM gateways. + +The llm command bridges AI coding tools to LLM gateways by handling OIDC +authentication transparently.

+0200 Subject: [PATCH 027/291] llm: extract shared OIDC config, move business logic to pkg/llm, add E2E tests (#5049) * llm: extract shared OIDC config, move business logic to pkg/llm, add E2E tests Three follow-up cleanups from the #5029 review (#5048): 1. Extract shared OIDC config type into pkg/oidc.ClientConfig. Both config.RegistryOAuthConfig and llm.OIDCConfig are now type aliases for this type, so field additions and validation changes apply to both authentication flows without drift. 2. Move business logic from the CLI layer into pkg/llm per the cli-commands convention. The config-set mutation/validation branch, the config-show text formatter, and the cached-token deletion logic all live in pkg/llm now. The CLI commands are thin wrappers that parse flags and delegate. 3. Add E2E tests for thv llm config set/show/reset, covering happy-path round-trips, HTTPS enforcement, incremental configuration, the not-configured message, and post-reset state. Co-Authored-By: Claude Sonnet 4.6 * llm: fix errcheck lint failures in Show method Show now returns an error and uses a writef closure to propagate the first write failure rather than ignoring io.Writer errors. The CLI caller is updated to return the error directly. Co-Authored-By: Claude Sonnet 4.6 * llm: skip token deletion for providers that can't list or delete Providers like the environment provider are read-only and cannot hold cached tokens, so calling ListSecrets on them would always produce a spurious warning during thv llm config reset. Check CanList/CanDelete capabilities first and treat non-capable providers as a no-op. Co-Authored-By: Claude Sonnet 4.6 * llm: add unit tests for SetFields, DeleteCachedTokens, and Show Covers the business logic introduced in manage.go: - SetFields: field mutation, partial vs full validation branching, invalid-value rejection - DeleteCachedTokens: capability no-ops (no CanList/CanDelete), empty-scope no-op, scoped deletion, error propagation - Show: not-configured message, required-field output, conditional audience line, configured-tools section Co-Authored-By: Claude Sonnet 4.6 * test(e2e): configure environment secrets provider in llm config tests Mirrors the pattern from cli_secrets_scoped_test.go to ensure the test suite never opens the user's real keychain or 1Password. The environment provider is non-interactive and read-only, so DeleteCachedTokens is a no-op, keeping the tests fully hermetic.

For OAuth-protected backends, a 401/403 challenge is the expected response to an unauthenticated probe and proves the backend is reachable, its auth layer works, and the network path is sound. Map auth errors to BackendHealthy when the backend has an outgoing auth strategy configured; keep BackendUnauthenticated only as a narrower misconfiguration signal (backend demands auth, none configured). This unblocks discovery from excluding OAuth-protected backends from capability aggregation (resolves the TODO at discovery/middleware.go). Drop the `|| BackendUnauthenticated` clause from /status since the state now represents misconfig rather than routability. Legacy PR #4866 routability semantics in monitor.go are left in place with a TODO for a follow-up revert; they touch operator controllers and warrant a separate PR.

New pkg/llm/proxy package: - proxy.go: httputil.ReverseProxy wrapper that strips incoming Authorization headers, injects fresh OIDC tokens, and forwards to the configured gateway. Binds listener in New() so Addr() is valid before Start(). Loopback guard rejects non-localhost listen addrs. SSE streaming works without buffering (FlushInterval: -1). Graceful 5-second shutdown on context cancellation. - daemon.go: PID-file lifecycle (IsRunning, Stop, StartDetached). StartDetached forks the current binary with TOOLHIVE_DETACHED=1, redirecting stdout/stderr to the XDG log file. - daemon_unix.go / daemon_windows.go: platform-specific processAlive and SysProcAttr helpers via build tags. CLI wiring (cmd/thv/app/llm.go): - thv llm proxy start [--foreground]: background by default, foreground with --foreground or when running as detached child. - thv llm proxy stop: sends SIGTERM via process.KillProcess and removes PID file.

In the preemptive window the inner ReuseTokenSource returned the same cached real token, causing preemptiveTokenSource to shift an already-expired expiry, so every Token() call re-entered the inner chain instead of one refresh per window. Fix: build the raw refresher directly (NewResourceTokenSource for the resource path, config.TokenSource for the non-resource path) without an inner ReuseTokenSource, then stack: ReuseTokenSource(nil, preemptive{Persisting{raw}}). Extract oauth2ConfigFrom helper to reuse the already-discovered flowCfg in performBrowserFlow without a second OIDC round-trip. 2. Stale _AT cache after refresh token rotation: makeTokenPersister wrote the new refresh token but left the _AT access-token cache entry unchanged. A concurrent process could read the stale _AT between the write and the next Token() call. Fix: after SetSecret for the refresh token succeeds, overwrite the _AT entry with an empty string so the next Token() call falls through to tier 2. Adds a regression test verifying that multiple Token() calls within the preemptive window produce exactly two inner calls: one for the initial short-lived token and one for the preemptive refresh that yields a fresh cached token.

The non-JSON content-type and missing client_id cases were already covered; this commit adds the cap test. The test sends a body padded well past 1 MB and verifies the call returns promptly without hanging or panicking — a future refactor that removes or raises the cap would break the JSON decode and surface the regression immediately. --- docs/remote-mcp-authentication.md | 6 +- docs/server/docs.go | 2 +- docs/server/swagger.json | 2 +- docs/server/swagger.yaml | 4 +- pkg/auth/discovery/dcr_request.go | 29 + pkg/auth/discovery/discovery.go | 24 +- pkg/auth/discovery/discovery_test.go | 2 +- pkg/auth/github_provider.go | 4 +- pkg/auth/oauth/dynamic_registration_test.go | 748 ----------------- pkg/auth/oauth/flow.go | 2 +- pkg/auth/oauth/oidc.go | 7 +- pkg/auth/oauth/oidc_test.go | 2 +- pkg/auth/token.go | 9 +- pkg/auth/token_test.go | 2 +- pkg/auth/tokenexchange/exchange.go | 28 +- pkg/auth/tokenexchange/exchange_test.go | 42 +- pkg/auth/tokenexchange/middleware.go | 22 +- pkg/auth/well_known.go | 2 +- pkg/authserver/server/handlers/discovery.go | 2 +- .../server/handlers/handlers_test.go | 2 +- pkg/authserver/server/registration/dcr.go | 4 +- .../server/registration/dcr_test.go | 4 +- pkg/authserver/upstream/oauth2.go | 2 +- pkg/authserver/upstream/oidc.go | 2 +- pkg/authserver/upstream/oidc_test.go | 2 +- pkg/networking/utilities.go | 14 +- pkg/oauth/doc.go | 18 - pkg/{oauth => oauthproto}/constants.go | 27 +- .../dcr.go} | 170 ++-- pkg/oauthproto/dcr_test.go | 753 ++++++++++++++++++ pkg/{oauth => oauthproto}/discovery.go | 2 +- pkg/{oauth => oauthproto}/discovery_test.go | 2 +- pkg/oauthproto/doc.go | 20 + pkg/{oauth => oauthproto}/errors.go | 2 +- pkg/oauthproto/locality.go | 21 + pkg/{oauth => oauthproto}/redirect.go | 2 +- pkg/{oauth => oauthproto}/redirect_test.go | 2 +- 37 files changed, 1013 insertions(+), 975 deletions(-) create mode 100644 pkg/auth/discovery/dcr_request.go delete mode 100644 pkg/auth/oauth/dynamic_registration_test.go delete mode 100644 pkg/oauth/doc.go rename pkg/{oauth => oauthproto}/constants.go (75%) rename pkg/{auth/oauth/dynamic_registration.go => oauthproto/dcr.go} (75%) create mode 100644 pkg/oauthproto/dcr_test.go rename pkg/{oauth => oauthproto}/discovery.go (99%) rename pkg/{oauth => oauthproto}/discovery_test.go (99%) create mode 100644 pkg/oauthproto/doc.go rename pkg/{oauth => oauthproto}/errors.go (98%) create mode 100644 pkg/oauthproto/locality.go rename pkg/{oauth => oauthproto}/redirect.go (99%) rename pkg/{oauth => oauthproto}/redirect_test.go (99%) diff --git a/docs/remote-mcp-authentication.md b/docs/remote-mcp-authentication.md index a7e053975e..f67a43f034 100644 --- a/docs/remote-mcp-authentication.md +++ b/docs/remote-mcp-authentication.md @@ -48,13 +48,13 @@ ToolHive implements BOTH discovery mechanisms required by the MCP specification: - Accepts the authoritative issuer from well-known endpoints per RFC 8414 #### 4.

Reads from --in or stdin, writes to --out, stdout, or in place with a .bak backup. The CLI is a thin wrapper around `pkg/registry.ConvertJSON`, which produces schema-validated upstream JSON. In-place writes go through a temp file + fsync + rename so a crash mid-write can't corrupt the input, and the helper refuses to clobber an existing .bak so a previous good copy is never silently destroyed. This lands ahead of the legacy-format removal (separate PR) so the migration error users will see there can point at this command. --- .codespellrc | 2 +- cmd/thv/app/registry_convert.go | 167 +++++++++++ cmd/thv/app/registry_convert_test.go | 132 +++++++++ docs/cli/thv_registry.md | 1 + docs/cli/thv_registry_convert.md | 47 +++ pkg/registry/convert.go | 85 ++++++ pkg/registry/convert_test.go | 409 ++++++++++++++++++++++++++ test/e2e/cli_registry_convert_test.go | 105 +++++++ 8 files changed, 947 insertions(+), 1 deletion(-) create mode 100644 cmd/thv/app/registry_convert.go create mode 100644 cmd/thv/app/registry_convert_test.go create mode 100644 docs/cli/thv_registry_convert.md create mode 100644 pkg/registry/convert.go create mode 100644 pkg/registry/convert_test.go create mode 100644 test/e2e/cli_registry_convert_test.go diff --git a/.codespellrc b/.codespellrc index 29a423f9c6..b1d5725306 100644 --- a/.codespellrc +++ b/.codespellrc @@ -1,3 +1,3 @@ [codespell] -ignore-words-list = NotIn,notin,AfterAll,ND,aks,deriver,te,clientA,AtMost,atmost +ignore-words-list = NotIn,notin,AfterAll,ND,aks,deriver,te,clientA,AtMost,atmost,convertIn skip = *.svg,*.mod,*.sum diff --git a/cmd/thv/app/registry_convert.go b/cmd/thv/app/registry_convert.go new file mode 100644 index 0000000000..52b8bee52d --- /dev/null +++ b/cmd/thv/app/registry_convert.go @@ -0,0 +1,167 @@ +// SPDX-FileCopyrightText: Copyright 2025 Stacklok, Inc. +// SPDX-License-Identifier: Apache-2.0 + +package app + +import ( + "errors" + "fmt" + "io" + "os" + "path/filepath" + + "github.com/spf13/cobra" + + "github.com/stacklok/toolhive/pkg/registry" +) + +var ( + convertIn string + convertOut string + convertInPlace bool + convertNoBackup bool +) + +var registryConvertCmd = &cobra.Command{ + Use: "convert", + Short: "Convert a legacy registry file to the upstream MCP format", + Long: `Convert a legacy ToolHive registry JSON file to the upstream MCP registry format. + +Reads from --in (or stdin) and writes to --out (or stdout).

When the upstream sets an explicit Content-Length (e.g. playwright-mcp on streamable-http), the rewritten body usually has a different size and net/http rejects the write with "http: wrote more than the declared Content-Length", sending zero body bytes to the client. The MCP handshake then stalls at tools/list. Drop Content-Length in WriteHeader so Go falls back to chunked transfer encoding, which the MCP Streamable HTTP transport spec permits. Fixes #5075 Co-Authored-By: Claude Opus 4.7 (1M context) * Add regression test for Content-Length stripping Without this test, a future refactor could silently revert the toolFilterWriter.WriteHeader fix and reintroduce #5075 — TestToolFilterWriter_Flush exercises WriteHeader but never asserts that an inbound Content-Length is stripped. Adds a focused table test covering JSON+Content-Length, SSE+Content-Length, and the no-Content-Length pass-through case.

The auto-detect helpers, deprecation warnings, and duplicated format-discriminator code make the parsing path harder to reason about and earn nothing. - pkg/registry/upstream_parser.go: drop isUpstreamFormat, parseRegistryAutoDetect, and the legacy fallback branch; rename the upstream-only parser to parseRegistryData. Detect legacy input up front and return errLegacyFormat with a migration hint pointing at `thv registry convert` (added in #5071) — without this, Go's JSON decoder silently produces an empty UpstreamRegistry, leaving callers with no servers and no error. - pkg/registry/provider_{local,remote}.go: collapse the auto-detect branches into a single upstream parse and remove the legacy-format warning. - pkg/config/registry.go: drop the duplicated isUpstreamRegistryFormat / registryHasServers helpers; both validators now parse only into UpstreamRegistry. Surface the same migration hint when a legacy file or URL is supplied to set-registry-file/set-registry-url. - Convert legacy fixtures across pkg/registry, pkg/config, and pkg/api/v1 unit tests to the upstream format. - docs/registry/schema.md: drop the legacy-schema section, point at the upstream schemas in toolhive-core, and document the migration command. Depends on #5071 (the converter) so the migration hint resolves to a real command. * Address review follow-ups for legacy-format removal - Convert examples/registry-with-remote-servers.json to upstream format. The legacy version was rejected at runtime and could not be auto-migrated by `thv registry convert` because it used lowercase `tier: "community"`, which fails the upstream schema's enum. - Refresh docs/registry/schema.md test descriptions; the legacy-schema tests they referenced were deleted in this PR. - Surface the migration hint from RemoteRegistryProvider's connectivity check so a remote URL serving a legacy file produces the same hint as the local-file path, instead of "no servers or groups". - Extract pkg/registry/legacyhint as a leaf package shared by pkg/registry and pkg/config so the legacy-detection helper and migration message live in one place.

packager errors as 400 in skill build handler (#5076) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Bump github.com/stacklok/toolhive-core to v0.0.17 v0.0.17 introduces sentinel errors in oci/skills (ErrSkillMDMissing, ErrInvalidFrontmatter, ErrInvalidSkillDir, ErrInvalidSkillFile, ErrTooManyFiles, ErrSkillTooLarge) so callers can classify packager failures with errors.Is instead of matching error strings. Pulled in ahead of the build-handler refactor that consumes them. * Classify packager errors as 400 in skill build handler POST /api/v1beta/skills/build previously surfaced every packager failure — including user-input mistakes like a missing SKILL.md or a malformed frontmatter — as 500 Internal Server Error with no body, generating Sentry noise on what is plainly bad input. Wrap the s.packager.Package error with an errors.Is switch over the six toolhive-core v0.0.17 sentinels and map each one to 400 with the packager's message preserved. Anything else stays a 500. Add five TestBuild cases that mock the packager returning a wrapped sentinel and assert both the HTTP code and errors.Is on the sentinel, covering the limits the toolhive-side validator misses (symlink in skill dir, oversized dir). --- go.mod | 2 +- go.sum | 4 +- pkg/skills/skillsvc/build.go | 12 +++++ pkg/skills/skillsvc/build_test.go | 86 ++++++++++++++++++++++++++++--- 4 files changed, 95 insertions(+), 9 deletions(-) diff --git a/go.mod b/go.mod index 3819e73c7e..10acfa6028 100644 --- a/go.mod +++ b/go.mod @@ -46,7 +46,7 @@ require ( github.com/shirou/gopsutil/v4 v4.26.2 github.com/spf13/viper v1.21.0 github.com/stacklok/toolhive-catalog v0.20260423.0 - github.com/stacklok/toolhive-core v0.0.16 + github.com/stacklok/toolhive-core v0.0.17 github.com/stretchr/testify v1.11.1 github.com/swaggo/swag/v2 v2.0.0-rc5 github.com/tailscale/hujson v0.0.0-20260302212456-ecc657c15afd diff --git a/go.sum b/go.sum index 9b41219034..f873a3359f 100644 --- a/go.sum +++ b/go.sum @@ -799,8 +799,8 @@ github.com/spf13/viper v1.21.0 h1:x5S+0EU27Lbphp4UKm1C+1oQO+rKx36vfCoaVebLFSU= github.com/spf13/viper v1.21.0/go.mod h1:P0lhsswPGWD/1lZJ9ny3fYnVqxiegrlNrEmgLjbTCAY= github.com/stacklok/toolhive-catalog v0.20260423.0 h1:W3qbLqbLhPqclYGrxYtm5jDYurjcEMRAhr7k/qfxm4s= github.com/stacklok/toolhive-catalog v0.20260423.0/go.mod h1:bfIGimrf8SJJGT3+WcJmFKJ3JB2vz9RPykn2r6nKVNw= -github.com/stacklok/toolhive-core v0.0.16 h1:Td/o/zrO3Pbr6tkx4r0k8Bqn9DySlwgah2vknE8tj5A= -github.com/stacklok/toolhive-core v0.0.16/go.mod h1:iHp39rCHZxXzU5FmXKK9aoH48NE+K0ob+MtdTS9CvAk= +github.com/stacklok/toolhive-core v0.0.17 h1:yGKXntWyw5ZO5GMxfSHi9doJhSXA8w5ORSXWveJ3OGc= +github.com/stacklok/toolhive-core v0.0.17/go.mod h1:o/zVzleR/xNCNXdTwNx8A41hApu0GZsHZS42qcXYUr8= github.com/stretchr/objx v0.1.0/go.mod h1:HFkY916IF+rwdDfMAkV7OtwuqBVzrE8GR6GFx+wExME= github.com/stretchr/objx v0.1.1/go.mod h1:HFkY916IF+rwdDfMAkV7OtwuqBVzrE8GR6GFx+wExME= github.com/stretchr/objx v0.2.0/go.mod h1:qt09Ya8vawLte6SNmTgCsAVtYtaKzEcn8ATUoHMkEqE= diff --git a/pkg/skills/skillsvc/build.go b/pkg/skills/skillsvc/build.go index bcfe32f1c2..eb89da02a1 100644 --- a/pkg/skills/skillsvc/build.go +++ b/pkg/skills/skillsvc/build.go @@ -40,6 +40,18 @@ func (s *service) Build(ctx context.Context, opts skills.BuildOptions) (*skills. } result, err := s.packager.Package(ctx, opts.Path, ociskills.DefaultPackageOptions()) if err != nil { + // User-input failures (missing SKILL.md, bad frontmatter, symlinks, + // size/count limits, unreadable directory) are surfaced as 400 with + // the packager's message intact.

Adding a new tool requires only implementing the interface and calling Register() from init() — no changes to orchestration are needed. Token-helper adapters (claude-code, gemini-cli) patch their config files to invoke "thv llm token" on demand and point at the upstream gateway URL. Proxy-mode adapters (cursor, vscode, xcode) patch their config files to point at the localhost reverse proxy with a placeholder API key. Replaces the "not implemented" stubs in thv llm setup/teardown with the real orchestration logic: setup detects installed tools and applies all adapters, teardown reverts them and (optionally) purges cached tokens. All config file writes are atomic (temp-file + rename). VS Code and Cursor settings use literal dotted key names rather than nested maps; a separate revertFlatJSONFile helper handles that distinction.

Landing these first is a prerequisite for shrinking the JWT Bearer PR under the 400-LOC soft cap in CLAUDE.md. pkg/oauthproto/grants.go consolidates: - A process-wide *http.Client with 30s / 10s / 10s timeouts, matching pkg/auth/oauth/dynamic_registration.go. Deliberately not routed through pkg/networking.NewHttpClientBuilder, whose SSRF dialer control blocks 127.0.0.1 and would break every httptest.NewServer test as well as localhost-hosted IdPs used in development. - TokenResponse plus ParseTokenResponse as the single entry point for decoding a token endpoint body, enforcing RFC 6749 Sections 5.1 and 5.2 together. Body is decoded unconditionally so a 2xx response that carries an "error" field still routes to *oauth2.RetrieveError, as the spec requires and as x/oauth2 internal.RetrieveToken does. - The tokenJSON wire struct and expirationTime.UnmarshalJSON are copied (with attribution) from x/oauth2/internal/token.go so that expires_in decodes from both JSON numbers and JSON strings. Naively embedding *oauth2.Token into TokenResponse would fail on the string form and silently leave Expiry zero; composition keeps the public surface stable and avoids leaking oauth2.Token's Valid / Extra / Type methods. - NewFormRequest and DoTokenRequest mirror x/oauth2/internal helpers so that each grant's Token() method collapses to a request build plus a single high-level execute-and-parse call. DoTokenRequest reads the body through an io.LimitReader capped at 1 MiB and then closes without draining, matching x/oauth2/internal/token.go. Draining via io.Copy(io.Discard, resp.Body) is deliberately avoided because it would be unbounded on oversized or never-terminating bodies and would defeat the memory cap; the tradeoff is that net/http cannot reuse the underlying connection when a response exceeds the cap, which is acceptable for a pathological response. This diverges from .claude/rules/go-style.md's generic drain-before- close guidance, which presumes the body is not size-capped. pkg/oauthproto/oauthtest provides exported ResponseBuilder and ErrorResponseBuilder types so both the grant subpackages and their callers can share the same JSON fixtures instead of drifting. No callers yet; pkg/auth/tokenexchange continues to use its local copies. A follow-up commit rewires tokenexchange onto these shared helpers and absorbs the RetrieveError migration that is already queued on the JWT Bearer feature branch. task test and task lint-fix are clean. pkg/oauthproto coverage is 97.8%, up from the 93.9% baseline. --- pkg/oauthproto/constants.go | 14 +- pkg/oauthproto/grants.go | 348 ++++++++++ pkg/oauthproto/grants_test.go | 912 +++++++++++++++++++++++++++ pkg/oauthproto/oauthtest/fixtures.go | 131 ++++ 4 files changed, 1403 insertions(+), 2 deletions(-) create mode 100644 pkg/oauthproto/grants.go create mode 100644 pkg/oauthproto/grants_test.go create mode 100644 pkg/oauthproto/oauthtest/fixtures.go diff --git a/pkg/oauthproto/constants.go b/pkg/oauthproto/constants.go index b32592ef6a..f51caa1048 100644 --- a/pkg/oauthproto/constants.go +++ b/pkg/oauthproto/constants.go @@ -3,6 +3,8 @@ package oauthproto +import "time" + // Well-known endpoint paths as defined by RFC 8414, OpenID Connect Discovery 1.0, and RFC 9728. const ( // WellKnownOIDCPath is the standard OIDC discovery endpoint path @@ -49,7 +51,7 @@ const ( // Token type URNs as defined by RFC 8693. // -//nolint:gosec // G101: False positive - these are OAuth2 URN identifiers, not credentials +//nolint:gosec // G101: these are RFC 8693 token-type URN identifiers, not credentials const ( // TokenTypeAccessToken indicates an OAuth 2.0 access token (RFC 8693 Section 3).

Co-Authored-By: Claude Opus 4.6 (1M context) * Add run from registry support in TUI Allow launching MCP servers directly from the registry browser. Press 'r' in the registry detail view to open a form with the workload name and environment variable fields pre-populated from registry metadata. Secret fields use password masking. On submit, the TUI spawns 'thv run' as a subprocess and refreshes the workload list on completion. Co-Authored-By: Claude Opus 4.6 (1M context) * Cap tool description to 2 lines in inspector Truncate long tool descriptions in the inspector form to 2 lines with an ellipsis and [i] hint to view the full text in the detail modal. This prevents verbose MCP tool descriptions from pushing form fields off screen. Co-Authored-By: Claude Opus 4.6 (1M context) * Sort environment variables in info panel Sort environment variable keys alphabetically before rendering in the server info panel. Go maps have non-deterministic iteration order, which caused env vars to shuffle on every 5-second refresh cycle. Co-Authored-By: Claude Opus 4.6 (1M context) * Add unit tests for TUI pure functions Cover core logic functions with 130+ subtests across 8 test files: registry (sanitize, filter), view helpers (wrap, truncate, count), inspector (required set, field values, result formatting), logs (split, diff), log formatting (parse, level style), JSON tree (parse, flatten, collapse, roundtrip), search (highlight), and form helpers (navigation, blur). Co-Authored-By: Claude Opus 4.6 (1M context) * Fix security, memory, and usability issues in TUI Escape single quotes in buildCurlStr to prevent shell injection when the generated curl command is pasted into a terminal (CodeQL finding). Cap log buffers at 10k lines to prevent unbounded memory growth during long-running sessions. Bound horizontal scroll to the longest line. Extract shared newBackendClientAndTarget helper to deduplicate fetchTools/callTool setup. Remove unused parameter from renderRegistryOverlay. Complete the --help keybinding list (8 → 20 bindings). Document diffLines duplicate-line limitation and secrets process-visibility tradeoff. Co-Authored-By: Claude Opus 4.6 (1M context) * Escape shell metacharacters in buildRunCmd clipboard output Single-quote and escape all dynamic values from registry metadata (server name, transport, permission profile, env var names) in the generated `thv run` command that is copied to clipboard. Without escaping, a malicious registry entry containing shell metacharacters could lead to arbitrary command execution when the user pastes the command into a terminal. Co-Authored-By: Claude Opus 4.6 (1M context) * Use suffix sequence matching in diffLines for duplicate log lines Replace single-line matching with a 3-line suffix sequence match to reliably detect the boundary between old and new log lines when the same message repeats. Falls back to single-line matching when prev has fewer than 3 lines or no sequence match is found. Co-Authored-By: Claude Opus 4.6 (1M context) * Address Copilot review comments in TUI - Fix --secret flag format: pass secret env vars as --env NAME=VALUE since the run form collects actual values, not secrets-manager references - Add height < 2 guard in View() to prevent index-out-of-bounds panic on very small terminal resize events - Remove unused base-frame parameter from renderHelpOverlay and update its comment to match actual behavior - Fix three UTF-8 backspace bugs (registry filter, sidebar filter, inspector tool filter) that sliced by byte instead of by rune - Rewrite highlightSubstring to operate on rune indices so Unicode case mappings that change byte length cannot desync slice positions - Add defer in tuiCmdFunc to emit OSC 111 background-colour reset on abnormal exit paths (panics) that bypass View()'s quitting branch - Add unit tests for buildRunCmd covering transport, permission-profile, required/optional env vars, and combined flag cases Co-Authored-By: Claude Sonnet 4.6 * Fix golangci-lint failures in TUI code - gci: fix import block ordering in actions.go and json_tree.go - exhaustive: add all ContentType cases to formatInspResult switch; extract per-panel status bar hint helpers so renderStatusBar switch covers every activePanel value explicitly - gocyclo: suppress with nolint on inherently complex key-handler and renderer switch statements (handleInspectorKey, handleNormalKey, handleMsg, renderMain, renderInspResponse, renderStatusBar, renderJSONItem) - gosec G115: annotate uintptr→int conversions in help.go and spinner.go - gosec G204: annotate exec.CommandContext in actions.go - lll: break long runFromRegistry signature onto multiple lines - revive: add godoc comment to Model.View; rename unused width param to _ in renderTools - staticcheck: replace sb.WriteString(fmt.Sprintf(...)) with fmt.Fprintf - thelper: add t.Helper() to inline check closures in inspector_test.go - unparam: remove n parameter from makeFormFields (always 3) - unused: delete unreachable rebuildLogSearch and rebuildProxyLogSearch Co-Authored-By: Claude Sonnet 4.6 * Generate CLI docs for thv tui command Co-Authored-By: Claude Sonnet 4.6 * Fix bugs found in post-merge review - Guard runFormSubmit against empty fields slice before indexing fields[0] - Initialize toolsView viewport in New() to avoid zero-width renders before the first WindowSizeMsg arrives - Cap inspector slog buffer at 500 lines (same pattern as logLines) - Validate that env var and secret keys do not contain '=' before constructing --env NAME=VALUE arguments - Clarify buildRunCmd comment: --secret references a secrets-manager entry, not an inline value; distinguish from runFromRegistry --env path Co-Authored-By: Claude Sonnet 4.6 * Fix remaining golangci-lint failures - errcheck: wrap deferred fmt.Fprint to discard return values - gci/gofmt: fix struct field alignment in keys.go (Space, CopyNode); add missing final newline in model.go; add spaces around arithmetic operators in view.go lipgloss chain - gosec G115: annotate three IsTerminal uintptr→int casts in spinner.go - lll: shorten nolint comment in view_inspector.go to fit 130-char limit - staticcheck QF1012: replace remaining sb.WriteString(fmt.Sprintf(...)) with fmt.Fprintf in help.go (footerHint, RenderCommandUsage, renderParentHelp) Co-Authored-By: Claude Sonnet 4.6 * Replace vmcp BackendClient with mcp-go SDK in TUI The TUI talked to MCP servers through the vMCP aggregation client, which is designed for 1:N multi-backend routing. This was overkill for the TUI's 1:1 workload interaction: every operation created a new client, ran the full initialize handshake, loaded four auth strategies (all resolving to unauthenticated for localhost), and wrapped the transport in unused middleware layers. Switch to using the mark3labs/mcp-go SDK directly with a persistent client per selected workload. The client is created once on workload selection, reused for ListTools and CallTool, and closed when the user switches workloads or exits. This removes the vmcp dependency from pkg/tui/ entirely. Co-Authored-By: Claude Opus 4.6 (1M context) * Mark TUI command as experimental in help output Co-Authored-By: Claude Opus 4.6 (1M context) * Regenerate CLI docs after TUI experimental tag Co-Authored-By: Claude Opus 4.6 (1M context) * Coerce inspector field values to JSON Schema types inspFieldValues sent every form value as a string regardless of the tool's declared schema type, causing servers that validate input to reject calls with non-string parameters. Add parseFieldValue to convert strings to the correct Go type (int64, float64, bool, or parsed JSON for arrays/objects) before building the arguments map. Also validate required fields before the call and focus the first offending field on error so users get immediate feedback instead of a confusing server-side rejection. Co-Authored-By: Claude Opus 4.6 (1M context) * Remove redundant inspector test cases Drop test cases that exercise the same code paths already covered by other cases: duplicate default-branch hits, same-branch boolean variants, stdlib behavior, and per-type coercion cases in TestInspFieldValues that duplicate TestParseFieldValue coverage. Co-Authored-By: Claude Opus 4.6 (1M context) * Move MCP client connect off the Update goroutine createMCPClient and connectMCPClient ran synchronously inside maybeLoadTools, which is called from Update. This blocked the entire TUI (input, ticks, log streaming) until the MCP server responded or timed out, violating Bubble Tea's non-blocking Update contract. Move the connect into a tea.Cmd that runs on a background goroutine and posts mcpClientReadyMsg on completion. The handler sets the client and kicks off the tools fetch, keeping Update responsive throughout. Co-Authored-By: Claude Opus 4.6 (1M context) * Guard runesTruncate against non-positive width A very small terminal width can drive the truncation limit to zero or below, causing a panic on the negative slice index r[:n-1]. Return the ellipsis immediately when n <= 1. Co-Authored-By: Claude Opus 4.6 (1M context) * Cancel log and proxy-log contexts on quit The quit handler closed the MCP client but left log and proxy-log streaming goroutines running until process exit. Cancel both context functions so background goroutines stop promptly. Co-Authored-By: Claude Opus 4.6 (1M context) * Remove dead CLIHandler and document TUILogHandler limits CLIHandler was unused outside its own file. Remove it and its dependencies. Document that TUILogHandler is an end-of-pipeline handler whose WithAttrs/WithGroup methods intentionally return the receiver unchanged rather than accumulating state. Co-Authored-By: Claude Opus 4.6 (1M context) * Extract shared MCP client package The TUI and CLI each had their own MCP client creation logic with divergent behavior: the TUI hardcoded version "1.0.0" and skipped auto-detection, while the CLI had the full implementation. Extract the shared logic into pkg/mcp/client with a single Connect function that handles transport selection, auto-detection, and the initialize handshake using the real ToolHive version. Both the CLI and TUI now delegate to this package. Co-Authored-By: Claude Opus 4.6 (1M context) * Replace runFromRegistry subprocess with in-process manager call runFromRegistry shelled out to thv run via os/exec, leaking secrets in /proc/cmdline and creating a drift surface between TUI and CLI behavior. The TUI already holds a workloads.Manager for stop, restart, and delete operations. Build a RunConfig from registry metadata using the same RunConfigBuilder pattern as the CLI and call the manager directly. Use context.WithoutCancel so launched workloads outlive the TUI session. Co-Authored-By: Claude Opus 4.6 (1M context) * Replace filterRegistryItems with provider.SearchServers filterRegistryItems reimplemented substring matching that provider.SearchServers already provides, and missed tag matching. Delegate to SearchServers so the TUI and thv search share the same filtering semantics. The provider's in-memory cache makes per- keystroke calls safe without network overhead. Co-Authored-By: Claude Opus 4.6 (1M context) * Surface log polling errors and increase fetch window Silent error swallowing in StreamWorkloadLogs left the log pane frozen on workload removal or runtime restart. Emit errors as visible log lines with exponential backoff (1s to 5s) to prevent tight-looping. Increase logFetchLines from 50 to 500 to reduce line loss on chatty streams. Co-Authored-By: Claude Opus 4.6 (1M context) * Tighten tautological test assertions TestLevelStyle, TestHighlightSubstring, and TestFormatInspResult only asserted NotEmpty or Contains(plainText), which would pass with broken implementations. Add ANSI escape verification, cross- level differentiation, and content-specific assertions. Add main_test.go to force ANSI256 color profile in test environments where lipgloss strips styling. Co-Authored-By: Claude Opus 4.6 (1M context) * Stop search prompt from swallowing n and N keys handleSearchKey matched SearchNext/SearchPrev (bound to n/N) before the rune input case, so typing n or N during search query entry navigated matches instead of inserting the character. Remove those cases from the active-search handler; match navigation is already handled in handleNormalKey after the user commits with Enter. Co-Authored-By: Claude Opus 4.6 (1M context) * Remove redundant required placeholder text The "(required)" suffix in the form field placeholder vanishes when the user starts typing. The label already renders a persistent red asterisk via renderFormField for required fields, making the placeholder suffix redundant. Co-Authored-By: Claude Opus 4.6 (1M context) * Add comment explaining best-effort curl preview args Co-Authored-By: Claude Opus 4.6 (1M context) * Fix lint errors after merging main Handle WorkloadStatusPolicyStopped in exhaustive switch statements, fix gci import grouping for toolhive-core imports, and reduce buildRunConfigFromRegistry cyclomatic complexity by extracting validateAndMergeEnvVars and permissionProfileName helpers. Co-Authored-By: Claude Opus 4.6 (1M context) * Fix gci import grouping for toolhive-core toolhive-core shares the github.com/stacklok/toolhive prefix and belongs in the same import group as toolhive packages, not with external dependencies. Co-Authored-By: Claude Opus 4.6 (1M context) * Filter registry by short name when query starts with / Typing /github in the registry browser now matches only the short name after the last slash, so io.github.stacklok/github matches but io.github.stacklok/something-else does not. Queries without the / prefix still use SearchServers for full-text matching across name, description, and tags. Co-Authored-By: Claude Opus 4.6 (1M context) * Remove trailing newlines flagged by linter Co-Authored-By: Claude Opus 4.6 (1M context) * Reset terminal background on SIGTERM/SIGINT The OSC 11 sequence that sets the TUI background persists after exit if the process is killed by a signal before the defer or View() can emit the reset. Install a signal handler that prints the OSC 111 reset before re-raising, covering terminal multiplexers and Ctrl+C during hangs. Co-Authored-By: Claude Opus 4.6 (1M context) * Handle clipboard errors and keep filter active after Enter clipboard.WriteAll errors were silently ignored while showing a success notification, misleading users on platforms without clipboard support. Check the error and show a failure notification when it occurs. filteredWorkloads only applied the filter while the prompt was active, so pressing Enter dismissed both the prompt and the filter. Filter whenever the query is non-empty so users can navigate the filtered list after confirming.

ce4ee1ff5a7fda589b9fc43a439159e8b9250770 Mon Sep 17 00:00:00 2001 From: Yolanda Robla Mota Date: Tue, 28 Apr 2026 15:16:52 +0200 Subject: [PATCH 049/291] Introduce LLMClientApp type to remove xcode from MCP API swagger enum (#5081) Xcode (GitHub Copilot for Xcode) supports LLM gateway but not MCP client registration. Previously declared as a ClientApp constant, it was included in the generated swagger enum for the MCP API, misleading consumers into attempting unsupported operations. Introduce a separate LLMClientApp type for LLM-gateway-only tools and move the Xcode constant to it. The internal clientAppConfig entry uses an explicit ClientApp(Xcode) cast so the config table continues to work unchanged. Regenerate swagger docs to confirm xcode no longer appears in the enum.

This produced false positives when directories like ~/.claude or ~/.gemini were left over from a prior uninstall or created by unrelated tooling. Add an optional LLMBinaryName field to clientAppConfig. When set, DetectedLLMGatewayClients() now requires both the settings directory and the binary on $PATH (via exec.LookPath) before considering a tool installed. Tools not on $PATH (e.g. Xcode, a macOS GUI app) leave the field empty and fall back to the directory-only check. Populate LLMBinaryName for claude-code ("claude"), gemini-cli ("gemini"), cursor ("cursor"), vscode ("code"), and vscode-insider ("code").

Add the full vMCP-side AWS STS auth path: - AwsStsConverter in the converter registry translates CRD configs to BackendAuthStrategy at session discovery time - AwsStsStrategy performs STS AssumeRoleWithWebIdentity + SigV4 signing with a per-config cache (map + sync.RWMutex, SHA-256 keyed) matching the TokenExchangeStrategy lifecycle - TokenProviderName field on AWSStsConfig enables upstream token selection when an embedded auth server is present on a vMCP (proxy runner and remote proxy are unaffected — upstream swap middleware already handles this); the vMCP controller auto-populates it with the first configured upstream provider when left empty - Export ExtractSessionName from pkg/auth/awssts to eliminate duplication between the middleware and strategy - Validator, yaml_loader, and factory registration all updated - Deep copy, CRD manifests, and API docs regenerated Closes #5018 Co-Authored-By: Claude Sonnet 4.6 * Address review feedback for AwsStsStrategy - Thread caller's context through getOrCreateContext instead of using context.Background, so cancellation propagates to NewExchanger - Add null byte delimiters between fields in buildAwsStsCacheKey to prevent field-separator ambiguity - Cache RequestSigner and sessionDuration in awsStsContext alongside roleMapper and exchanger; remove per-request signer allocation - Call ValidateConfig on cache miss in getOrCreateContext so Authenticate without prior Validate still gets a clear error - Add aws_sts test cases to TestInjectSubjectProviderIfNeeded covering auto-population, already-set not overridden, and nil AwsSts config Co-Authored-By: Claude Sonnet 4.6 * Run `task docs` Co-Authored-By: Claude Opus 4.6 (1M context) * Address review feedback for AwsStsStrategy - Rename TokenProviderName to SubjectProviderName on AWSStsConfig and the runtime AwsStsConfig so it matches token_exchange's name for the same concept (which upstream provider's token to pull from Identity.UpstreamTokens). Aligns the CRD surface across strategies. - In the bearer-token fallback, use identity.Token instead of reading the outgoing request's Authorization header. The outgoing request is the one being constructed for the backend and is not guaranteed to carry the caller's header; identity.Token is the original incoming bearer captured by the auth middleware. Mirrors token_exchange. - Log a debug line when falling back to identity.Token. - Replace sort.Slice with slices.SortStableFunc in buildAwsStsCacheKey so mappings sharing a RoleArn but differing in Claim or Matcher keep their input order. Otherwise logically identical configs could hash to different keys and cause spurious cache misses. - Include cfg.GetSessionDuration() in the cache key. SessionDuration is baked into the cached awsStsContext, so omitting it would let two backends differing only in session duration share a cache entry and silently use the wrong value. - Add a success-path case to TestAwsStsStrategy_Validate. NewExchanger uses aws.AnonymousCredentials{} so it makes no network calls, and the previous test set had only error cases. - Change authtypes.RoleMapping.Priority from *int32 to *int so it actually mirrors awssts.RoleMapping.Priority (the role mapper uses math.MaxInt for nil-priority semantics in effectivePriority). Move the int32->int conversion to the CRD-to-runtime converter, where it belongs. Co-Authored-By: Claude Opus 4.7 (1M context) * Cover aws_sts in outgoing auth registry tests Add authtypes.StrategyTypeAwsSts to the strategy enumeration in both the registration check and the name-mapping table inside TestNewOutgoingAuthRegistry. The factory has registered five strategies since aws_sts was added, but the test only enumerated four — a regression that dropped aws_sts registration would have gone unnoticed.

thv llm setup now accepts inline --gateway-url / --issuer / --client-id (and the other config flags) so "config set" and "setup" can be combined in a single command. Flags are merged into the persisted config before the rest of setup runs. - setup triggers an interactive OIDC browser login after configuring all detected tools, so the refresh token is stored before any tool or proxy tries to use it. - setup starts the localhost proxy as a background process when any proxy-mode tool (Cursor, VS Code, Xcode) was configured, and saves the PID to config so teardown can stop it. - teardown sends SIGINT to the stored proxy PID (if any) before clearing the PID from config. The PID is always zeroed in the final UpdateConfig call regardless of whether the signal succeeded. - pkg/llm.ProxyConfig gains a PID field (yaml/json: "pid") to hold the background proxy process ID across CLI invocations. E2E tests in cli_llm_setup_test.go cover: inline-flag config + tool patching, full teardown revert, single-tool targeted teardown, no-config error, and --purge-tokens token cleanup. Fixes #5031 * thv llm: complete setup/teardown orchestration - setup accepts inline --gateway-url / --issuer / --client-id (and the other config flags), merged into persisted config before running, so config-set and setup can be combined in a single invocation - OIDC browser login runs after tool config files are patched so the refresh token is cached before tools use it; proxy-mode tools receive a hint to run "thv llm proxy start" (foreground command, no daemon) - teardown reverts all (or a single named) tool config patches; --purge-tokens deletes cached OIDC tokens from the secrets provider - loginFunc injected into runLLMSetup for keyring-free unit tests - purgeCachedTokens and hasProxyMode extracted as helpers Fixes #5031 * fixes from review --------- Co-authored-by: taskbot --- cmd/thv/app/llm.go | 138 +++++++++--- cmd/thv/app/llm_test.go | 64 +++++- test/e2e/cli_llm_setup_test.go | 398 +++++++++++++++++++++++++++++++++ test/e2e/oidc_mock.go | 13 +- 4 files changed, 575 insertions(+), 38 deletions(-) create mode 100644 test/e2e/cli_llm_setup_test.go diff --git a/cmd/thv/app/llm.go b/cmd/thv/app/llm.go index 29e5ac0e0c..103c21270a 100644 --- a/cmd/thv/app/llm.go +++ b/cmd/thv/app/llm.go @@ -97,8 +97,8 @@ Example: cmd.Flags().StringVar(&opts.Issuer, "issuer", "", "OIDC issuer URL") cmd.Flags().StringVar(&opts.ClientID, "client-id", "", "OIDC client ID") cmd.Flags().StringVar(&opts.Audience, "audience", "", "OIDC audience (optional)") - cmd.Flags().IntVar(&opts.ProxyPort, "proxy-port", 0, "Localhost proxy listen port (default 14000)") - cmd.Flags().IntVar(&opts.CallbackPort, "callback-port", 0, "OIDC callback port (default: ephemeral)") + cmd.Flags().IntVar(&opts.ProxyPort, "proxy-port", 0, "Localhost proxy listen port (omit to keep current; default: 14000)") + cmd.Flags().IntVar(&opts.CallbackPort, "callback-port", 0, "OIDC callback port (omit to keep current; default: ephemeral)") return cmd } @@ -141,15 +141,7 @@ func newConfigResetCommand() *cobra.Command { tokens from the secrets provider.`, Args: cobra.NoArgs, RunE: func(cmd *cobra.Command, _ []string) error { - // Delete cached tokens from the secrets provider first. - provider, err := secrets.GetSystemSecretsProvider() - if err != nil { - // Non-fatal: log and continue so the config is still cleared. - fmt.Fprintf(os.Stderr, "Warning: could not get secrets provider: %v\n", err) - } else if err := llm.DeleteCachedTokens(cmd.Context(), provider); err != nil { - fmt.Fprintf(os.Stderr, "Warning: could not remove cached LLM tokens: %v\n", err) - } - + purgeCachedTokens(cmd.Context(), cmd.ErrOrStderr()) return config.UpdateConfig(func(c *config.Config) error { c.LLM = llm.Config{} return nil @@ -209,7 +201,9 @@ func buildLLMTokenSource(cfg *llm.Config, interactive bool) (*llm.TokenSource, e // ── setup / teardown ───────────────────────────────────────────────────────── func newLLMSetupCommand() *cobra.Command { - return &cobra.Command{ + var opts llm.SetOptions + + cmd := &cobra.Command{ Use: "setup", Short: "Configure all detected AI tools to use the LLM gateway", Long: `Detect installed AI coding tools (Claude Code, Gemini CLI, Cursor, VS Code, @@ -221,6 +215,10 @@ Token-helper tools (Claude Code, Gemini CLI) are configured to call Proxy-mode tools (Cursor, VS Code, Xcode) are configured to send requests to the localhost reverse proxy started by "thv llm proxy start". +Inline flags (--gateway-url, --issuer, --client-id, etc.) are applied for this +run and persisted to config only after login and tool patching succeed.

REGISTRY.md was still documenting the typed sources[] / git / configMapRef / api / filter / syncPolicy fields directly under spec, which no longer exist on the CRD. - Rewrite Quick Start to use a minimal Kubernetes source via configYAML. - Add a Spec Reference table covering the actual CRD fields and a brief description of what lives inside configYAML. - Restructure Data Sources into Kubernetes / ConfigMap+file / Git / API subsections, each with a configYAML example. Move Git private-repo auth onto passwordFile + volumes/volumeMounts. - Add a PostgreSQL Authentication section covering pgpassSecretRef. - Update Filtering, Sync Operations, and Secret Management to reflect the configYAML path. - Replace the four legacy Examples blocks with a table linking to the canonical examples in examples/operator/mcp-registries/, and fix the See Also link to the renamed git-auth example.

Users configuring private-registry credentials silently got no effect: the proxy-runner Deployment and ServiceAccount were created with no image pull secrets and image pulls failed against authenticated registries. Mirror the MCPServer wiring: extract ImagePullSecrets from ResourceOverrides via a small helper and apply it to both the proxy-runner ServiceAccount (through rbac.EnsureRBACResourcesParams) and the Deployment pod spec.

Anything else the user put on spec.podTemplateSpec.spec -- imagePullSecrets, additional volumes, priorityClassName, topologySpreadConstraints, runtimeClassName, init containers, sidecars -- was silently dropped. Replace the enumerated copy with a strategic merge patch on the raw user JSON (mirroring VirtualMCPServer's approach). The patch preserves every user-provided PodSpec field while controller defaults remain where the user did not set a value. Using the raw JSON avoids the nil-slice-becomes-empty-array problem that re-marshaling would hit. Add a regression test covering imagePullSecrets, priorityClassName, volumes, runtimeClassName, topologySpreadConstraints, and sidecar containers, asserting they all reach the resulting StatefulSet pod template. Fixes #5100 * Skip PodTemplateSpec merge on invalid user input Refusing to build the StatefulSet when the user-provided PodTemplateSpec is malformed left the EmbeddingServer stuck with no pod and broke the existing integration test that asserts a StatefulSet is still created in this case. The validation status condition (Phase=Failed, ConditionPodTemplateValid=False) is the user-facing signal for invalid input; the controller now treats merge failures as soft skips so the resource still produces an observable StatefulSet built from controller defaults. Restores the pre-existing tolerant behavior that the previous field-by-field merge had implicitly via NewPodTemplateSpecBuilder's silent error path. * Extract PodTemplateSpec strategic merge patch to controllerutil The marshal-then-StrategicMergePatch-then-unmarshal sequence was copy-pasted across the EmbeddingServer and VirtualMCPServer controllers. Pull it out into a single policy-neutral helper — `ctrlutil.ApplyPodTemplateSpecPatch` — and have both callers consume it. The helper deliberately does not pick an error policy. Each caller keeps its own: - VirtualMCPServer hard-fails: a patch error blocks Deployment creation, surfaced as a controller error. - EmbeddingServer soft-fails: a patch error is logged and the StatefulSet falls back to controller defaults; the user-facing signal is the existing PodTemplateValid=False status condition. Both behaviors are valid for their respective resources and changing either is out of scope for the EmbeddingServer fix in #5100. The helper's godoc documents the contract; each call site documents which side it picked and why. Drop the now-unused `*EmbeddingServer` parameter from `buildPodTemplate`. Its callers no longer reference it after the merge function was inlined into the patch step in the parent commit. Add unit tests for the helper covering the no-op, merge, and failure cases. Add two new integration-style tests on the EmbeddingServer controller: one for the soft-fail fallback (a payload that the builder accepts but StrategicMergePatch rejects) and one for the empty-object no-op (verifying controller defaults are preserved). * Test by-name merge into the embedding container Strategic merge patch merges containers by name. A user-supplied container called `embedding` is a separate code path from a sidecar with a different name: env and volumeMounts get merged *into* the controller's container rather than appended as a new entry. The existing sidecar test only covered the additive case. Add a regression case that supplies env and volumeMounts on a container named `embedding` and asserts both are present on the single resulting container, and that the controller-set image survives the by-name merge. --- .../controllers/embeddingserver_controller.go | 122 +++--- .../embeddingserver_controller_test.go | 379 ++++++++++++++++++ .../virtualmcpserver_deployment.go | 30 +- .../controllerutil/podtemplatespec_patch.go | 68 ++++ .../podtemplatespec_patch_test.go | 103 +++++ 5 files changed, 621 insertions(+), 81 deletions(-) create mode 100644 cmd/thv-operator/pkg/controllerutil/podtemplatespec_patch.go create mode 100644 cmd/thv-operator/pkg/controllerutil/podtemplatespec_patch_test.go diff --git a/cmd/thv-operator/controllers/embeddingserver_controller.go b/cmd/thv-operator/controllers/embeddingserver_controller.go index 79a4542cf7..70e55668b2 100644 --- a/cmd/thv-operator/controllers/embeddingserver_controller.go +++ b/cmd/thv-operator/controllers/embeddingserver_controller.go @@ -396,7 +396,7 @@ func (r *EmbeddingServerReconciler) validateAndUpdatePodTemplateStatus( // statefulSetForEmbedding creates a StatefulSet for the embedding server func (r *EmbeddingServerReconciler) statefulSetForEmbedding( - _ context.Context, + ctx context.Context, embedding *mcpv1beta1.EmbeddingServer, ) *appsv1.StatefulSet { replicas := embedding.GetReplicas() @@ -406,7 +406,7 @@ func (r *EmbeddingServerReconciler) statefulSetForEmbedding( container := r.buildEmbeddingContainer(embedding) // Build pod template - podTemplate := r.buildPodTemplate(embedding, labels, container) + podTemplate := r.buildPodTemplate(labels, container) // Apply statefulset overrides stsAnnotations, stsLabels := r.applyStatefulSetOverrides(embedding, &podTemplate) @@ -438,6 +438,13 @@ func (r *EmbeddingServerReconciler) statefulSetForEmbedding( statefulSet.Spec.VolumeClaimTemplates = r.buildVolumeClaimTemplates(embedding) } + // Apply user-provided PodTemplateSpec customizations via strategic merge patch. + // This must happen after the controller-generated template is fully populated so + // that user fields override controller defaults rather than the other way around. + // The merge is soft-fail: invalid input is logged and the StatefulSet is built + // from controller defaults.

That works but is undiscoverable in the CRD schema and inconsistent with MCPServer, which has spec.resourceOverrides.proxyDeployment.imagePullSecrets. This adds spec.imagePullSecrets directly to VirtualMCPServerSpec rather than introducing a nested ResourceOverrides struct, since this is the only override field today and adding scaffolding for future fields that may not arrive is speculative. The field is a []corev1.LocalObjectReference and propagates to: - the vMCP Deployment's PodSpec.ImagePullSecrets - the operator-managed ServiceAccount the vMCP server runs as When both spec.imagePullSecrets and spec.podTemplateSpec.spec.imagePullSecrets are set, the existing strategic merge patch handles overlap natively via the corev1.PodSpec.ImagePullSecrets patchStrategy:"merge"+patchMergeKey:"name". Distinct names are unioned; same names get the PodTemplateSpec entry (user override wins on overlap). The ServiceAccount is always populated from spec.imagePullSecrets — PodTemplateSpec has no notion of a ServiceAccount. The legacy podTemplateSpec workaround keeps working unchanged. Part of #5101 Co-Authored-By: Claude Opus 4.7 (1M context) * Detect spec.imagePullSecrets drift on existing Deployment The drift-detection chain compared individual container fields, pod template metadata, and the user-provided podTemplateSpec hash, but never the deployed PodSpec.ImagePullSecrets. A user who edited spec.imagePullSecrets on an existing CR saw no rollout — the Deployment kept stale or missing image pull credentials. Direct equality on deployment.Spec.Template.Spec.ImagePullSecrets is not safe: the live list is the strategic-merge union of spec.imagePullSecrets and any imagePullSecrets the user added under spec.podTemplateSpec.spec.imagePullSecrets, so a direct compare would either flag spurious drift or miss real changes depending on PodTemplateSpec content. Mirror the existing podTemplateSpec hash pattern: store a SHA256 of vmcp.Spec.ImagePullSecrets as a deployment annotation and compare in deploymentNeedsUpdate. The hash normalizes by sorting on Name so a reorder is not treated as drift. PodTemplateSpec drift remains covered by podTemplateSpecNeedsUpdate, so together the two annotations cover every input that influences PodSpec.ImagePullSecrets. Co-Authored-By: Claude Opus 4.7 (1M context) * Document strategic-merge semantics on vmcp imagePullSecrets Strengthen the godoc on VirtualMCPServerSpec.ImagePullSecrets to spell out the strategic-merge-by-name behavior with PodTemplateSpec, the fact that the operator-managed ServiceAccount only sees this field (not the union with PodTemplateSpec), and the current divergence from MCPRegistry's atomic-replace strategy. Tracked for alignment in #5111. Regenerate CRD manifests and crd-api.md to pick up the longer description. Co-Authored-By: Claude Opus 4.7 (1M context) * Add vmcp imagePullSecrets integration tests Cover three flows the unit tests can't reach because they only run the Deployment builder in isolation, not the full reconcile loop: - Create-time propagation: a VirtualMCPServer with spec.imagePullSecrets produces a Deployment whose PodSpec.ImagePullSecrets and a managed ServiceAccount whose ImagePullSecrets both reflect the configured set. - Update-time rollout (regression for the drift-detection fix): editing spec.imagePullSecrets on an existing CR converges the Deployment and SA to the new list. - Combined-source semantics: spec.imagePullSecrets and spec.podTemplateSpec.spec.imagePullSecrets together yield the strategic-merge union on the Deployment, while the SA reflects ONLY spec.imagePullSecrets. Run with envtest (the existing test-integration suite). No new bootstrapping.

union of this field and spec.podTemplateSpec.spec.imagePullSecrets, merged by
the patchStrategy:"merge" / patchMergeKey:"name" tags on corev1.PodSpec.
- This field is rendered first as the controller-generated default.
- spec.podTemplateSpec.spec.imagePullSecrets is then strategic-merge-patched
on top, keyed by Name. Distinct names from the two sources are unioned in
the resulting list; entries with the same Name are deduplicated and the
PodTemplateSpec entry wins on overlap (user override).
- Order in the resulting list is not guaranteed and should not be relied on:
strategic merge by name is order-insensitive.
- The operator-managed ServiceAccount's imagePullSecrets list is populated
ONLY from this field. spec.podTemplateSpec.spec.imagePullSecrets does not
reach the ServiceAccount because PodTemplateSpec has no notion of a
ServiceAccount. To make a secret usable via the ServiceAccount path
(e.g. for sidecars or init containers that pull images independently),
list it here rather than under spec.podTemplateSpec.
Note on cross-CRD consistency:
MCPRegistry currently uses an atomic-replace strategy for its imagePullSecrets
(the user-provided value replaces the controller-generated list rather than
being merged on top). VirtualMCPServer follows the Kubernetes-native
strategic-merge-by-name behavior described above. Aligning the two is tracked
as a separate follow-up; until then, manifests that set imagePullSecrets on
both CRDs will see different override behavior between them. | | Optional: \{\}
| #### api.v1beta1.VirtualMCPServerStatus From e396150da149db37c39842af6d65141e3655c141 Mon Sep 17 00:00:00 2001 From: Juan Antonio Osorio Date: Wed, 29 Apr 2026 12:56:14 +0300 Subject: [PATCH 061/291] Add explicit imagePullSecrets field to MCPRegistry (#5106) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Add explicit imagePullSecrets field to MCPRegistry MCPRegistry workloads previously had no first-class image pull secret field — users had to pass them through the raw-JSON podTemplateSpec escape hatch. That works but is undiscoverable in the CRD schema and inconsistent with MCPServer, which has spec.resourceOverrides.proxyDeployment.imagePullSecrets. This adds spec.imagePullSecrets directly to MCPRegistrySpec rather than introducing a nested ResourceOverrides struct, since this is the only override field today and adding scaffolding for future fields that may not arrive is speculative. The field is a []corev1.LocalObjectReference and propagates to: - the registry-api Deployment's PodSpec.ImagePullSecrets - the operator-managed ServiceAccount the registry API runs as When both spec.imagePullSecrets and spec.podTemplateSpec.spec.imagePullSecrets are set, podTemplateSpec wins on the Deployment (atomic replace); the ServiceAccount always uses spec.imagePullSecrets, since podTemplateSpec has no notion of a ServiceAccount. This matches the existing podTemplateSpec merge semantics. The legacy podTemplateSpec workaround keeps working unchanged. Part of #5101 Co-Authored-By: Claude Opus 4.7 (1M context) * Remove dead dedup loop in WithImagePullSecrets The map-based dedup logic in WithImagePullSecrets was a no-op: the option only ever runs against an empty defaultSpec inside the PodTemplateSpecBuilder, so the "existing" map was always empty. Replace it with a direct assignment now that the merge step in MergePodTemplateSpecs handles user-vs-default precedence atomically. Also rewrite the misleading function comment to match what the code actually does, and document the ImagePullSecrets atomic-replace rule on MergePodTemplateSpecs's godoc bullet list. * Warn about SA-vs-Deployment split brain on imagePullSecrets Strengthen the godoc on MCPRegistrySpec.ImagePullSecrets to call out that this field is the only path that reaches the operator-managed ServiceAccount. The legacy spec.podTemplateSpec.spec.imagePullSecrets populates the Deployment pod spec only and silently bypasses ServiceAccount-level credential injection used by GKE Workload Identity, OpenShift, EKS IRSA, and similar managed platforms. Regenerate CRD manifests and CRD reference docs so the warning lands in the user-facing documentation. * Cover spec.imagePullSecrets in MCPRegistry integration tests Existing integration coverage only exercised the legacy spec.podTemplateSpec.spec.imagePullSecrets path, leaving the new spec.imagePullSecrets field and the ServiceAccount path untested end-to-end. Add four scenarios that go through the controller and a real (envtest) apiserver: - spec.imagePullSecrets only -> Deployment pod spec carries the value - spec.imagePullSecrets only -> ServiceAccount carries the value - spec.imagePullSecrets updated -> both Deployment and SA rotate - spec.imagePullSecrets + podTemplateSpec.imagePullSecrets together -> Deployment uses the PodTemplateSpec override (atomic replacement), SA still tracks spec.imagePullSecrets This locks in the documented merge rule and proves the SA propagation that managed Kubernetes platforms (GKE Workload Identity, OpenShift, EKS IRSA) depend on. * Treat empty imagePullSecrets list as nil to preserve SA defaults When spec.imagePullSecrets is set to an explicit empty slice (kustomize or helm overlays often produce this unintentionally), the RBAC client was wiping the ServiceAccount's existing ImagePullSecrets. On OpenShift this destroys the auto-managed dockercfg entries and breaks private-image pulls in a way that's silent and undiagnosable from the field's docs. Normalize the contract in pkg/kubernetes/rbac so an empty Secrets or ImagePullSecrets slice is treated identically to nil — both leave the existing SA fields untouched. Document the equivalence on MCPRegistrySpec.ImagePullSecrets so users know recreating the resource is the supported way to clear SA-level pull secrets. --------- Co-authored-by: Claude Opus 4.7 (1M context) --- .../api/v1beta1/mcpregistry_types.go | 35 +++ .../api/v1beta1/zz_generated.deepcopy.go | 5 + cmd/thv-operator/pkg/kubernetes/rbac/rbac.go | 25 ++- .../pkg/kubernetes/rbac/rbac_test.go | 54 +++++ .../pkg/registryapi/deployment.go | 1 + .../pkg/registryapi/deployment_test.go | 85 ++++++++ .../pkg/registryapi/podtemplatespec.go | 21 ++ cmd/thv-operator/pkg/registryapi/rbac.go | 11 +- cmd/thv-operator/pkg/registryapi/rbac_test.go | 73 +++++++ .../mcp-registry/deployment_update_test.go | 205 ++++++++++++++++++ .../toolhive.stacklok.dev_mcpregistries.yaml | 100 +++++++++ .../toolhive.stacklok.dev_mcpregistries.yaml | 100 +++++++++ docs/operator/crd-api.md | 1 + 13 files changed, 704 insertions(+), 12 deletions(-) diff --git a/cmd/thv-operator/api/v1beta1/mcpregistry_types.go b/cmd/thv-operator/api/v1beta1/mcpregistry_types.go index a95fd5a775..fd4e8d01aa 100644 --- a/cmd/thv-operator/api/v1beta1/mcpregistry_types.go +++ b/cmd/thv-operator/api/v1beta1/mcpregistry_types.go @@ -109,6 +109,41 @@ type MCPRegistrySpec struct { // +kubebuilder:pruning:PreserveUnknownFields // +kubebuilder:validation:Type=object PodTemplateSpec *runtime.RawExtension `json:"podTemplateSpec,omitempty"` + + // ImagePullSecrets allows specifying image pull secrets for the registry API workload. + // These are applied to both the registry-api Deployment's PodSpec.ImagePullSecrets + // and to the operator-managed ServiceAccount the registry API runs as, so private + // images are pullable through either path. + // + // Use this field for new manifests. + // + // Important: this is the ONLY way to attach image-pull credentials to the + // operator-managed ServiceAccount.

Why this is a dedicated field instead of a regular volume/volumeMount:
PostgreSQL's libpq rejects pgpass files that aren't mode 0600. Kubernetes
secret volumes mount files as root-owned, and the registry-api container
runs as non-root (UID 65532). A root-owned 0600 file is unreadable by
UID 65532, and using fsGroup changes permissions to 0640 which libpq also
rejects. The only solution is an init container that copies the file to an
emptyDir as the app user and runs chmod 0600. This cannot be expressed
through volumes/volumeMounts alone -- it requires an init container, two
extra volumes (secret + emptyDir), a subPath mount, and an environment
variable, all wired together correctly.
When specified, the operator generates all of that plumbing invisibly.
The user creates the Secret with pgpass-formatted content; the operator
handles only the Kubernetes permission mechanics.
Example Secret:
apiVersion: v1
kind: Secret
metadata:
name: my-pgpass
stringData:
.pgpass: \|
postgres:5432:registry:db_app:mypassword
postgres:5432:registry:db_migrator:otherpassword
Then reference it:

| | `podTemplateSpec` _[RawExtension](https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.27/#rawextension-runtime-pkg)_ | PodTemplateSpec defines the pod template to use for the registry API server.
This allows for customizing the pod configuration beyond what is provided by the other fields.
Note that to modify the specific container the registry API server runs in, you must specify
the `registry-api` container name in the PodTemplateSpec.
This field accepts a PodTemplateSpec object as JSON/YAML. | | Type: object
Optional: \{\}
| +| `imagePullSecrets` _[LocalObjectReference](https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.27/#localobjectreference-v1-core) array_ | ImagePullSecrets allows specifying image pull secrets for the registry API workload.
These are applied to both the registry-api Deployment's PodSpec.ImagePullSecrets
and to the operator-managed ServiceAccount the registry API runs as, so private
images are pullable through either path.
Use this field for new manifests.
Important: this is the ONLY way to attach image-pull credentials to the
operator-managed ServiceAccount. The legacy
spec.podTemplateSpec.spec.imagePullSecrets path populates the Deployment's pod
spec ONLY — it does NOT touch the ServiceAccount. On managed Kubernetes
platforms that rely on ServiceAccount-level credential injection (for example
GKE Workload Identity, OpenShift's per-SA dockercfg secrets, EKS IRSA), using
only the legacy PodTemplateSpec path can fail to pull private images even when
the secret exists in the namespace. Always set spec.imagePullSecrets when
SA-level credentials matter.
Precedence with PodTemplateSpec:
- This field is applied first as the controller-generated default.
- Values set under spec.podTemplateSpec.spec.imagePullSecrets are user overrides
and win on overlap. If the user supplies imagePullSecrets via PodTemplateSpec,
those replace the default list on the Deployment (the list is treated atomically).
- The ServiceAccount is always populated from this field — PodTemplateSpec does not
affect the ServiceAccount.
An omitted field and an explicitly empty list are equivalent: both leave the
ServiceAccount's existing ImagePullSecrets unchanged. This preserves
platform-managed pull secrets (for example OpenShift's per-SA dockercfg
entries) when overlays or patches emit an empty list. Truly clearing the
ServiceAccount's pull secrets requires recreating the resource. | | Optional: \{\}

Per cli-commands.md the CLI layer should be a thin wrapper. Move Setup, Teardown, LoginFunc, mergeToolConfigs, hasProxyMode, isTarget, and PurgeTokens to pkg/llm/setup.go. Introduce GatewayManager and ConfigUpdater interfaces so pkg/llm does not need to import pkg/client or pkg/config (which both transitively import pkg/llm). CLI adapters in cmd/thv/app/llm.go bridge the concrete types to these interfaces.

As a result, editing the field on a live CR did not roll the existing Deployment: the proxy- runner ServiceAccount was refreshed via EnsureRBACResources (so kubelet recovered for new pods through the SA path), but the pod-spec field on the live Deployment remained stale. In the user-managed- ServiceAccount branch, where RBAC reconciliation is skipped, the pod- spec field is the only mechanism — so that path stayed broken. Add a comparison in both controllers using equality.Semantic.DeepEqual so nil and empty slices are treated identically (matching Kubernetes' own serialization semantics) and reorder/add/remove on populated slices triggers a rollout. MCPRemoteProxy gets a new podSpecNeedsUpdate sub-helper alongside the existing containerNeedsUpdate / deploymentMetadataNeedsUpdate / podTemplateMetadataNeedsUpdate trio; MCPServer gets an inline check that mirrors the surrounding style of its single deploymentNeedsUpdate function. Each controller gets a table-driven unit test covering seven cases: the no-override baseline, the bug repro, the removal flow, the populated match, the nil-vs-empty asymmetry from both sides, and the slice-reorder case (which equality.Semantic.DeepEqual treats as drift). Two envtest integration tests per controller exercise the full reconcile-update path: create CR, assert Deployment, mutate imagePullSecrets, assert Deployment rolls.

charset=UTF-8 Content-Transfer-Encoding: 8bit * Add operator-level defaultImagePullSecrets plumbing Cluster operators frequently need a registry pull secret applied to every workload the operator spawns (proxy runners, registry API, vMCP servers, embedding servers). Today the chart only exposes imagePullSecrets for the operator's own pod, forcing users to set the secret on every CR or to mutate the namespace-default ServiceAccount. This change introduces a chart value, operator.defaultImagePullSecrets, that the operator picks up at startup via THV_DEFAULT_IMAGE_PULL_SECRETS and applies as a default to every workload it spawns. All five workload-spawning reconcilers consume the shared imagepullsecrets.Defaults value and merge it with the per-CR list at workload-construction time: MCPServer, MCPRemoteProxy, MCPRegistry (via registryapi.manager), VirtualMCPServer, and EmbeddingServer. Precedence rule: per-CR imagePullSecrets take priority on name collisions; chart-level entries are appended additively and deduped by Name. The CR-level slice is never mutated. EmbeddingServer places the chart defaults on the base PodSpec and lets strategic-merge-patch additively union the user's PodTemplateSpec entries (PodSpec.ImagePullSecrets is declared with patchStrategy:"merge",patchMergeKey:"name"). Drift detection on every controller routes through the same merge helper as the construction site so chart defaults do not flag perpetual reconcile loops. The Helm template renders operator.env before chart-managed env vars so a user-supplied entry cannot silently override a reserved name like THV_DEFAULT_IMAGE_PULL_SECRETS — Kubernetes keeps the last entry on a duplicate-named env. The startup parser logs a diagnostic when the env var is set but parses to nothing (typos like " , " or ",,,") so the misconfiguration is visible. Part of #5102 Co-Authored-By: Claude Opus 4.7 (1M context) * Address review: TOOLHIVE_ env var prefix and accept both shapes Rename THV_DEFAULT_IMAGE_PULL_SECRETS to TOOLHIVE_DEFAULT_IMAGE_PULL_SECRETS to match the operator container's TOOLHIVE_* convention before the env var ships and a rename costs a deprecation cycle. Accept both shapes in operator.defaultImagePullSecrets to mirror operator.imagePullSecrets above: - plain strings: ["regcred", "otherscred"] - object with `name`: [{name: regcred}, {name: otherscred}] Users who copy the [{name: foo}] pattern from operator.imagePullSecrets no longer get a silent THV_DEFAULT_IMAGE_PULL_SECRETS=map[name:foo] env var and ImagePullBackOff at runtime. Malformed entries (numbers, nested lists, objects without a `name` field) now fail the helm template render with a clear message instead of producing a bogus env var. --------- Co-authored-by: Claude Opus 4.7 (1M context) --- .../controllers/embeddingserver_controller.go | 18 +- ...ingserver_default_imagepullsecrets_test.go | 72 +++++ .../controllers/mcpregistry_controller.go | 14 +- .../controllers/mcpremoteproxy_controller.go | 35 ++- ...moteproxy_default_imagepullsecrets_test.go | 110 ++++++++ .../controllers/mcpremoteproxy_deployment.go | 2 +- .../controllers/mcpserver_controller.go | 53 ++-- ...mcpserver_default_imagepullsecrets_test.go | 168 +++++++++++ .../virtualmcpserver_controller.go | 44 ++- ...mcpserver_default_imagepullsecrets_test.go | 129 +++++++++ .../virtualmcpserver_deployment.go | 33 ++- cmd/thv-operator/main.go | 94 +++++-- .../pkg/imagepullsecrets/defaults.go | 121 ++++++++ .../pkg/imagepullsecrets/defaults_test.go | 264 ++++++++++++++++++ .../pkg/registryapi/deployment.go | 4 +- cmd/thv-operator/pkg/registryapi/manager.go | 18 +- .../pkg/registryapi/manager_test.go | 7 +- cmd/thv-operator/pkg/registryapi/rbac.go | 2 +- .../mcp-registry/suite_test.go | 5 +- deploy/charts/operator/README.md | 3 +- .../charts/operator/templates/deployment.yaml | 38 ++- deploy/charts/operator/values.yaml | 16 ++ 22 files changed, 1147 insertions(+), 103 deletions(-) create mode 100644 cmd/thv-operator/controllers/embeddingserver_default_imagepullsecrets_test.go create mode 100644 cmd/thv-operator/controllers/mcpremoteproxy_default_imagepullsecrets_test.go create mode 100644 cmd/thv-operator/controllers/mcpserver_default_imagepullsecrets_test.go create mode 100644 cmd/thv-operator/controllers/virtualmcpserver_default_imagepullsecrets_test.go create mode 100644 cmd/thv-operator/pkg/imagepullsecrets/defaults.go create mode 100644 cmd/thv-operator/pkg/imagepullsecrets/defaults_test.go diff --git a/cmd/thv-operator/controllers/embeddingserver_controller.go b/cmd/thv-operator/controllers/embeddingserver_controller.go index 70e55668b2..8149ad9d85 100644 --- a/cmd/thv-operator/controllers/embeddingserver_controller.go +++ b/cmd/thv-operator/controllers/embeddingserver_controller.go @@ -29,6 +29,7 @@ import ( mcpv1beta1 "github.com/stacklok/toolhive/cmd/thv-operator/api/v1beta1" ctrlutil "github.com/stacklok/toolhive/cmd/thv-operator/pkg/controllerutil" + "github.com/stacklok/toolhive/cmd/thv-operator/pkg/imagepullsecrets" ) // EmbeddingServerReconciler reconciles a EmbeddingServer object @@ -37,6 +38,13 @@ type EmbeddingServerReconciler struct { Scheme *runtime.Scheme Recorder events.EventRecorder PlatformDetector *ctrlutil.SharedPlatformDetector + // ImagePullSecretsDefaults are cluster-wide defaults sourced from the + // operator chart, applied to the StatefulSet's PodSpec before the + // user-provided PodTemplateSpec strategic-merge patch runs.

When a provider omits it, the client has no basis to invent an expiry. Slack user tokens and GitHub OAuth App tokens deliberately omit expires_in because they are genuinely non-expiring and have no refresh token. The fabricated 1h ExpiresAt caused guaranteed hourly re-authorization failures for those providers: the token appeared expired, a refresh was attempted with no refresh token, ErrNoRefreshToken was returned, and the token was dropped from the service. Remove defaultTokenExpiration and the fabrication block. Pass token.Expiry (the Go zero value when expires_in is absent) through directly so downstream code sees zero ExpiresAt and treats the token as non-expiring. Guard the expires_at log field to emit "none" instead of the misleading year-0001 timestamp. Fixes #5046 Co-Authored-By: Claude Sonnet 4.6 * Fix zero-ExpiresAt semantics in IsExpired/IsExpiredAt Both methods returned true for a zero ExpiresAt value because now.After(time.Time{}) is always true (year 1 is in the past). All production call sites guarded with !ExpiresAt.IsZero() before calling, so the bug was harmless, but the methods were latent traps for future callers. Embed the zero guard inside each method: zero ExpiresAt means the provider did not assert an expiry, so the token is treated as non-expiring. Add nil-receiver guards for consistency and defensive correctness. Co-Authored-By: Claude Sonnet 4.6 * Fix storage backends to not evict non-expiring tokens Both backends applied a default ~31-day TTL when ExpiresAt was zero, which would silently evict non-expiring tokens and prevent retrieval. memory.go: split StoreUpstreamTokens logic so zero ExpiresAt leaves the timedEntry expiry as the zero value (never evicted). Guard cleanupExpired to skip entries with a zero expiry. redis.go: initialise ttl to zero in marshalUpstreamTokensWithTTL and only set it for non-zero ExpiresAt. The Lua script already handles ttl=0 by calling SET without PX. Add PERSIST on the session index set when ttl=0 so a non-expiring token write removes any TTL a prior expiring-token write set on the index set, preventing the index from being evicted while the non-expiring token still exists. Co-Authored-By: Claude Sonnet 4.6 * Add regression test for non-expiring upstream token handling Verifies that GetValidTokens returns a stored token with zero ExpiresAt unchanged and does not attempt a refresh. The failure signal is structural: no mockoidc user is queued, so any refresh attempt would cause the test to fail via a mockoidc error. Co-Authored-By: Claude Sonnet 4.6 * Bound non-expiring upstream token storage to Fosite session lifetime Non-expiring upstream tokens (zero ExpiresAt — providers that omit expires_in) previously had no storage TTL, so they were never evicted by the cleanup loop. The only removal path was explicit deletion, which only happened on authorization error paths. Add SessionExpiresAt to UpstreamTokens. The callback handler sets it to the Fosite refresh token expiry; the refresher carries it forward on token rotation. Both MemoryStorage and RedisStorage use it as a fallback TTL when ExpiresAt is zero, ensuring non-expiring upstream tokens are evicted when the session would have expired. Tokens where both ExpiresAt and SessionExpiresAt are zero remain indefinitely stored — the existing behaviour for cases where the session expiry is unknown. Co-Authored-By: Claude Sonnet 4.6 * Always set SessionExpiresAt to bound refreshed non-expiring tokens Previously SessionExpiresAt was only set in the callback when idpTokens.ExpiresAt was zero. This created a hole in the refresh path: if the initial callback got a token with non-zero ExpiresAt, the stored SessionExpiresAt remained zero. If a later refresh response omitted expires_in, the refresher carried the (zero) SessionExpiresAt forward, the new row had both ExpiresAt and SessionExpiresAt zero, and storage backends stored it without any TTL — leaking indefinitely. Make SessionExpiresAt unconditionally meaningful: set it on every callback as the Fosite session bound. Storage backends still only consult it as a fallback when ExpiresAt is zero, so behaviour for expiring tokens is unchanged. The refresh path is now safe even if a provider stops asserting expires_in on a later rotation. Add TestUpstreamTokenRefresher_PreservesSessionExpiresAt to lock down that the refresher carries SessionExpiresAt forward into the updated record — easy regression for future refactors. Co-Authored-By: Claude Sonnet 4.6 * Fix Lua TTL inversion that orphaned mixed-expiry session indexes The session-index set in Redis must outlive every per-provider key it points to. The previous logic conflated "fresh set just SADD'd" with "existing set previously PERSIST'd by a non-expiring member" because PTTL returns -1 in both cases. The condition `currentTTL < ttlMs` was therefore always true for -1, causing PEXPIRE to undo a prior PERSIST. Failure mode: store a non-expiring token (PERSIST'd index), then store an expiring token for the same session — the index re-acquired a TTL, evicted at the expiring token's expiry, and the non-expiring token's per-provider key (which has no TTL) became unreachable through GetAllUpstreamTokens and DeleteUpstreamTokens. This fired deterministically for any multi-upstream chain that had a non-expiring provider followed by an expiring one (e.g., GitHub PAT + Google). Distinguish the two cases by reading EXISTS BEFORE SADD. Pre-SADD existence is unambiguous: if the set didn't exist, our SADD just created it and we own the TTL decision; if it did exist, its current TTL summarises prior members and a -1 means "intentionally persistent, leave alone". Add tests for: - Reverse-order mixed-expiry (non-expiring → expiring) — the bug - Fresh expiring write applies index TTL — regression guard - Same-provider rewrite from non-expiring to expiring — documents the intentional limitation that the index stays PERSIST'd until DeleteUpstreamTokens cleans up Co-Authored-By: Claude Sonnet 4.6 * Guard expires_at log fields against zero-time formatting Commit 824bc552f's body promised "Guard the expires_at log field to emit 'none' instead of the misleading year-0001 timestamp" but only removed .Format(time.RFC3339) — slog still serialises a zero time.Time as "0001-01-01T00:00:00Z". Two log sites in oidc.go (during the authorization-code-exchange and refresh paths) were never touched and still called .Format() unconditionally. Add formatExpiresAt(t time.Time) to the upstream package: returns "none" for zero time, RFC 3339 otherwise. Apply at all four log sites (oauth2.go ×2, oidc.go ×2). Drop the now-unused time import in oidc.go. Co-Authored-By: Claude Sonnet 4.6 * Add integration tests for non-expiring upstream token handling Two end-to-end regressions covering the cascade-prevention fix and the chain handler's per-leg storage write: * TestIntegration_FullFlow_NonExpiringUpstreamToken — drives the full /authorize → /callback → /token flow against a mock OIDC server whose token endpoint has been wrapped to strip expires_in from responses. Asserts the stored token has zero ExpiresAt, GetValidTokens succeeds without triggering a refresh, and post-call ExpiresAt is still zero. Catches regressions that re-introduce a default expiry anywhere in the HTTP-response → convertOAuth2Token → storage path. * TestIntegration_MultiUpstreamChain_MixedExpiryOrderings — table-driven, both orderings of mixed-expiry providers in a two-leg chain. Asserts GetAllValidTokens returns both providers regardless of order. Pins the chain handler's per-leg storage write and the convertOAuth2Token zero-Expiry path through the full HTTP flow. The Redis Lua TTL semantics remain covered by the unit-level tests in pkg/authserver/storage/redis_test.go. Helpers: * captureResponseWriter / stripExpiresInMiddleware — buffer the upstream token response and remove expires_in before forwarding. Lets us drive a non-expiring token response without forking mockoidc. * startMockOIDCNoExpiresIn — applies the strip middleware to a mock OIDC server. Deliberately does NOT queue a default user, so any unintended refresh attempt fails (the failure signal for the cascade-prevention test). * runChainFlow — extracted the two-leg chain navigation from TestIntegration_MultiUpstreamSequentialChain, including the state-preservation invariant. The original test now uses the helper, eliminating duplicated chain-navigation code. Co-Authored-By: Claude Sonnet 4.6 * Add miniredis-backed integration test harness Reusable infrastructure for driving the full /authorize → /callback → /token flow against Redis-shape storage, plus Redis-variant siblings for the two new integration tests added in this branch. The harness: * `withRedisBackedStorage()` functional option on `testServerOptions` * `testServer.Miniredis(t)` accessor that fails loudly if the option wasn't applied (avoids nil-deref foot-gun from a struct field that's only sometimes populated) * The three setup helpers (`setupTestServer`, `setupTestServerWithOIDCProvider`, `setupTestServerWithTwoUpstreams`) gained a variadic `...testServerOption` parameter; default behavior unchanged (memory storage) * Default Redis prefix `test:auth:{ns:test}:` matches production-shape cluster routing semantics (hash tag), even though miniredis ignores slots The Redis-variant tests: * `TestIntegration_FullFlow_NonExpiringUpstreamToken_Redis` — symmetry coverage of the convertOAuth2Token → Redis storage path. Drives the same flow as the memory variant against miniredis. * `TestIntegration_MultiUpstreamChain_MixedExpiryOrderings_Redis` — smoke test for the chain handler ↔ Redis storage path through real Lua execution in both orderings. Note on the Lua TTL inversion bug (commit fec89b040): the integration test intentionally does NOT cover that bug. It only fires when marshalUpstreamTokensWithTTL produces ttlMs == 0, which requires both ExpiresAt and SessionExpiresAt to be zero on the UpstreamTokens. Since callback.go unconditionally sets SessionExpiresAt = now + RefreshTokenLifespan (commit 1b3bc81e2), the integration flow always produces ttlMs > 0 and the buggy Lua branch is unreachable from a real auth chain. The Lua invariant is locked down at unit level by pkg/authserver/storage/redis_test.go, which can construct UpstreamTokens with both zero fields directly. Co-Authored-By: Claude Sonnet 4.6 * Re-anchor SessionExpiresAt on refresh for legacy zero rows The PR's invariant — SessionExpiresAt is set unconditionally on every callback so the refresh path can carry it forward as a storage TTL bound — holds for fresh writes after this PR ships. Pre-PR Redis rows decode SessionExpiresAt as zero because the field was absent from the persisted JSON. If such a legacy row is refreshed and the upstream rotation also drops expires_in, both bounds would be zero. The Redis backend would PERSIST the indexed row and the Memory backend would retain it indefinitely (Redis at least caps blast radius via the legacy 30-day per-key TTL; Memory has no backstop). Defensively re-anchor SessionExpiresAt to now+RefreshTokenLifespan when both bounds on the candidate write would be zero. RefreshTokenLifespan is threaded from the validated Config through the server struct into upstreamTokenRefresher — the same value the callback writer uses, so legacy rows transition into the post-PR invariant on first refresh rather than being persisted unbounded. Co-Authored-By: Claude Sonnet 4.6 * Document same-provider PERSIST rewrite trade-off The Lua script's index-TTL rule "leave a PERSIST'd set alone" is correct for the cross-provider mixed-expiry case but has a known limitation: when the SAME (sessionID, providerName) slot is rewritten from non-expiring to expiring, the index stays PERSIST'd even though the only persistence anchor is gone. Detecting that would require per-member TTL tracking, which we deliberately avoided; the index is reaped on DeleteUpstreamTokens or session GC anyway. The behaviour is pinned by the redis_test.go case "same provider rewrite from non-expiring to expiring keeps PERSIST'd until rewrite", but the production code never said why. A future maintainer tightening the rule would have hit that test failure and had to reverse-engineer the rationale from the test name. Spell out the trade-off next to the invariant so the connection is obvious. Co-Authored-By: Claude Sonnet 4.6 * Pin 1-second TTL clamp for deeply-stale upstream tokens Before the fix on this branch, marshalUpstreamTokensWithTTL fell through to DefaultRefreshTokenTTL (30 days) when time.Until(ExpiresAt) + DefaultRefreshTokenTTL was negative — meaning both the access token and its 30-day refresh grace had elapsed. The same silent over-retention applied to the SessionExpiresAt branch introduced in this series. The fix changed the floor to time.Second so deeply-stale rows evict promptly. Without a regression test, a future refactor could silently revert this clamp — cold-path callers (refresher races, admin rewrites, legacy-row migrations) would then observe a 30-day grace on tokens that should have been evicted, causing unintended token retention in Redis. Add two subtests to TestRedisStorage_UpstreamTokens, one for each branch, that store a token with stalePast = -(DefaultRefreshTokenTTL + 1h) and assert mr.TTL ≤ 2s. Both fail loudly if the clamp is reverted. Co-Authored-By: Claude Sonnet 4.6 * Pin wire-shape contract for legacy upstream token JSON Pre-PR Redis rows have no "session_expires_at" key. The read path correctly handles this via a != 0 sentinel, but nothing in the test suite exercised that path with raw legacy bytes. Without a pinning test, a future refactor — e.g. switching to json.NewDecoder().DisallowUnknownFields() or renaming the JSON tag — would silently break deserialization of existing rows. Add a subtest that hand-rolls a legacy JSON string (no "session_expires_at"), injects it into miniredis directly via mr.Set, calls GetUpstreamTokens, and asserts that all non-time fields round-trip correctly and that SessionExpiresAt.IsZero() is true. Co-Authored-By: Claude Sonnet 4.6 * Fix SessionExpiresAt godoc to mention all write sites The previous comment claimed only the callback handler writes this field, but the refresher also writes it: it carries the value forward unchanged on every refresh, and (after the legacy-row defensive re-anchor) sets it from RefreshTokenLifespan when both bounds are zero on the input. The new test "preserves SessionExpiresAt when provider omits expires_in" (refresher_test.go) and the legacy-row re-anchor case both depend on these behaviors. Documenting them on the field makes the contract discoverable without grepping for write sites. Addresses #5092 review F9.

With UserInfo previously required, the embedded auth server could not integrate any such upstream: token exchange would succeed and then the userinfo step would fail (e.g. 401 against an unrelated identity API), surfacing as ErrIdentityResolutionFailed and aborting the auth flow. Make OAuth2UpstreamConfig.UserInfo optional. When nil, BaseOAuth2Provider.ExchangeCodeForIdentity skips the userinfo call and synthesizes a deterministic, non-PII Subject from a SHA-256 prefix of the access token (35 chars, "tk-" prefix so synthesized subjects are recognizable in logs and JWTs). Name and Email remain empty in this mode. The synthesized subject is stable for the lifetime of the access token and rotates on re-authentication, which is sufficient for the proxy's session-key role. Scoped to OAuth2 only — OIDC providers always have an ID-token- derived subject and never reach this path. Co-Authored-By: Claude Opus 4.7 (1M context) * Bypass UserResolver for synthetic identities Synthesized subjects (set by OAuth2 upstreams whose userInfo is nil) are derived from the access token and rotate on every re-authentication. The previous wiring fed them into UserResolver.ResolveUser, which falls through to createUserWithIdentity whenever (providerID, providerSubject) is unknown — i.e. on every re-auth, since the synthesized subject is never the same twice. For a long-running auth server fronting a synthesis-mode upstream, the `users` and `provider_identities` tables grow without bound and per-user state fragments across many internal IDs that all map back to the same human. Mark synthesized identities with a new Identity.Synthetic flag and have the callback handler use the synthesized Subject directly as an ephemeral session key when the flag is set, skipping both ResolveUser and UpdateLastAuthenticated. UpstreamSubject continues to flow into stored UpstreamTokens, so refresh-token rotation is unaffected (refresher.go already preserves expired.UpstreamSubject). Coverage: TestBaseOAuth2Provider_ExchangeCodeForIdentity asserts the synthesis path sets Synthetic=true; new TestCallbackHandler_SyntheticIdentity_BypassesUserResolver drives the full callback flow with a synthetic Identity and asserts neither the users map nor the provider_identities map gain a row, while upstream tokens still persist and the response still redirects with an authorization code. Addresses PR #5094 review comment. Co-Authored-By: Claude Opus 4.7 (1M context) * Surface synthesis-mode upstreams in operator-visible state Address three PR review comments on the synthesis-mode fallback so a silent regression — operator drops or misnames the userInfo block by typo, stale CRD bundle, or copy-paste — is loud at every visible surface rather than only manifesting later as missing identity claims in proxyrunner audit trails. Per-comment changes: - WARN at provider construction (oauth2.go): NewOAuth2Provider emits a one-shot WARN when UserInfo is nil, calling out that synthesis mode is active and what it does (non-PII subject, no Name/Email). Logs once per provider construction, not per-request, so steady-state is quiet. - Status condition on the owning CRDs (mcpexternalauthconfig_types.go, controllers): new advisory ConditionTypeIdentitySynthesized published by both MCPExternalAuthConfigReconciler and VirtualMCPServerReconciler.validateAuthServerConfig, set True with reason OAuth2UpstreamWithoutUserInfo and the offending upstream names in the message when at least one OAuth2 upstream lacks userInfo, set False (AllUpstreamsHaveUserInfo) when every upstream has one, and removed entirely for non-embeddedAuthServer types or when AuthServer- Config is absent. Source-of-truth helper EmbeddedAuthServerConfig. SyntheticIdentityUpstreams returns the affected upstream names sorted for deterministic messages, so both controllers behave identically per the operator status-condition-parity rule. - Drop decorative userinfo tripwire (oauth2_test.go): the tripwire server's URL was never wired into the OAuth2Config under test, so the zero-hits assertion was vacuously true. Replaced with a comment explaining that the prefix-tagged Subject plus empty Name/Email assertions ARE the observable side-effect of the synthesis branch (the userinfo path populates Name/Email and would never produce a "tk-" subject), so the existing assertions cover the regression class. Coverage: - Unit test for EmbeddedAuthServerConfig.SyntheticIdentityUpstreams covering nil config, OIDC-only (skipped), OAuth2 with userInfo (skipped), single + multiple synthesizing upstreams (sorted), and mixed sets. - Reconciler tests for both MCPExternalAuthConfigReconciler and VirtualMCPServerReconciler.validateAuthServerConfig asserting the IdentitySynthesized condition's status, reason, and that synthesizing upstream names appear in the message — and that the condition is absent for non-embeddedAuthServer types.

Co-Authored-By: Claude Opus 4.7 (1M context) * Refine synthesis-mode contract docs and recognition Address four PR review comments tightening the externally observable contract of synthesis-mode subjects so downstream consumers (audit pipelines, status conditions, debug tooling) can reason about them without hardcoding implementation details, and so the docstrings accurately describe what the algorithm guarantees. - pkg/authserver/upstream/oauth2.go: export IsSynthesizedSubject(string) bool. Recognizing a synthesis-mode subject is part of the package's stable surface (it appears in JWTs, logs, and audit records); a predicate is the supported way for downstream code to detect it without reaching for the literal "tk-". The internal synthesizedSubjectPrefix constant stays unexported — the prefix value is an implementation detail behind the predicate. Doc comment for synthesizeSubjectFromAccessToken now narrows its security claim to what SHA-256 actually guarantees: the digest reveals nothing about the input beyond what an attacker who already has a candidate token could confirm by re-hashing, and the output is non-PII only assuming the upstream issues opaque (non-JWT) tokens. - pkg/authserver/upstream/types.go: rewrite Identity.Subject's doc to enumerate all three sources (OIDC ID-token sub, OAuth2 userinfo sub, OAuth2 synthesized "tk-" value) and add a stability-contract paragraph that distinguishes refresh-token rotation (Subject stable) from a fresh authorization code flow on a synthesis-mode upstream (Subject rotates). The previous one-liner ("the canonical user identifier from the upstream IDP") silently lied about the synthesis branch. - pkg/authserver/config.go: drop the cross-package symbol reference to BaseOAuth2Provider.ExchangeCodeForIdentity in OAuth2UpstreamRunConfig.UserInfo's doc — Go has no compile-time check that prose names exist, so a rename or move silently rots the comment. New wording describes the behavior (SHA-256 + "tk-" prefix, OAuth2-only, OIDC unaffected) directly. - pkg/authserver/upstream/oauth2_test.go: TestIsSynthesizedSubject table covers the round-trip case (any synthesizeSubjectFromAccessToken output is recognized) and false-positive guards (UUIDs, integer IDs, Atlassian-shaped account_ids, empty strings, "tk-" appearing mid-string). Strengthen the existing "empty token" subtest to assert the documented output shape (prefix + 32 hex chars) instead of only determinism — a regression that short-circuited empty input to "" would previously have passed.

The output is opaque: assuming the upstream issues opaque (non-JWT) bearer tokens, the digest reveals nothing about the input that an attacker holding a candidate token could not already confirm by re-hashing. The returned `*Identity` carries `Synthetic = true`; the `upstream.IsSynthesizedSubject(string)` predicate lets bare-string consumers recognize the prefix. + +**`UserResolver` bypass.** Synthetic identities skip `UserResolver.ResolveUser` entirely — no row is created in `UserStorage`, no entry is written to provider-identities, and `UpdateLastAuthenticated` is not called. The synthesized subject rotates per access token, so persisting it would create a fresh `users` row on every re-authentication. `UpstreamTokens.UserID` therefore carries the `tk-…` value directly rather than a stable internal UUID. + +**Reverse-index implication (Redis backend).** The `KeyTypeUserUpstream` secondary-index set under `thv:auth:{ns:name}:user:upstream:{userID}` is designed around stable user IDs — one set per user, holding all of that user's session IDs. Under synthesis the userID rotates with every re-authentication, so each session lands in its own one-element set. Reads continue to work, but set churn is much higher than under OIDC. The existing TODO at `pkg/authserver/storage/redis.go:43-45` to scan and clean up stale secondary-index entries applies, and synthesis-mode workloads make a periodic scan more important. + +**Operator visibility.** When at least one configured OAuth2 upstream has `userInfo == nil`, the controller surfaces the `IdentitySynthesized` condition on the `MCPExternalAuthConfig` and `VirtualMCPServer` status (Reason `IdentitySynthesizedActive`, naming the affected upstreams).

Deployments whose policy vocabulary doesn't use "THVGroup" had no way to switch without patching the authorizer. Add an optional GroupEntityType field to ConfigOptions and thread it through EntityFactory so deployments can use names like OrgRole or Group that fit their policy vocabulary. Empty defaults to "THVGroup" so existing deployments are unaffected. Validate non-empty values up front in NewCedarAuthorizer, per the constructor-validation rule in .claude/rules/go-style.md, so a typo fails at startup with a message naming the offending input rather than producing broken entity lookups at request time. Delegate the identifier-grammar check to cedar-go's policy parser by round-tripping a synthetic permit() against the configured type — Cedar's parser is the source of truth for what a valid identifier looks like, and any future grammar refinements upstream land here automatically. Reject the "::" namespace separator ourselves: namespaced types are out of scope until parseCedarEntityID handles them. Warn at construction when entities_json contains entities of type "THVGroup" while GroupEntityType is configured to a different value. The mismatch causes Cedar's "in" operator to evaluate to false on those stale entities — a silent deny that is hard to debug without this diagnostic.

Purely additive: no behavior change, no CRD changes. - pkg/oauthproto: FetchAuthorizationServerMetadata with three-path RFC 8414 / OIDC Discovery fallback, bounded per-call timeout, RFC 8414 §3.3 issuer equality check, and ErrRegistrationEndpointMissing sentinel. Leaf-package invariant preserved (no pkg/networking import). - pkg/authserver: DCRUpstreamConfig struct plus DCRConfig field on OAuth2UpstreamRunConfig for operators who want runtime RFC 7591 registration instead of a pre-provisioned ClientID. - pkg/authserver: OAuth2UpstreamRunConfig.Validate and DCRUpstreamConfig.Validate enforce exactly-one-of for ClientID vs DCRConfig and DiscoveryURL vs RegistrationEndpoint; CommonOAuthConfig.Validate is unchanged. Address code review feedback on DCR discovery Fixed issues from code review of commit b408d6b2: - HIGH: bare-path discovery test now uses a non-empty tenant path so all three well-known URLs are distinct, proving the third-iteration fallback actually runs. - HIGH: buildDiscoveryURLs deduplicates path-insertion and bare URLs when the issuer has no tenant path, avoiding a redundant round-trip and duplicate entries in the aggregated error. - MEDIUM: deferred body drain no longer wraps resp.Body in io.LimitReader, so large responses are fully drained for connection reuse; the JSON decode path still bounds accepted bytes. - MEDIUM: expanded FetchAuthorizationServerMetadata doc comment with a worked errors.Is example for the (metadata, ErrRegistrationEndpointMissing) return contract; tightened the corresponding test to assert the partial document fields. - MEDIUM: added TestFetchAuthorizationServerMetadata_InvalidIssuer covering empty issuer, malformed URL, missing scheme/host, http non-loopback, and ftp scheme; added TestFetchAuthorizationServerMetadata_AllowsLoopbackHTTP to lock the loopback carve-out. - MEDIUM: added TestFetchAuthorizationServerMetadata_TimeoutOverridesCallerContext that shortens the timeout via a new discoveryTimeout var and asserts the function honors its internal bound even when the caller passes context.Background. - MEDIUM: normalized struct-tag spacing on DCRUpstreamConfig to match the surrounding single-space style; kept //nolint:lll only on fields whose tag line actually exceeds 120 characters. - MEDIUM: replaced the 13-line Apache header with the 2-line SPDX header on pkg/oauthproto/discovery.go, discovery_test.go, and errors.go to match the project convention already used elsewhere in the package. Fix misordered nolint:paralleltest comment on timeout test The comment block above TestFetchAuthorizationServerMetadata_TimeoutOverridesCallerContext split a single sentence across the //nolint directive in the wrong order, so reading top to bottom the explanation appeared before the directive ended mid-phrase. Reword the prose onto three lines above the test and drop a single-line //nolint:paralleltest directive directly above func. - MEDIUM: readability fix only — no behavior, assertions, or public surface changed. Co-Authored-By: Claude Opus 4.7 (1M context) * Address PR #5041 review feedback Wire the new run-config validators into the load path and tighten the discovery fallback so feedback from review #4198420468 stops being a documentation-only promise. - Call OAuth2UpstreamRunConfig.Validate from buildPureOAuth2Config so the ClientID/DCRConfig mutual-exclusion rule actually runs at the RunConfig→upstream-config conversion boundary, not as dead code. - Move OAuth2UpstreamRunConfig.Validate and DCRUpstreamConfig.Validate next to Config.Validate to satisfy the public-methods-on-top rule. - Reject configs that set both InitialAccessTokenFile and InitialAccessTokenEnvVar; the docs already promised mutual exclusion and silent precedence would mask credential rotation. - Validate DiscoveryURL / RegistrationEndpoint via networking.ValidateEndpointURL so malformed or non-loopback-HTTP URLs fail at startup instead of at first DCR call. - Stop short-circuiting in FetchAuthorizationServerMetadata when an issuer-validated document is missing registration_endpoint: stash it and keep iterating so a later URL with a full document wins. Real IdPs sometimes advertise DCR only on the OIDC document. - Aggregate per-attempt discovery errors with errors.Join + %w so callers can still inspect causes through errors.Is / errors.As. - Use parsed.Path instead of parsed.EscapedPath when building discovery URLs so url.URL.String escapes the tenant exactly once; tenants with characters like spaces no longer become "%2520". Tests cover each change, including a regression test that pins the deduplication of path-insertion and bare RFC 8414 URLs for tenant-less issuers. --------- Co-authored-by: Claude Opus 4.7 (1M context) --- docs/server/docs.go | 35 +- docs/server/swagger.json | 35 +- docs/server/swagger.yaml | 53 ++- pkg/authserver/config.go | 133 ++++++ pkg/authserver/config_test.go | 164 +++++++ pkg/authserver/runner/embeddedauthserver.go | 8 + .../runner/embeddedauthserver_test.go | 59 +++ pkg/oauthproto/discovery.go | 263 ++++++++++- pkg/oauthproto/discovery_test.go | 434 +++++++++++++++++- pkg/oauthproto/errors.go | 20 +- 10 files changed, 1163 insertions(+), 41 deletions(-) diff --git a/docs/server/docs.go b/docs/server/docs.go index 89126fc936..aef6944614 100644 --- a/docs/server/docs.go +++ b/docs/server/docs.go @@ -411,6 +411,36 @@ const docTemplate = `{ }, "type": "object" }, + "github_com_stacklok_toolhive_pkg_authserver.DCRUpstreamConfig": { + "description": "DCRConfig enables RFC 7591 Dynamic Client Registration against the\nupstream authorization server.

RFC 6749 §6 says the AS SHOULD treat omission as equal to "the scope originally granted", but in practice some authorization servers — notably Microsoft Entra ID's v1 token issuer — silently narrow refreshed tokens to the user's default consent set (e.g. Microsoft Graph User.Read), dropping any custom resource scopes the original token carried. Real-world impact: an embedded auth server flow against Entra ID with a custom resource scope (e.g. `api:///session:role-any` for Snowflake's external OAuth integration) issues fresh tokens with the correct scope, but every refreshed token comes back with `scp` reduced to `User.Read`. Downstream resources reject the refreshed token because the scope they enforce on is missing, even though the bearer token is otherwise valid. Users see ~1h of working access followed by silent failure until they re-authenticate. Send `scope` explicitly on refresh, populated from the configured scope set. Per RFC 6749 §6 this is permitted ("MUST NOT include any scope not originally granted by the resource owner") and is portable across compliant ASes. Replaces the TokenSource-based refresh with a direct POST to the token endpoint so the scope parameter can be set. Mirrors the parsing semantics of golang.org/x/oauth2 (caps `expires_in` at MaxInt32 to avoid time arithmetic overflow on non-spec emitters), preserves the existing refresh token when the AS doesn't issue a new one (RFC 6749 §6 allows this), and keeps the existing error-shape contract (`token request failed: : `). Tests: - new: refresh request includes the configured scope set verbatim - new: original refresh token is preserved when the AS omits one - existing tests pass without modification - integration test against mockoidc passes Signed-off-by: Dallin Stevens --- pkg/authserver/upstream/oauth2.go | 34 ++++++--- pkg/authserver/upstream/oauth2_test.go | 96 ++++++++++++++++++++++++++ 2 files changed, 121 insertions(+), 9 deletions(-) diff --git a/pkg/authserver/upstream/oauth2.go b/pkg/authserver/upstream/oauth2.go index b32ed6544f..8d0f349685 100644 --- a/pkg/authserver/upstream/oauth2.go +++ b/pkg/authserver/upstream/oauth2.go @@ -30,7 +30,6 @@ import ( "net/url" "os" "strings" - "time" "golang.org/x/oauth2" @@ -539,6 +538,16 @@ func (p *BaseOAuth2Provider) exchangeCodeForTokens(ctx context.Context, code, co } // RefreshTokens refreshes the upstream IDP tokens. +// +// Sends `scope` explicitly.

charset=UTF-8 Content-Transfer-Encoding: 8bit * test(e2e): add all-client LLM gateway e2e matrix + fix secret provider bugs Fixes two bugs discovered while building the new test suite: 1. Add "secret" to informationalCommands so thv secret provider environment does not require a container runtime to be available. 2. Fix GetSystemSecretsProvider to call GetProviderType() before checking SetupCompleted, so the TOOLHIVE_SECRETS_PROVIDER env var is respected when interactive secrets setup has not been completed. Adds test/e2e/cli_llm_all_clients_test.go with 16 e2e tests (label: llm && clients) covering all 6 supported LLM gateway clients, proxy DNS-rebinding protection, port conflict handling, and 4 edge cases. Tests use an in-process mock OIDC server and fake browser stubs — no Docker or real credentials needed. Adds test/llm-mock-env/ for manual end-to-end testing with a local mock OIDC + LLM gateway.

charset=UTF-8 Content-Transfer-Encoding: 8bit Closes #5123 Stores TLSSkipVerify in the LLM config section and threads it through to every layer: - pkg/llm/config.go: add TLSSkipVerify field to Config; SetOptions uses *bool so that --tls-skip-verify=false explicitly clears the stored value rather than being silently ignored as a zero value - pkg/llm/manage.go: SetFields applies the pointer, Show() prints a WARNING line when the flag is set - pkg/llm/setup.go: pass TLSSkipVerify through ToolApplyConfig; extract configureDetectedTools() and warnTLSSkipVerify() helpers (gocyclo) - pkg/llm/proxy/proxy.go: add Option / WithTLSSkipVerify() functional option; New() accepts variadic opts; sets InsecureSkipVerify on the upstream transport when the flag is true - pkg/client/llm_gateway.go: add TLSSkipVerify to LLMApplyConfig; add NodeTLSRejectUnauthorized case to llmValueForSpec(); extract applyLLMGatewayKeys / addLLMKey / removeLLMKey helpers (gocyclo); ClearWhenEmpty on LLMGatewayKeySpec removes the JSON key when the flag is cleared rather than leaving a stale "0" in the settings file - pkg/client/config.go: add NODE_TLS_REJECT_UNAUTHORIZED key spec (ClearWhenEmpty=true) to ClaudeCode and GeminiCli (the two direct-mode Node.js tools); proxy-mode tools (Cursor, VSCode, Xcode, …) are covered by WithTLSSkipVerify on the proxy transport - cmd/thv/app/llm.go: wire --tls-skip-verify into setup, config set, and proxy start; proxy start overrides the stored value when the flag is explicitly passed Co-authored-by: taskbot --- cmd/thv/app/llm.go | 43 +++++++++++++-- pkg/client/config.go | 17 ++++-- pkg/client/llm_gateway.go | 99 ++++++++++++++++++++++++++-------- pkg/client/llm_gateway_test.go | 85 +++++++++++++++++++++++++++++ pkg/client/test_support.go | 19 ++++--- pkg/llm/config.go | 1 + pkg/llm/manage.go | 34 +++++++----- pkg/llm/manage_test.go | 46 ++++++++++++++++ pkg/llm/proxy/proxy.go | 30 ++++++++++- pkg/llm/proxy/proxy_test.go | 45 ++++++++++++++++ pkg/llm/setup.go | 91 +++++++++++++++++++++++-------- 11 files changed, 439 insertions(+), 71 deletions(-) diff --git a/cmd/thv/app/llm.go b/cmd/thv/app/llm.go index 51870dc963..a4e2138f66 100644 --- a/cmd/thv/app/llm.go +++ b/cmd/thv/app/llm.go @@ -72,7 +72,10 @@ func newConfigCommand() *cobra.Command { } func newConfigSetCommand() *cobra.Command { - var opts llm.SetOptions + var ( + opts llm.SetOptions + tlsSkipVerify bool + ) cmd := &cobra.Command{ Use: "set", @@ -85,7 +88,10 @@ Example: --issuer https://auth.example.com \ --client-id my-client-id`, Args: cobra.NoArgs, - RunE: func(_ *cobra.Command, _ []string) error { + RunE: func(cmd *cobra.Command, _ []string) error { + if cmd.Flags().Changed("tls-skip-verify") { + opts.TLSSkipVerify = &tlsSkipVerify + } return config.UpdateConfig(func(c *config.Config) error { return c.LLM.SetFields(opts) }) @@ -98,6 +104,8 @@ Example: cmd.Flags().StringVar(&opts.Audience, "audience", "", "OIDC audience (optional)") cmd.Flags().IntVar(&opts.ProxyPort, "proxy-port", 0, "Localhost proxy listen port (omit to keep current;

ToolHive runtime auto-detection only probed /var/run/docker.sock and macOS-specific paths, so on a Linux host with only Docker Desktop installed IsAvailable returned false and CheckRuntimeAvailable failed with "no container runtime available" -- even though docker ps in the same shell worked fine via the active context. Add the Linux Docker Desktop socket to the discovery list so auto-detection finds it without requiring TOOLHIVE_DOCKER_SOCKET. Wrap the system socket path in an unexported package variable so tests can redirect the system probe to a sandbox path. * Add unit tests for Docker socket discovery Cover three cases for Docker socket auto-detection: - discovery of the new Docker Desktop on Linux socket at $HOME/.docker/desktop/docker.sock when no system socket is present; - TOOLHIVE_DOCKER_SOCKET env override wins over filesystem discovery; - ErrRuntimeNotFound when no socket is reachable. The tests redirect the system socket probe via the unexported systemDockerSocketPath variable so they stay hermetic on machines that already have /var/run/docker.sock. * Document Docker Desktop on Linux socket path Match the documented runtime discovery order to the code by adding the Linux Docker Desktop socket path next to the existing macOS-specific entries in docs/arch/01-deployment-modes.md. --- docs/arch/01-deployment-modes.md | 1 + pkg/container/docker/sdk/client_unix.go | 28 +++++- pkg/container/docker/sdk/client_unix_test.go | 92 ++++++++++++++++++++ pkg/container/docker/sdk/factory.go | 4 + 4 files changed, 121 insertions(+), 4 deletions(-) create mode 100644 pkg/container/docker/sdk/client_unix_test.go diff --git a/docs/arch/01-deployment-modes.md b/docs/arch/01-deployment-modes.md index d438618088..45f50b2f32 100644 --- a/docs/arch/01-deployment-modes.md +++ b/docs/arch/01-deployment-modes.md @@ -101,6 +101,7 @@ The CLI automatically detects container runtimes in this order: - `$TOOLHIVE_DOCKER_SOCKET` (if set) - `/var/run/docker.sock` - `~/.docker/run/docker.sock` (Docker Desktop on macOS) + - `~/.docker/desktop/docker.sock` (Docker Desktop on Linux) - `~/.rd/docker.sock` (Rancher Desktop on macOS) - `~/.orbstack/run/docker.sock` (OrbStack on macOS) diff --git a/pkg/container/docker/sdk/client_unix.go b/pkg/container/docker/sdk/client_unix.go index a0b22cd6fa..c7d81d358f 100644 --- a/pkg/container/docker/sdk/client_unix.go +++ b/pkg/container/docker/sdk/client_unix.go @@ -166,17 +166,22 @@ func findPodmanSocket() (string, error) { return "", fmt.Errorf("podman socket not found in standard locations") } +// systemDockerSocketPath is the system-wide Docker socket path probed by +// findDockerSocket.

The adapter in cmd/thv/app/llm.go did nothing but field-copy between them, meaning every new field had to be added in three places. Introduce pkg/llmgateway with a single ApplyConfig struct imported by both packages. The adapter method is now a one-liner. Closes #5137.

WriteFiles (MkdirAll on the parent, path-traversal guard) and the OCI packager (filepath.WalkDir, independent maxSkillFiles/maxSkillTotalSize caps) already support nested paths, so the only missing piece was actually walking the subtree. Switch collectFiles to go-git's recursive *FileIter via tree.Files(). The iterator walks subtrees, skips submodules and tree entries, and yields forward-slash relative paths fit for both WriteContainedFile and the packager. Companion files under references/, scripts/, infrastructure/, etc. now reach the resolved skill bundle. The existing in-memory clone is still bounded by LimitedFs in pkg/git, so no new limits are required here. * Test nested file resolution for git skills Build a small in-memory repo with a layout that includes references/, scripts/, and a deep/nested/dir/ entry, then assert that Resolve returns nested files with forward-slash paths, that files outside the requested skill subtree are not picked up, and that the no-basePath case walks the entire tree. Locks in the recursive walk introduced in the previous commit; would have failed against the old flat collectFiles. * Test nested paths through skill WriteFiles Cover WriteFiles with FileEntry.Path values containing subdirectories (references/foo.md, scripts/nested/run.sh, deep/nested/dir/note.txt). WriteContainedFile already does MkdirAll on the parent and caps modes at 0644; this test guards against future regressions and verifies that intermediate directories are created on disk. --- pkg/skills/gitresolver/resolver.go | 44 ++++----- pkg/skills/gitresolver/resolver_test.go | 117 ++++++++++++++++++++++++ pkg/skills/gitresolver/writer_test.go | 31 +++++++ 3 files changed, 168 insertions(+), 24 deletions(-) diff --git a/pkg/skills/gitresolver/resolver.go b/pkg/skills/gitresolver/resolver.go index 85328be412..deb1d58f7c 100644 --- a/pkg/skills/gitresolver/resolver.go +++ b/pkg/skills/gitresolver/resolver.go @@ -14,6 +14,8 @@ import ( "regexp" "time" + "github.com/go-git/go-git/v5/plumbing/object" + "github.com/stacklok/toolhive/pkg/git" "github.com/stacklok/toolhive/pkg/skills" ) @@ -151,9 +153,9 @@ func (r *defaultResolver) Resolve(ctx context.Context, ref *GitReference) (*Reso return nil, fmt.Errorf("invalid skill name in SKILL.md: %w", err) } - // Collect all files in the skill directory. - // For now, we read SKILL.md as the primary file.

Falls back to DCR gracefully if the AS rejects the CIMD client_id. The CIMD check runs inside PerformOAuthFlow before the DCR gate so it works regardless of which issuer discovery path was taken (configured issuer, realm-derived, or resource metadata). Includes hack/mock-cimd-server for local E2E testing. Closes #4826 Co-Authored-By: Claude Sonnet 4.6 (1M context) * Fix lint issues and resolve pkg/oauth → pkg/oauthproto rename - Move cimd.go and cimd_test.go to pkg/oauthproto, update package declaration - Update imports from pkg/oauth to pkg/oauthproto in handler.go and handler_test.go - Fix CodeQL SSRF alert in mock-cimd-server: validate redirect_uri is localhost before making outbound request; use io.Discard to drain response body - Fix revive lint: unused parameter, redefined builtin min - Fix errcheck lint: handle resp.Body.Close error Co-Authored-By: Claude Sonnet 4.6 (1M context) * Clean up: remove manual test artifacts, extend E2E mock server - Remove hack/mock-cimd-server: was added for a manual test session but has no E2E test coverage and does not belong in the final PR - Remove toolhive-client-metadata.json: the authoritative copy is in the infra repo (stacklok/infra#4549) where it gets deployed to https://toolhive.dev/oauth/client-metadata.json via CloudFront - Add client_id_metadata_document_supported: true to test/e2e/oidc_mock.go discovery document so the existing E2E mock server is CIMD-capable for future integration tests Co-Authored-By: Claude Sonnet 4.6 (1M context) * Address jhrozek review comments - cimd.go: collapse duplicate godoc; expand IsClientIDMetadataDocumentURL comment with rationale for broad HTTPS check and Phase 2 TODO - config.go: clear CachedCIMDClientID in ClearCachedClientCredentials; note in doc comment that the restart-skip reader is deferred (#2728) - discovery.go: extract applyDiscoveryPreCheck helper to stay under cyclomatic complexity limit; populate discovered endpoints on config to prevent double-fetch on the DCR path; add SkipCIMD to OAuthFlowConfig; emit WARN when AS discovery fetch fails instead of silently falling back - handler.go: fix retry-loop bug — set SkipCIMD=true on retry so the pre-check does not re-apply the CIMD URL; narrow retry trigger to invalid_client / unauthorized_client only via isCIMDRejectionError - handler_test.go: add TestIsCIMDRejectionError covering all error cases the RFC specifies (invalid_client/unauthorized_client retry; invalid_request/other errors propagate) PKCE is already enforced unconditionally in createOAuthConfig (lines 659/675 of discovery.go) for all flows including CIMD — no change needed. Co-Authored-By: Claude Sonnet 4.6 (1M context) * Clarify CIMD priority chain and fix issuer discovery paths - Move explicit priority chain (P1/P2/P3 with comments) to performOAuthFlow; remove duplicate CIMD block from buildOAuthFlowConfig so it is a pure config builder with no registration logic - Fix Priority 1 and Priority 2 in discoverIssuerAndScopes: fetch AS discovery document even when issuer is pre-configured or realm-derived, so ClientIDMetadataDocumentSupported is populated and CIMD detection works on those paths - Remove TestBuildOAuthFlowConfig_CIMD: CIMD behaviour is now tested via TestIsCIMDRejectionError and the priority chain in performOAuthFlow Co-Authored-By: Claude Sonnet 4.6 (1M context) * Fix doc comments across CIMD changes - discovery.go: restore precise port-resolution comment explaining why order matters (DCR allows fallback, pre-registered/CIMD clients require exact port); consolidate CIMD note into the else-branch comment - handler.go: remove incorrect RFC 6749 §5.2 reference from isCIMDRejectionError — §5.2 covers token endpoint errors but CIMD rejection happens at the authorization endpoint; use plain RFC 6749 reference without a specific section Co-Authored-By: Claude Sonnet 4.6 (1M context) * Add E2E tests for CIMD authentication flow Two test cases under Label("remote", "auth", "cimd"): 1. AS advertises CIMD support: verifies thv run presents ToolHiveClientMetadataDocumentURL as client_id, includes PKCE code_challenge, and never calls /oauth/register (DCR skipped). 2. AS does not advertise CIMD: verifies thv run falls back to DCR and does not use the CIMD metadata URL as client_id. Uses a minimal httptest-based mock AS (cimdMockAuthServer) rather than OIDCMockServer because Fosite's GetClient rejects HTTPS client IDs that are not pre-registered — CIMD requires accepting any valid HTTPS URL as client_id. Co-Authored-By: Claude Sonnet 4.6 (1M context) * Restore CachedCIMDClientID with reader, extract shouldUseCIMD, fix error check CachedCIMDClientID: - Re-introduce the field with a clear doc comment explaining why it is kept separate from CachedClientID (independent lifecycle — DCR credential rotation must not clear the stable CIMD URL) - Guard clientCredentialsPersister so CIMD URLs are NOT stored in CachedClientID; they go to CachedCIMDClientID instead - Implement the reader in resolveClientCredentials: CIMD URL is returned as client_id for token refresh on restart, checked before DCR credentials; this was the deferred reader Jakub flagged - ClearCachedClientCredentials does not clear CachedCIMDClientID (documented in its comment) shouldUseCIMD: - Extract the four-condition CIMD predicate into a named helper, mirroring shouldDynamicallyRegisterClient (jhrozek non-blocking) isCIMDRejectionError: - Replace strings.Contains with errors.As(*oauth2.RetrieveError) to avoid substring collisions and format coupling (jhrozek non-blocking) - Update TestIsCIMDRejectionError to use real *oauth2.RetrieveError values matching what golang.org/x/oauth2 actually returns Co-Authored-By: Claude Sonnet 4.6 (1M context) * Fix isCIMDRejectionError to handle auth-endpoint rejections CIMD rejection surfaces from two distinct stages: - Authorization endpoint: AS redirects callback with error=invalid_client; flow.go formats this as "OAuth error: - " (plain error, not *oauth2.RetrieveError). - Token endpoint: *oauth2.RetrieveError with ErrorCode set. The previous errors.As-only check missed auth-endpoint rejections entirely, meaning the DCR fallback never triggered when the AS rejected the CIMD URL at the authorize step. Fix by checking errors.As first (precise, for token endpoint), then strings.HasPrefix for the auth-endpoint format. Update TestIsCIMDRejectionError to cover both error sources. Co-Authored-By: Claude Sonnet 4.6 (1M context) * Merge main and regenerate swagger docs Brings in changes from main (v0.25.0 release cycle) and regenerates the swagger documentation to match, fixing the Docs CI check. * Merge CIMD flag from OAuth AS metadata when OIDC doc lacks it Some authorization servers (e.g. Granola) advertise client_id_metadata_document_supported only in their RFC 8414 /.well-known/oauth-authorization-server document, not in the OIDC /.well-known/openid-configuration document. When discoverOIDCEndpointsWithClientAndValidation falls back to the OAuth AS metadata to fetch a missing registration_endpoint, it now also merges ClientIDMetadataDocumentSupported so CIMD detection works correctly for servers that split their metadata across the two well-known endpoints. Tested against Granola (https://mcp-auth.granola.ai): CIMD URL now appears as client_id in the authorize request instead of a DCR-issued opaque identifier.

From 31e0307405f5cc54a81ea4be586b6aa36ae5fd51 Mon Sep 17 00:00:00 2001 From: Jakub Hrozek Date: Fri, 1 May 2026 11:40:33 +0100 Subject: [PATCH 081/291] Carry forward upstream refresh token on re-authorization (#5132) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Add GetLatestUpstreamTokensForUser to storage Introduces a secondary upstream-token lookup keyed on (userID, providerID) on the UpstreamTokenStorage interface. The OAuth callback handler will use this in a follow-on commit to preserve a previously-issued refresh token when the upstream IdP omits refresh_token on re-authorization (e.g. Google without prompt=consent), which today silently clobbers the prior good RT and forces a refresh-token-orphaning loop. This commit only adds the interface surface plus stub implementations on both backends that return ErrNotFound. The real Memory and Redis logic, the callback wiring, and tests land in subsequent commits so each diff stays small and independently reviewable. The godoc explicitly calls out the liveness contract (expired rows are returned, callers handle it) and the cross-identity caller responsibility (verify UpstreamSubject before reusing the prior RT) so future callers cannot misuse the lookup. Refs #5047 * Implement GetLatestUpstreamTokensForUser for memory Replaces the Step 1 stub on MemoryStorage with the real lookup. Iterates the upstream-tokens map under RLock, filters by (UserID, ProviderID), and picks the row with the highest ExpiresAt. Expired access tokens are intentionally returned (matching the interface contract) so the OAuth callback can carry forward a still-valid refresh token even when the access token is dead. Returns a defensive deep copy on hit and the same wrapped ErrNotFound shape that GetUpstreamTokens uses on miss, so callers cannot accidentally mutate stored state through the returned pointer. Adds a 7-case table-driven test covering: no match, one match (with a deep-copy mutation assertion), latest-by-ExpiresAt across three rows, different-user/different-provider misses, expired-row tolerance, and zero-ExpiresAt losing to non-zero. Refs #5047 * Implement GetLatestUpstreamTokensForUser for redis Replaces the Step 1 stub on RedisStorage with the real lookup, using the existing KeyTypeUserUpstream:{userID} reverse-index set already maintained atomically by storeUpstreamTokensScript. The read path is plain Go (no Lua script) since atomicity buys nothing on a read-only path: the worst case is reading a slightly-stale row, which is acceptable for the carry-forward use case. Mirrors the SMembers -> MGet -> unmarshal pattern from GetAllUpstreamTokens and tolerates dangling SMEMBERs (per-provider key TTL-evicted, set member lingers), nullMarker deletion tombstones, and corrupt JSON. Filters on the deserialized ProviderID rather than parsing the key string so the implementation survives any future key-format change. Picks the winner by the stored unix-timestamp ExpiresAt; zero (the no-expiry sentinel) loses to any real timestamp. Adds input validation for empty userID/providerID matching the rest of the type's public API. The Memory backend has the same gap and should be fixed as a follow-up; it's left untouched here to keep this commit scoped to the Redis backend. Adds a 9-case table-driven unit test covering all the cases from the Memory backend plus a stale-index-entry case (dangling SMEMBER injected via miniredis SAdd) and a two-zero-ExpiresAt case (verifies non-strict ordering without locking down iteration order). Refs #5047 * Carry forward upstream refresh token on callback The OAuth callback handler now preserves a previously-issued upstream refresh token when the IdP omits refresh_token on re-authorization. This is common across major IdPs: Google omits unless prompt=consent and access_type=offline are forced; Microsoft Entra omits when consent was already granted; GitHub, Okta, Auth0, and Keycloak behave similarly. In every case the prior RT remains valid at the IdP — but today the callback writes the empty value verbatim, clobbering the stored RT and forcing the next refresh attempt to fail, which puts the user in a re-auth-orphans-RT loop. The carry-forward logic mirrors the existing pattern in upstreamTokenRefresher.RefreshAndStore. It uses the new storage method GetLatestUpstreamTokensForUser to find the most recent prior row for (user, provider) and copies the prior RefreshToken into the new row. The prior row's UpstreamSubject must equal the current providerSubject as defense-in-depth; this guard is dormant given the current identity model (ResolveUser keys on (providerID, providerSubject) and same- provider account-linking is not implemented) but protects future flows. Storage failures during the lookup log a Warn and continue with the empty RT — failing the callback would be a worse user experience than the (already broken) status quo, and the next refresh attempt will produce a clean error path the user can retry from. The implementation lives in a private helper to keep CallbackHandler under the gocyclo threshold; the call site is between storageTokens construction and StoreUpstreamTokens so the in-place mutation is visible at the point of use. Adds 5 handler tests covering: positive carry-forward, UpstreamSubject mismatch (no carry), fresh-RT-from-IdP wins (carry-forward short-circuited), no-prior-row (status quo for first auth), and storage-error-non-fatal (callback completes with empty RT instead of returning 500). Refs #5047 * Add integration test for re-auth refresh token carry-forward Drives the full authorize -> callback flow against mockoidc and a real MemoryStorage so the carry-forward behavior is validated end-to-end, not just at the gomock-handler boundary. mockoidc unconditionally issues refresh_token on the authorization_code grant with no API to suppress the field, so the test wires a small reverse-proxy (rtStrippingProxy) between the auth server and mockoidc. When the test toggles the strip flag (atomic.Bool — required, otherwise the race detector flags the read on httptest's request goroutines), the proxy unmarshals mockoidc's token response, deletes the refresh_token key, and re-marshals before forwarding. The key is then absent from the wire JSON exactly as Google, Entra, GitHub, Okta and Auth0 behave on a silent re-authorization, which is what the underlying bug actually reproduces in production. Three legs: 1. Initial authorize -> callback with RT preserved verbatim. Captures the RT for later comparison. 2. Strip flag flipped on, second authorize -> callback for the same user. Asserts the new (different sessionID) row carries the leg-1 RT forward. 3. Different upstream subject -> ResolveUser mints a new internal user; the carry-forward lookup returns ErrNotFound and the new row stays empty. Confirms the carry-forward fires only when warranted. The UpstreamSubject == providerSubject guard inside the callback is covered by the handler-level unit test added in the previous commit; exercising it end-to-end here would require either a contrived storage hack or same-provider account-linking (not implemented today). Note on offline_access: real IdPs require this scope before issuing a refresh token, but mockoidc's ScopesSupported allowlist rejects it as invalid_scope. The test does not request the scope as a result. This is a fixture limitation; the carry-forward regression assertion is unaffected because mockoidc returns the RT regardless. Refs #5047 * Populate SessionExpiresAt in GetLatestUpstreamTokensForUser Both backend implementations of GetLatestUpstreamTokensForUser dropped SessionExpiresAt from the returned struct, while the sibling readers GetUpstreamTokens (memory) and unmarshalUpstreamTokens (redis) populate it. The interface return type makes no "partial copy" caveat, so any future caller doing Get-then-Store would lose the storage TTL fallback bound that SessionExpiresAt provides on rows whose upstream IdP did not issue an expires_in. Today's only caller (maybeCarryForwardRefreshToken) reads only RefreshToken and UpstreamSubject, so this is latent. Fixing now to close the contract trap before the deferred Root Cause A rekey introduces a caller that does treat the result as round-trippable. * Extract upstream-tokens conversion helpers The storage package had four sites doing field-by-field construction of UpstreamTokens — three in the memory backend (defensive deep copies) and two in the redis backend (storedUpstreamTokens int64→time.Time conversion). Each site is a place where a future field addition can be silently missed; the SessionExpiresAt drop in the previous commit is an example of that class of bug. Extract a free function cloneUpstreamTokens for the memory backend (used at 3 sites) and a (*storedUpstreamTokens).toUpstreamTokens method for the redis backend (used at 2 sites). No behavior change. * Add round-trip test for UpstreamTokens fields The existing tests for GetLatestUpstreamTokensForUser asserted only on RefreshToken — the previous SessionExpiresAt drop slipped through because no test exercised whole-struct round-tripping. Add a focused subtest in each backend that builds a fully-populated UpstreamTokens fixture, stores it, retrieves it, and asserts whole-struct equality. Catches the SessionExpiresAt regression and any future field that fails to round-trip through the storage layer. * Test empty-RT prior row in carry-forward and broaden assertions The prior.RefreshToken != "" guard in maybeCarryForwardRefreshToken was untested: every existing case either carried (non-empty prior RT and matching subject), failed earlier (subject mismatch / fresh IdP RT / nil prior / storage error), or never reached the guard. The state is reachable in production — e.g. Google can omit refresh_token even on first auth without prompt=consent, leaving a leg-1 row with empty RT that a leg-2 lookup will return. Add a case where the prior row exists with matching subject but empty RefreshToken, and assert no carry-forward happens. Strengthen the shared assertion block with sanity checks on AccessToken, IDToken, UpstreamSubject and a non-zero ExpiresAt across all cases. Without them, a regression that early-returns from the callback before StoreUpstreamTokens would still pass an assertion that only checks RefreshToken. * Prefer non-expiring rows in GetLatestUpstreamTokensForUser The previous tie-breaker used "highest ExpiresAt wins" with zero (the no-expiry sentinel) treated as the smallest int64 — so non-expiring rows always lost to any finite expiry. That was inconsistent with the rest of the package, which treats zero ExpiresAt as "alive forever": IsExpired returns false for zero, cleanupExpired skips zero entries, and marshalUpstreamTokensWithTTL only writes a Redis TTL when ExpiresAt is non-zero. PR #5092 (a98c9918e) reshaped the whole storage stack on that premise — Slack user tokens and GitHub OAuth App tokens deliberately omit expires_in because they are genuinely non-expiring. Flip the rule to align with the rest of the package: a non-expiring row beats any finite expiry; among finite expiries, the latest still wins. Both backends use a small predicate helper (candidateBeatsWinner for time.Time, candidateBeatsWinnerInt64 for the Redis epoch) to keep the comparison readable. The carry-forward caller is largely unaffected today because Slack / GitHub OAuth App rows store an empty RefreshToken (non-expiring access tokens have no RT) and the prior.RefreshToken != "" guard rejects them either way. The flip matters for future callers that read the access token from the returned row, and for the rare provider that emits both zero ExpiresAt and a non-empty refresh token. Update the interface godoc and rename the existing zero_expires_at_loses_to_nonzero subtest to zero_expires_at_wins_over_nonzero in both backends. Add a memory-side two_zero_expires_at_rows case to match the existing Redis coverage. --- pkg/authserver/integration_test.go | 277 ++++++++++++++++++ pkg/authserver/server/handlers/callback.go | 42 +++ .../server/handlers/callback_test.go | 155 ++++++++++ .../server/handlers/helpers_test.go | 36 ++- pkg/authserver/storage/memory.go | 102 +++++-- pkg/authserver/storage/memory_test.go | 200 +++++++++++++ pkg/authserver/storage/mocks/mock_storage.go | 30 ++ pkg/authserver/storage/redis.go | 166 +++++++++-- pkg/authserver/storage/redis_test.go | 206 +++++++++++++ pkg/authserver/storage/types.go | 42 ++- 10 files changed, 1192 insertions(+), 64 deletions(-) diff --git a/pkg/authserver/integration_test.go b/pkg/authserver/integration_test.go index 63152b686a..48aeba95d0 100644 --- a/pkg/authserver/integration_test.go +++ b/pkg/authserver/integration_test.go @@ -16,6 +16,7 @@ import ( "net/http/httptest" "net/url" "strings" + "sync/atomic" "testing" "time" @@ -2506,3 +2507,279 @@ func TestIntegration_MultiUpstreamChain_MixedExpiryOrderings_Redis(t *testing.T) }) } } + +// ============================================================================ +// Callback Refresh-Token Carry-Forward Integration Tests +// ============================================================================ + +// rtStrippingProxy wraps a mockoidc server and intercepts its token endpoint. +// When stripRT is true the proxy omits the "refresh_token" field from every +// token-endpoint response, replicating the common IdP behavior where the RT +// is only issued on the first authorization (e.g. Google without prompt=consent). +// +// All other endpoints (authorize, userinfo, jwks, discovery) are forwarded +// verbatim so that the real mockoidc can still sign tokens and serve user info. +// +// We use this proxy instead of the real mockoidc token endpoint for the second +// authorize → callback leg because mockoidc's setTokens() always generates a +// refresh_token for authorization_code grants and offers no API to suppress it. +type rtStrippingProxy struct { + stripRT atomic.Bool + target string // real mockoidc base URL (e.g. "http://127.0.0.1:PORT") +} + +func (p *rtStrippingProxy) ServeHTTP(w http.ResponseWriter, r *http.Request) { + // Forward the request to the real mockoidc. + proxyURL := p.target + r.URL.RequestURI() + proxyReq, err := http.NewRequestWithContext(r.Context(), r.Method, proxyURL, r.Body) + if err != nil { + http.Error(w, "proxy: failed to build request", http.StatusInternalServerError) + return + } + proxyReq.Header = r.Header.Clone() + + resp, err := http.DefaultTransport.RoundTrip(proxyReq) + if err != nil { + http.Error(w, "proxy: upstream request failed", http.StatusBadGateway) + return + } + defer resp.Body.Close() + + body, err := io.ReadAll(resp.Body) + if err != nil { + http.Error(w, "proxy: failed to read response", http.StatusInternalServerError) + return + } + + // Strip refresh_token when the flag is set and this is the token endpoint. + if p.stripRT.Load() && r.URL.Path == "/oidc/token" { + var m map[string]json.RawMessage + if jsonErr := json.Unmarshal(body, &m); jsonErr == nil { + delete(m, "refresh_token") + if rewritten, jsonErr := json.Marshal(m); jsonErr == nil { + body = rewritten + } + } + } + + // Copy response headers and status code. + for k, vs := range resp.Header { + for _, v := range vs { + w.Header().Add(k, v) + } + } + // Drop the upstream Content-Length; the body may have been rewritten (RT + // stripped) so the original length is stale. net/http will set it correctly + // from the buffered body. + w.Header().Del("Content-Length") + w.WriteHeader(resp.StatusCode) + _, _ = w.Write(body) +} + +// setupTestServerWithRTProxy creates a test server backed by a real mockoidc but +// with the upstream OAuth2 provider pointing to the rtStrippingProxy instead of +// the mockoidc server directly.

From 9f8256f88b0caadd52082ab6bda33d7d36075566 Mon Sep 17 00:00:00 2001 From: Muhammad Amir Ejaz Date: Fri, 1 May 2026 17:02:12 +0500 Subject: [PATCH 082/291] Add follow-up CIMD E2E and unit tests (#5130) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Support CIMD as preferred OAuth client registration for thv run When a remote authorization server advertises client_id_metadata_document_supported in its discovery document, thv run now presents https://toolhive.dev/oauth/client-metadata.json as its client_id instead of performing a DCR round-trip. Falls back to DCR gracefully if the AS rejects the CIMD client_id. The CIMD check runs inside PerformOAuthFlow before the DCR gate so it works regardless of which issuer discovery path was taken (configured issuer, realm-derived, or resource metadata). Includes hack/mock-cimd-server for local E2E testing. Closes #4826 Co-Authored-By: Claude Sonnet 4.6 (1M context) * Fix lint issues and resolve pkg/oauth → pkg/oauthproto rename - Move cimd.go and cimd_test.go to pkg/oauthproto, update package declaration - Update imports from pkg/oauth to pkg/oauthproto in handler.go and handler_test.go - Fix CodeQL SSRF alert in mock-cimd-server: validate redirect_uri is localhost before making outbound request; use io.Discard to drain response body - Fix revive lint: unused parameter, redefined builtin min - Fix errcheck lint: handle resp.Body.Close error Co-Authored-By: Claude Sonnet 4.6 (1M context) * Clean up: remove manual test artifacts, extend E2E mock server - Remove hack/mock-cimd-server: was added for a manual test session but has no E2E test coverage and does not belong in the final PR - Remove toolhive-client-metadata.json: the authoritative copy is in the infra repo (stacklok/infra#4549) where it gets deployed to https://toolhive.dev/oauth/client-metadata.json via CloudFront - Add client_id_metadata_document_supported: true to test/e2e/oidc_mock.go discovery document so the existing E2E mock server is CIMD-capable for future integration tests Co-Authored-By: Claude Sonnet 4.6 (1M context) * Address jhrozek review comments - cimd.go: collapse duplicate godoc; expand IsClientIDMetadataDocumentURL comment with rationale for broad HTTPS check and Phase 2 TODO - config.go: clear CachedCIMDClientID in ClearCachedClientCredentials; note in doc comment that the restart-skip reader is deferred (#2728) - discovery.go: extract applyDiscoveryPreCheck helper to stay under cyclomatic complexity limit; populate discovered endpoints on config to prevent double-fetch on the DCR path; add SkipCIMD to OAuthFlowConfig; emit WARN when AS discovery fetch fails instead of silently falling back - handler.go: fix retry-loop bug — set SkipCIMD=true on retry so the pre-check does not re-apply the CIMD URL; narrow retry trigger to invalid_client / unauthorized_client only via isCIMDRejectionError - handler_test.go: add TestIsCIMDRejectionError covering all error cases the RFC specifies (invalid_client/unauthorized_client retry; invalid_request/other errors propagate) PKCE is already enforced unconditionally in createOAuthConfig (lines 659/675 of discovery.go) for all flows including CIMD — no change needed. Co-Authored-By: Claude Sonnet 4.6 (1M context) * Clarify CIMD priority chain and fix issuer discovery paths - Move explicit priority chain (P1/P2/P3 with comments) to performOAuthFlow; remove duplicate CIMD block from buildOAuthFlowConfig so it is a pure config builder with no registration logic - Fix Priority 1 and Priority 2 in discoverIssuerAndScopes: fetch AS discovery document even when issuer is pre-configured or realm-derived, so ClientIDMetadataDocumentSupported is populated and CIMD detection works on those paths - Remove TestBuildOAuthFlowConfig_CIMD: CIMD behaviour is now tested via TestIsCIMDRejectionError and the priority chain in performOAuthFlow Co-Authored-By: Claude Sonnet 4.6 (1M context) * Fix doc comments across CIMD changes - discovery.go: restore precise port-resolution comment explaining why order matters (DCR allows fallback, pre-registered/CIMD clients require exact port); consolidate CIMD note into the else-branch comment - handler.go: remove incorrect RFC 6749 §5.2 reference from isCIMDRejectionError — §5.2 covers token endpoint errors but CIMD rejection happens at the authorization endpoint; use plain RFC 6749 reference without a specific section Co-Authored-By: Claude Sonnet 4.6 (1M context) * Add E2E tests for CIMD authentication flow Two test cases under Label("remote", "auth", "cimd"): 1. AS advertises CIMD support: verifies thv run presents ToolHiveClientMetadataDocumentURL as client_id, includes PKCE code_challenge, and never calls /oauth/register (DCR skipped). 2. AS does not advertise CIMD: verifies thv run falls back to DCR and does not use the CIMD metadata URL as client_id. Uses a minimal httptest-based mock AS (cimdMockAuthServer) rather than OIDCMockServer because Fosite's GetClient rejects HTTPS client IDs that are not pre-registered — CIMD requires accepting any valid HTTPS URL as client_id. Co-Authored-By: Claude Sonnet 4.6 (1M context) * Restore CachedCIMDClientID with reader, extract shouldUseCIMD, fix error check CachedCIMDClientID: - Re-introduce the field with a clear doc comment explaining why it is kept separate from CachedClientID (independent lifecycle — DCR credential rotation must not clear the stable CIMD URL) - Guard clientCredentialsPersister so CIMD URLs are NOT stored in CachedClientID; they go to CachedCIMDClientID instead - Implement the reader in resolveClientCredentials: CIMD URL is returned as client_id for token refresh on restart, checked before DCR credentials; this was the deferred reader Jakub flagged - ClearCachedClientCredentials does not clear CachedCIMDClientID (documented in its comment) shouldUseCIMD: - Extract the four-condition CIMD predicate into a named helper, mirroring shouldDynamicallyRegisterClient (jhrozek non-blocking) isCIMDRejectionError: - Replace strings.Contains with errors.As(*oauth2.RetrieveError) to avoid substring collisions and format coupling (jhrozek non-blocking) - Update TestIsCIMDRejectionError to use real *oauth2.RetrieveError values matching what golang.org/x/oauth2 actually returns Co-Authored-By: Claude Sonnet 4.6 (1M context) * Fix isCIMDRejectionError to handle auth-endpoint rejections CIMD rejection surfaces from two distinct stages: - Authorization endpoint: AS redirects callback with error=invalid_client; flow.go formats this as "OAuth error: - " (plain error, not *oauth2.RetrieveError). - Token endpoint: *oauth2.RetrieveError with ErrorCode set. The previous errors.As-only check missed auth-endpoint rejections entirely, meaning the DCR fallback never triggered when the AS rejected the CIMD URL at the authorize step. Fix by checking errors.As first (precise, for token endpoint), then strings.HasPrefix for the auth-endpoint format. Update TestIsCIMDRejectionError to cover both error sources. Co-Authored-By: Claude Sonnet 4.6 (1M context) * Add follow-up CIMD E2E and unit tests E2E (test/e2e/): - Extend cimdMockAuthServer with rejectCIMD option: first authorize request with a CIMD client_id returns error=invalid_client; subsequent requests with a DCR-issued client_id succeed normally - New test: "falls back to DCR when AS rejects the CIMD client_id" — verifies the full retry path end-to-end: CIMD attempted, rejected, DCR fallback fires, server becomes reachable Unit (pkg/auth/remote/handler_test.go): - TestResolveClientCredentials: 5 table-driven cases covering CachedCIMDClientID precedence over DCR and static credentials, empty-secret guarantee for CIMD, and DCR/static fallback when CachedCIMDClientID is empty Co-Authored-By: Claude Sonnet 4.6 (1M context) * Merge main and regenerate swagger docs Brings in changes from main (v0.25.0 release cycle) and regenerates the swagger documentation to match, fixing the Docs CI check. * Merge CIMD flag from OAuth AS metadata when OIDC doc lacks it Some authorization servers (e.g. Granola) advertise client_id_metadata_document_supported only in their RFC 8414 /.well-known/oauth-authorization-server document, not in the OIDC /.well-known/openid-configuration document. When discoverOIDCEndpointsWithClientAndValidation falls back to the OAuth AS metadata to fetch a missing registration_endpoint, it now also merges ClientIDMetadataDocumentSupported so CIMD detection works correctly for servers that split their metadata across the two well-known endpoints. Tested against Granola (https://mcp-auth.granola.ai): CIMD URL now appears as client_id in the authorize request instead of a DCR-issued opaque identifier.

charset=UTF-8 Content-Transfer-Encoding: 8bit * Add authserver DCR credential store and resolver Implements Phase 2 steps 2f/2c of the DCR story (#5038): - DCRCredentialStore interface with in-memory implementation keyed by (Issuer, RedirectURI, ScopesHash). No TTL — RFC 7591 registrations are long-lived and only purged by explicit deregistration. The ScopesHash tuple is designed to compose a Redis key segment in Phase 3 without redefining the canonical form. - resolveDCRCredentials performs cache lookup, authorization server metadata discovery (or direct registration endpoint), explicit endpoint override, auth-method intersection against the preference order private_key_jwt > client_secret_basic > client_secret_post > none, synthesis of {origin}/register when metadata omits registration_endpoint, and a single call to oauthproto.RegisterClientDynamically with the initial access token injected as Authorization: Bearer via a wrapping RoundTripper. - Resolution stored before returning, per the write-durable-first rule in .claude/rules/go-style.md. Address code review feedback on DCR resolver Fixed issues from code review: - HIGH: DCRUpstreamConfig.DiscoveryURL now honoured. Added oauthproto.FetchAuthorizationServerMetadataFromURL which fetches the operator-configured URL exactly (no well-known-path fallback) and enforces RFC 8414 §3.3 issuer equality. Updated field doc comments to match behaviour. - HIGH: TestResolveDCRCredentials_CacheHitShortCircuits rewritten to wire the count-everything server as the issuer and assert totalRequests == 0, so a regression that moved discovery before the cache lookup would actually fail the test. - MEDIUM: Added tests for discovered-scopes fallback and empty-scope omitted-field branches. - MEDIUM: Exposed oauthproto.NewDefaultDCRClient so newDCRHTTPClient inherits the canonical DCR timeout policy rather than duplicating it — future timeout changes propagate automatically. - MEDIUM: Replaced hand-rolled readAll / readAllResp helpers with io.ReadAll. - MEDIUM: Documented that direct RegistrationEndpoint disables server-capability negotiation. - MEDIUM: Documented that applyResolution always overwrites ClientID and explained the precondition enforcement. - MEDIUM: scopesHash now deduplicates (slices.Compact) so scope sets that differ only by duplicated values share a canonical digest. Test subtests updated accordingly. Co-Authored-By: Claude Opus 4.7 (1M context) * Address PR #5042 review feedback Refuse HTTP redirects on DCR registration so an upstream cannot 30x us into re-issuing the registration request — and the attached RFC 7591 initial access token — against a foreign origin. RFC 7591 §3 does not require redirect support, so refusing them is the conservative fix. - newDCRHTTPClient now sets http.Client.CheckRedirect to refuse all redirects (errDCRRedirectRefused), regardless of whether an initial access token is configured. The bearerTokenTransport itself is unchanged; the redirect block is the actual mitigation, not a header scrub inside RoundTrip. - New TestResolveDCRCredentials_DoesNotForwardBearerOnRedirect: stands up an upstream whose /register 302s to a separate "foreign" httptest server, and asserts (a) the resolver errors with errDCRRedirectRefused and (b) the foreign server receives zero requests — proving the bearer never crossed origins. Also includes a stray blank-line whitespace fix to discovery_test.go left from the earlier rebase conflict resolution. Co-Authored-By: Claude Opus 4.7 (1M context) * Address remaining PR #5042 review feedback Closes the 14 review threads from review #4199898531 that are scoped to this PR; #3 and #5 are intentionally deferred to PR #5044 which is the PR that consumes the ClientSecret plumbing and RedirectURI propagation. Behaviour fixes: - #2 synthesiseRegistrationEndpoint and resolveUpstreamRedirectURI now preserve the issuer's path component, so multi-tenant upstreams that ship DCR without advertising it (or this auth server when it itself has a tenant prefix in its issuer) keep their tenant prefix in the synthesised URL and the defaulted redirect URI. - #7 resolveDCRCredentials wraps registration in a package-level singleflight.Group keyed by DCRKey so concurrent callers for the same upstream coalesce into a single RFC 7591 registration. The leader's closure rechecks the cache before any network I/O so followers that arrive just after a Put returns observe the fresh entry. - #9 applyResolution writes ClientID only when the run-config copy leaves it empty, treating it symmetrically with the endpoint writes. This is defence-in-depth for callers that bypass the resolver's validateResolveInputs precondition check. - #10 the cfg.RegistrationEndpoint short-circuit branch in resolveDCREndpoints validates URL well-formedness and HTTPS-or- loopback locally, so a non-HTTPS endpoint fails before performRegistration constructs a bearer-token transport for it. - #13 endpointsFromMetadata validates discovered authorization_endpoint and token_endpoint before populating dcrEndpoints, so a self- consistent metadata document with http:// URLs cannot flow through to the auth-code or token-exchange path. Doc / scope: - #6 trust-assumption note added on DCRUpstreamConfig with a link to the follow-up SSRF-hardening issue (#5135) per the "Document Architectural Constraints" rule. - #8 NewInMemoryDCRCredentialStore doc now explicitly calls out what the in-memory store does and does NOT solve (cross-replica sharing, durability, cross-process write coordination). Test hygiene: - #4 deleted the literal-equals-literal dcrStaleAgeThreshold test that added no meaningful coverage. - #11 atomic.AddInt32 / LoadInt32 for wellKnownHits / customHits in TestFetchAuthorizationServerMetadataFromURL, matching the sibling pattern in dcr_test.go. - #12 new failingDCRStore test double + two cases asserting the cache.Get / cache.Put wrap messages ("dcr: cache lookup", "dcr: cache put") that operators see when a future Redis backend errors. - #14 renamed the TestNeedsDCR case from "client_id with dcr (invalid but returns false)" to "client_id wins over dcr_config (defensive AND semantic)" so the case label describes the intentional defensive behaviour rather than reading like a bug report. - #15 removed a //nolint:lll directive that was suppressing a non- existent violation (the line is 108 chars; the limit is 130). - #16 new TestInMemoryDCRCredentialStore_ConcurrentAccess fans out 16 goroutines doing alternating Put/Get against overlapping and disjoint keys, with a fail-fast deadline, so go test -race actually exercises the sync.RWMutex guard. New tests cover each behaviour change: - TestResolveDCRCredentials_SingleflightCoalescesConcurrentCallers pins exactly-one-registration under N concurrent callers. - TestSynthesiseRegistrationEndpoint_PreservesIssuerPath / TestResolveUpstreamRedirectURI_PreservesIssuerPath cover the path- preservation fix. - TestApplyResolution_DoesNotOverwritePreProvisionedClientID covers the symmetric ClientID write. - TestResolveDCREndpoints_DirectRegistrationEndpointValidated covers the local registration-endpoint guard. - TestEndpointsFromMetadata_RejectsInsecureDiscoveredEndpoints covers the metadata authz/token endpoint guard. Co-Authored-By: Claude Opus 4.7 (1M context) * Gate DCR "none" auth method on S256 PKCE advertisement RFC 7636 §4.2 / OAuth 2.1 require S256 PKCE for public clients. The resolver previously accepted the "none" token-endpoint auth method whenever an upstream advertised it, with no check against code_challenge_methods_supported. Registering as "none" against an upstream that only advertises "plain" — or omits the field entirely — would either break at runtime (our auth-code path always sends code_challenge_method=S256) or silently downgrade to a non-compliant plain-PKCE flow. - dcrEndpoints now carries codeChallengeMethodsSupported, populated from metadata.CodeChallengeMethodsSupported in endpointsFromMetadata. - selectTokenEndpointAuthMethod takes the slice as a second argument and skips "none" when S256 is not advertised, falling through to the next less-preferred method. When "none" is the only mutually supported method and S256 is missing, the function returns an explicit error citing the spec so operators see a clear failure at boot rather than a silent runtime downgrade. - TestResolveDCRCredentials_AuthMethodPreference's "falls back to none" case now also advertises S256 to reflect the compliant flow. - New TestResolveDCRCredentials_RefusesNoneWithoutS256 pins the rejection in both shapes the upstream can take it (field omitted, field lists only plain). Co-Authored-By: Claude Opus 4.7 (1M context) * Capture RFC 7591 client_secret_expires_at and refetch on expiry oauthproto decodes RFC 7591 §3.2.1 client_id_issued_at and client_secret_expires_at, but buildResolution dropped both. The authoritative consequence was for client_secret_expires_at: a non-zero upstream-asserted expiry was invisible to lookupCachedResolution, so the cache served an expired secret indefinitely, every token-endpoint call after the upstream's expiry would 401, and the resolver had no signal to refetch. The 90-day dcrStaleAgeThreshold added for Step 2g observability is a separate, heuristic signal ("consider rotating") and does not address this — the upstream-asserted expiry is authoritative. - DCRResolution now carries ClientIDIssuedAt and ClientSecretExpiresAt as time.Time. The wire convention "0 means absent / does not expire" maps to the zero time.Time so callers can use IsZero() uniformly, via a small epochSecondsToTime helper. - buildResolution populates both fields by converting the int64 epoch values from the registration response. - lookupCachedResolution treats an entry with a non-zero ClientSecretExpiresAt that has passed as a cache miss, so the singleflight body re-runs registerAndCache and overwrites the stale entry via the existing cache.Put. A Debug log attributes the refetch to client_secret_expires_at so operators can correlate the re-registration with the upstream's expiry rather than guessing. Tests: - TestBuildResolution_PopulatesRFC7591ExpiryFields covers all three shapes (both populated, expires_at omitted, both omitted) and that zero on the wire becomes the zero time.Time. - TestResolveDCRCredentials_RefetchesOnExpiredCachedSecret pins the cache-miss-on-expiry behaviour: an upstream that returns an already- expired secret causes back-to-back resolver calls to register twice. - TestResolveDCRCredentials_HonoursFutureExpiryAndZero pins the cache- hit path: future expiry and the zero-means-does-not-expire wire convention both serve from the cache without re-registering. Co-Authored-By: Claude Opus 4.7 (1M context) * Recover panics inside the DCR singleflight closure singleflight.Group re-panics the leader's panic in every follower, so without recovery a panic in registerAndCache (or anything it calls — the registration HTTP exchange, the cache.Put, etc.) would crash the leader goroutine and every concurrent follower for the same DCRKey with the same value. Net effect: a single bad upstream response could take out N goroutines instead of one error path. - The dcrFlight.Do closure now installs a defer/recover that converts a panic into a normal error. The recovered value is logged at slog.Error with a full debug.Stack() so the panic is not silently swallowed; the returned error wraps the recovered value so callers can react to it as a normal failure mode. - Doc comment on the singleflight call expanded to explain why the recover is necessary (the fan-out semantics of singleflight). Tests: - panickingPutDCRStore: a new test double whose Put panics with a configured value while Get returns a normal cache miss, so callers reach the singleflight closure and trigger the panic via cache.Put inside registerAndCache. - TestResolveDCRCredentials_RecoversPanicInsideSingleflight: spawns N=6 concurrent callers for the same DCRKey, each with its own defer/recover so an un-recovered panic is captured as a test failure rather than crashing the suite. Asserts every caller received an error containing the panic-marker string and the recovered value, and that none of them observed an actual panic. Co-Authored-By: Claude Opus 4.7 (1M context) * Tighten singleflight coalescing test to fail loudly on timing slip The existing assertion "registrationCalls == 1" is necessary but not sufficient: a goroutine that reached resolveDCRCredentials after the leader's cache.Put returned would short-circuit through lookupCachedResolution, take the cache hit, and still leave the count at 1. Under CI load the 50ms gate window was easy to miss, which would silently weaken what the test claims to cover. - Wrap the in-memory store in a countingStore decorator that records every Get that returned a hit. - Assert cache.hits.Load() == 0 after wg.Wait — any non-zero value means a late-arriver took the lookupCachedResolution short-circuit instead of joining the singleflight, and the coalescing path was not actually exercised. - Bump the gate window from 50ms to 250ms for headroom under CI load. The countingStore assertion turns any remaining timing slip into a loud failure rather than a silent regression. Co-Authored-By: Claude Opus 4.7 (1M context) * Consolidate validateResolveInputs tests into one table The previous TestResolveDCRCredentials_RequiresClientIDEmpty and TestResolveDCRCredentials_RequiresDCRConfig each exercised one branch of validateResolveInputs, leaving three uncovered: nil run-config, empty issuer, and nil credential store. Per .claude/rules/testing.md "Consolidation", folding into one table- driven test covers every branch in one place and shrinks duplicated setup. - Replace the two single-branch tests with TestResolveDCRCredentials_RejectsInvalidInputs, which iterates over all five branches and asserts the wrapped error message contains the expected substring drawn from validateResolveInputs's literals. Co-Authored-By: Claude Opus 4.7 (1M context) * Note in-memory DCR store is for tests / single-replica dev Reviewer asked us to confirm the framing and document it on the constructor. The unbounded-cache concern in .claude/rules/go-style.md "Resource Leaks" does not bite for this implementation because the key space is bounded by the operator-configured upstream count and because Phase 3 Redis is the production answer; the doc now states that explicitly so a future reader does not assume this is a production-grade store. Co-Authored-By: Claude Opus 4.7 (1M context) * Reject nil resolution in DCRCredentialStore.Put A nil resolution previously fell through as a silent no-op: the caller got a successful return, the next Get returned a miss, and there was no error trail to debug from. Per the constructor-validation rule in .claude/rules/go-style.md, fail loudly at the boundary. - inMemoryDCRCredentialStore.Put returns an explicit error when the resolution is nil, before taking the lock. - DCRCredentialStore.Put interface doc records the contract so future backends (e.g. the Phase 3 Redis store) behave consistently. - New TestInMemoryDCRCredentialStore_Put_RejectsNilResolution pins the rejection and asserts the rejected Put did not leave any partial entry behind. Co-Authored-By: Claude Opus 4.7 (1M context) * Disambiguate local vs upstream issuer in DCR resolver The resolveDCRCredentials doc said "issuer is the upstream authorization server's issuer identifier used both for discovery and for keying the cache." That was wrong on both counts: the upstream's issuer is recovered separately from rc.DCRConfig.DiscoveryURL via deriveExpectedIssuerFromDiscoveryURL, and the parameter actually names *this* auth server. An inline comment in registerAndCache already contradicted the public doc, and a future caller reading only the public doc would have produced (a) a wrong-origin default redirect URI under the upstream IdP and (b) a cache key that does not identify the auth-server context. Renaming the parameter and documenting the contract closes the trap. - resolveDCRCredentials: parameter renamed issuer → localIssuer; doc rewritten to spell out that it is *this* auth server's issuer, used to key the cache and default the redirect URI, and that the upstream's issuer is recovered separately. Same rename applied to validateResolveInputs, registerAndCache, lookupCachedResolution, chooseRegistrationScopes, and resolveUpstreamRedirectURI for internal consistency. - endpointsFromMetadata, synthesiseRegistrationEndpoint: parameter renamed issuer → upstreamIssuer (it is in fact the upstream's, recovered from the DiscoveryURL) so the local/upstream split is symmetric. - DCRKey.Issuer: doc clarifies the field carries *this* auth server's local issuer; two different local issuers registering against the same upstream are distinct OAuth clients and must not share cache entries. - Structured-log keys "issuer" → "local_issuer" everywhere the value is the local issuer, so operators can tell the two apart in logs too. Co-Authored-By: Claude Opus 4.7 (1M context) * Require explicit endpoints when DCR bypasses discovery When dcr_config.registration_endpoint is set, the resolver bypasses RFC 8414 / OIDC Discovery and therefore cannot populate authorization_endpoint or token_endpoint from server metadata. The operator-facing prose on DCRUpstreamConfig already says the run-config must supply both, but neither validator enforced it. The downstream effect was silent: dcrEndpoints came back with empty authorize/token URLs, applyExplicitEndpointOverrides only filled them from rc, and applyResolution only wrote when rc fields were empty — so a misconfigured run-config completed registration successfully and only broke at the first authorize or token-exchange call. - OAuth2UpstreamRunConfig.Validate now rejects a config that sets DCRConfig.RegistrationEndpoint without both AuthorizationEndpoint and TokenEndpoint, with an error message that names the field and explains the discovery-bypass rationale. - The discovery-flow path (DCRConfig.DiscoveryURL) is unaffected: metadata populates the endpoints there, so leaving them empty in the run-config remains valid. - Existing test case "DCRConfig with only registration_endpoint is valid" updated to also set authorize/token endpoints (the path it was claiming to cover); two new cases pin the rejection when each endpoint is missing; one new case pins that DiscoveryURL is still valid without explicit endpoints.

00:00:00 2001 From: reyortiz3 Date: Fri, 1 May 2026 10:35:26 -0400 Subject: [PATCH 084/291] Allow standalone Redis in auth server storage (#4994) * Allow standalone Redis in auth server: update validateConfig Add Addr field to RedisConfig for standalone mode (e.g., GCP Memorystore, AWS ElastiCache), making it mutually exclusive with SentinelConfig. Update validateConfig to enforce the mutual exclusion and require exactly one connection mode. Update NewRedisStorage to branch between redis.NewClient (standalone) and redis.NewFailoverClient (sentinel). Co-Authored-By: Claude Sonnet 4.6 * Allow standalone Redis in auth server: add Addr to RunConfig and update converter Co-Authored-By: Claude Sonnet 4.6 * Allow standalone Redis in auth server: update CRD RedisStorageConfig Add an Addr field for standalone Redis mode and make SentinelConfig optional. A CEL XValidation rule enforces that exactly one of addr (standalone) or sentinelConfig (Sentinel) is set. Regenerate deepcopy, CRD manifests, and API reference docs. Co-Authored-By: Claude Sonnet 4.6 * Allow standalone Redis in auth server: update operator buildStorageRunConfig Replace the Sentinel-only requirement with support for either a standalone addr or a SentinelConfig, matching the new RedisStorageConfig.Addr field added to the CRD in earlier tasks. Co-Authored-By: Claude Sonnet 4.6 * Fix review issues in standalone Redis implementation - Fix CEL XValidation rule Unicode curly quote bug in RedisStorageConfig (replaced U+201D right double quotation mark with ASCII single quotes) - Add mutual exclusivity guard when both addr and sentinelConfig are set in buildStorageRunConfig - Add test case covering the addr+sentinelConfig conflict error path - Update RedisStorage doc comment to describe both standalone and Sentinel modes - Use t.Cleanup instead of defer in withRedisStorage parallel test helper - Use non-default ACL username in TestNewRedisStorage_Standalone_WithMiniredis - Regenerate CRD manifests and API docs Co-Authored-By: Claude Sonnet 4.6 * Fix standalone Redis review issues: CEL rule, mutual-exclusivity guard, tests - Fix CEL XValidation rule: replace string literal comparison with size() > 0 to avoid gci formatter rewriting quote characters - Add mutual-exclusivity guard in buildStorageRunConfig for both addr AND sentinelConfig set - Add test case for "both addr and sentinelConfig set" error in buildStorageRunConfig - Fix doc comment on RedisStorage to mention both standalone and Sentinel modes - Switch withRedisStorage cleanup from defer to t.Cleanup for parallel test safety - Use non-default username in standalone miniredis test - Regenerate CRD manifests and API docs Co-Authored-By: Claude Sonnet 4.6 * Regenerate swagger docs to include addr field in RedisRunConfig Co-Authored-By: Claude Sonnet 4.6 * Allow empty username in Redis auth for managed services Redis services such as GCP Memorystore Basic/Standard HA and Azure Cache for Redis use password-only AUTH and do not expose ACL users. The previous implementation required a non-empty username, which forced go-redis to send AUTH and caused authentication failures on those tiers. When username is omitted, go-redis v9 sends HELLO with "default" as the username (falling back to legacy AUTH for servers that predate HELLO), which is the correct form for password-only managed Redis. - Remove the empty-username validation in storage.validateConfig - Skip username env var resolution in convertRedisACLConfig when UsernameEnvVar is empty, producing an empty ACLUserConfig.Username - Mark UsernameSecretRef optional in RedisACLUserConfig CRD type and only populate UsernameEnvVar in the RunConfig when the ref is present - Update docs to reflect standalone mode support, optional username, TLS CA cert guidance for managed services, and note that Redis Cluster mode (GCP Memorystore Cluster, ElastiCache Serverless) is not supported Co-Authored-By: Claude Sonnet 4.6 * Regenerate CRDs and reference docs for optional usernameSecretRef Runs task operator-manifests and task crdref-gen to pick up the optional-username changes: removes usernameSecretRef from the required list in MCPExternalAuthConfig and VirtualMCPServer CRDs, updates the field description, and refreshes crd-api.md accordingly.

This works well for single-instance deployments but does not support horizontal scaling since each replica has its own isolated state. Redis provides a shared storage backend that enables multiple auth server replicas to share OAuth 2.0 state (tokens, authorization codes, clients, and user data). **Key design decisions:** -- **Sentinel-only**: Only Redis Sentinel deployments are supported (not standalone or cluster mode). Sentinel provides automatic failover and high availability without the complexity of Redis Cluster. -- **ACL user authentication**: Only Redis ACL user authentication is supported.

Configure goconst to ignore test files and require 25+ occurrences before flagging, and suppress reporting in test/ and deploy/ paths; avoids touching test files while keeping the linter meaningful -

This allowed the first two blocks to pass while the final Expect saw the wrong phase. Combine all three checks into a single Eventually so the test only exits once the controller has reached a stable state where all conditions are simultaneously satisfied.

When set, the prefix is appended to the gateway URL when writing ANTHROPIC_BASE_URL in direct-mode tool configs (Claude Code, Codex). - Auto-probe: if the flag is omitted, issue a HEAD request to /anthropic/v1/messages; a 401 response (auth-reachable path) triggers automatic prefix selection. 404 or any error means no prefix. - Proxy-mode tools (Cursor, VS Code) are unaffected — they route through `thv llm proxy` and don't use ANTHROPIC_BASE_URL.

7d16db5037c47d2682723e48b87ac0d9971f4628 Mon Sep 17 00:00:00 2001 From: Yolanda Robla Mota Date: Tue, 5 May 2026 09:39:40 +0200 Subject: [PATCH 090/291] Automate Gemini CLI .env injection for LLM gateway proxy setup (#5175) thv llm setup --client gemini-cli now writes GEMINI_API_KEY and GOOGLE_GEMINI_BASE_URL to ~/.gemini/.env automatically instead of printing a manual-step note. thv llm teardown removes those entries. Adds a general-purpose env-file mechanism to clientAppConfig (LLMEnvFileKeys/RelPath/FileName) so any future client with the same constraint can use it without new plumbing. The mock LLM gateway now handles /v1beta/* paths so proxy routing tests can exercise the full Gemini CLI request path end-to-end.

This extends the jsonPointerGet-based assertion pattern (introduced in #5142) to all remaining tests in the file. - Replace raw-string `assert.Contains` with `jsonPointerGet` exact-path assertions in `TestConfigureLLMGateway_CreatesFile`, `_DeepNestedKey`, `_PreservesExistingKeys`, `_ProxyMode`, and the three TLS skip-verify tests - Replace `assert.NotContains` with `_, ok := jsonPointerGet(...); assert.False(t, ok)` in `TestRevertLLMGateway_RemovesKey` and the TLS / Gemini TLS tests - `assert.Contains` is kept where `jsonPointerGet` cannot help: JSONC comment preservation checks and non-string JSON values (e.g. the `permissions` object) Closes #5179 Co-authored-by: taskbot --- pkg/client/llm_gateway_test.go | 53 +++++++++++++++++++--------------- 1 file changed, 30 insertions(+),

00:00:00 2001 From: Jakub Hrozek Date: Tue, 5 May 2026 10:05:28 +0100 Subject: [PATCH 094/291] Preserve runconfig-checksum on pod template overrides (#5149) deploymentForMCPServer merged user-supplied PodTemplateMetadataOverrides.Annotations onto the wrong base map: it passed deploymentAnnotations (the Deployment-level overrides, typically empty) instead of deploymentTemplateAnnotations (which already had the runconfig-checksum stamped on it). Because ctrlutil.MergeAnnotations is "first-arg-wins on conflict", the checksum was silently dropped from the pod template and any Deployment-level annotations leaked onto pods. Two user-visible symptoms followed: 1. Proxy pods stopped rolling on RunConfig changes whenever PodTemplateMetadataOverrides.Annotations was set. Without the checksum on the pod template, Kubernetes had no signal to recreate pods, so telemetry / inline-OIDC / external- auth-ref edits landed in the ConfigMap on disk but never reached the running proxy. Vault Agent users were the canonical population affected, since vault.hashicorp.com/* keys live in this override field. 2. The drift-checker deploymentNeedsUpdate built the expected pod-template annotations correctly, so it disagreed with the constructor on every reconcile. The operator hot-looped on r.Update without converging. The fix flips one variable so the merge starts from deploymentTemplateAnnotations. Add three layers of test coverage in mcpserver_resource_overrides_test.go: - an expectedPodTemplateAnns column on the table-driven resource-overrides test so every case asserts on deployment.Spec.Template.Annotations - a focused regression test pinning the no-leakage contract (checksum survives, user override survives, no extras) - a parity test asserting deploymentNeedsUpdate reports no drift immediately after deploymentForMCPServer with the same checksum and overrides Why this is safe: - The comparator deploymentNeedsUpdate in the same file was already merging in this order, and the sibling controller MCPRemoteProxyReconciler.buildPodTemplateMetadata uses this exact pattern. The fix brings the buggy constructor in line with both. - Kubernetes convention treats Deployment-level and pod-template annotations as separate scopes; the CRD exposes them as separate user-facing fields (ProxyDeployment.Annotations vs ProxyDeployment.PodTemplateMetadataOverrides.Annotations). No documentation, example (including examples/operator/vault/mcpserver-github-with-vault.yaml), or test in this repository places sidecar-injection annotations at the deployment level, so no documented user is regressed. - MergeAnnotations keeps the first-argument map winning on conflict, so a user cannot accidentally overwrite the runconfig-checksum from their override map.

The resolved ClientSecret is overlaid on the built upstream.OAuth2Config after buildPureOAuth2Config (whose signature and body remain intentionally unchanged) so that RFC 7591-obtained credentials flow through the same execution path as file/env-resolved secrets. - Each UpstreamRunConfig element is shallow-copied and its OAuth2 sub-config is deep-copied before DCR resolution, preserving the caller's RunConfig.Upstreams slice per .claude/rules/go-style.md "Copy Before Mutating Caller Input". - resolveDCRCredentials emits structured logs: Debug on cache hit with dcr_age_days, an additional Warn when the cached registration exceeds dcrStaleAgeThreshold (90 days), and Error with a "step" attribute identifying which phase failed on every error path. - The /oauth/register handler upgrades its success log to Info with upstream, issuer, client_id, software_id, token_endpoint_auth_method, and scopes. SoftwareID is threaded through DCRRequest validation so incoming "software_id" is captured. A small helper guards against a nil embedded *fosite.Config (a legitimate test-only condition). - isTransientNetworkError's permanent-4xx branch now emits a Warn with a DCR remediation hint before returning false unchanged. The MonitoredTokenSource gains an optional SetUpstreamContext setter so the upstream and client_id fields can be threaded into the log without breaking the existing NewMonitoredTokenSource contract. - Integration tests exercise the full DCR boot path against a mock AS, verify the cache-hit short-circuit issues zero additional HTTP requests, and assert the caller's original RunConfig.Upstreams slice element is unchanged across both calls. Address authserver DCR review feedback Fixes from the CODE_REVIEW_ISSUES.md review of commit 71c4f436: Critical - Wire upstream/client_id into MonitoredTokenSource so the DCR remediation warning carries meaningful correlation fields. Promote the fields to constructor parameters (replacing SetUpstreamContext) to remove the unsynchronized writer and force callers to supply them at construction. - Runner populates the new fields from the RemoteAuthConfig, preferring the DCR-cached client_id over the statically configured one. High - /oauth/register handler drops the redundant upstream attribute that mirrored issuer, and omits issuer when empty rather than emitting a bare issuer="". - Resolver no longer logs each error branch and then returns; it now wraps failures in a DCRStepError and the boundary caller (buildUpstreamConfigs) emits a single slog.Error via LogDCRStepError. - The DCR-resolved ClientSecret is applied through a new applyResolutionToOAuth2Config helper paired with applyResolution, so the DCR application sites live side-by-side and future call sites cannot silently drop the secret. Medium - Remove the Type==OAuth2 guard that duplicated needsDCR's nil check. - Cap software_id to 256 characters and require printable ASCII in ValidateDCRRequest; expose MaxSoftwareIDLength. - Add TestNewEmbeddedAuthServer_DCRBoot to drive the full constructor and assert EmbeddedAuthServer.dcrStore is populated after boot. - Remove the nil-guard in Handler.issuer() and add TestHandler_issuer so a real wiring bug fails loudly instead of logging issuer="". - Sanitize error strings before logging to strip URL query parameters that could plausibly carry tokens in a future refactor. Preserve URL-trailing punctuation in DCR log sanitiser The query-stripping regex in sanitizeErrorForLog matches `[^\s"']+`, so a URL ending with sentence punctuation (`.`, `,`, `)`, `]`, etc.) pulls that punctuation into the URL match. url.Parse then absorbs it into the raw query, and the Strip + Reassemble step drops it along with the rest of the query — mangling the surrounding prose. Split the trailing run of terminal punctuation off the match before parsing, and re-append it verbatim after the query is stripped. URL matches without a query are returned untouched so the pass is idempotent for URLs that are already clean. New test cases cover commas, periods, closing parens, mixed runs, and a Go http.Client-style quoted URL. Co-Authored-By: Claude Opus 4.7 (1M context) * Bound upstream DCR /register error body before logging A misbehaving or malicious authorization server could echo arbitrary content into the upstream's /register error response. handleHTTPResponse read that body via io.ReadAll with no LimitReader, then embedded it verbatim in the returned error — which downstream callers log. Cap the read at 8 KiB (far larger than any conformant RFC 7591 error response) so operator log volume cannot be inflated by a non-conformant upstream. Addresses stacklok/toolhive#5044 review finding F2 (HIGH). Co-Authored-By: Claude Opus 4.7 (1M context) * Mirror CIMD precedence in remoteAuthLogContext The doc comment claimed remoteAuthLogContext mirrored the precedence of remote.Handler.resolveClientCredentials, but the implementation skipped the CachedCIMDClientID check entirely. For CIMD-authenticated workloads the new DCR remediation Warn would have reported a stale or empty client_id rather than the CIMD URL actually being sent on token refresh, defeating the operator-correlation the field exists for. Restore the documented precedence (CachedCIMDClientID > CachedClientID > ClientID) and add a TestRemoteAuthLogContext case covering the CIMD-wins path. Addresses stacklok/toolhive#5044 review findings F3 (HIGH) and F26 (MEDIUM, closed by the new test case). Co-Authored-By: Claude Opus 4.7 (1M context) * Hoist DCR remediation Warn out of network-error classifier isTransientNetworkError previously emitted the cached-DCR-client remediation Warn from inside its classifier on every permanent 4xx. A tight Token() loop hitting the same condition would spam the same record on every call before the workload's Unauthenticated status propagated. The same branch also fired for non-DCR workloads, which saw a remediation telling them to "delete cached credentials" they never had. Strip the side effect from the classifier and emit the Warn from markAsUnauthenticated, which already gates the close-monitoring transition through stopOnce. The Warn now fires at most once per state transition, is suppressed when no client_id context is available, and reads honestly about the variability ("if this workload uses cached DCR or CIMD credentials they may be stale"). Addresses stacklok/toolhive#5044 review finding F5 (MEDIUM). Co-Authored-By: Claude Opus 4.7 (1M context) * Validate handler config eagerly and demote DCR success log Two related polish items in the authserver handlers package: NewHandler did not validate that AuthorizationServerConfig (or its embedded *fosite.Config) was non-nil. issuer() reached into the config at request time, so a misconfigured caller would panic deep inside an HTTP handler instead of failing at startup. Add the nil check to the constructor and simplify issuer() to rely on the constructor invariant. Pin the new invariant with TestNewHandler_ErrorsOnNilConfig. The /oauth/register success log was promoted to Info even though the operation is neither long-running nor exceptional. Demote back to Debug; an audit-log path is the right home for the audit signal if that becomes a requirement. Addresses stacklok/toolhive#5044 review findings F6 and F7. Co-Authored-By: Claude Opus 4.7 (1M context) * Tighten DCR resolver internals and clarify cache lifetimes Bundles ten review-feedback items in pkg/authserver/runner; each addresses internal-API hygiene or doc-comment drift in the DCR resolver, no behaviour change for callers. Sanitizer hardening (F1, F19, F18, F23): sanitizeErrorForLog now strips userinfo and fragment in addition to the query, since either can carry credentials or tokens (https://user:pass@host, implicit-flow #access_token=...). queryStrippingPattern matches http/https case-insensitively per RFC 3986 §3.1 so HTTPS://... cannot escape sanitisation. trimURLTrailingPunctuation switches to strings.IndexByte to match the ASCII-only terminator set without the rune-decoding overhead. Test cases added for each. Resolver error API (F4, F13, F20): the dcrStepRegister panic-recovery branch no longer emits a duplicate slog.Error; the captured stack travels with the wrapped *dcrStepError to the boundary log so a single panic produces a single record. DCRStepError / LogDCRStepError lowercased to dcrStepError / logDCRStepError since no caller lives outside the package. logDCRStepError now no-ops on nil err so the unknown-step branch cannot fire on a missing failure. Resolution helpers (F11, F12, F25): applyResolution renamed to consumeResolution to communicate that it is a one-shot state transition (clearing DCRConfig is unconditional), not an idempotent defaulting step. The applyResolutionToOAuth2Config doc now states the paired-call invariant explicitly without referencing a specific test. Lifecycle docs (F21, F22): the per-instance dcrStore vs. process-wide dcrFlight asymmetry is now stated on both sides, and EmbeddedAuthServer.Close documents the future-Close hook for a backend with handles. Inline rules-file rationale (F24): production comments no longer cite .claude/rules/... by path; the principle is inlined. Addresses stacklok/toolhive#5044 review findings F1, F4, F11, F12, F13, F18, F19, F20, F21, F22, F23, F24, F25. Co-Authored-By: Claude Opus 4.7 (1M context) * Tighten DCR remediation hint and drain capped error body Three follow-up items from review: isPermanentTokenEndpointError used to treat every non-5xx RetrieveError as permanent, which meant the DCR remediation Warn fired on transient back-pressure (408 Request Timeout, 429 Too Many Requests). Narrow the classifier to an explicit 400 / 401 / 403 allowlist so the "delete the cached credentials and restart" hint fires only on responses where stale cached client credentials are a plausible cause. Retry behaviour is unaffected — the retry decision is gated entirely by isTransientNetworkError, which already returns false for the whole RetrieveError branch. handleHTTPResponse in pkg/oauthproto/dcr.go now drains the response body after the LimitReader-bounded ReadAll. Without this, an upstream returning more than 8 KiB on /register error left the connection mid- stream when the deferred Close fired, preventing TCP connection reuse. Mirrors what the non-JSON content-type branch a few lines down already does. remoteAuthLogContext moved out of pkg/runner into pkg/auth/remote as *Config.LogContext(), collocating it with resolveClientCredentials so the cached-CIMD > cached-DCR > static precedence has one home. Adding a fourth cached field in future updates both call sites in one place. Tests moved to pkg/auth/remote/config_test.go. Addresses stacklok/toolhive#5044 review #4212656411 comments 3174540081, 3174540082, and 3174540086.

This is the library-standard surface for non-2xx token endpoint responses, and aligns the error shape with the JWT Bearer grant that will share helpers in pkg/oauth. Behavior changes: - validateResponseStatus takes *http.Response so it can attach the full response to the returned error and parse the body as RFC 6749 §5.2 best-effort. - When the body is non-conformant (no "error" field, e.g. a proxy HTML 5xx), the raw body is logged at debug level and cleared from the returned error. This prevents oauth2.RetrieveError.Error() from interpolating arbitrary upstream content (HTML, hostnames, stack traces) into wrapped error strings — same two-tier pattern used by formatOAuth2Error in pkg/authserver. - parseTokenExchangeResponse wraps json.Unmarshal failures with %w. The error type change is isolated from code movement so a future bisect can distinguish "error shape regressed" from "plumbing regressed". * Always clear RetrieveError.Body in tokenexchange The previous commit cleared the body only when the response was non-conformant (no RFC 6749 §5.2 "error" field), on the theory that a structured-error body is bounded and harmless. PR review pointed out the asymmetry, and the simpler answer is to clear Body in both branches: - The structured fields (ErrorCode, ErrorDescription, ErrorURI) are already extracted onto *oauth2.RetrieveError, so callers using errors.As lose nothing. - Full body content is preserved in slog.Debug for ops, regardless of which branch is taken. - No caller in this repo reads retrieveErr.Body for any non-debug purpose (verified by grep on .RetrieveError\b). - Removes a special case future maintainers would have to re-derive. This matches Ory Hydra, which never surfaces raw upstream error bodies through its public error type — see the JWKS fetcher in fosite/client_authentication_jwks_strategy.go and the token-hook client in oauth2/token_hook.go, both of which discard the body and return only the upstream status code on non-2xx responses. --- pkg/auth/tokenexchange/exchange.go | 76 ++++++++++++------------- pkg/auth/tokenexchange/exchange_test.go | 59 +++++++++++-------- 2 files changed, 69 insertions(+), 66 deletions(-) diff --git a/pkg/auth/tokenexchange/exchange.go b/pkg/auth/tokenexchange/exchange.go index 430a4dff9b..b6a8e3fb68 100644 --- a/pkg/auth/tokenexchange/exchange.go +++ b/pkg/auth/tokenexchange/exchange.go @@ -7,7 +7,6 @@ package tokenexchange import ( "context" "encoding/json" - "errors" "fmt" "io" "log/slog" @@ -67,34 +66,6 @@ func NormalizeTokenType(tokenType string) (string, error) { } } -// oAuthError represents an OAuth 2.0 error response as defined in RFC 6749 Section 5.2. -type oAuthError struct { - Error string `json:"error"` - ErrorDescription string `json:"error_description,omitempty"` - ErrorURI string `json:"error_uri,omitempty"` - StatusCode int `json:"-"` -} - -func (e *oAuthError) String() string { - if e.ErrorURI != "" { - return fmt.Sprintf("OAuth error %q (status %d): see %s", e.Error, e.StatusCode, e.ErrorURI) - } - return fmt.Sprintf("OAuth error %q (status %d)", e.Error, e.StatusCode) -} - -// parseOAuthError attempts to parse an OAuth error response from the given response body. -func parseOAuthError(statusCode int, body []byte) *oAuthError { - var oauthErr oAuthError - if err := json.Unmarshal(body, &oauthErr); err != nil { - return nil - } - if oauthErr.Error == "" { - return nil - } - oauthErr.StatusCode = statusCode - return &oauthErr -} - // defaultHTTPClient is the default HTTP client used for token exchange requests. var defaultHTTPClient = &http.Client{ Timeout: defaultHTTPTimeout, @@ -502,7 +473,7 @@ func executeTokenExchangeRequest(client *http.Client, req *http.Request) ([]byte return nil, fmt.Errorf("failed to read token exchange response: %w", err) } - if err := validateResponseStatus(resp.StatusCode, body); err != nil { + if err := validateResponseStatus(resp, body); err != nil { return nil, err } @@ -510,21 +481,44 @@ func executeTokenExchangeRequest(client *http.Client, req *http.Request) ([]byte } // validateResponseStatus checks the HTTP status code and returns an error if not successful. -func validateResponseStatus(statusCode int, body []byte) error { - if statusCode >= 200 && statusCode <= 299 { +// On non-2xx responses it extracts RFC 6749 §5.2 fields (error, error_description, error_uri) +// onto the structured fields of the returned *oauth2.RetrieveError.

Map iteration order is randomized by the runtime spec, so the resulting []EnvVar ordering changed between calls even when the contents were identical. Kubernetes hashes env list order into the pod template hash, so each reorder triggered a no-op StatefulSet rollout. In a deployed MCPServer this surfaced as repeated pod recreations after operator pod restarts, with secondary fallout: during the bridge recreation window the proxy runner's /health pinger blocks for its 5s timeout, racing the kubelet liveness probe (also 5s by default) and killing the proxy container. Each restart triggered another reconcile which re-iterated the env map and produced yet another order. Sort the keys before iterating so the env list is stable. Add a regression test that runs DeployWorkload 10+ times and asserts the StatefulSet's mcp container env order matches a fixed sorted slice; without the fix it fails reliably within a few iterations. Same class of bug as #4783 (vMCP discovery) and #3450 (vMCP server ordering), on the MCPServer code path. * Extract env var conversion to fix gocyclo complexity DeployWorkload exceeded gocyclo's 15-branch threshold after the deterministic env var sorting was added. Move the conversion into a dedicated helper to keep DeployWorkload under the limit.

This broke OAuth for servers like Common Room that don't support RFC 8707. Remove the automatic URL-to-resource fallback in both buildRemoteAuthConfigFromMetadata and createRequestToRemoteAuthConfig, keeping only user-provided and metadata-provided resource values. Fixes: #5203 Co-Authored-By: Claude Opus 4.6 (1M context) * test(api): add resource indicator tests for createRequestToRemoteAuthConfig Verify that resource is NOT auto-derived from URL when not explicitly set, and that an explicitly provided resource is preserved verbatim. These tests guard against re-introducing the removed fallback derivation.

Inline orphaned variable in createRequestToRemoteAuthConfig. The resource parameter is now only set when explicitly provided by the user or registry metadata, matching the behavior of the direct CLI path which gates on --resource-url.

Add DCRUpstreamConfig CRD type (discoveryUrl, registrationEndpoint, initialAccessTokenRef, softwareId, softwareStatement) and a new dcrConfig field on OAuth2UpstreamConfig so Kubernetes users can configure RFC 7591 Dynamic Client Registration on upstream providers. - Make OAuth2UpstreamConfig.clientId optional and add CEL validation requiring exactly one of clientId or dcrConfig, and exactly one of discoveryUrl or registrationEndpoint inside dcrConfig. Mirror the checks at runtime via validateOAuth2DCRConfig for defense-in-depth. - Wire the conversion in controllerutil/authserver.go so DCRConfig is mapped onto authserver.DCRUpstreamConfig. InitialAccessTokenRef is resolved to an env var (TOOLHIVE_UPSTREAM_DCR_INITIAL_ACCESS_TOKEN_*) populated from the referenced Secret, mirroring the ClientSecretRef pattern. Extract small helpers for env-var generation to keep cyclomatic complexity within lint limits. - Regenerate zz_generated.deepcopy.go, CRD YAML manifests, and CRD API reference docs. - Add table-driven validation tests covering DCR+ClientID conflict, both endpoints set, neither endpoint set, valid single-endpoint cases, and neither-auth configuration. Add conversion tests covering DCR discoveryUrl/registrationEndpoint paths and initial-access-token env var wiring. Co-Authored-By: Claude Opus 4.7 (1M context) Address code review feedback Fixed issues from code review of the DCR CRD surface commit: - CRITICAL: CEL markers contained a Unicode smart quote (U+201D) that gofmt's doc-comment formatter reintroduced on every lint-fix. Rewrote both markers to use CEL's size(...) > 0 idiom instead of `!= ''`, which sidesteps the typographic normalization entirely and keeps regeneration idempotent. Verified no U+2018-U+201F characters remain in source or CRDs. - HIGH: buildUpstreamRunConfig now calls the exported mcpv1beta1.ValidateOAuth2DCRConfig before producing a RunConfig, so malformed ClientID/DCRConfig pairs that bypass admission fail at reconcile time rather than at authserver startup. Error propagation threaded through BuildAuthServerRunConfig; split OIDC and OAuth2 branches into helpers to stay under the gocyclo limit. - HIGH: Added table case exercising validateUpstreamProvider rejection of an OIDC-typed provider whose OAuth2Config carries a DCRConfig. - MEDIUM: Added kubebuilder CEL XValidation on UpstreamProviderConfig enforcing oidcConfig/oauth2Config mutual exclusivity paired to the declared type, closing the silent-pod-failure YAML-apply gap. - MEDIUM: Added MaxLength=255 to SoftwareID and MaxLength=4096 to SoftwareStatement to prevent unbounded input from inflating CRs beyond etcd object limits. - MEDIUM: Pinned the "neither ClientID nor DCRConfig" error assertion to the scoped `oauth2Config:` prefix; added a regression case exercising the non-DCR OAuth2 path (ClientID only, DCRConfig nil); added a new TestBuildAuthServerRunConfig_InvalidDCR suite covering all four invalid DCR/ClientID pairings at the conversion layer. - MEDIUM: Renamed UpstreamDCRInitialAccessTokenEnvVar to UpstreamDCRInitialAccessTokenEnvVarPrefix and expanded the godoc on both prefix constants to show the resolved _ form. All task lint/lint-fix/license-check pass; regenerated CRDs and deepcopy are idempotent; affected unit tests pass. Co-Authored-By: Claude Opus 4.7 (1M context) Address iteration-2 review feedback Polish items raised in the second review pass: - MEDIUM: Trim duplicate upstream name from reconcile-time DCR validation errors. Added scopedFieldPath() helper in cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go so ValidateOAuth2DCRConfig prepends a dotted prefix only when one is given, and the conversion call site now passes an empty prefix so BuildAuthServerRunConfig's outer "upstream %q: %w" wrap is the only mention of the upstream name. Strengthened TestBuildAuthServerRunConfig_InvalidDCR to assert the upstream name appears exactly once in the error string. - MEDIUM: Make the UpstreamProviderConfig CEL rule fail closed for unrecognized future provider types. Restructured the rule from a binary discriminator into a chain of equality checks ending in an explicit `false`, and updated the message to "type must be 'oidc' or 'oauth2'; ...". Added a contributor-facing doc comment reminding future authors to extend both the rule and validateUpstreamProvider when adding a new UpstreamProviderType. - MEDIUM: Refresh the godoc on extractUpstreamSecretRefs to describe the actual invariants that hold post-CEL: OIDC providers can only return a clientSecretRef; OAuth2 providers can return both independently; other (currently unreachable) types return nil/nil. Cross-linked to the CEL rule and noted that BuildAuthServerRunConfig is the reconcile-time backstop callers should not rely on this helper to enforce. Regenerated CRD YAMLs and crd-api.md prose. task lint, lint-fix, license-check, and the affected unit tests pass; regeneration is idempotent.

Regenerated CRDs (operator-manifests) and docs/operator/crd-api.md (crd-ref-docs) so propagated text picks up the doc-comment corrections. Co-Authored-By: Claude Opus 4.7 (1M context) * Refactor ValidateOAuth2DCRConfig and OAuth2 conversion helper Addresses stacklok/toolhive#5069 review comments: - F4 MEDIUM mcpexternalauthconfig_types.go (3174398117): drop the unenforced `prefix` parameter on ValidateOAuth2DCRConfig and the single-use scopedFieldPath helper. The validator now always emits scoped to "oauth2Config[.dcrConfig[.field]]"; callers wrap with their own outer scope (validateUpstreamProvider wraps with "upstreamProviders[i]: %w"; buildOAuth2UpstreamRunConfig relies on the existing outer "upstream %q: %w" wrap in BuildAuthServerRunConfig). A future caller passing the upstream name can no longer accidentally double-prefix. - F8 LOW authserver.go (3174398131): make buildOAuth2UpstreamRunConfig parallel to buildOIDCUpstreamRunConfig — drop the redundant `provider` and `*upstreamSecretBinding` parameters in favor of a `cfg *OAuth2UpstreamConfig` plus two scalar env-var names. Removes the unenforced provider/binding aliasing invariant. - F13 LOW authserver.go (3174398155): drop named returns from extractUpstreamSecretRefs to match the unnamed-returns convention used by sibling helpers. Co-Authored-By: Claude Opus 4.7 (1M context) * Strengthen DCR env-var assertions and consolidate redundant tests Addresses stacklok/toolhive#5069 review comments: - F5 MEDIUM authserver_test.go (3174398120): assert SecretKeyRef.Key alongside Name in TestGenerateAuthServerEnvVars; the existing rows used distinct keys ("client-secret" vs "token") but the assertion ignored them, so a refactor that crossed the keys would have passed silently. - F14 LOW authserver_test.go (3174398158): replace the now-invalid ClientSecretRef-plus-DCRConfig case (rejected by the F3 CEL/Go rule) with a multi-upstream DCR row exercising two OAuth2 providers, each with their own InitialAccessTokenRef. A regression that hashed names instead of sanitize-and-uppercase no longer passes silently. - F16 LOW authserver_test.go (3174398170): reduce TestBuildAuthServerRunConfig_InvalidDCR to a single representative case. ValidateOAuth2DCRConfig itself is exhaustively covered in the v1beta1 types_test table; this test now only pins the conversion-layer responsibility (outer `upstream %q:` wrap, single occurrence of the upstream name) which a single case fully exercises.

No behavior change. * Resolve local skill builds by name when tag differs A local skill build tagged with something other than its declared skill name (e.g. thv skill build --tag v0.0.1) was not findable via POST /api/v1beta/skills with a plain name + version body: install-by-name did a literal tag lookup against the local OCI store, so the only resolvable handle was the OCI tag string. Callers got 404 "not found in local store or registry" even though the build was visible in GET /skills/builds. Extend resolveFromLocalStore so that when the direct tag lookup misses, or when a caller-supplied version disagrees with the direct match, it walks the local-build-marked tags for one whose declared skill name matches. The version filter accepts either the artifact's cfg.Version or the local store tag, mirroring the OCI-name install path that already treats version as the tag and matching the GET /skills/builds output where many artifacts carry a tag like "v0.0.1" with an empty SKILL.md version. With multiple matches, prefer the build whose tag equals the skill name; otherwise return 409 Conflict listing each candidate's tag and version. Add table-driven cases covering: scan resolves by skill name when tag differs, version matches the local store tag (the user-facing reproducer), version filter narrows multiple matches, version mismatch falls through to registry, direct version mismatch falls through to scan, ambiguous matches return 409, and non-skill local-build-marked tags are ignored. Tighten the test runner so wantErr is also asserted when wantCode is set. --- pkg/skills/skillsvc/install_oci.go | 210 +++++++++++++++++++++-- pkg/skills/skillsvc/install_oci_test.go | 213 ++++++++++++++++++++++++ 2 files changed, 413 insertions(+), 10 deletions(-) diff --git a/pkg/skills/skillsvc/install_oci.go b/pkg/skills/skillsvc/install_oci.go index fb7249be6b..f77be955df 100644 --- a/pkg/skills/skillsvc/install_oci.go +++ b/pkg/skills/skillsvc/install_oci.go @@ -13,8 +13,10 @@ import ( "time" nameref "github.com/google/go-containerregistry/pkg/name" + "github.com/opencontainers/go-digest" "github.com/stacklok/toolhive-core/httperr" + ociskills "github.com/stacklok/toolhive-core/oci/skills" "github.com/stacklok/toolhive/pkg/skills" ) @@ -113,15 +115,38 @@ func (s *service) installFromOCI( return s.installWithExtraction(ctx, opts, scope) } -// resolveFromLocalStore attempts to resolve a skill name as a tag in the local -// OCI store.

6 May 2026 22:55:58 +0100 Subject: [PATCH 105/291] Add identity extractor for OAuth2 token responses (#5200) Some OAuth2 upstream providers do not expose a usable userinfo endpoint and instead place user identity directly in the token endpoint response. Two response shapes appear in practice: - Identity as side-attributes alongside the tokens, e.g. Snowflake's `username`, Slack's `authed_user.id`, Shopify's `associated_user.{id,email,first_name}`. - Identity claims embedded inside a JWT-shaped access token, e.g. Auth0, Azure AD, Keycloak, Cognito. Introduce a pure helper that reads operator-supplied gjson dot-notation paths from the raw token-response body to extract subject, name, and email. Register a custom gjson modifier `@upstreamjwt` so paths can pipe through a JWT payload decode step (e.g. "access_token|@upstreamjwt|sub"). The modifier base64url-decodes the JWT payload without verifying the signature; trust comes from the TLS-authenticated channel to the AS, the same trust model as the existing userinfo path. Signed-token flows remain handled by the existing OIDC provider type. Modifier registration is exported and explicit (RegisterModifiers) so callers control when the process-global gjson state mutates. The helper is consumed by the embedded auth server's OAuth2 upstream provider in a later commit; nothing in this commit calls it yet. Type guard restricts the subject to scalar string or number values to avoid silently returning a JSON blob as the user's identity. Numeric subjects are returned via the raw JSON token rather than gjson's float64 formatting to preserve integer precision beyond 2^53. Error messages never include any portion of the body.

update CEL rule to require exactly one of the three modes - Regenerate deepcopy, CRD YAML, and Helm chart templates - Add unit tests for all new validation and happy-path code paths Closes #5010 Co-Authored-By: Claude Sonnet 4.6 * Simplify Redis Cluster mode to addr + clusterMode bool ClusterConfig{Addrs []string} was a misleading abstraction: GCP Memorystore Cluster and AWS ElastiCache cluster mode both expose a single discovery endpoint, so the slice always held exactly one address and was redundant with the existing Addr field. Replace ClusterConfig with a ClusterMode bool flag that is set alongside the existing Addr field. go-redis NewClusterClient still receives the single endpoint as []string{addr} and auto-discovers the full cluster topology from there.

The client side correctly limited the response body via io.LimitReader to MaxResponseSize, but the server side missed the symmetric limit on inbound requests, so the webhook package would buffer arbitrarily large bodies into memory. Wrap r.Body with http.MaxBytesReader at MaxRequestSize (1 MB, symmetric to MaxResponseSize) and return HTTP 413 with a JSON-RPC error envelope when the limit is exceeded. Reject the read before any forwarding. Note: this is the webhook-layer cap. mcp.ParsingMiddleware sits earlier in the proxy chain and currently reads the body unbounded; capping inbound bodies at the MCP parsing layer is tracked separately and is the load-bearing fix against upstream DoS. This change still bounds the webhook package's own re-read buffer and lays the symmetry groundwork.

Every thv serve startup runs discovery.Discover to detect a previous instance via the discovery URL, which routes through HTTPClientForURL, so without an npipe arm two concurrent thv processes on Windows could not see each other and would silently overwrite the discovery file. Add an npipe:// arm whose transport DialContext goes through winio.DialPipeContext, plus a ParseNamedPipeURL helper that strips the scheme and validates the remaining segment (non-empty, no path separators, no ".."). Split the actual dialer into pipe_windows.go (winio-backed) and pipe_other.go (returns a clear "only supported on Windows" error), so non-Windows builds do not import winio and a misconfigured discovery URL surfaces a useful message instead of an obscure dial syscall failure. go-winio is already a direct dependency at v0.6.2, so no go.mod change is required. * Add Windows named-pipe support to API listener setupUnixSocket assumed the address was a filesystem path -- it ran os.Stat, os.Remove, os.MkdirAll, and os.Chmod around net.Listen("unix", ...). None of that applies to a Windows named pipe (\.\pipe\thv-api), and net.Listen("unix", ...) is not a substitute since named pipes are a different kernel object. As a result, toolhive-studio could not run thv with a pipe address on Windows. Split setupUnixSocket and cleanupUnixSocket into per-platform files via build tags, mirroring pkg/container/docker/sdk. On Windows, branch on the \.\pipe\ prefix and use winio.ListenPipe with InputBufferSize and OutputBufferSize at 64 KiB; MessageMode stays at byte-stream because HTTP requires byte framing. Skip stat/remove/mkdir/chmod for pipes since they are not files; keep stat/remove/mkdir for the AF_UNIX fallback (Win10 1803+) but drop chmod because POSIX modes do not apply on Windows. ListenURL emits npipe:// for pipe addresses so the discovery file URL stays unambiguous. createListener labels the listener as "Windows named pipe" and rejects pipe addresses on non-Windows up front, rather than creating a literal-backslash file via AF_UNIX. * Test npipe URL parsing and discovery health TestParseNamedPipeURL covers the success case plus every rejection branch (missing scheme, wrong scheme, empty name, forward slash, backslash, ".."). A non-Windows guard test asserts CheckHealth("npipe://...") surfaces a clear "Windows" error rather than a misleading dial syscall failure. The Windows-only health_windows_test.go spins up a winio listener with an http.Server.Serve goroutine and asserts CheckHealth("npipe://", expectedNonce) succeeds with a matching nonce, plus a not-found case that expects "health check failed". An atomic counter disambiguates parallel pipe names, since the Windows pipe namespace is global. * Test API listener split and pipe URL forms Cover the per-platform refactor of setupUnixSocket. On all platforms, assert socketURL emits unix:// for filesystem addresses and that isNamedPipeAddress detects \.\pipe\ prefixes. On Windows, additionally assert socketURL emits npipe://, that setupUnixSocket against a unique pipe path returns a winio listener that accepts a winio dial within a 2 s timeout (proving the listener is wired to the named-pipe namespace, not AF_UNIX), and that cleanupUnixSocket no-ops for pipe addresses without panicking. Tests are split via build tags so the Windows test file is only compiled on GOOS=windows and pulls in winio there. * Tighten Windows named-pipe handling per review Address aponcedeleonch's review on PR #5201: - Update --socket help to mention named pipes and regen CLI docs. - Promote namedPipePrefix to discovery.NamedPipePrefix as the canonical definition; pkg/api re-aliases it locally so listener and dialer cannot drift. - Make isNamedPipeAddress case-insensitive via strings.EqualFold; the Windows pipe namespace is case-insensitive at the kernel layer, so \\.\Pipe\foo must not silently fall through to AF_UNIX. - Collapse stat-then-remove into a single os.Remove that tolerates fs.ErrNotExist on both POSIX and the Windows AF_UNIX fallback. - Close the listener and remove the socket file when Chmod fails, rather than leaking a bound AF_UNIX listener. - Replace stdruntime.GOOS with a per-platform supportsNamedPipe() helper, dropping the runtime-package alias and its collision with pkg/container/runtime. - Rename socket_other.{go,_test.go} to socket_unix.{go,_test.go} to match the client_unix/client_windows convention used by pkg/container/docker/sdk. - Add TestCreateListener_NamedPipe_Unsupported to round out the listener-side reject coverage on non-Windows builds.

Define the persisted DCRCredentials value type and the storage-level DCRCredentialStore interface in pkg/authserver/storage/, and ship the in-process memory implementation that single-replica deployments and unit tests use. The Redis backend (sub-issue 2) and the wiring change (sub-issue 3) build on this. DCRKey consolidation: chose option (a) from the issue — DCRKey and its ScopesHash constructor move to pkg/authserver/storage/ so any future backend hashes keys identically. The runner package keeps a package-local type alias (type DCRKey = storage.DCRKey) and a var binding for scopesHash so existing call sites compile unchanged; the canonical form has a single source of truth. DCRCredentials carries ClientSecretExpiresAt so the Redis backend can drive a SetEX TTL without re-touching the value type or regenerating mocks. The interface contract documents this as SHOULD honor when backend-supported; MemoryStorage retains entries verbatim for the process lifetime. StoreDCRCredentials rejects nil creds and zero-valued Key.Issuer or Key.RedirectURI with fosite.ErrInvalidRequest, matching the StoreUpstreamTokens validation pattern. Stats reports dcrCredentials count for parity with the other in-memory maps. The runner-side DCRCredentialStore (Get/Put *DCRResolution) is left in place as the thin adapter sub-issue 3 will swap. This sub-issue lands the new storage-level interface, MemoryStorage implementation, and regenerated mock without touching the wire-up. DCR credentials are intentionally excluded from cleanupExpired: RFC 7591 client registrations are long-lived and the authoritative expiry signal is client_secret_expires_at, which the Redis backend will honor as a SetEX TTL. * Rename runner-side DCR cache to dcrResolutionCache Eliminates the post-merge name collision between runner.DCRCredentialStore and storage.DCRCredentialStore. The two interfaces serve different purposes (runtime resolution cache vs persistent credential store), and the same-name collision in sibling packages forces every reader and grep search to mentally disambiguate during the Phase 3 migration. Renaming the runner-side interface to lowercase dcrResolutionCache keeps the canonical DCRCredentialStore name reserved for the storage package, which is where the future Redis backend will plug in. The rename is internal to pkg/authserver/runner — no external callers exist. Renamed symbols: - DCRCredentialStore -> dcrResolutionCache - inMemoryDCRCredentialStore -> inMemoryDCRResolutionCache - NewInMemoryDCRCredentialStore -> newInMemoryDCRResolutionCache - TestInMemoryDCRCredentialStore_* -> TestInMemoryDCRResolutionCache_* Addresses stacklok/toolhive#5186 review F2 (HIGH, score 9): naming collision with runner.DCRCredentialStore. * Inline storage.ScopesHash at runner call sites Replace `var scopesHash = storage.ScopesHash` with direct calls to storage.ScopesHash. The variable was a mutable runtime binding (any package code could reassign it, no compile-time guard) and an extra indirection layer for tooling and refactors. Qualifying call sites makes the storage dependency visible and matches the type-alias strategy already used for DCRKey in dcr_store.go. Addresses stacklok/toolhive#5186 review F3 (MEDIUM, score 8): mutable runtime binding, not a true alias. * Tighten StoreDCRCredentials validation Reject empty Key.ScopesHash, ClientID, AuthorizationEndpoint, and TokenEndpoint with fosite.ErrInvalidRequest, matching the broader "required field" contract documented on the DCRCredentials struct. The previous validation only checked Key.Issuer and Key.RedirectURI, which silently accepted partial registrations: a caller forgetting to populate ScopesHash would Store under the empty-string slot while a sibling that did compute ScopesHash(nil) (a non-empty digest) would land on a different cache cell, splitting one logical record across two slots. Likewise, accepting an empty ClientID, AuthorizationEndpoint, or TokenEndpoint would Store a working-looking record that fails downstream at the upstream's token endpoint with no audit trail. ClientSecret is left permissive because RFC 7591 §2 public clients (token_endpoint_auth_method = "none") legitimately have no secret. Tests: replaced the three-case nil/issuer/redirect_uri table with a seven-case table that constructs a fully valid DCRCredentials and isolates one missing field per subtest; updated the existing RoundTrip / DistinctKeys / Overwrite / DefensiveCopy / StoreCopyIsolates / ExcludedFromCleanupExpired tests to populate the newly-required fields so they exercise the success path under the tightened contract. Addresses stacklok/toolhive#5186 review F4 (MEDIUM, score 9): validation narrower than the documented contract. * Correct DCR-cache bounding-claim comments The previous comments asserted the cache is "bounded by the operator-configured upstream count". This holds only when (Issuer, RedirectURI, ScopesHash) is invariant per upstream over the process lifetime. ScopesHash changes whenever the operator widens or narrows the scope set on MCPServer.Spec.OAuthConfig.Scopes, or when an upstream's RFC 8414 scopes_supported rotates and the resolver re-derives the scope set. Each distinct ScopesHash produces a fresh entry; nothing evicts the prior one (cleanupExpired deliberately skips this map), so in a long-lived process with rotating scope sets growth is upstream count × distinct-scope-sets-ever-registered, not upstream count alone. Each retained entry holds a ClientSecret, so this is also a (slow) sensitive-data accumulation. The Redis backend's SetEX TTL mitigates this in production. Updated parallel comments at memory.go:97 and runner/dcr_store.go:61 to state the actual bound and the production mitigation. Addresses stacklok/toolhive#5186 review F5 (MEDIUM, score 8): "bounded by upstream count" claim incorrect when scopes change. * Document why DCRKey is embedded in DCRCredentials The DCRCredentialStore interface takes (ctx, creds) on Store rather than the (ctx, key, value) shape used by sibling methods on Storage. The asymmetry is intentional — embedding DCRKey in DCRCredentials.Key makes the persisted blob self-describing, so a Redis SCAN, an admin dump, or a cross-replica reconciliation path can identify a record's logical cache slot from the value alone — but it diverges from the package's "key + value" convention enough that future readers will ask why. Add a "Why the key is embedded" section to the interface doc that states the rationale and points at the Memory backend's validation contract for the populate-Key requirement. Addresses stacklok/toolhive#5186 review F6 (MEDIUM, score 7): signature/naming inconsistent with sibling Storage methods. The reviewer offered two paths — rename to GetDCR/StoreDCR + drop Key, or document the rationale. Documenting was selected because the embedded-Key shape is load-bearing for the Phase 3 Redis backend. * Add concurrent-access test for DCR Store/Get methods The existing TestMemoryStorage_ConcurrentAccess fan-out covers authcodes, tokens, and clients but not the new DCRCredentialStore methods, and every other DCR test runs single-goroutine. A regression that dropped the RWMutex or returned an internal pointer instead of a defensive copy would not be caught by the suite under -race. Add a dedicated TestMemoryStorage_DCRCredentials_ConcurrentAccess that fans out 16 workers × 200 ops, alternating Store / Get against an overlapping key space (lock must serialise writes) and a disjoint key space (reads must always hit). Bounded by a 10s fail-fast deadline so a deadlock regression surfaces with a clear message rather than the global test timeout. Mirrors the runner-side TestInMemoryDCRResolutionCache_ConcurrentAccess pattern. Addresses stacklok/toolhive#5186 review F7 (LOW-MEDIUM, score 7): missing concurrent-access test for new DCR Store/Get methods. --- pkg/authserver/runner/dcr.go | 45 +- pkg/authserver/runner/dcr_store.go | 90 ++-- pkg/authserver/runner/dcr_store_test.go | 119 ++--- pkg/authserver/runner/dcr_test.go | 57 +-- pkg/authserver/runner/embeddedauthserver.go | 8 +- .../runner/embeddedauthserver_test.go | 8 +- pkg/authserver/storage/memory.go | 103 +++++ pkg/authserver/storage/memory_test.go | 410 ++++++++++++++++++ pkg/authserver/storage/mocks/mock_storage.go | 55 ++- pkg/authserver/storage/types.go | 180 +++++++- 10 files changed, 858 insertions(+), 217 deletions(-) diff --git a/pkg/authserver/runner/dcr.go b/pkg/authserver/runner/dcr.go index 092af89911..a850e5fa65 100644 --- a/pkg/authserver/runner/dcr.go +++ b/pkg/authserver/runner/dcr.go @@ -5,8 +5,6 @@ package runner import ( "context" - "crypto/sha256" - "encoding/hex" "errors" "fmt" "log/slog" @@ -15,13 +13,13 @@ import ( "regexp" "runtime/debug" "slices" - "sort" "strings" "time" "golang.org/x/sync/singleflight" "github.com/stacklok/toolhive/pkg/authserver" + "github.com/stacklok/toolhive/pkg/authserver/storage" "github.com/stacklok/toolhive/pkg/authserver/upstream" "github.com/stacklok/toolhive/pkg/networking" "github.com/stacklok/toolhive/pkg/oauthproto" @@ -73,7 +71,7 @@ var authMethodPreference = []string{ // successful Dynamic Client Registration, together with the endpoints the // upstream advertises so the caller need not re-discover them. // -// The struct is the unit of storage in DCRCredentialStore and the unit of +// The struct is the unit of storage in dcrResolutionCache and the unit of // application via consumeResolution. type DCRResolution struct { // ClientID is the RFC 7591 "client_id" returned by the authorization @@ -229,35 +227,6 @@ func applyResolutionToOAuth2Config(cfg *upstream.OAuth2Config, res *DCRResolutio cfg.ClientSecret = res.ClientSecret } -// scopesHash returns the SHA-256 hex digest of the canonical scope set. -// -// Canonicalisation: -// 1.

Changes for issue #5197: - Add PrimaryUpstreamProvider to InlineAuthzConfig (shared type, vMCP-only in practice, mirroring the SubjectProviderName precedent on the token- exchange and AWS-STS strategies). - Switch the converter from unconditional first-upstream binding to an explicit-then-fallback resolution; both branches normalize through authserver.ResolveUpstreamName. - Reject the spec with AuthServerConfigValidated=False (AuthzUpstreamUnknown) when the explicit name does not match any declared upstream — Cedar would otherwise deny every request at runtime. - Suppress the AuthzUpstreamSelectionWarning advisory when the user has set the field explicitly; the auto-selection it warns about is no longer happening. - Extend converter and validator tests; regenerate CRD YAMLs and API docs. Existing manifests without the new field keep current behavior — the fallback branch is unchanged for that path. * Address code review feedback Fixed issues from code review: - MEDIUM: Reject explicit primaryUpstreamProvider when no embedded auth server is configured. The early-return direct-IdP branch in validateAuthzUpstreamAvailable now checks for a non-empty explicit name first and returns SpecValidationError with ConditionReasonAuthzUpstreamUnknown when set — closing the silent misconfiguration where the converter would forward an unresolvable name into Cedar config at runtime. - MEDIUM: Update the converter block comment so it accurately describes both rejection paths (mismatch with declared upstreams AND explicit name without an embedded AS), keeping the comment synchronized with the validator's behavior per the go-style.md rule. - MEDIUM: Replace the misleading "is normalized via ResolveUpstreamName" converter test with a case that actually exercises normalization (upstream Name:"" resolving to "default", user pinning to "default"). Removes redundancy with the single-upstream-honored case and matches the test's claimed assertion. - MEDIUM: Add validator test case for explicit primaryUpstreamProvider with no embedded auth server, locking the new rejection in. * Harden primaryUpstreamProvider contract on shared types Addresses stacklok/toolhive#5199 review comments: - MEDIUM cmd/thv-operator/api/v1beta1/mcpserver_types.go:785 (F1): surface advisory condition AuthzPrimaryUpstreamProviderIgnored on MCPServer/MCPRemoteProxy reconcilers when primaryUpstreamProvider is set; the field has no embedded auth server to honor it. - MEDIUM cmd/thv-operator/controllers/virtualmcpserver_controller.go:562 (F3): move the explicit-provider lookup to AuthzConfigRef. ExplicitPrimaryUpstreamProvider() so the validator and the converter share one accessor. - LOW mcpserver_types.go:784 (F11): add kubebuilder Pattern matching the upstream-name regex from pkg/authserver/config.go so kubectl apply rejects malformed values up-front. - LOW mcpserver_types.go:783 (F12): doc the inline-only constraint and point at the configMap TODO in vmcpconfig/converter.go. - LOW virtualmcpserver_controller.go:562 (F13): renamed via the move in F3 — the new method has the cleaner name. * Refactor authz upstream validator Addresses stacklok/toolhive#5199 review comments: - MEDIUM cmd/thv-operator/controllers/virtualmcpserver_controller.go:628 (F2): extract rejectAuthzAdmission to dedupe the boilerplate (clear advisory + log + Phase=Failed + condition + ObservedGeneration + return *SpecValidationError) used by the two new authz rejection branches. - MEDIUM virtualmcpserver_controller.go:569 (F6): expand the function doc to describe the new explicit-primaryUpstreamProvider rejections alongside the original behaviors. - LOW virtualmcpserver_controller.go:687 (F8): replace the matched-bool/break loop with slices.ContainsFunc. The "no upstreams declared" branch (line 635) is intentionally not folded into the helper because it returns a plain error (causing requeue) rather than *SpecValidationError (no requeue) — preserving the existing semantics for that branch. * Tighten authz converter and split rejection condition reason Addresses stacklok/toolhive#5199 review comments: - MEDIUM cmd/thv-operator/pkg/vmcpconfig/converter.go:213 (F4): add a defensive cross-check so Convert refuses to produce an unresolvable PrimaryUpstreamProvider — even if invoked outside the reconcile flow (CLI dry-run, webhook, test harness). Errors when the explicit name has no embedded auth server, or doesn't match any declared upstream. Validator remains the primary user-facing fail-loud point. - LOW converter.go:199 (F9): retract the stale "no embedded AS leaves PrimaryUpstreamProvider empty" claim and describe the post-PR contract precisely. - LOW cmd/thv-operator/api/v1beta1/virtualmcpserver_types.go:407 (F10): introduce ConditionReasonAuthzPrimaryProviderRequiresAuthServer for the no-AS case and keep ConditionReasonAuthzUpstreamUnknown for the mismatch case, so dashboards/alerts can route the two misconfigurations separately. Updated the validator branch and the matching test to use the new reason. Updated converter test "explicit primary provider without auth server is forwarded" → "is rejected" to reflect the new fail-closed contract, and added a sibling test for the upstream-mismatch case. * Add tests for configMap fall-through and recovery; link configMap TODOs Addresses stacklok/toolhive#5199 review comments: - MEDIUM cmd/thv-operator/pkg/vmcpconfig/converter.go:210 (F5): - File tracking issue stacklok/toolhive#5208 covering both configMap TODOs (policy load + primaryUpstreamProvider override) and reference it from the comments. - Add validator test TestVirtualMCPServerValidateAuthzUpstreamAvailable_ConfigMapFallThrough that pins the documented inline-only contract: configMap-sourced authz never trips the new admission rejections, the multi-upstream advisory still fires, and configMap users get auto-selection of the first upstream. - MEDIUM cmd/thv-operator/controllers/virtualmcpserver_controller_test.go :3718 (F7): add TestVirtualMCPServerValidateAuthzUpstreamAvailable_ClearsStaleAuthzUnknown table with both new failure reasons. Mirrors the production reconcile order (validateAuthServerConfig → validateAuthzUpstreamAvailable) to lock in the recoverability contract: a corrected spec transitions AuthServerConfigValidated back to True and the stale rejection reason does not survive. * Tighten primaryUpstreamProvider markers and user-facing doc Addresses stacklok/toolhive#5199 review comments: - cmd/thv-operator/api/v1beta1/mcpserver_types.go (3200963688): add MinLength=1 and MaxLength=63 markers to match the upstream-name field constraints on UpstreamProviderConfig.Name. The CRD schema was previously accepting arbitrarily long values before the controller's existence check rejected them. - mcpserver_types.go (3200963706): rewrite the kubebuilder doc-comment to drop "TODO" + internal source-tree path, both of which propagate verbatim to kubectl explain and crd-api.md. Reference issue #5208 for the configMap follow-up instead. The internal TODO(#5208) tag in pkg/vmcpconfig/converter.go is the right place for the engineering reference. * Harmonize authz validator helpers and fold no-upstreams branch Addresses stacklok/toolhive#5199 review comments: - cmd/thv-operator/controllers/mcpserver_controller.go (3200963674): drop the inline r.Status().Update from validateAuthzPrimaryUpstreamProviderIgnored so its shape matches the MCPRemoteProxy sibling. Mirror the sibling's "caller persists status" doc comment so the deferred-flush contract is documented. The terminal updateMCPServerStatus call in Reconcile picks up the in-place condition mutation. - cmd/thv-operator/controllers/virtualmcpserver_controller.go (3200963682): the comment claiming the no-upstreams branch preserves requeue semantics by returning a plain error was wrong. runAuthValidations discards the error and returns false; both *SpecValidationError and stderrors.New produce the same outcome through this call chain. handleSpecValidationError is only called from ensureVmcpConfigConfigMap (a different path). Migrate the branch to rejectAuthzAdmission to remove the inconsistency. * Document primaryUpstreamProvider in vMCP prose docs Addresses stacklok/toolhive#5199 review body (doc-strategy question): - docs/operator/virtualmcpserver-api.md: expand the authzConfig field description to document the full InlineAuthzConfig/ConfigMapAuthzRef shape, including primaryUpstreamProvider with its precondition (multiple upstreamProviders configured) and rejection behavior. - docs/operator/virtualmcpserver-kubernetes-guide.md: add a brief callout in the Authorization Policy Errors section explaining when to pin a specific upstream IDP via primaryUpstreamProvider. --- .../api/v1beta1/mcpserver_types.go | 42 +++ .../api/v1beta1/virtualmcpserver_types.go | 14 + .../controllers/mcpremoteproxy_controller.go | 28 ++ .../controllers/mcpserver_controller.go | 28 ++ .../virtualmcpserver_controller.go | 119 +++++++-- .../virtualmcpserver_controller_test.go | 240 ++++++++++++++++++ cmd/thv-operator/pkg/vmcpconfig/converter.go | 41 ++- .../pkg/vmcpconfig/converter_test.go | 91 ++++++- ...oolhive.stacklok.dev_mcpremoteproxies.yaml | 34 +++ .../toolhive.stacklok.dev_mcpservers.yaml | 34 +++ ...olhive.stacklok.dev_virtualmcpservers.yaml | 34 +++ ...oolhive.stacklok.dev_mcpremoteproxies.yaml | 34 +++ .../toolhive.stacklok.dev_mcpservers.yaml | 34 +++ ...olhive.stacklok.dev_virtualmcpservers.yaml | 34 +++ docs/operator/crd-api.md | 1 + docs/operator/virtualmcpserver-api.md | 11 + .../virtualmcpserver-kubernetes-guide.md | 14 + 17 files changed, 802 insertions(+), 31 deletions(-) diff --git a/cmd/thv-operator/api/v1beta1/mcpserver_types.go b/cmd/thv-operator/api/v1beta1/mcpserver_types.go index 200874bc95..d86a20751c 100644 --- a/cmd/thv-operator/api/v1beta1/mcpserver_types.go +++ b/cmd/thv-operator/api/v1beta1/mcpserver_types.go @@ -89,6 +89,12 @@ const ( // ConditionTypeWebhookConfigValidated indicates whether the WebhookConfig is valid ConditionTypeWebhookConfigValidated = "WebhookConfigValidated" + + // ConditionTypeAuthzPrimaryUpstreamProviderIgnored is an advisory condition set + // when spec.authzConfig.inline.primaryUpstreamProvider is non-empty on a CR type + // that has no embedded auth server (MCPServer / MCPRemoteProxy).

Every grant now picks up the same process-wide transport and connection pool. - Redaction: delete the local redactedPlaceholder and emptyPlaceholder constants; the three String() methods (exchangeRequest, response, clientAuthentication) now call oauthproto.Redact(value), which replaces four hand-rolled "if empty/else redacted" branches with one expression each. - Pre-existing annotation cleanup: four //nolint:gosec // G117 directives on sensitive struct-tag fields (AccessToken, RefreshToken, ClientSecret x2) were suppressing a rule gosec does not actually flag. Delete them per the go-style.md rule against //nolint directives that do not suppress a confirmed false positive. middleware.go had one //nolint:gosec // G706 in the same state; same treatment. - Test hygiene: convert every defer server.Close() in exchange_test.go (22 sites) to t.Cleanup(server.Close). Every affected site runs t.Parallel either directly or via subtests; .claude/rules/testing.md calls out defer as a foot-gun there because the parent test function can return before parallel subtests finish, closing the server prematurely. maxResponseBodySize stays local with a TODO referencing the follow-up that replaces executeTokenExchangeRequest with oauthproto.DoTokenRequest, at which point the local constant disappears. createTokenExchangeRequest, executeTokenExchangeRequest, parseTokenExchangeResponse are untouched in this commit for the same reason: isolating the HTTP-client swap from the request-plumbing rewrite makes a future bisect point at one concern at a time. --- pkg/auth/tokenexchange/exchange.go | 79 ++++++++----------------- pkg/auth/tokenexchange/exchange_test.go | 44 +++++++------- pkg/auth/tokenexchange/middleware.go | 5 +- 3 files changed, 48 insertions(+), 80 deletions(-) diff --git a/pkg/auth/tokenexchange/exchange.go b/pkg/auth/tokenexchange/exchange.go index b6a8e3fb68..75c422863b 100644 --- a/pkg/auth/tokenexchange/exchange.go +++ b/pkg/auth/tokenexchange/exchange.go @@ -21,19 +21,13 @@ import ( "github.com/stacklok/toolhive/pkg/oauthproto" ) -const ( - // defaultHTTPTimeout is the timeout for HTTP requests - defaultHTTPTimeout = 30 * time.Second - - // maxResponseBodySize is the maximum size for reading response bodies (1 MB) - maxResponseBodySize = 1 << 20 - - // redactedPlaceholder is used to redact sensitive values in string representations - redactedPlaceholder = "[REDACTED]" - - // emptyPlaceholder is used to indicate empty/missing values in string representations - emptyPlaceholder = "" -) +// maxResponseBodySize bounds io.LimitReader in executeTokenExchangeRequest so +// a pathological server cannot exhaust memory.

That assumption holds for POST (which carries the JSON-RPC body) but not for valid Streamable HTTP lifecycle traffic: GET opens an SSE stream, DELETE terminates a session. Operator-driven sessions and keepalives produced one WARN per pod every ~30s, drowning real signals. Gate the warning on r.Method == POST so misconfiguration on the JSON-RPC path still surfaces while expected non-JSON-RPC requests stay quiet. Recording of mcp.server.operation.duration is unchanged.

The round-trip is exercised by new tests on both platforms. HTTPClientForURL now dispatches on url.Parse + switch u.Scheme, which gives case-insensitive scheme matching (NPIPE://x routes the same as npipe://x) for free and matches what the http arm already does via ValidateLoopbackURL. ParseNamedPipeURL gains explicit checks that net/url alone cannot do: a 247-character cap (CreateNamedPipeW's lpName limit minus the \\.\pipe\ prefix), the legacy reserved Windows device names (CON, NUL, COM1-9, LPT1-9, ...), and a positive charset of [A-Za-z0-9._-]+. Names are lowercased via strings.ToLower because the pipe namespace is case-insensitive at the kernel layer; the old strings.Contains(name, "..") guard is removed because it rejected legitimate names like my..api. ParseUnixSocketPath rejects URLs with non-empty authority, query, fragment, or userinfo; it also strips the synthetic leading slash that url.URL inserts in front of Windows drive letters so unix:///C:%5Cpath%5Cthv.sock round-trips back to C:\path\thv.sock. Co-authored-by: Cursor * Fix Windows AF_UNIX socket URL round-trip socketURL on Windows for AF_UNIX paths emitted unix://C:%5Cpath%5Cthv.sock (two slashes) because url.URL.String() only inserts the host/path slash when Host != "". url.Parse then mis-reads the drive letter as host:port and returns "invalid port :%5Cpath%5Cthv.sock", breaking the producer/consumer contract that the rest of this PR establishes. Force the leading slash on Path so String() emits the three-slash form (unix:///C:%5Cpath%5Cthv.sock), which url.Parse accepts and which ParseUnixSocketPath already handles by stripping the synthetic slash before the drive letter. Add TestSocketURL_RoundTrip_AFUnix as a parallel to the existing named-pipe round-trip so future regressions on the Windows AF_UNIX side fail closed in CI rather than only being caught by reading the test fixture row. Addresses review on #5215.

Both fields are +optional with omitempty, so when a user submits a sentinel-only config the fields are absent from the validated object and CEL aborts with "no such key: addr" / "no such key: clusterMode" before the rule's own logic runs, rejecting configurations the rules were meant to allow. Wrap each scalar access in has(...) so the rules see absent fields as "unset" rather than failing evaluation. Truth tables for sentinel-only, standalone, cluster, both-set, and neither-set are unchanged. Regenerate operator manifests and CRD reference docs. * Add envtest regression test for RedisStorageConfig CEL rules Cover the six relevant cases of the addr / sentinelConfig / clusterMode truth table by submitting MCPExternalAuthConfigs to the envtest apiserver. Three are expected to admit (sentinel-only, standalone, cluster), three are expected to reject (neither set, both set, clusterMode without addr). The sentinel-only case mirrors the github-mcp-demo config that surfaced this bug. With the previous unguarded rules the apiserver returned 422 with "no such key: addr"; with the has()-guarded rules the case admits cleanly. Tests live in the existing mcp-external-auth integration suite so they pick up the suite_test.go envtest bootstrap (CRDs loaded from the generated chart, real apiserver enforcing CEL). --- .../v1beta1/mcpexternalauthconfig_types.go | 4 +- .../redis_storage_validation_test.go | 155 ++++++++++++++++++ ...e.stacklok.dev_mcpexternalauthconfigs.yaml | 10 +- ...olhive.stacklok.dev_virtualmcpservers.yaml | 10 +- ...e.stacklok.dev_mcpexternalauthconfigs.yaml | 10 +- ...olhive.stacklok.dev_virtualmcpservers.yaml | 10 +- 6 files changed, 181 insertions(+), 18 deletions(-) create mode 100644 cmd/thv-operator/test-integration/mcp-external-auth/redis_storage_validation_test.go diff --git a/cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go b/cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go index 32e83ebde0..5716fe83b1 100644 --- a/cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go +++ b/cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go @@ -664,8 +664,8 @@ type AuthServerStorageConfig struct { // addr points to a Redis Cluster discovery endpoint (GCP Memorystore Cluster, // AWS ElastiCache cluster mode enabled). // -// +kubebuilder:validation:XValidation:rule="(self.addr.size() > 0) != has(self.sentinelConfig)",message="exactly one of addr or sentinelConfig must be set" -// +kubebuilder:validation:XValidation:rule="!self.clusterMode || self.addr.size() > 0",message="clusterMode requires addr to be set" +// +kubebuilder:validation:XValidation:rule="(has(self.addr) && self.addr.size() > 0) != has(self.sentinelConfig)",message="exactly one of addr or sentinelConfig must be set" +// +kubebuilder:validation:XValidation:rule="!(has(self.clusterMode) && self.clusterMode) || (has(self.addr) && self.addr.size() > 0)",message="clusterMode requires addr to be set" // //nolint:lll // CEL validation rules exceed line length limit type RedisStorageConfig struct { diff --git a/cmd/thv-operator/test-integration/mcp-external-auth/redis_storage_validation_test.go b/cmd/thv-operator/test-integration/mcp-external-auth/redis_storage_validation_test.go new file mode 100644 index 0000000000..39d9cb1623 --- /dev/null +++ b/cmd/thv-operator/test-integration/mcp-external-auth/redis_storage_validation_test.go @@ -0,0 +1,155 @@ +// SPDX-FileCopyrightText: Copyright 2025 Stacklok, Inc. +// SPDX-License-Identifier: Apache-2.0 + +package controllers + +import ( + "fmt" + + .

None of these reproduce live bugs today; they pin invariants the named-pipe path implicitly relies on so a future change can't silently break them. TestWriteReadServerInfo_NamedPipe (cross-platform) closes the producer/consumer loop for the discovery file: an npipe:// URL written by socketURL must survive WriteServerInfo + ReadServerInfo without being mangled. The individual emit/parse pieces have their own tests; this one pins the seam. TestSetupUnixSocket_NamedPipe_FirstInstanceWins (Windows-only) asserts that two ListenPipe calls on the same name fail the second time. winio sets FILE_FLAG_FIRST_PIPE_INSTANCE so that two thv processes cannot bind the same pipe and race for traffic; if a future winio bump silently relaxed that, this test catches it before the discovery layer does in production. TestCheckHealth_NamedPipe_HungServerCancelsOnContext (Windows-only) covers the StateUnhealthy path: a peer that accepts connections but never responds must not wedge CheckHealth past the caller's context deadline. The existing success and not-found tests don't exercise this case. Co-authored-by: Cursor * Fix t.Cleanup race in hung-peer test TestCheckHealth_NamedPipe_HungServerCancelsOnContext registered t.Cleanup from inside the Accept loop goroutine. t.Cleanup is documented to be called from the test goroutine; a registration that lands after the test body returns can panic with "Log in goroutine after Test has completed" or be silently dropped. The test happened to work because the dial CheckHealth makes accepts before the test body returns, but correctness was load-bearing on that timing. Pre-register a single t.Cleanup from the test body that closes every accepted conn under a mutex, and have the goroutine append to that slice instead of touching t. Listener cleanup runs in LIFO order before the conn-close, which unblocks the goroutine's Accept first so the slice is stable by the time we close it. Drop the dead "if second != nil { Close }" branch in TestSetupUnixSocket_NamedPipe_FirstInstanceWins: setupUnixSocket returns (nil, err) on the named-pipe failure path, so the guard can never be entered. Replace with a comment so the next reader does not re-introduce it. Addresses review on #5216.

Each one was followed directly by withIntegrationStorage(t, ...), whose own t.Parallel() panicked with "t.Parallel called multiple times" on the same *testing.T. - MEDIUM types.go (review body): drop the "future sub-issue" framing from the DCRCredentials Lifetime section, the ClientSecretExpiresAt field doc, and the DCRCredentialStore interface doc now that RedisStorage exists. Also correct the "Redis SetEX" wording to "SET with a duration" in three places — go-redis emits SET ...

Phase 2 left two parallel DCR stores: a runner-side in-memory map in dcr_store.go and the storage-level interface added in sub-issue 1. This collapses the runner-side implementation into a thin storageBackedStore adapter that delegates to storage.DCRCredentialStore, leaving exactly one persistence implementation per backend (storage.MemoryStorage and storage.RedisStorage). NewInMemoryDCRCredentialStore is preserved as a test helper that wraps storage.NewMemoryStorage so existing resolver tests compile unchanged; the standalone inMemoryDCRCredentialStore type and its map / RWMutex are deleted. buildPureOAuth2Config is unchanged — the wiring change swaps the implementation passed to the resolver, not the call shape. Add TestEmbeddedAuthServer_DCRSurvivesRestart in embeddedauthserver_test.go (next to TestNewEmbeddedAuthServer_DCRBoot) covering the durable-restart case: boot, close, rebuild against the same storage.MemoryStorage instance, assert the second resolve makes zero AS requests. The integration_test.go file under pkg/authserver would otherwise be the natural home, but it is in package authserver and importing runner from there would cycle (runner already imports authserver); the test docstring records this constraint. * Address code review feedback Fixed issues from code review of #5185 wiring change: - HIGH: Storage backend leaked on NewEmbeddedAuthServer error paths. Split the constructor into a public NewEmbeddedAuthServer that calls createStorage and an unexported newEmbeddedAuthServerWithStorage that owns the cleanup contract via a deferred Close gated on a named return error. Verified by TestNewEmbeddedAuthServer_ClosesStorageOnError using a closeTrackingStorage wrapper. - MEDIUM: Comment claimed interface embedding that did not exist. Embed storage.DCRCredentialStore in the storage.Storage interface instead, promoting the runtime type assertion to a compile-time guarantee (the AC's explicitly preferred outcome). The dead error branch and its outdated comment are gone; mocks regenerated via task gen. - MEDIUM: Test placement deviated from AC instruction. Moved TestEmbeddedAuthServer_DCRSurvivesRestart out of the runner package and into a new pkg/authserver/integration_dcr_restart_test.go in package authserver_test, so the test lives next to the other pkg/authserver integration tests without inducing the runner -> authserver import cycle. Added a small public DCRStore() accessor on EmbeddedAuthServer mirroring existing IDPTokenStorage / UpstreamTokenRefresher accessors. - MEDIUM: Durable-restart not exercised end-to-end. Strengthened the restart test to go through NewEmbeddedAuthServer for the first boot (full constructor path with DCR), capture the storage via the new DCRStore() accessor, and assert the DCR row survives the first server's Close. The full "boot, close, boot again, observe zero /register" scenario remains a documented gap (the production Redis path requires Sentinel which miniredis does not speak); the gap and the conditions under which it can be closed are recorded in the test docstring per the review's accept-the-gap branch. * Tighten DCR secret-reach surface Addresses stacklok/toolhive#5196 review comments: - MEDIUM types.go (3203565433) F6: Storage no longer embeds DCRCredentialStore. The embed promoted GetDCRCredentials / StoreDCRCredentials onto every Storage consumer (handlers, registration, session, etc.), broadening the surface that can read raw client_secret and registration_access_token. The compile-time guarantee is preserved by the per-backend var _ DCRCredentialStore = (*MemoryStorage)(nil) / (*RedisStorage)(nil) checks; the runner and authserver constructors now obtain the DCR-capable handle via an explicit type assertion at the boundary, fail-loud if a future backend omits DCR. - MEDIUM embeddedauthserver.go (3203565453) F10: DCRStore() delegates through e.server.DCRStore() instead of holding a redundant e.dcrStore field. The Server interface now exposes DCRStore() with a SECURITY + lifecycle doc noting the returned handle surfaces raw secrets and is bound to Server.Close. Eliminates the drift window between EmbeddedAuthServer and the underlying authserver if the server ever swaps backends. * Fix test hygiene: cleanup, naming, restart honesty Addresses stacklok/toolhive#5196 review comments: - MEDIUM dcr_store.go (3203565416) F1: replace newInMemoryDCRResolutionCache (which leaked a MemoryStorage cleanupLoop goroutine on every call) with a test-only newMemoryDCRStore in dcr_testhelpers_test.go that takes *testing.T and registers t.Cleanup(stor.Close). Updates ~32 call sites across dcr_test.go, dcr_store_test.go, and embeddedauthserver_test.go. - MEDIUM dcr_store_test.go (3203565423) F3: rename test functions from TestInMemoryDCRResolutionCache_* to TestStorageBackedStore_* so the suite names match the type they actually exercise (the deleted inMemoryDCRResolutionCache type no longer exists). - MEDIUM dcr_store.go (3203565426) F4: dropped the production-marketing paragraphs from the helper's docstring (production code in NewEmbeddedAuthServer no longer reaches it). The new docstring on newMemoryDCRStore states the test-only purpose and the cleanup contract directly. - MEDIUM integration_dcr_restart_test.go (3203565429) F5: rename TestEmbeddedAuthServer_DCRSurvivesRestart -> TestEmbeddedAuthServer_DCRStorePersistsAcrossClose, and refactor to read credentials BEFORE Close. The test no longer silently depends on MemoryStorage's undocumented post-Close readability. Tightened the 44-line docstring to scope it to what is exercisable today and a pointer to the deferred follow-up. - LOW integration_dcr_restart_test.go (3203565449) F9: added "DO NOT COPY THIS A THIRD TIME" tripwire on both newMockUpstreamAS (authserver_test) and newMockAuthorizationServer (runner) directing the next caller to extract the helper to a shared pkg/authserver/internal/testhelpers package before duplicating it. * Add converter round-trip coverage and sanitize cleanup log Addresses stacklok/toolhive#5196 review comments: - MEDIUM dcr_store.go (3203565436) F7: added TestResolutionCredentialsRoundTrip pinning the field-by-field contract between resolutionToCredentials and credentialsToResolution (preserved, dropped, key-recovered, nil-shortcircuit). Added MUST-update-both-converters comments on the DCRResolution struct in dcr.go and the DCRCredentials struct in storage/types.go so a future contributor adding a field to either type sees the converter obligation at the struct definition rather than only at the converters. Documented the ProviderName asymmetry: the field is storage-only ("debug/audit only" per its own docstring) and is intentionally left unpopulated by the runner; the test asserts that invariant so any future threading is paired with the assertion update. - MEDIUM embeddedauthserver.go (3203565446) F8: route both closeErr and retErr in the deferred-cleanup slog.Warn through sanitizeErrorForLog so a wrapped DCR failure whose error chain inlines an upstream /register response body cannot leak userinfo, query, or fragment components into operator logs. Renamed the "original_error" key to "cause" to match the package-wide vocabulary. Added TestNewEmbeddedAuthServer_DeferredCleanupSanitizesLog which captures the Warn record by swapping slog.Default() and asserts both that literal secret markers are scrubbed and that host components survive for operator correlation. * Move DCR restart test back into runner package Drops the package authserver_test workaround introduced to break the runner -> authserver import cycle that blocked extending pkg/authserver/integration_test.go. The test's actual subject is the runner-side DCR-store wiring (it goes through runner.NewEmbeddedAuthServer and asserts on runner.EmbeddedAuthServer.DCRStore()), so the runner package is the natural home and matches the location of its sibling TestNewEmbeddedAuthServer_DCRBoot / _ClosesStorageOnError tests. The runner-package newMockAuthorizationServer helper replaces the duplicate newMockUpstreamAS the cross-package placement forced; the "DO NOT COPY THIS A THIRD TIME" tripwire on it is dropped now that the duplication is gone. --- pkg/authserver/runner/dcr.go | 10 + pkg/authserver/runner/dcr_store.go | 174 +++++----- pkg/authserver/runner/dcr_store_test.go | 204 +++++++++-- pkg/authserver/runner/dcr_test.go | 46 +-- pkg/authserver/runner/dcr_testhelpers_test.go | 28 ++ pkg/authserver/runner/embeddedauthserver.go | 125 +++++-- .../runner/embeddedauthserver_test.go | 321 +++++++++++++++++- pkg/authserver/server.go | 17 + pkg/authserver/server_impl.go | 30 +- pkg/authserver/server_test.go | 16 +- pkg/authserver/storage/types.go | 25 ++ 11 files changed, 819 insertions(+), 177 deletions(-) create mode 100644 pkg/authserver/runner/dcr_testhelpers_test.go diff --git a/pkg/authserver/runner/dcr.go b/pkg/authserver/runner/dcr.go index a850e5fa65..6dde6158e0 100644 --- a/pkg/authserver/runner/dcr.go +++ b/pkg/authserver/runner/dcr.go @@ -73,6 +73,16 @@ var authMethodPreference = []string{ // // The struct is the unit of storage in dcrResolutionCache and the unit of // application via consumeResolution. +// +// MUST update both converters (resolutionToCredentials and +// credentialsToResolution in dcr_store.go) when adding, renaming, or +// removing a field here.

The only existing safety nets — code review and end-to-end tests — do not scale. Add a reusable reflection-based field walker and a bidirectional drift test pattern. The pattern requires every leaf JSON field on either side of a CRD/runtime boundary to be either explicitly mapped to the other side or explicitly declared as intentionally unmapped, with a justification string. Adding a field to either type without classifying it fails the test with a clear action-required message. Apply the pattern to MCPTelemetryConfig <-> telemetry.Config as the first real-world exercise. The drift test passes against the current codebase and surfaced one previously-undocumented leaf (openTelemetry.caBundleRef.configMapRef.optional) which is now explicitly declared. Co-Authored-By: Claude Opus 4.7 (1M context) * Address review and lint on drift detection walker Fix lint failures from CI: rename reflect.Ptr to reflect.Pointer, suppress exhaustive on the kind switch with rationale, and tag the ,inline json fixtures as a known revive false positive. Replace the explicit leafTypes allowlist with a json.Marshaler interface check. Every entry in the previous map shared one property — a custom MarshalJSON whose output bears no relation to the Go field layout — so asking the type how it serializes is more general than maintaining a hand-rolled list of K8s and project types. The walker is now self-maintaining for any future custom-marshaled type. Address reviewer findings on telemetry_drift_test.go: - delete dead sortedKeys helper and its misleading comment - upgrade per-entry empty-field checks to require to avoid empty-string pollution of the duplicate-detection maps - assert no path appears in both ignore maps (cross-pollination) - assert every mapping/ignore entry is still a live leaf on its type so renames and deletions surface instead of leaving stale entries - rewrite caCertPath, sensitiveHeaders, and serviceName justifications to name the actual wiring symbols a reviewer can grep for Tighten the FlattenJSONLeafFields godoc to describe the one-level self-reference expansion that maxStructRevisits actually permits. Co-Authored-By: Claude Opus 4.7 (1M context) * Trim drift walker and its tests Simplify cycle detection: stop on first revisit instead of allowing one self-referential expansion. The "expand once" gold-plating produced a "next." entry on linked-list-shaped types, but no real CRD or runtime config has cyclic shape, and stop-on-revisit is the simpler contract for drift detection. The visited tracker becomes a map[reflect.Type]struct{} and maxStructRevisits goes away. Compress the FlattenJSONLeafFields godoc from a 9-bullet semantics list into one paragraph. Most of the bullets are now subsumed by the single "json.Marshaler => leaf, otherwise recurse on Struct/Slice/Array/Map" rule. The detailed encoding/json reference belongs in the standard library, not here. Drop redundant subtests in TestFlattenJSONLeafFields. After the json.Marshaler refactor, the json.RawMessage / thvjson.Map+Any / vmcpconfig.Duration cases all exercise the same short-circuit branch as metav1.Duration, so one Marshaler example is enough. Drop slice-of- pointer-to-struct (covered by combining the pointer-deref and slice-of- struct cases). Fold the dedicated PointerInputDereferenced test into the table. Remove TestFlattenJSONLeafFields_OutputIsSorted: the table- driven test already pins exact sorted-string equality on every case. Update the recursive-type expectation to ["name"] to lock in the new stop-on-revisit semantics. Co-Authored-By: Claude Opus 4.7 (1M context) * Use //nolint:exhaustive for the kind switch golangci-lint v2 doesn't honor the //exhaustive:ignore source directive in this configuration; the project-wide nolint convention works. The switch genuinely falls through to a default leaf branch for every Kind not listed (primitives, interfaces, channels, etc.) — the suppression is a confirmed false positive. Co-Authored-By: Claude Opus 4.7 (1M context) * Address review feedback on drift detection framework Three changes from PR review: 1. Fix bogus symbol name in caCertPath justification (telemetry_drift_test.go). The string referenced runconfig.AppendTelemetryRunnerOption, which does not exist anywhere in the tree. The actual wiring lives at cmd/thv-operator/pkg/runconfig/telemetry.go:33 inside AddMCPTelemetryConfigRefOptions, where config.CACertPath is assigned from the operator-computed volume-mount path. 2. Drop the standalone "if inline { return \"\" }" branch in the path- segment builder (reflect.go). encoding/json does not recognize the ",inline" tag option — only ",omitempty" and ",string" are parsed; any other token is silently discarded. Flattening is driven entirely by StructField.Anonymous combined with the absence of an explicit JSON name. Today every ",inline" usage in the codebase happens to also be on an anonymous field, so the bug was masked, but a future named field tagged json:"foo,inline" would have been incorrectly flattened by the walker while encoding/json would emit "foo":{...}. Add a regression test (named_field_with_,inline_tag_stays_nested) to pin the corrected behavior, and simplify parseJSONTag to match. 3. Extract a generic AssertNoDrift[Runtime, CRD] helper (internal/testutil/drift.go). The previous three top-level test functions (CRDFieldsCovered, RuntimeFieldsCovered, MappingTableSanity) are now subtests run inside the helper, so a new domain (OIDC, vMCP, etc.) drops to a single TestXxxDrift function that supplies its three tables. The helper carries Domain through into failure messages so output stays as actionable as before. The FieldMapping type and liveLeafSet helper move to the testutil package to live alongside the harness. Net: ~130 LoC removed from telemetry_drift_test.go, ~220 LoC of reusable harness added in drift.go. Co-Authored-By: Claude Opus 4.7 (1M context) * Fix lint failures on drift detection framework CI flagged two issues on the previous push: 1. cyclomatic complexity 19 of `assertTableSanity` (limit 15). Extract the five independent invariants — empty/duplicate mappings, mapped- and-ignored overlap, justification non-emptiness, cross-pollination, and stale-entry detection — into named helpers. The orchestrator becomes a six-line dispatch and each helper is small enough to read in one screen. The stale-entry helper is parameterized by side so the CRD and runtime passes share one body. 2. paralleltest on TestTelemetryConfigDrift. Add t.Parallel() to the outer test; subtests inside AssertNoDrift already call it. Also unrelated to this PR: TestGetOverlayMounts in pkg/ignore is a known intermittent flake (race), not introduced by these changes.

HeaderForwardConfig and the Backend / BackendTarget fields carry per-backend header forwarding state through the vMCP domain types. * Adopt wirefmt in MCPRemoteProxy controller Replace the local SecretEnvVarName helpers with the shared wirefmt encoder so the operator and vMCP runtime stay in lockstep on env-var naming. * Refactor externalauth helpers in operator controllerutil Surfaced while wiring headerForward through the MCPRemoteProxy and MCPServerEntry controllers. Tightens the helper contracts so callers in the new code paths share the same lookup signature. * Validate headerForward Secret refs on MCPServerEntry The headerForward field already exists on the MCPServerEntry CRD; this commit adds the reconciler validation that walks spec.headerForward.addHeadersFromSecret, confirms each referenced Secret exists in the namespace, and surfaces the result as a HeaderSecretRefsValidated status condition. Mirrors the validation MCPRemoteProxy already performs for its header Secret refs. * Emit headerForward env vars from VirtualMCPServer deployment The VirtualMCPServer reconciler now renders the entry-side headerForward manifest into the vMCP pod env via the wirefmt encoding. Plaintext values land directly; Secret-backed values become valueFrom.secretKeyRef so the runtime never sees raw secret material in CRD or pod spec. * Apply headerForward in vMCP client The HTTP client decorator injects per-backend headers (plaintext and Secret-resolved) on every outbound request: list, call, and health checks. Secret identifiers are resolved through the standard EnvironmentProvider, so the client never holds raw secret values. * Thread per-backend headerForward through aggregator, workloads, and CLI The static-mode discoverer now keys headerForward by normalized backend name and stamps each Backend with its config at discovery time. The Kubernetes workload discoverer surfaces the same field on managed entries, and the health monitor forwards it through to client calls. vMCP startup ingests the operator-emitted TOOLHIVE_HEADER_FORWARD_* env vars and routes the resulting per-backend map through serve into the discoverer. --- .../api/v1beta1/mcpserverentry_types.go | 13 + .../controllers/mcpremoteproxy_deployment.go | 3 +- .../controllers/mcpremoteproxy_runconfig.go | 3 +- .../controllers/mcpserverentry_controller.go | 161 ++++++++++ .../mcpserverentry_controller_test.go | 150 +++++++++ .../virtualmcpserver_deployment.go | 159 ++++++++++ .../virtualmcpserver_deployment_test.go | 299 ++++++++++++++++++ .../pkg/controllerutil/externalauth.go | 31 +- .../pkg/controllerutil/externalauth_test.go | 68 +--- pkg/vmcp/aggregator/discoverer.go | 28 +- pkg/vmcp/aggregator/discoverer_test.go | 4 + pkg/vmcp/cli/header_forward_env.go | 74 +++++ pkg/vmcp/cli/header_forward_env_test.go | 151 +++++++++ pkg/vmcp/cli/serve.go | 11 + pkg/vmcp/client/client.go | 17 +- pkg/vmcp/client/header_forward.go | 160 ++++++++++ .../client/header_forward_integration_test.go | 134 ++++++++ pkg/vmcp/client/header_forward_test.go | 243 ++++++++++++++ pkg/vmcp/headerforward/wirefmt/wirefmt.go | 92 ++++++ .../headerforward/wirefmt/wirefmt_test.go | 132 ++++++++ pkg/vmcp/health/monitor.go | 8 +- pkg/vmcp/registry.go | 1 + pkg/vmcp/types.go | 31 ++ pkg/vmcp/workloads/k8s.go | 38 +++ pkg/vmcp/workloads/k8s_test.go | 173 ++++++++++ 25 files changed, 2082 insertions(+), 102 deletions(-) create mode 100644 pkg/vmcp/cli/header_forward_env.go create mode 100644 pkg/vmcp/cli/header_forward_env_test.go create mode 100644 pkg/vmcp/client/header_forward.go create mode 100644 pkg/vmcp/client/header_forward_integration_test.go create mode 100644 pkg/vmcp/client/header_forward_test.go create mode 100644 pkg/vmcp/headerforward/wirefmt/wirefmt.go create mode 100644 pkg/vmcp/headerforward/wirefmt/wirefmt_test.go diff --git a/cmd/thv-operator/api/v1beta1/mcpserverentry_types.go b/cmd/thv-operator/api/v1beta1/mcpserverentry_types.go index 6c5043d6e7..04c989230b 100644 --- a/cmd/thv-operator/api/v1beta1/mcpserverentry_types.go +++ b/cmd/thv-operator/api/v1beta1/mcpserverentry_types.go @@ -101,6 +101,11 @@ const ( // ConditionTypeMCPServerEntryRemoteURLValidated indicates whether the RemoteURL passes // format and SSRF safety checks.

This unblocks third-party MCP servers (e.g. Atlassian Rovo) whose initialize response contradicts their implemented method set, so users still get the backend's tools instead of silently losing them. Implements changes for issue #5231: - Recover from errors.Is(err, mcp.ErrMethodNotFound) on resources/list and prompts/list with a WARN log naming the backend and method. - Keep tools/list failures and non-(-32601) errors from list methods fatal so we are not silencing arbitrary failures. - Add table-driven unit tests with a fake JSON-RPC backend covering the recoverable, fatal, and regression-guard cases. * Address PR #5232 review feedback Addresses stacklok/toolhive#5232 review comments: - MEDIUM mcp_session_capabilities_test.go (3211850392): add success-path rows for resources and prompts so the switch's default arm (the populate loop) is exercised, including BackendID field-mapping assertions. - LOW mcp_session.go (3211850393): tighten the recovery comment in both the resources and prompts switch arms to a single rationale-focused sentence. - LOW mcp_session_capabilities_test.go (3211850399): replace wantToolsCalled bool with wantToolsCalls int so the assertion shape matches the resources/prompts counters and zero-call cases become expressible. - LOW mcp_session_capabilities_test.go (3211850401): use assert.ErrorContains in place of assert.True(strings.Contains(...)) and drop the now-unused strings import. - LOW mcp_session.go (3211850404): enrich the WARN log in both arms with workload name and base URL so the breadcrumb is grep-friendly without an ID-to-name lookup. - LOW mcp_session.go (3211850406): note in the recovery comment that HTTP-level method absence is intentionally fatal, scoping the tolerance to JSON-RPC -32601. --- .../session/internal/backend/mcp_session.go | 77 ++- .../backend/mcp_session_capabilities_test.go | 444 ++++++++++++++++++ 2 files changed, 496 insertions(+), 25 deletions(-) create mode 100644 pkg/vmcp/session/internal/backend/mcp_session_capabilities_test.go diff --git a/pkg/vmcp/session/internal/backend/mcp_session.go b/pkg/vmcp/session/internal/backend/mcp_session.go index 75425e98f6..4ad386ae39 100644 --- a/pkg/vmcp/session/internal/backend/mcp_session.go +++ b/pkg/vmcp/session/internal/backend/mcp_session.go @@ -5,6 +5,7 @@ package backend import ( "context" + "errors" "fmt" "io" "log/slog" @@ -385,40 +386,66 @@ func initAndQueryCapabilities( if serverCaps.Resources != nil { resResult, listErr := c.ListResources(ctx, mcp.ListResourcesRequest{}) - if listErr != nil { + switch { + case errors.Is(listErr, mcp.ErrMethodNotFound): + // Tolerate JSON-RPC -32601 here so a backend that advertises the + // resources capability but does not implement resources/list (e.g. + // Atlassian Rovo, see #5231) still contributes its tools instead of + // being dropped.

These fail on main: wrapBackendError does not recognize the new transport.ErrAuthorizationRequired or ErrOAuthAuthorizationRequired sentinels, so the error falls through to ErrBackendUnavailable and the health monitor categorizes the probe as BackendUnhealthy. Cases added: - TestWrapBackendError: ErrAuthorizationRequired, the wrapped production chain (transport.Error + AuthorizationRequiredError), and ErrOAuthAuthorizationRequired must each map to ErrAuthenticationFailed. - TestHealthChecker_CheckHealth_AuthErrorsCategorizesAsUnauthenticated: the raw mcp-go chain reaching the checker must classify as BackendUnauthenticated when no outgoing auth strategy is configured. - TestHealthChecker_CheckHealth_AuthErrorWithOutgoingAuthIsHealthy: upstream_inject + the raw mcp-go chain (North's exact reproducer) must classify as BackendHealthy with nil error so the monitor records a successful check and the WARN spam stops. * Recognize mcp-go authorization-required sentinels as auth errors mcp-go v0.49.0 introduced transport.ErrAuthorizationRequired (and the companion transport.ErrOAuthAuthorizationRequired from the OAuth-handler path) as sentinels for 401 responses. wrapBackendError did not check for either, so the error fell through to ErrBackendUnavailable and the vMCP health monitor categorized auth-protected backends (e.g. GitHub Copilot behind upstreamInject) as BackendUnhealthy on every 30s probe, producing WARN log spam and an ever-climbing consecutive_failures counter. Two-part fix: 1. wrapBackendError now matches both new sentinels via errors.Is and wraps them as ErrAuthenticationFailed. This is the principled fix for the production code path through BackendClient. 2. IsAuthenticationError now matches the substring "authorization required" as a fallback for paths where the typed sentinel is not preserved through the error chain (e.g. tests using a mock BackendClient, or future error-chain breakage in mcp-go's Unwrap). With both in place, the existing auth-aware classification logic (#4935) engages: backends with an outgoing auth strategy configured report BackendHealthy on auth challenge (the expected response to a no-credential probe), and misconfigured backends correctly surface BackendUnauthenticated. Closes #5223 * Address review feedback on test coverage breadth R3 + R4 (test matrix gap on outgoing-auth strategies): TestHealthChecker_CheckHealth_AuthErrorWithOutgoingAuthIsHealthy previously covered the new mcp-go authorization-required chain only against upstream_inject. Add token_exchange and header_injection rows so the matrix pins all three strategies that route through the same authErrorStatus branch. R5 (negative test for substring over-classification): TestIsAuthenticationError gains a row for a benign validation message containing the words 'authorization' and 'required' separated by punctuation ("field 'authorization' required"). This pins that the current matcher's contiguous "authorization required" substring does not over-classify, so a future loosening of the matcher (e.g. whitespace-tolerant) would not silently regress. R7 (test names should describe assertions, not tickets): Renamed the issue-numbered cases to describe the chain shape ("transport.Error wrapping AuthorizationRequiredError"). The issue reference remains in the case comment. Note on R4 (StrategyTypeUnauthenticated against the new chain): TestCategorizeError already pins the misconfig branch at the unit level for sentinel-shaped errors.

Route exchangeToken through oauthproto.NewFormRequest + oauthproto.DoTokenRequest and drop the in-package helpers plus the now-unused imports (encoding/json, io, log/slog, strconv, time). exchange.go changes: - Delete createTokenExchangeRequest, executeTokenExchangeRequest, parseTokenExchangeResponse, validateResponseStatus, the local response struct, and the local maxResponseBodySize constant. exchangeToken collapses to three calls: buildFormData, oauthproto.NewFormRequest, oauthproto.DoTokenRequest. - Preserve RFC 8693 Section 2.2.1 at the call site. oauthproto.ParseTokenResponse is deliberately permissive about token_type (x/oauth2 library parity, Google historically omits it), so tokenSource.Token() still enforces both token_type and issued_token_type for RFC 8693 compliance. The redundant AccessToken-empty check is gone; oauthproto.ParseTokenResponse emits "oauth: token response missing access_token (RFC 6749 Section 5.1)" centrally. - Rename buildTokenExchangeFormData to buildFormData now that the package context makes the TokenExchange prefix redundant. - The SubjectTokenType mutation (c.SubjectTokenType = normalized) is preserved — pkg/vmcp and pkg/runner read the field post-Validate — and pinned by a new TestExchangeConfig_Validate_NormalizesSubjectTokenType regression test covering short forms, already-normalized URNs, and empty. Test changes: - Replace the in-file testResponse struct and responseBuilder helper with oauthtest.ResponseBuilder from pkg/oauthproto/oauthtest. The shared builder was introduced in the first commit of this series specifically so tokenexchange and the upcoming jwtbearer grant stop drifting; keeping a local duplicate defeated the point. Same treatment for three literal testResponse{...} constructions in middleware_test.go. - Update error-substring assertions to match the new emitters in pkg/oauthproto: "token exchange request failed" -> "oauth: token request failed", "failed to parse token exchange response" -> "oauth: cannot parse token response", "failed to create token exchange request" -> "tokenexchange: build request". In pkg/vmcp/auth/strategies/tokenexchange_test.go, "empty access_token" -> "missing access_token" because oauthproto.ParseTokenResponse now owns that §5.1 check. RetrieveError.Body preservation: - pkg/oauthproto.parseRetrieveError leaves the raw upstream body on *oauth2.RetrieveError so general-purpose callers can surface server replies verbatim. tokenexchange historically scrubbed this field to prevent raw IdP content from leaking into error strings (matching the pattern used by Ory Hydra). exchangeToken now opts back into the stricter behavior with an errors.As + Body = nil step right after DoTokenRequest. The TestExchangeToken_HTTPErrorResponses table re-asserts Body == nil so the property cannot drift again. User-facing: operators or alerts keyed on the old tokenexchange error strings will need to pick up the new substrings. Error types are unchanged (*oauth2.RetrieveError still surfaces on non-2xx and 2xx-with-error bodies; errors.As chains still work) --- pkg/auth/tokenexchange/exchange.go | 208 +++------------ pkg/auth/tokenexchange/exchange_test.go | 242 ++++++++---------- pkg/auth/tokenexchange/middleware_test.go | 35 ++- .../auth/strategies/tokenexchange_test.go | 6 +- 4 files changed, 154 insertions(+), 337 deletions(-) diff --git a/pkg/auth/tokenexchange/exchange.go b/pkg/auth/tokenexchange/exchange.go index 75c422863b..b06088ed7c 100644 --- a/pkg/auth/tokenexchange/exchange.go +++ b/pkg/auth/tokenexchange/exchange.go @@ -6,29 +6,17 @@ package tokenexchange import ( "context" - "encoding/json" + "errors" "fmt" - "io" - "log/slog" "net/http" "net/url" - "strconv" "strings" - "time" "golang.org/x/oauth2" "github.com/stacklok/toolhive/pkg/oauthproto" ) -// maxResponseBodySize bounds io.LimitReader in executeTokenExchangeRequest so -// a pathological server cannot exhaust memory.

23:05:46 +0100 Subject: [PATCH 137/291] Move tokenexchange under pkg/oauthproto (#5251) Relocate pkg/auth/tokenexchange to pkg/oauthproto/tokenexchange so the RFC 8693 Token Exchange grant sits next to the shared grant-helper primitives (pkg/oauthproto/grants.go, pkg/oauthproto/oauthtest) and the upcoming RFC 7523 JWT Bearer grant. With the refactor complete, pkg/oauthproto is the single home for OAuth 2.0 grant machinery in this repo; having one grant under pkg/auth and another under pkg/oauthproto would have been confusing. Pure rename. All source files move intact; every import path updated from github.com/stacklok/toolhive/pkg/auth/tokenexchange to github.com/stacklok/toolhive/pkg/oauthproto/tokenexchange. Also updated stale doc and agent references to the old path in docs/middleware.md, docs/operator/crd-api.md, and .claude/agents/oauth-expert.md. Regenerated docs/server/ swagger so the schema component key reflects the new import path. The wire format of tokenexchange.Config is unchanged; only the OpenAPI $ref key (a swaggo artifact derived from the Go import path) differs. task test and task lint-fix are clean. --- .claude/agents/oauth-expert.md | 2 +- .../v1beta1/mcpexternalauthconfig_types.go | 2 +- .../pkg/controllerutil/tokenexchange.go | 2 +- cmd/thv/app/auth_flags.go | 2 +- cmd/thv/app/proxy.go | 2 +- docs/middleware.md | 2 +- docs/operator/crd-api.md | 2 +- docs/server/docs.go | 86 +++++++++---------- docs/server/swagger.json | 86 +++++++++---------- docs/server/swagger.yaml | 78 ++++++++--------- pkg/oauthproto/grants.go | 2 +- .../tokenexchange/exchange.go | 0 .../tokenexchange/exchange_test.go | 0 .../tokenexchange/middleware.go | 0 .../tokenexchange/middleware_test.go | 0 pkg/runner/config.go | 2 +- pkg/runner/config_builder.go | 2 +- pkg/runner/config_builder_test.go | 2 +- pkg/runner/middleware.go | 2 +- pkg/transport/http.go | 2 +- pkg/transport/http_test.go | 2 +- pkg/vmcp/auth/strategies/tokenexchange.go | 2 +- 22 files changed, 140 insertions(+), 140 deletions(-) rename pkg/{auth => oauthproto}/tokenexchange/exchange.go (100%) rename pkg/{auth => oauthproto}/tokenexchange/exchange_test.go (100%) rename pkg/{auth => oauthproto}/tokenexchange/middleware.go (100%) rename pkg/{auth => oauthproto}/tokenexchange/middleware_test.go (100%) diff --git a/.claude/agents/oauth-expert.md b/.claude/agents/oauth-expert.md index 9d8cc047b0..08bc5e1692 100644 --- a/.claude/agents/oauth-expert.md +++ b/.claude/agents/oauth-expert.md @@ -46,7 +46,7 @@ Before providing guidance on OAuth/OIDC details, use WebFetch to verify RFC or s -

Telemetry only worked when a workload was created from the CLI. Extract the "build *telemetry.Config from OpenTelemetryConfig" logic into a shared helper in pkg/runner so the CLI's run flags and the API's BuildFullRunConfig can no longer diverge. Wire the helper into the API path and refactor the CLI's createTelemetryConfig to delegate to it.

The API responded with a generic HTTP 500 "Failed to get registry provider", and the actionable migration hint was visible only in main.log. Desktop clients had no way to distinguish this case from an internal error. Add a typed *LegacyFormatError (sister of *UnavailableError) carrying the offending source URL. Wire it through the four registry GET handlers and the v0.1 router so the response is now HTTP 503 with a structured "registry_legacy_format" code and the migration hint in the message body. The upstream_parser sentinel errLegacyFormat is now an instance of *LegacyFormatError; its Is() method preserves errors.Is(err, errLegacyFormat) for existing callers while enabling errors.As extraction of the URL. Fixes #5259 Co-Authored-By: Claude Opus 4.7 (1M context) * Switch registry_legacy_format status code to 502 Bad Gateway 503 was inconsistent with the existing PUT registry handler that already returns 502 for the same legacy-format detection via ErrRegistryValidationFailed (pkg/api/v1/registry.go updateRegistry handler). 502 is also the correct RFC 9110 §15.6.3 code: thv serve acts as a gateway to the upstream registry and the upstream returned a response we cannot process. 503 is reserved for "temporary overload or scheduled maintenance" which does not match a misconfigured registry source. Co-Authored-By: Claude Opus 4.7 (1M context) * Fix stale 503 references in doc comments Two doc comments missed the 502 update from the previous commit. The code itself already returns 502 Bad Gateway via writeRegistryLegacyFormatError; only the comments were inconsistent.

RFC 7591 §3.1.1 explicitly permits the AS to override the registered scope, so let operators declare a baseline set that the embedded auth server unions into every DCR registration. This commit only adds the CRD field. The plumbing through RunConfig, the runner, the server provider, and the DCR handler comes in subsequent commits. Refs #5224 * Plumb BaselineClientScopes into auth server RunConfig Add the BaselineClientScopes field on the on-disk RunConfig and copy it from the CRD's EmbeddedAuthServerConfig in the operator-side builder. The runtime Config and the DCR handler are wired in subsequent commits; startup validation that the baseline is a subset of ScopesSupported lands with the next commit. Refs #5224 * Validate baseline scopes are subset of supported If an operator configures baseline_client_scopes with a value missing from scopes_supported, the embedded DCR handler would later register clients with a scope the server does not advertise, and fosite would reject those clients at /oauth/authorize with invalid_scope. Catching the misconfiguration at startup gives operators a clear error instead of debugging silent rejections in production. Add RunConfig.Validate() with a subset check, and call it from the runner entry point before any secret resolution or HTTP wiring. errors.Join wraps the (currently single) sub-check so future RunConfig invariants compose without dropping existing checks. Refs #5224 * Resolve baseline scopes into runtime Config Add BaselineClientScopes to the runtime Config struct and copy it from RunConfig in the runner's resolvedCfg block. The DCR handler needs the baseline at request time, so it must travel through the runtime Config the same way ScopesSupported does. The field is populated but not yet consumed by any downstream code; the next commit plumbs it from Config into the AuthorizationServerConfig that the DCR handler reads. Refs #5224 * Forward baseline scopes to AuthorizationServerConfig Add BaselineClientScopes to AuthorizationServerParams and AuthorizationServerConfig and copy it through Config -> Params -> ASConfig so the DCR handler can read it via h.config in the next commit. Defense-in-depth: validateParams re-checks the baseline-subset-of- supported invariant. RunConfig.Validate already enforces it for the runner-driven path, but a direct caller of authserver.New(Config) bypasses that check. Validating again at NewAuthorizationServerConfig catches the misconfiguration at the deepest layer where both slices are simultaneously available. Refs #5224 * Add UnionScopes helper for DCR baseline injection The DCR registration handler will use this in the next commit to union an operator-configured scope baseline into every newly registered client's scope set. Pulling the union into a separate helper keeps the handler readable and lets the order/dedup contract be unit-tested in isolation. Order matters: requested scopes appear first (in input order), then baseline scopes not already present. The handler uses slices.Equal(union, requested) to decide whether to log a WARN, so stable order is part of the contract. Refs #5224 * Apply baseline scope union to DCR registration This is the user-visible behavior change: between scope validation and client construction, the DCR handler now unions the operator-configured BaselineClientScopes into the registered client's scope set. RFC 7591 §3.2.1 permits the AS to replace requested client metadata, which is what fixes the Claude Code bug (anthropics/claude-code#4540): a client whose DCR request narrows the scope field can still request the baseline at /oauth/authorize without invalid_scope rejection. WARN logs only when the union actually expands the requested set (slices.Equal short-circuits the no-op path). The DCR response at the bottom of the handler already echoes the effective scope set back to the client, so clients see exactly what they got. Refs #5224 * Test DCR handler baseline scope behavior Cover the four contract paths in TestRegisterClientHandler_- BaselineClientScopes: empty client scope unions with baseline, baseline-as-subset of requested produces no expansion, partial overlap appends only non-overlapping scopes, disjoint baseline expands the registered set, and nil baseline preserves existing behavior. DoAndReturn captures the fosite client passed to RegisterClient so the test asserts not only that the DCR response echoes the expected scope set but also that the same set actually reaches storage. The disjoint case is the canonical regression test for anthropics/claude-code#4540. Refs #5224 * Test RunConfig.Validate baseline subset check TestRunConfigValidate covers seven contract paths: nil and empty baselines pass with non-empty scopes_supported, single and multi-element baseline subsets pass, a baseline scope missing from scopes_supported is reported with both the offending scope name and the "not in scopes_supported" phrase, a non-nil baseline with nil scopes_supported fails closed, and the helper reports a missing scope when multiple are missing. Refs #5224 * Add end-to-end DCR scope-narrowing regression test This is the canonical regression test for anthropics/claude-code#4540 (Claude Code DCR-registers with a narrowed scope but later requests the full set at /oauth/authorize). Three sequential subtests on a shared client_id: 1. DCR-register with scope="openid" against a server configured with BaselineClientScopes=["offline_access"]; assert the response's scope field echoes "openid offline_access". 2. /authorize with scope="openid offline_access" against the same client; assert HTTP 302 redirect to upstream (not 400 invalid_scope, the pre-fix behavior). 3. /authorize with a scope outside scopes_supported; assert fosite rejects with invalid_scope. Guards against silent privilege escalation if BaselineClientScopes ever drifts to bypass the ScopesSupported boundary. WithBaselineClientScopes is added to the test helpers alongside the existing WithScopesSupported option. Refs #5224 * Regenerate swagger docs for BaselineClientScopes The new BaselineClientScopes field on authserver.RunConfig is referenced (transitively) by the API's swagger surface, so the CI docs check requires the regenerated swagger.json/yaml/docs.go. Mechanical regen via task docs; no behavioral or hand-written change. Refs #5224 * Document baseline scope privilege risk; log at startup Trey's review (F1) noted the trust boundary is only weakly defended in docs. Two changes address this: The CRD field doc gains an explicit privilege-escalation example so operators writing YAML see the warning, not just someone reading the handler source. A baseline of "admin:read" is now called out by name as something they should never configure. NewAuthorizationServerConfig emits a one-time INFO log when the baseline is non-empty, so operators can verify in their logs what their DCR registrations will be auto-granted. This matches the "INFO sparingly — only for long-running operations" rule for a process-lifetime event. Refs #5224 * Demote baseline-scope expansion log to Debug Per .claude/rules/go-style.md, Warn is for non-fatal issues (deprecations, fallback, cleanup failures), and Info is for long-running events. Baseline-driven expansion of a DCR scope set is the intended behavior whenever baseline_client_scopes is configured, not a problem to flag — so per-registration audit belongs at Debug. Operator-visible signal that the baseline is in effect already comes from the one-time Info log at NewAuthorizationServerConfig startup. Refs #5224 * Clone caller-supplied scope and audience slices The DCR handler reads BaselineClientScopes, ScopesSupported, and AllowedAudiences via h.config on every request. They all flow by reference from cfg through RunConfig → Config → AuthorizationServerParams → AuthorizationServerConfig. Nothing mutates them today, but the runner is the natural boundary at which operator-supplied input becomes runtime state, and slices.Clone costs nothing for the bounded slice sizes involved. Cloning once here lets every downstream stage share by reference safely against a future hot-reload path or test code that retains the original. Refs #5224 * Test direct-caller baseline subset gate NewAuthorizationServerConfig has its own subset check (validateParams → ValidateScopeSubset) so a direct caller that bypasses RunConfig.Validate is still rejected when BaselineClientScopes contains a scope absent from ScopesSupported. The case lived in design only — adding it to the existing TestNewAuthorizationServerConfig_InvalidConfig table protects the gate against silent regression in a future refactor. Refs #5224 * Assert invalid_scope in the 400 branch of negative test Symmetric to the redirect-with-error branch, which already asserts on \`invalid_scope\` in the query string: if fosite ever returns 400 directly (rather than redirecting with error), the test must still assert the error code is invalid_scope and not something else (server_error, unauthorized_client, etc.). Otherwise a future fosite upgrade could swap in a different code and the privilege-escalation regression would silently slip past this test. Reads the body up front so the existing structure works without teeing around a deferred drain. Refs #5224 * Reject empty and malformed baseline scope entries at admission A baselineClientScopes value of [""] or ["foo bar"] would slip past admission and only fail at the runtime subset check inside NewEmbeddedAuthServer — confusing error, late feedback. Two kubebuilder item-level validations move the rejection forward to the apiserver: - items:MinLength=1 — no empty strings - items:Pattern=^[\x21\x23-\x5B\x5D-\x7E]+$ — the RFC 6749 §3.3 scope-token charset (printable ASCII excluding space, ", and \) Operators now get a clean "spec is invalid" from the apiserver instead of a CrashLoopBackOff with a subset-check log line. Refs #5224 * Drop call-site list from ValidateScopeSubset doc The previous doc enumerated two call sites and missed a third (Config.applyDefaults's empty-supported-with-non-empty-baseline check, which is a related invariant even though it doesn't go through this helper). Per .claude/rules/go-style.md "Keep Comments Synchronized With Code", call-site lists rot when call sites move or new ones appear. Describing what the function does and why callers share it is enough for the reader. Refs #5224 * Clarify scope-response comment in DCR handler The previous wording "validated against ScopesSupported and, if configured, unioned with BaselineClientScopes" could be read as "the unioned set is validated against ScopesSupported." It isn't — ValidateScopes runs against the client-supplied set BEFORE the union, and the union is trusted by construction because BaselineClientScopes is itself a subset of ScopesSupported per startup-time validation. Rephrased to make the ordering and the "not re-validated here" intent explicit. Refs #5224 * Add baseline subset check to Config.Validate A caller that constructs the runtime Config directly (bypassing YAML loading and therefore bypassing RunConfig.Validate) was only caught by the inner validateParams in the provider layer. That works but gives a deeper call stack at the failure site. Adding the check to Config.Validate closes the gap and makes the three-gate defense in depth (RunConfig.Validate → Config.Validate → validateParams) fully symmetric on the subset invariant. New TestConfigValidate case asserts the wired-up check fires with the same error message that the other gates produce. Refs #5224 * Honor scopesSupported defaults in baseline subset check The natural first-use config baselineClientScopes: - offline_access was failing at startup because RunConfig.Validate (and Config.Validate after F12) checked baselineClientScopes against the raw scopesSupported slice, which the operator passes as nil to mean "use server defaults" (documented at controllerutil/authserver.go:461 and vmcpconfig/converter.go:404-415 deriveScopesSupported). applyDefaults only substitutes registration.DefaultScopes later, after validation has already rejected the config. Both validation gates now treat empty scopesSupported as equivalent to registration.DefaultScopes for the subset check — without mutating the struct, so wire-format stays faithful to operator input. The applyDefaults inner guard that rejected this case is now dead and removed; defaulting symmetry with HMACSecrets and KeyProvider is restored. Doc comments on both RunConfig.BaselineClientScopes and Config.BaselineClientScopes describe the new contract. Tests flip the previously-rejecting fixtures to the documented happy path and add coverage for the still-rejecting case (nil supported with a baseline scope outside DefaultScopes). Refs #5224 * Regenerate swagger docs after baseline-validation fix The previous commit reworded RunConfig.BaselineClientScopes' Go doc comment to describe the new "nil scopesSupported uses DefaultScopes for the subset check" contract. swag init renders that doc comment into docs/server/swagger.{json,yaml,docs.go}, so the verify-swagger CI check fails until the artifacts are regenerated to match. Mechanical regen via swag init; no behavioral or hand-written change.

Each new error code that needs structured handling had to be wired into five places, and the existing v0.1 router did the same `errors.Is` check inline instead of going through `isRegistryAuthError`. Extract a single `writeProviderError(w, err) bool` helper that handles all three known failure modes and returns whether a response was written. Each callsite collapses to two lines and a generic fallback. Drop the now-unused `errors` and `registry/auth` imports from `registry_v01.go`. Also lower the legacy-format log to `slog.Warn`: it signals a user misconfiguration that the API has already translated into a 502 with an actionable hint, not a server-side failure that on-call should investigate. The upstream-unavailable path stays at `slog.Error` since it usually does indicate a real outage.

There was no clean way for a user or downstream distribution to disable update checks in a non-CI runtime such as the operator. Add TOOLHIVE_SKIP_UPDATE_CHECK as an explicit opt-out env var. When set to "true" (case-insensitive), ShouldSkipUpdateChecks() returns true, which skips update checks from the CLI, the API server middleware, and the operator telemetry service. Update-derived usage metrics are also skipped, since usagemetrics.shouldEnableMetrics gates on the same function -- this is the intended coupling. * Address review: test, regroup const, document in operator chart - Add TestShouldSkipUpdateChecks_SkipEnvVar covering true / TRUE / unset / false / unrecognized values. Clears CI env vars via t.Setenv so the opt-out path is exercised regardless of how the test binary is run. - Move EnvVarSkipUpdateCheck next to ciEnvVars so all "things that decide skip" live together. Expand the doc comment to spell out the usage-metrics coupling. - Document the env var on the operator chart's `operator.env` field so it is discoverable from values.yaml and the auto-generated chart README.

The grant exchanges a signed JWT assertion for an OAuth 2.0 access token at a target authorization server's token endpoint. TokenURL validation reuses pkg/networking.ValidateEndpointURL plus host, fragment, and userinfo checks to enforce RFC 6749 Section 3.2 (token endpoints must use TLS) and to reject URLs that smuggle credentials in the URL itself. The token_type field in the success response is validated as required by RFC 6749 Section 5.1. HTTP error responses are returned as *oauth2.RetrieveError (from golang.org/x/oauth2) with the raw Body scrubbed before return, matching pkg/oauthproto/tokenexchange's stricter behavior so error strings cannot leak upstream content into logs. Client authentication is HTTP Basic per RFC 6749 Section 2.3.1; the package targets confidential clients per XAA / ID-JAG §8.1 and does not support public-client identification via a body client_id parameter. Also add the GrantTypeJWTBearer URN constant to pkg/oauthproto, the first consumer of which is this package. The jwtbearer package is the Step B primitive used by the XAA (ID-JAG) strategy. It has no XAA-specific behaviour at this layer and works for any RFC 7523 JWT-Bearer exchange with a confidential client. --- pkg/oauthproto/constants.go | 3 + pkg/oauthproto/jwtbearer/doc.go | 7 + pkg/oauthproto/jwtbearer/grant.go | 168 ++++++++++++ pkg/oauthproto/jwtbearer/grant_test.go | 341 +++++++++++++++++++++++++ 4 files changed, 519 insertions(+) create mode 100644 pkg/oauthproto/jwtbearer/doc.go create mode 100644 pkg/oauthproto/jwtbearer/grant.go create mode 100644 pkg/oauthproto/jwtbearer/grant_test.go diff --git a/pkg/oauthproto/constants.go b/pkg/oauthproto/constants.go index 1312ddb2b1..fce50b6cbd 100644 --- a/pkg/oauthproto/constants.go +++ b/pkg/oauthproto/constants.go @@ -69,6 +69,9 @@ const ( const ( // GrantTypeTokenExchange is the OAuth 2.0 Token Exchange grant type (RFC 8693).

Extract DCR resolver into pkg/auth/dcr (#5198) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Extract DCR resolver into pkg/auth/dcr Sub-issue 4a of #5145. Creates the shared pkg/auth/dcr package and migrates the embedded authserver to consume it. The CLI flow migration (pkg/auth/discovery::PerformOAuthFlow) is left to sub-issue 4b (#5219) so this slice stays under the project's PR-size limit. Files moved (renamed via git mv so the diff shows as renames, not deletions + additions): pkg/authserver/runner/dcr.go -> pkg/auth/dcr/resolver.go pkg/authserver/runner/dcr_store.go -> pkg/auth/dcr/store.go pkg/authserver/runner/dcr_test.go -> pkg/auth/dcr/resolver_test.go pkg/authserver/runner/dcr_store_test.go -> pkg/auth/dcr/store_test.go pkg/authserver/runner/dcr_testhelpers_test.go -> pkg/auth/dcr/testhelpers_test.go Public API surface (renamed from runner-package internals because they now cross a package boundary): Resolution (was DCRResolution) Key (was DCRKey, alias to storage.DCRKey unchanged) CredentialStore (was the package-private dcrResolutionCache) ResolveCredentials (was resolveDCRCredentials) NeedsDCR (was needsDCR) ConsumeResolution (was consumeResolution) ApplyResolutionToOAuth2Config (was applyResolutionToOAuth2Config) LogStepError (was logDCRStepError) NewInMemoryStore (new convenience constructor wrapping storage.NewMemoryStorage; mirrors the pattern the per-test newMemoryDCRStore helpers use) NewStorageBackedStore (was the package-private newStorageBackedStore) SanitizeErrorForLog (was sanitizeErrorForLog; promoted to exported because the deferred-cleanup log path in pkg/authserver/runner needs it) Names follow the pkg/auth/dcr.* form so the linter's stuttering check (revive: dcr.DCRResolution would stutter) passes and the surface reads as ordinary package API. resolveSecret was duplicated into the dcr package because pkg/auth/dcr must stay profile-agnostic and cannot reach back into pkg/authserver/runner. The duplication is intentional and called out in a comment; future consolidation can move it into a shared helper if a third caller appears. A parallel TestResolveSecret / TestResolveSecretWithEnvVar suite in pkg/auth/dcr/secret_test.go mirrors the runner-package twin's observable contract so any future drift between the two copies fails CI on at least one side. Review-feedback bits applied alongside the move: - Package doc comment in pkg/auth/dcr/resolver.go now documents the process-global singleflight in a Concurrency section, and labels the profile-agnostic framing as a target state for sub-issue 4b rather than as a description of the current API shape (the package's public API still takes embedded-authserver types). - dcrFlight var doc gains a cross-consumer caveat naming the "third consumer with colliding redirect URI" failure mode. - Flight-key construction extracted into flightKeyOf(Key) string so the canonical key shape is inspectable rather than buried in a string-concatenation literal. - endpointsFromMetadata gains a defensive nil check; the function's doc comment names the oauthproto contract being defended. - newMemoryDCRStore test helper is duplicated across the two packages because Go test helpers cannot be shared without exporting them; the duplication is documented at both sites. Acceptance criteria status (#5145): AC#1 (pkg/auth/dcr exists, exports a stateful resolver, consumed by both call sites): partially met — package exists and is consumed by EmbeddedAuthServer. CLI flow migration is sub-issue 4b (#5219). AC#2 (stateless RFC 7591 helpers in pkg/oauthproto): met (already satisfied before this PR). AC#3 (no direct oauthproto.RegisterClientDynamically calls outside pkg/auth/dcr): not yet met — pkg/auth/discovery still calls it. Resolved by sub-issue 4b (#5219). AC#4 (review-property behaviours apply to CLI flow): not yet met — same dependency on 4b (#5219). Closes #5220. Verified via task lint-fix (0 issues), task license-check (clean), and go test -count=1 -race ./pkg/auth/dcr/... ./pkg/authserver/... (all pass). * Harden pkg/auth/dcr/store.go constructors Addresses stacklok/toolhive#5198 review comments: - MEDIUM pkg/auth/dcr/store.go (3219717154): remove NewInMemoryStore — its CredentialStore return type has no Close method, so the storage.NewMemoryStorage cleanup goroutine the constructor spawns cannot be stopped through the returned interface. With no production caller in this PR (the test helpers wire their own *MemoryStorage with t.Cleanup), removing it is the lightest fix and resolves the "public API ahead of caller" smell. A real consumer with lifecycle management can reintroduce the appropriate shape (e.g. returning a paired shutdown func, or adding Close to CredentialStore) when 4b lands. - MEDIUM pkg/auth/dcr/store.go (3219717166): panic on nil backend in NewStorageBackedStore. Per .claude/rules/go-style.md "Constructor Validation: Fail Loudly on Invalid Input" — a nil backend is unambiguously a programming error and silent acceptance would only delay the nil-pointer dereference to the first Get/Put call, far from the constructor site. * Sweep stale doc references and tighten advisory comments Addresses stacklok/toolhive#5198 review comments: - MEDIUM pkg/authserver/storage/types.go (review body finding #2): DCRCredentials "Converter contract" doc named the now-deleted pkg/authserver/runner/dcr_store.go path and the *DCRResolution type. Updated to pkg/auth/dcr/store.go, *dcr.Resolution, and pkg/auth/dcr/store_test.go (the rename sweep had missed this out-of-diff file). - MEDIUM pkg/auth/dcr/resolver.go (3219717202): dcrFlight doc named EmbeddedAuthServer.dcrStore, a field #5196 removed. Reframed the lifetime contrast in terms of the public injection point — the CredentialStore the embedded authserver constructs and injects into ResolveCredentials — rather than a private field across a package boundary. - MEDIUM pkg/authserver/runner/embeddedauthserver_test.go (3219717294): drift-guard cross-reference was one-way. Added reciprocal doc comments on TestResolveSecret and TestResolveSecretWithEnvVar naming the dcr-side twin at pkg/auth/dcr/secret_test.go, mirroring the dcr-side comment that already names the runner-side twin. - LOW pkg/auth/dcr/resolver.go (3219717277): SanitizeErrorForLog reads as a generic URL sanitiser but only handles http(s); tightened the doc with an "IMPORTANT — caller responsibility" warning that callers receiving non-http(s) URLs with credential-bearing components (redis://user:pass@host, postgres://, etc.) MUST verify those separately. Long-term consolidation into a shared helper appropriate for sub-issue 4b. - LOW pkg/authserver/server/handlers/dcr.go (review body finding #7): log-correlation comment named pkg/authserver/runner/dcr.go; updated to pkg/auth/dcr/resolver.go (also missed by the rename sweep). - LOW pkg/auth/dcr/resolver.go (3219717222): package doc listed *authserver.DCRUpstreamConfig as a parameter type — no exported function takes it; it is reached transitively via OAuth2UpstreamRunConfig.DCRConfig. Applied the reviewer's suggested wording. - LOW pkg/auth/dcr/resolver.go (3219717247): flightKeyOf doc cited RFC 6749 §3.3 (scope tokens) for the ScopesHash field, which is a hex digest, not a scope token. Removed the misaligned citation. - LOW pkg/authserver/runner/embeddedauthserver_test.go (3219717303): qualified four bare "DCRKey" references to "storage.DCRKey" in comments and an assertion message; also fixed a sibling staleness in the same test-doc block where the comment named the deleted dcrStore field. - LOW pkg/auth/dcr/resolver.go (3219717270): added a TODO(#5219) on dcrFlight noting that the flight key must gain a consumer-identifier component when sub-issue 4b wires the CLI flow as the second consumer. The colliding-Key risk is theoretical today; once two profiles share this group it becomes a correctness hazard. Cross-consumer caveat above already describes the failure mode; this TODO ties it to the resolution PR. - LOW pkg/auth/dcr/resolver.go (3219717285): resolveSecret has no production caller in this PR. Tightened the duplication doc to state that the helper is staged for sub-issue 4b (#5219) to wire as part of the CLI flow migration, and that at that point this copy SHOULD be promoted to a shared helper with both consumers migrated in the same PR — i.e., the threshold for consolidation is "second caller wires up", not "third caller appears". * Make DCR consume helpers value-in / value-out Addresses stacklok/toolhive#5198 review comments: - INFO pkg/auth/dcr/resolver.go (3227004701): ConsumeResolution and ApplyResolutionToOAuth2Config mutated caller-supplied pointers and documented the "pass a copy" invariant only in prose. Converted both to value-in / value-out signatures so the no-caller-mutation contract is compile-time enforced rather than a prose discipline the second consumer (CLI flow in sub-issue 4b, #5219) would have to remember. The change is structural but small: two signature changes (ConsumeResolution / ApplyResolutionToOAuth2Config), two function bodies returning the modified value, and call-site updates in embeddedauthserver.go (1 production call site per function) and resolver_test.go (4 test call sites for ConsumeResolution; zero for ApplyResolutionToOAuth2Config). Doc comments updated to describe the new value-in / value-out shape; the "pass a copy of the run-config" prose-discipline paragraph is removed because the type system now enforces it. Pointer-typed fields inside the struct (DCRConfig) still share storage with the caller via the shallow copy, but the only mutation here is nil-assignment to the copy's DCRConfig field, which does not reach back through the caller's pointer; this nuance is now called out in the doc comment. ResolveCredentials is left as *authserver.OAuth2UpstreamRunConfig deliberately: its rc input is read-only (no mutation), so the pointer is just for avoiding a struct copy on the hot path.

Extension point: the existing tokenResponseRewriter (which already reads and parses every successful token-endpoint response to normalise non-standard envelopes) gains a parallel responsibility — extract user identity claims from the same body when the operator configures IdentityFromTokenConfig with gjson dot-notation paths. Identity extraction runs on the RAW pre-rewrite body, so paths are resolved against the original provider response even when TokenResponseMapping is also configured. The rewriter passes the extracted *partialIdentity back to exchangeCodeForTokens via a returned reference; RefreshTokens passes nil and the rewriter is either omitted entirely or runs with identityCfg=nil because providers like Snowflake omit username on refresh and identity is cached at auth-code time in session storage. The new priority chain in BaseOAuth2Provider.ExchangeCodeForIdentity: 1. IdentityFromToken — when configured, return the extracted identity. If extraction failed (path didn't resolve), return ErrIdentityResolutionFailed without consulting userInfo or synthesising — the operator's "identity is in the token" claim is explicit and we surface its failure rather than silently fall through. 2. UserInfo — existing fetchUserInfo path, unchanged. 3. Synthesis — existing synthesizeIdentity path (PR 5094), unchanged. OIDC providers always have ID-token-derived identity, so the OIDC provider's ExchangeCodeForIdentity discards the rewriter's identityFromToken return value with a defensive WARN if a future config-loader bug ever sets IdentityFromToken on an OIDC base config (structurally absent on the OIDC CRD type today). The tripwire test asserts userinfo HTTP is never contacted when identityFromToken is configured, including on extraction failure. Other new tests cover the happy path, userInfo-only regression, the refresh path (no identity extraction), and information disclosure (raw body never appears in error messages or logs above DEBUG). Two existing slog.Info calls in exchangeCodeForTokens are downgraded to slog.Debug to comply with the silent-success-at-INFO rule. Closes: #5156 * Polish IdentityFromToken wiring and tests Post-review polish on top of the IdentityFromToken provider wiring: - Correct the CRD type reference from v1alpha1 to v1beta1 in the doc comments and the architecture doc. The CRD lands on v1beta1. - Suppress the synthesis-mode WARN in NewOAuth2Provider when IdentityFromToken is configured. Previously the warn fired whenever userInfo was nil, including upstreams that resolve identity from the token response. - Downgrade two logs that are too chatty at INFO: - RefreshTokens "refreshing tokens" -> Debug (matches the sibling success log and the silent-success-at-INFO rule). - OIDC defensive ignore-IdentityFromToken log -> Debug. The OIDC CRD type has no IdentityFromToken field today, so this log is operationally irrelevant outside hand-built configs. - Document the single-use contract on tokenResponseRewriter so future contributors do not share an instance across goroutines or reuse it for multiple exchanges. - Strengthen TestTokenResponseRewriter_IdentityFromRawBody so it actually proves the ordering invariant. The previous fixture set the subject path to "authed_user.id", which the rewriter never touches, so the test would pass regardless of ordering. The new fixture uses "token_type", which rewriteTokenResponse unconditionally overwrites to "Bearer" -- the assertion can only hold if extraction ran on the pre-rewrite body. - Rename TestWrapHTTPClientWithMapping_NilMapping to match the renamed wrapHTTPClientForTokenExchange function. - Remove a duplicate RegisterModifiers call in the @upstreamjwt subtest; TestMain registers modifiers once for the package, and a second call races with concurrent reads in parallel subtests. - Add a forged-JWT subtest pinning the no-signature-verification trust-model behavior of @upstreamjwt. A future contributor who adds verification must update the trust model docs and this test. - Rewrite the "unreachable in practice" comment in the priority-1 fallback as defense-in-depth justification. - Add an assert.False(t, identity.Synthetic) check on the IdentityFromToken happy path so a future regression that accidentally sets Synthetic=true here is caught. - Rename "refresh path does not trigger identity extraction" subtest to a name that matches what it actually asserts. --- docs/arch/11-auth-server-storage.md | 37 +- pkg/authserver/upstream/oauth2.go | 162 +++++-- pkg/authserver/upstream/oauth2_test.go | 408 +++++++++++++++++- pkg/authserver/upstream/oidc.go | 23 +- pkg/authserver/upstream/token_exchange.go | 91 +++- .../upstream/token_exchange_test.go | 214 ++++++++- 6 files changed, 853 insertions(+), 82 deletions(-) diff --git a/docs/arch/11-auth-server-storage.md b/docs/arch/11-auth-server-storage.md index b4c21b681e..4198c16b36 100644 --- a/docs/arch/11-auth-server-storage.md +++ b/docs/arch/11-auth-server-storage.md @@ -64,19 +64,46 @@ The storage layer implements multiple interfaces from the [fosite](https://githu - Memory backend: `pkg/authserver/storage/memory.go` - Redis backend: `pkg/authserver/storage/redis.go` -## Synthesis-mode subjects +## Identity resolution for pure OAuth2 providers -OAuth2 upstreams configured without a userInfo endpoint use a fallback identity-resolution mode: the embedded auth server synthesizes a non-PII subject by hashing the upstream access token.

Mirrors the CLI's `thv registry list --refresh` behavior: type-asserts to CachedAPIRegistryProvider and calls ForceRefresh().

OAuth token refresh on infrastructure 4xx (#5170) The OAuth token refresh endpoint returns 4xx for infrastructure events (WAF/firewall blocks, rate limits, transient bad-config deploys) as well as for OAuth protocol failures. Today every 4xx is treated as a permanent auth failure, killing the workload until manual re-authentication. A momentary VPN flap that routes a refresh request through a non-allowlisted IP is enough to leave the workload dead. Treat 4xx responses that lack a structured RFC 6749 error code as transient; only 4xx with a populated error code (invalid_grant, invalid_client, etc.) remains permanent. 429 is always transient per HTTP standard.

The CLI OAuth flow at pkg/auth/discovery::PerformOAuthFlow used to call oauthproto.RegisterClientDynamically directly, so it did not inherit the review-property behaviours added during #5042 (S256 PKCE gating, RFC 7591 §3.2.1 expiry-driven refetch, bearer-token transport with redirect refusal, panic recovery, singleflight deduplication). This commit routes that call site through the shared pkg/auth/dcr resolver introduced in sub-issue 4a (PR #5198) and pins the invariant with a CI grep guard. Profile-neutral resolver input: pkg/auth/dcr now exposes a Request struct that carries exactly the fields the resolver reads (issuer, redirect URI, scopes, discovery URL or registration endpoint, optional explicit endpoint overrides, initial access token, client name, public-client flag). ResolveCredentials takes a Request and no longer imports authserver / upstream domain types. The embedded-authserver adapter helpers (needsDCR, consumeResolution, applyResolutionToOAuth2Config) move to pkg/authserver/runner/dcr_adapter.go where they belong by ownership. CLI persistence model: option (b) from the issue. The resolver runs against an in-memory dcr.CredentialStore scoped to one PerformOAuthFlow invocation. Cross-invocation persistence is handled outside the resolver by pkg/auth/remote/handler.go's existing CachedClientID / CachedClientSecretRef fields, which already preserved cross-invocation reuse and continue to do so unchanged. Wrapping the secretProvider into a CredentialStore adapter (option (a)) was rejected as out-of-scope churn — the existing remote-handler caching is sufficient. PublicClient flag: a new bool on dcr.Request tells the resolver to register as a public PKCE client (token_endpoint_auth_method=none). The S256 gate still fires — the CLI surfaces a clear resolver error rather than silently downgrading when upstream advertises only "plain". Invariant guard: Taskfile target check-dcr-isolation (wired into task lint) and a matching CI step in .github/workflows/lint.yml fail if oauthproto.RegisterClientDynamically is referenced anywhere outside pkg/auth/dcr or pkg/oauthproto. Tests added for the CLI's inherited properties (S256 gating, redirect refusal, singleflight deduplication) in pkg/auth/discovery/dcr_resolver_test.go. The fallback error message for upstreams that omit registration_endpoint is preserved verbatim and pinned by TestHandleDynamicRegistration_MissingRegistrationEndpoint. Closes #5145. * Address code review feedback Fixed issues from code review: - MEDIUM: Rewrote TestResolveSecret / TestResolveSecretWithEnvVar doc comments so they no longer point at the deleted dcr-package twin; the runner-side resolveSecret is now described as the single authoritative implementation. - MEDIUM: Documented the redundant discovery fetch in resolveDCRCredentials as an acknowledged trade-off (the S256 PKCE gate needs code_challenge_methods_supported, which AuthServerInfo does not carry). Threading that field through AuthServerInfo is the natural follow-up. - MEDIUM: Rewrote the dcr.Request.Issuer field doc to spell out what each consumer puts there and why the cache key cannot collide between the embedded authserver and CLI consumers. Added a matching call-site comment in resolveDCRCredentials. - MEDIUM: Introduced dcr.CloseableCredentialStore (embeds CredentialStore + io.Closer). NewInMemoryStore now returns it, so the CLI's defer store.Close() is compile-time safe — no more anonymous-interface type-assertion that would silently no-op on a future refactor. - MEDIUM: Reconciled the CLI flow's "expiry refetch inheritance" wording with what option (b) actually delivers. The handleDynamicRegistration doc and the dcr_resolver_test.go file-level comment now spell out that cross-invocation expiry handling lives in the remote handler, not the resolver, and that option (a) would close the loop as a follow-up. - LOW: The unreachable "fall back to RegistrationEndpoint-direct path" comment is replaced by an accurate description of when each branch fires. * Address iteration-2 code review feedback Fixed issues from second-iteration review: - MEDIUM: Made dcr.inMemoryStore.Close() idempotent via sync.Once. storage.MemoryStorage.Close() closes a channel and is NOT itself idempotent — the previous wrapper inherited that defect through an incorrect doc comment ("Safe to call multiple times"). The wrapper now delivers what the comment claims: a second Close returns the captured error from the first call rather than panicking on "close of closed channel". Pinned by TestInMemoryStore_CloseIsIdempotent and TestInMemoryStore_CloseIsIdempotentUnderRace (8 concurrent callers). - MEDIUM: Dropped the embedded storageBackedStore from inMemoryStore so the type holds a single *storage.MemoryStorage handle instead of two parallel handles (one via embedded interface, one concrete) that required a manual "keep these two in sync" invariant. Get and Put are implemented directly on inMemoryStore, delegating to s.mem — three lines each, structurally guaranteed to share a backend with Close. Pinned by TestInMemoryStore_PutGetCloseShareBackend, TestInMemoryStore_PutRejectsNilResolution, and TestInMemoryStore_GetMissingKeyReturnsMissTuple. * Drop CI guard against direct RegisterClientDynamically calls The Taskfile check-dcr-isolation grep guard and its workflow counterpart added extra surface area to enforce an architectural invariant. Removing both per reviewer preference; the resolver boundary remains enforced by code review alone. * Tighten DCR resolver defense-in-depth from PR review Addresses stacklok/toolhive#5250 review comments: - MEDIUM pkg/auth/dcr/resolver.go (3221902433): include PublicClient in storage.DCRKey, flightKeyOf, and the Redis key serialisation so public and confidential registrations cannot share a cache entry under any Issuer/RedirectURI/ScopesHash collision. - MEDIUM pkg/auth/dcr/resolver.go (3221902453): apply validateUpstreamEndpointURL to explicit authorization_endpoint / token_endpoint overrides; propagate the error via dcrStepMetadata. - MEDIUM pkg/authserver/runner/dcr_adapter.go (3221902473): add a tripwire test that pins the two-call invariant — calling only consumeResolution must leave the built upstream.OAuth2Config's ClientSecret empty. - MEDIUM pkg/authserver/storage/types.go (body): rewrite DCRKey.Issuer doc to describe both consumer profiles (embedded authserver's own issuer vs CLI's upstream issuer) and the cache-key non-collision invariant. - MEDIUM pkg/auth/dcr/resolver.go (body): extend queryStrippingPattern / SanitizeErrorForLog to also match redis(s):// URLs; covers the persistent CredentialStore error-chain surface on the embedded-authserver path. - LOW pkg/auth/discovery/discovery.go (3221902485): log the store.Close() error at debug instead of dropping it; rationale in the deferred-Close block. - LOW pkg/authserver/runner/dcr_adapter_test.go (3221902504): add an env-var case to TestNewDCRRequest pinning the InitialAccessTokenEnvVar wiring end-to-end. * Fix spell-check failure on "Get's" in store_test.go The doc comment for TestInMemoryStore_PutRejectsNilResolution used a possessive apostrophe where the plain noun is correct. * Drop PublicClient from DCR cache and flight keys The original PublicClient-in-keys fix was defense-in-depth against a collision that today's two consumers cannot reach: the embedded authserver registers on AS-origin redirect URIs and the CLI registers on RFC 8252 loopback redirect URIs, and the two address spaces are disjoint. RedirectURI alone separates the public-client and confidential-client profiles at both the persistent-cache and singleflight layers. Encoding PublicClient additionally would invalidate every existing Redis-cached entry across a deployment without buying additional protection. Drop it from DCRKey and flightKeyOf and document the RedirectURI-disjointness invariant alongside the migration condition for a hypothetical future consumer that brings the two address spaces into collision. * Correct stale DCR doc comments from PR review Addresses stacklok/toolhive#5250 review comments: - LOW pkg/auth/discovery/discovery.go (3233521790): handleDynamicRegistration claimed HasCachedClientCredentials enforces cross-invocation expiry, but the gate only checks CachedClientID != "" and does not consult CachedSecretExpiry.

This matters in particular for the enterprise flow where an external controller rewrites the authz ConfigMap when Cedar policies change. Add a Watches entry on corev1.ConfigMap with: * a mapper that lists VirtualMCPServers in the ConfigMap's namespace and enqueues those whose AuthzConfig.Type is "configMap" and whose ConfigMap.Name matches the changed object * a predicate that admits Create and Delete events unconditionally and Update events only when .Data or .BinaryData actually changed, so metadata-only updates (labels, annotations, resourceVersion bumps) do not trigger reconciliation The watch is functionally meaningful only once #5208 lands and the converter actually resolves ConfigMap-sourced policies; until then the re-reconcile still produces an empty-policy config. Wiring it now unblocks that follow-up without an extra round trip.

Split into two parallel matrix entries using the existing `lifecycle` label on api_workload_lifecycle_test.go: - api-workloads: CRUD/validation specs (api-workloads && !lifecycle) - api-workloads-lifecycle: lifecycle ops (api-workloads && lifecycle) Both entries get a 25m per-entry budget via a new test_timeout matrix field (all other entries default to 15m unchanged). Running in parallel, the effective wall-clock time is set by the heavier lifecycle half, not the combined total.

charset=UTF-8 Content-Transfer-Encoding: 8bit Some OAuth2 upstream providers do not expose a usable userinfo endpoint but include user identity in the token response itself (e.g. Slack's `authed_user.id`, or Snowflake's `username` reachable via the gjson `@upstreamjwt` modifier on the embedded access token). Add an `identityFromToken` block on `OAuth2UpstreamConfig` that lets operators map subject, name, and email to gjson dot-notation paths into the token-endpoint response body. The new type lives alongside `TokenResponseMapping` and `UserInfoConfig`; doc comments cross-reference the blocks so operators can find the right one for their provider. The trust-model warning lives both on the `IdentityFromTokenConfig` type and inline on `SubjectPath` so it surfaces in the field-by- field reference (kubectl explain, generated API docs): claims read from the token response are trusted only via TLS, not cryptographically verified — prefer OIDC ID tokens when verifiable claims are required. The same caveat applies to the `@upstreamjwt` modifier, which performs no signature verification. Subject uniqueness is scoped to the upstream provider entry; use distinct providers for distinct trust domains. Admission validation: - SubjectPath: required, MinLength=1, MaxLength=256. - NamePath, EmailPath: optional, MinLength=1, MaxLength=256 (omit the field rather than setting it to an empty string). - Reconcile-time: a new `validateOAuth2UpstreamConfig` helper rejects empty SubjectPath when the block is set, with errors scoped to `oauth2Config[.field]` so callers wrap with their own outer scope — matching the contract of `ValidateOAuth2DCRConfig`. Coexistence with `UserInfo` and `TokenResponseMapping` is allowed at admission; runtime priority is decided by the embedded auth server in a later commit. `SyntheticIdentityUpstreams()` — the predicate driving the `ConditionTypeIdentitySynthesized` advisory — now also skips upstreams configured with `IdentityFromToken`. Identity extracted from the token response is real, not synthesized, so it does not warrant the synthesis advisory. The condition godoc and reason comments are updated to match. This is a partial step toward #5159; the full work (runtime WARN, controller condition messages, reason-constant rename, parity tests) lands in a follow-up. `VirtualMCPServer` CRD regenerates because both resources embed `EmbeddedAuthServerConfig`; the field is usable in either context wherever an OAuth2 upstream is configured. Runtime parsing of `IdentityFromToken` from the token response lands in a later commit; this commit covers the CRD surface plus the controller-side synthesis-predicate update.

After 10 cycles the manager logs "failed to restart after max attempts, giving up" and the workload stays offline until manually restarted, even though the original cause was transient. Track the duration of each runner.Run call. If the workload ran past a stable threshold before failing, treat the next attempt as a fresh failure rather than a continuation of the current retry sequence: reset the attempt counter and backoff delay. This preserves the budget's role as a bound on tight crash loops while allowing recovery from sustained external disturbances. Add a small testability seam (runner factory on DefaultManager, defaulting to runner.NewRunner) so the retry loop has unit-test coverage of the boundary cases. Fixes #5171 Co-authored-by: Claude Opus 4.7 Signed-off-by: Greg Katz * Use functional options for retry test injection Replace direct struct-field assignment in tests with an unexported managerOption type and two helper functions (withRetryConfig and withRunnerFactory). The struct fields stop advertising test-only intent in their comments; the options carry that intent now. Also rewrite the retry loop with an explicit attempt counter so the reset and increment paths do not rely on the for-clause's implicit increment.

The external tool intentionally does not support per-CRD feature gating, so the chart now exposes a single crds.install boolean instead of per-component flags (crds.install.server / .registry / .virtualMcp). Pinned to commit a736420b — no tagged release exists yet; swap for a tag when one is cut. Co-Authored-By: Claude Opus 4.7 (1M context) * Remove controller feature flag gating from operator The ENABLE_SERVER / ENABLE_REGISTRY / ENABLE_VMCP env vars added in #3093 let chart consumers selectively start controller groups. We have no remaining use case for partial controller installs — the chart now ships all CRDs together, and the operator should match. - Drop feature flag constants, dependency map, and isFeatureEnabled helper from main.go; setupControllersAndWebhooks now calls each setup helper unconditionally. - Delete main_test.go (only tested the removed helper). - Drop operator.features.{server,registry,virtualMCP} from values.yaml and the corresponding ENABLE_* env vars from the Deployment template. - Regenerate operator chart README via helm-docs.

Barr Date: Fri, 15 May 2026 03:46:58 -0400 Subject: [PATCH 166/291] Add GitHub Copilot CLI as a supported MCP client (#5287) Copilot CLI reads MCP server entries from ~/.copilot/mcp-config.json using the standard mcpServers map. Register it with type "http" for streamable HTTP and SSE for the legacy transport, matching the behaviour we already use for VS Code and Cursor.

Two translation points mirror the existing TokenResponseMapping plumbing: * cmd/thv-operator/pkg/controllerutil/authserver.go CRD v1beta1.IdentityFromTokenConfig -> authserver.IdentityFromTokenRunConfig (operator path) * pkg/authserver/runner/embeddedauthserver.go authserver.IdentityFromTokenRunConfig -> upstream.IdentityFromTokenConfig (runtime path) A new IdentityFromTokenRunConfig type lives next to TokenResponseMappingRunConfig in pkg/authserver/config.go. Tests cover the round-trip on both sides and the nil-config case (no spurious allocation). * Register gjson modifiers in embedded auth-server bootstrap IdentityFromToken paths that use the `@upstreamjwt` modifier (e.g. `access_token|@upstreamjwt|sub` for upstreams that embed identity inside a JWS access token) require RegisterModifiers() to run before any extraction. Until now the call lived only in test TestMain functions, so production paths silently no-op'd and operators saw a generic "path not found" error. Add the call near the top of NewEmbeddedAuthServer. Protect the gjson.AddModifier write with a sync.Once so concurrent constructors (parallel test cases, thundering-herd restarts) do not race on the gjson global modifier map. * Regenerate swagger docs

This caused audit events to appear as unknown level and prevented level-based filtering in log pipelines. Changed NewAuditLogger to add a ReplaceAttr function that renders the custom audit level (slog.Level(2)) as "AUDIT" string in JSON output, while preserving the numeric level for internal filtering. Preserves the original design intent of placing audit between INFO and WARN, while making events filterable via level="AUDIT" in LogQL and other query languages. Fixes #4296 Signed-off-by: June Kim Signed-off-by: June Kim * Remove TRIAGE_GRAPH.md from tracked files Internal pipeline metadata should not be committed to the upstream repo. * Address review: explicit type assertion + use NewAuditLogger in test Per @amirejaz review: 1. auditor.go: Replace implicit any-equality (a.Value.Any() == LevelAudit) with an explicit slog.Level type assertion. Defensive against future slog changes that might wrap level attrs differently. 2. auditor_test.go: 'preserves standard log levels' subtest no longer re-implements ReplaceAttr — it now uses NewAuditLogger directly so a regression in the production handler would be caught. Tests WARN (above LevelAudit threshold) since INFO is filtered out before ReplaceAttr runs. * Address lint findings - Rename unused groups param to _ in ReplaceAttr - Replace nil context with context.TODO() in test --------- Signed-off-by: June Kim Signed-off-by: June Kim Co-authored-by: Chris Burns <29541485+ChrisJBurns@users.noreply.github.com> --- pkg/audit/auditor.go | 12 ++++++++++++ pkg/audit/auditor_test.go | 38 ++++++++++++++++++++++++++++++++++++++ 2 files changed, 50 insertions(+) diff --git a/pkg/audit/auditor.go b/pkg/audit/auditor.go index b383c63c4d..54cfd8d4b7 100644 --- a/pkg/audit/auditor.go +++ b/pkg/audit/auditor.go @@ -56,6 +56,18 @@ func NewAuditLogger(w io.Writer) *slog.Logger { handler := slog.NewJSONHandler(w, &slog.HandlerOptions{ Level: LevelAudit, + ReplaceAttr: func(_ []string, a slog.Attr) slog.Attr { + // Replace the custom audit level with "AUDIT" string for better + // compatibility with log aggregation systems (Loki, Elasticsearch, etc.) + // that expect standard level names.

This adds a --session-ttl flag to thv run, thv vmcp serve, and the standalone vmcp serve command, and threads it through the runner, transport factory, and all three proxy types (HTTP+SSE, Streamable HTTP, Transparent). Zero means "use the default"; negative values are rejected at the CLI/builder layer. The runner resolves the effective TTL once and passes the non-zero value to both the transport config and Redis storage, so all consumers use the same session lifetime. Co-Authored-By: Claude Sonnet 4.6 * Fix three session timeout bugs in proxy transports Sessions were evicted by the TTL cleanup goroutine even while actively in use because session activity was not being recorded in the right places: 1. SSE keep-alive ticks now call sessionManager.Get to refresh the TTL while the SSE socket is open, so the cleanup goroutine does not evict clients that have not sent a POST request recently. 2. Single notifications/client-responses forwarded via the streamable HTTP proxy now also refresh the session TTL; previously the session header was not read from the request in that code path. 3. Removed ephemeral session creation in the streamable proxy for requests that arrive without an Mcp-Session-Id header. The old code created a UUID-keyed session per request and never cleaned it up, leaking memory over time. Sessionless requests are now routed with an empty sessID that is used only for in-process waiter-channel correlation; no persistent session object is created. Co-Authored-By: Claude Sonnet 4.6 * Make sessionless routing tokens unique to fix response cross-talk Returning sessID="" for sessionless POSTs collapsed concurrent sessionless requests with the same JSON-RPC id onto the same compositeKey("", idKey). The in-process waiters and idRestore sync.Maps silently overwrote, so one client could receive another client's response payload (with the JSON-RPC id rewritten to its own) and the losing client hung until the proxy request timeout. Generate a per-request UUID in resolveSessionForRequest and resolveSessionForBatch when no session header is provided. The token is used solely as an in-process routing key and is not registered with the session manager, so the original memory-leak fix is preserved. Add TestSessionlessConcurrentRequestsAreNotMixed: fires two concurrent sessionless POSTs with the same JSON-RPC id but different methods, with a sync barrier in the fake backend to guarantee both proxy waiters are registered before any response is dispatched. The backend echoes req.Method back so each client can prove it received its own payload, not the other client's. Co-Authored-By: Claude Opus 4.7 (1M context) * Address PR review nits on session TTL Two non-blocking nits from PR #5117 review: session_ttl wire format: time.Duration JSON-marshals as nanoseconds, out of step with sibling duration fields (AccessTokenLifespan, DialTimeout, etc.) that use Go duration strings. A caller sending 7200 expecting seconds would silently get a 7.2 microsecond TTL. Change RunConfig.SessionTTL to string with parsing in Run; the WithSessionTTL builder API still accepts time.Duration so callers are unaffected. uuid.NewRandom in streamable proxy hot path: uuid.New is Must(NewRandom()) and panics on crypto/rand.Read failure. Before this PR it only ran on initialize; the sessionless-routing fix moved it onto every sessionless POST. Switch all three sites to uuid.NewRandom with a controlled 500 on error, matching the existing error-handling pattern after ensureSession.

On loaded CI runners a late goroutine could land after the leader's flight completed and start a fresh flight, producing a second Token() call. The test also relied on beforeEntry/afterEntry hook fields living on the production transientRefresher struct, a pattern prohibited by .claude/rules/testing.md. The same rule applies to newBackOff, also documented as "Nil in production; overridable in tests for fast execution." Replace the 10-goroutine stampede with a 2-goroutine test that verifies the one property we actually own: Refresh uses a constant singleflight key, so a follower joining an in-flight call does not trigger a second Token() invocation. Remove beforeEntry/afterEntry from the production struct, and promote newBackOff from a nil-checked hook to a required constructor parameter: a new newMonitoredTokenSourceWithBackOff constructor takes the factory explicitly, NewMonitoredTokenSource passes the production defaultBackOff, and tests pass fastBackOff. The five test sites no longer mutate refresher fields directly.

Co-Authored-By: Claude Opus 4.7 (1M context) * Extract upstream registry validation helper isValidRegistryJSON and validateRegistryFileStructure duplicated the legacy-format check, JSON unmarshal, and empty-content check, and had drifted on the empty-content message (one said "no servers", the other "no servers or skills").

Every post-initialize MCP call (tools/list, tools/call, ...) therefore reaches the upstream without user-configured headers, leaving features like GitHub Copilot's X-MCP-Toolsets filter silently broken in v0.27.2. Construct a single secrets.EnvironmentProvider at connector build time, plumb it into createMCPClient, and wrap the shared chain with BuildHeaderForwardTripper as the outermost stage so vMCP auth/identity headers still win on overlapping names. Export the existing helper from pkg/vmcp/client so the session backend can reuse it without duplication. Fixes #5289 * Tighten HeaderForward test coverage and docs Fix the inverted chain-ordering comments on mcp_session.go's transport chain assembly and on headerForwardRoundTripper.RoundTrip. The outermost wrapper runs FIRST on the outbound request, so header-forward injects onto a request without auth/identity headers and the inner stages then overwrite with Set(). The previous wording claimed the opposite. The production behaviour is unchanged; only the doc text moved. Replace headerCapturingBackend with the shared fakeBackend by adding headersByMethod / headersFor and a tools/call handler. This removes a near-duplicate fake server in the session backend tests. Extend the header-forward test to cover overlap precedence (an inner auth stage's value wins on the wire when both sides set the same name) and AddHeadersFromSecret end-to-end via t.Setenv against the env-backed secrets provider. Add a restricted-name rejection case to prove the resolveHeaderForward guard is wired into the session-side connector. Trim diff-narrating comments from the test file: drop the past-tense narrative about which PR fixed what and describe the assertions instead. The issue reference (#5289) is kept on the test docstring. --- pkg/vmcp/headerforward/transport.go | 15 +- .../session/internal/backend/mcp_session.go | 30 ++- .../backend/mcp_session_capabilities_test.go | 30 +++ .../mcp_session_header_forward_test.go | 247 ++++++++++++++++++ .../internal/backend/mcp_session_test.go | 4 +- 5 files changed, 320 insertions(+), 6 deletions(-) create mode 100644 pkg/vmcp/session/internal/backend/mcp_session_header_forward_test.go diff --git a/pkg/vmcp/headerforward/transport.go b/pkg/vmcp/headerforward/transport.go index 8bac2cf500..e235fcb17a 100644 --- a/pkg/vmcp/headerforward/transport.go +++ b/pkg/vmcp/headerforward/transport.go @@ -35,9 +35,13 @@ type headerForwardRoundTripper struct { } // RoundTrip injects the pre-resolved headers onto a clone of the request and -// delegates to the wrapped transport.

Replace the local RedisConfig/SentinelConfig/RedisTLSConfig/ACLUserConfig types and the buildTLSConfig/newTLSDialer/configureTLSDialer/validateConfig helpers with toolhive-core/redis.Config and NewClient. NewRedisStorage now takes a tcredis.Config plus the auth-server-specific keyPrefix; the constructor keeps the auth-server invariants (ACL password required, key prefix required) and delegates topology validation, defaults, TLS plumbing, and Ping verification to the shared package. The runner's convertRedisRunConfig now produces a tcredis.Config (ACL credentials resolved from env vars, durations parsed, CA cert file read). Topology checks that duplicated tcredis's Validate were dropped — those errors now surface from the shared package. Tests: delete the storage-side TLS helper tests (now exercising dependency code), trim the validation table down to the auth-server-specific cases, table-drive the three connection-failure tests, remove runner-side topology validation subtests, and update the env-var subtests to the new field layout. Co-Authored-By: Claude Opus 4.7 (1M context) * Return named struct from convertRedisACLConfig Returning (username, password string, error) made it possible to swap the two same-typed values silently at the call site. Introduce an unexported redisACLCredentials struct so the role of each field is visible at the assignment.

The auth-server migration in #5318 demonstrated the pattern for replacing that duplicated code with toolhive-core/redis; vmcp session storage and the proxy-runner session storage are the remaining consumers in this repo. Replace the local RedisConfig/SentinelConfig/RedisTLSConfig types and the validate/build helpers with tcredis.Config and tcredis.NewClient. NewRedisStorage and NewRedisSessionDataStorage now take (ctx, tcredis.Config, keyPrefix, ttl); the constructors keep the session-specific invariants (key prefix required, must end with ':', ttl > 0) and delegate connection-mode validation, timeout defaults, TLS plumbing, and Ping verification to the shared package. NewManagerWithRedis grows the same keyPrefix parameter so the wrapper matches the underlying storage signature. The vmcp server and proxy runner call sites build tcredis.Config in place (Addr, Password, DB) and pass keyPrefix separately; RedisPasswordEnvVar stays in the session package because pkg/runner reads it. Tests: TestValidateRedisConfig is removed (topology checks now live in tcredis); TestNewRedisStorageInvariants replaces it with the session-specific cases (key-prefix and ttl). TestNewRedisStorageACLAuth keeps its coverage but uses the new signature. The "invalid TLS CA cert" manager subtest is dropped (now exercising tcredis code).

Result: any MCPServer that points its session storage at a password-protected Redis fails on connect with "NOAUTH Authentication required". PR #4368 (which introduced the runconfig wiring) explicitly noted in its summary that "the Redis password is intentionally excluded and injected as a pod env var instead". The env-var injection landed for VirtualMCPServer in #4215 / buildRedisPasswordEnvVar but the parallel MCPServer change was never made. This change closes that gap by mirroring the VirtualMCPServer pattern: - Add buildMCPServerRedisPasswordEnvVar in mcpserver_controller.go which returns []corev1.EnvVar with a single SecretKeyRef-backed THV_SESSION_REDIS_PASSWORD entry when sessionStorage.provider == "redis" and passwordRef is set; returns nil otherwise. - Append the helper's output to the proxy container's env slice in the MCPServer reconciler, immediately before user-supplied resourceOverrides.proxyDeployment.env so user overrides can still win on name collisions. - Add TestBuildMCPServerRedisPasswordEnvVar mirroring TestBuildRedisPasswordEnvVar for VirtualMCPServer (nil storage, memory provider, redis without passwordRef, redis with passwordRef). - No CRD changes — the schema already supports passwordRef. Tested: - go build ./cmd/thv-operator/... succeeds - go test ./cmd/thv-operator/controllers/ all green (3.7s) * ci: retrigger after infrastructure-canceled run The previous Tests / Test Go Code job (76080809592) was killed by GitHub Actions infrastructure mid-run ("task: Signal received: \"terminated\"", "runner has received a shutdown signal") ~5.5 min into 'task test-coverage'. No test failures surfaced in the truncated logs.

195/291] Use `events.k8s.io` in registry-api Role (#5340) After #5243, the operator's ClusterRole grants events only in the `events.k8s.io` API group, but the per-MCPRegistry Role builder still requested core `""/events`. Kubernetes RBAC escalation prevention forbids the operator from granting a permission it does not itself hold, so every MCPRegistry got stuck in phase `Failed`. Switch the registry-api Role rule to `events.k8s.io/events` to match the operator's own grant and the controller-runtime events API.

That fresh identity carries upstream tokens transparently refreshed by upstreamtoken.InProcessService.GetAllValidTokens, so overriding it silently re-injected stale upstream access tokens for the entire session lifetime — manifesting as a forced re-auth roughly every 24h. The captured identity is now treated as a fallback: it is injected only when req.Context() carries no identity. This preserves the existing streamable-HTTP Close()/DELETE teardown path (mcp-go constructs that request from context.Background(), which loses the per-request identity) while letting normal backend calls use the freshly refreshed identity from the request context. Closes #5323 * Address code review feedback on identity-propagation fix Fixed issues from code review: - HIGH: Added higher-level regression test exercising the full transport chain against fakeBackend, asserting that a fresh identity placed on the per-request context drives the upstream Authorization header on tools/call while the captured session-init identity authenticates the initialize handshake. Manually verified the test fails under the pre-fix always-override behavior, so it is a true #5323 regression guard. - MEDIUM: Documented the asymmetric health-check handling on the identityRoundTripper doc comment in mcp_session.go (no marker propagation here because health probes do not flow through session-backed clients). - MEDIUM: Clarified that the fallback identity in httpBackendClient is captured per-call (not per-session) and is functionally only required to keep mcp-go's Close() DELETE authenticated; the bug being fixed lives in the persistent-session path. - MEDIUM: Restructured the round-tripper test sections in both client_test.go and roundtripper_test.go: added a block-comment header summarizing the design invariant, grouped tests into Per-request / Fallback / Health-check sub-sections, and renamed *_NoFallback_* tests to *_PerRequestIdentity_* so the canonical path leads with the canonical name. - Lint cleanup: a pre-existing unparam failure on fakeBackend.headersFor was tripped on this branch; resolved by having the new integration test call headersFor with both initialize and tools/call methods. * Address iteration 2 review feedback on identity-propagation fix Fixed issues from iteration 2 code review: - MEDIUM: Added a maintenance-note comment block at the Initialize assertion in mcp_session_identity_refresh_test.go explaining that the block is load-bearing for the unparam linter (keeps fakeBackend.headersFor's `method` parameter genuinely keyed by method) as well as for test documentation. Closes the readability gap a future contributor might trip on if they tried to delete the Initialize block as redundant. Deferred MEDIUM issues filed as follow-ups: - stacklok/toolhive#5333: Consolidate the duplicate identityPropagatingRoundTripper and identityRoundTripper implementations into a shared internal transport package. - stacklok/toolhive#5334: Extend the identity-refresh integration test to wire TokenValidator.Middleware + a fake UpstreamTokenRefresher (AC5 as literally written on #5323). * Consolidate #5323 identity invariant; doc immutability Addresses stacklok/toolhive#5335 review comments: - MEDIUM pkg/vmcp/client/client.go (3268152045): add cross-reference to twin in mcp_session.go and document fallbackIdentity immutability invariant. - LOW pkg/vmcp/session/internal/backend/mcp_session.go (3268152063): add symmetric immutability note on captured fallback pointer. - LOW pkg/vmcp/client/client_test.go (3268152058): replace duplicated "Design invariant" prose with a reference to the canonical location (identityPropagatingRoundTripper in client.go). Apply the same shortening to roundtripper_test.go to eliminate four-way drift risk. * Move unparam shield onto headersFor helper Addresses stacklok/toolhive#5335 review comments: - MEDIUM pkg/vmcp/session/internal/backend/mcp_session_identity_refresh_test.go (3268152036): drop the Initialize-headers assertion and the 7-line "Maintenance note" that propped up the unparam linter. The test now focuses solely on the #5323 regression invariant. The unparam shield moves onto fakeBackend.headersFor itself with a justification that the helper is method-agnostic by design. * Reconcile fallback-scope doc with broader actual behavior Addresses stacklok/toolhive#5335 review comment: - MEDIUM pkg/vmcp/client/client.go (3268152048): the Scope note claimed the fallback was "functionally only required to keep mcp-go's Close() DELETE authenticated", but the code injects on ANY request whose context lacks an identity. Update the comment to honestly describe the broader scope (fallback fires for any context-less request; only Close() exercises that path today) and call out that future code paths dropping identity would be silently authenticated by the captured snapshot unless a method/URL gate is added. --- pkg/vmcp/client/client.go | 120 +++++++++--- pkg/vmcp/client/client_test.go | 113 +++++++++-- .../session/internal/backend/mcp_session.go | 39 +++- .../backend/mcp_session_capabilities_test.go | 6 + .../mcp_session_identity_refresh_test.go | 184 ++++++++++++++++++ .../internal/backend/roundtripper_test.go | 108 ++++++++-- 6 files changed, 514 insertions(+), 56 deletions(-) create mode 100644 pkg/vmcp/session/internal/backend/mcp_session_identity_refresh_test.go diff --git a/pkg/vmcp/client/client.go b/pkg/vmcp/client/client.go index 59baf1fd86..882fe8d810 100644 --- a/pkg/vmcp/client/client.go +++ b/pkg/vmcp/client/client.go @@ -177,31 +177,79 @@ func (f roundTripperFunc) RoundTrip(req *http.Request) (*http.Response, error) { return f(req) } -// identityPropagatingRoundTripper propagates identity and health-check markers to backend HTTP requests. -// This ensures that identity information from the vMCP handler is available for authentication -// strategies that need it (e.g., token exchange). +// identityPropagatingRoundTripper propagates the health-check marker and a +// fallback identity to backend HTTP requests. // -// The health-check marker is stored at transport creation time and re-injected into every -// outgoing request, including the DELETE that mcp-go sends when closing a streamable-HTTP -// session.

Move all pre-Run setup from cmd/thv-operator/main.go (scheme registration, flag parsing, logger init, signal context, manager construction) into a new cmd/thv-operator/app package exposing a single Run() entry point. - Add additive Run() helper to cmd/thv-proxyrunner/app that absorbs the viper env binding, logger init, signal-aware context, and root command execution from cmd/thv-proxyrunner/main.go. - Shrink both main.go files to two-line wrappers that call app.Run(), enabling out-of-tree builds to wrap the binaries via a literal func main() { app.Run() }. This is a mechanical code move with no behavior change. All existing flags, environment variables, exit codes, and signal handling are preserved unchanged. * Apply review polish to operator/proxyrunner refactor Addresses stacklok/toolhive#5332 review comments: - MEDIUM cmd/thv-operator/app/app.go (3267942319): shorten Run() doc; "never returns" was inaccurate (mgr.Start returns nil on clean signal shutdown) and exceeded the project "one short line max" guidance. - MEDIUM cmd/thv-proxyrunner/app/app.go (3267942342): same one-line fix; ExecuteContext returns nil on clean cobra exit. - LOW cmd/thv-operator/main.go (3267942350): restore the package doc sentence ("It sets up and runs the controller manager...") dropped during the original move. - LOW cmd/thv-proxyrunner/app/{entrypoint -> app}.go (3267942360): rename for cross-binary consistency with cmd/thv-operator/app/app.go. --- cmd/thv-operator/app/app.go | 364 +++++++++++++++++++++++++++++++++ cmd/thv-operator/main.go | 356 +------------------------------- cmd/thv-proxyrunner/app/app.go | 45 ++++ cmd/thv-proxyrunner/main.go | 41 +--- 4 files changed, 413 insertions(+), 393 deletions(-) create mode 100644 cmd/thv-operator/app/app.go create mode 100644 cmd/thv-proxyrunner/app/app.go diff --git a/cmd/thv-operator/app/app.go b/cmd/thv-operator/app/app.go new file mode 100644 index 0000000000..4bfb1b52fc --- /dev/null +++ b/cmd/thv-operator/app/app.go @@ -0,0 +1,364 @@ +// SPDX-FileCopyrightText: Copyright 2025 Stacklok, Inc. +// SPDX-License-Identifier: Apache-2.0 + +// Package app contains the entry-point and pre-Run setup for the ToolHive +// Kubernetes Operator.

SSRF check implemented inline to preserve the oauthproto leaf-package invariant (no import of pkg/networking). - pkg/networking/utilities.go: add RFC6598 CGN (100.64.0.0/10) and RFC5737 documentation ranges (192.0.2.0/24, 198.51.100.0/24, 203.0.113.0/24) to the private IP block list. - pkg/networking/http_client.go: add WithDisableKeepAlives option to HttpClientBuilder so callers can prevent keep-alive connection reuse from bypassing per-dial SSRF checks. Co-Authored-By: Claude Sonnet 4.6 (1M context) * Tighten CIMD compliance — URL §3 requirements, auth methods, multicast Verified against both draft-ietf-oauth-client-id-metadata-document and internal RFC-0071: - validateCIMDClientURL enforces §3 URL requirements: non-empty path component, no fragment, no userinfo, no dot-segments; removes the TODO that was deferring this validation to Phase 2 - ValidateClientMetadataDocument rejects symmetric auth methods (client_secret_post, client_secret_basic, client_secret_jwt) per §4.1 of the CIMD draft - Add IPv4 multicast (224.0.0.0/4) and IPv6 multicast (ff00::/8) to both pkg/networking and the oauthproto inline SSRF block list - Update tests to use meaningful URL paths (/metadata.json); bare-root paths (/) now correctly fail the §3 path requirement Note: custom CA cert support (RFC-0071 §4 server-side) is deferred to PR 2 — FetchClientMetadataDocument will accept an optional *http.Client allowing the storage decorator to pass a CA-aware client. Co-Authored-By: Claude Sonnet 4.6 (1M context) * Fix three security issues flagged in Copilot review 1. isLoopbackHTTP bypass: prefix matching (e.g. "http://localhost") matched "http://localhost.evil.com/". Now parses the URL and checks the hostname exactly against loopback addresses. 2. DNS TOCTOU: DialContext resolved the hostname then dialled by name, leaving a window where the second resolution could return a private IP. Now picks the first valid IP, validates it, and dials by IP literal to eliminate the race. 3. Redirect target not validated: CheckRedirect only counted hops. A redirect from HTTPS to HTTP or to a private IP was not caught. Now calls validateCIMDClientURL on each redirect target. Also: - Drop io.Copy drain after decode; keep-alive connections are disabled so draining for connection reuse is unnecessary and would defeat the 10KB cap by reading the remainder of the body - Add clarifying comment that only symmetric auth methods are forbidden; asymmetric methods (private_key_jwt, tls_client_auth, none) are valid - Add tests: localhost subdomain bypass, dial-guard SSRF via HTTPS URL, renamed scheme-check test to accurately describe what it exercises Co-Authored-By: Claude Sonnet 4.6 (1M context) * Move FetchClientMetadataDocument to pkg/oauthproto/cimd sub-package Addresses jhrozek feedback on duplication: - Create pkg/oauthproto/cimd sub-package which may import pkg/networking, eliminating three cases of duplicated logic: 1. validateRedirectURI → now delegates to oauthproto.ValidateRedirectURI with RedirectURIPolicyStrict (RFC 8252 §8.4) 2. isLoopbackHTTP → now uses oauthproto.IsLoopbackHost(parsed.Hostname()) via URL.Parse, closing the localhost.evil.com prefix-match bypass 3. cimdPrivateBlocks/isPrivateForCIMD → now uses networking.IsPrivateIP, eliminating the duplicated IP block list init - pkg/oauthproto/cimd.go retains only ToolHiveClientMetadataDocumentURL and IsClientIDMetadataDocumentURL (Phase 1 code depends on these) - HttpClientBuilder.WithPrivateIPs(false) is not used in newCIMDHTTPClient because it also blocks loopback (127.0.0.0/8), breaking the intentional http://localhost development exception. The custom DialContext is kept but uses networking.IsPrivateIP instead of the duplicated block list. Co-Authored-By: Claude Sonnet 4.6 (1M context) * Use networking.FetchJSON in FetchClientMetadataDocument Follow-up to jhrozek's review of the FetchJSON comment: pkg/networking/fetch.go: - Add WithMaxResponseSize(int64) FetchOption so callers can enforce tighter limits; CIMD uses 10 KB vs the 1 MB default - Fix Content-Type validation bug: old strings.Contains check rejected valid application/*+json subtypes (e.g. ld+json). Replace with mime.ParseMediaType + RFC 6839 prefix/suffix check, which is the same logic CIMD already used correctly pkg/oauthproto/cimd/fetch.go: - FetchClientMetadataDocument delegates to networking.FetchJSON with WithMaxResponseSize(10*1024); removes the manual HTTP fetch loop, body-drain defer, and the now-unused isJSONSubtype helper (~30 lines) Co-Authored-By: Claude Sonnet 4.6 (1M context) * Fix two nits from jhrozek review - CheckRedirect: remove dead code. `len(via) >= 1` fired on the first redirect (via already contains the original request), making the validateCIMDClientURL call unreachable. Per CIMD §4 the AS MUST NOT automatically follow redirects, so simplify to unconditional ErrUseLastResponse with the spec quote in the comment. - validateCIMDClientURL: use parsed.Scheme instead of strings.HasPrefix for the HTTPS check. URI schemes are case-insensitive per RFC 3986 §3.1; HTTPS://example.com/ is valid but the prefix check rejected it with a misleading error. The loopback check already used parsed.Scheme correctly.

Implements changes for issue #5327: - Add ExternalAuthTypeOBO ExternalAuthType = "obo" constant to the CRD types file. CRD enum admission, OBOConfig struct and CEL rule remain out of scope and land in the follow-up CRD-admission task. - Add controllerutil.OBOHandler struct, ErrEnterpriseRequired sentinel, RegisterOBOHandler setter and OBOValidate / OBOSecretEnvVars wrappers to cmd/thv-operator/pkg/controllerutil/tokenexchange.go. Default handler returns ErrEnterpriseRequired from every method. - Add pkg/auth/obo package exporting MiddlewareType = "obo", CreateMiddleware factory variable and RegisterFactory setter. Default factory installs a stub Middleware whose Handler responds 503 with a body explaining the OBO middleware factory has not been registered. - Wire obo.MiddlewareType -> obo.CreateMiddleware into the 17-entry middleware-factory map in pkg/runner/middleware.go. - Add OBOConverterStub to pkg/vmcp/auth/converters and register it as the built-in StrategyConverter for ExternalAuthTypeOBO inside NewRegistry. Every method returns an error wrapping ErrEnterpriseRequired so callers can match it via errors.Is. - Add no-op case ExternalAuthTypeOBO arms to existing switches on ExternalAuthType (Validate, AddExternalAuthConfigOptions, getExternalAuthConfigSecretEnvVar) to keep the exhaustive linter green. These arms preserve the existing default behavior; the actual dispatch wiring lives in the follow-up task. - Add unit tests covering every default stub behavior, last-write-wins semantics for both setters and the registered-converter lookup. * Address code review feedback Fixed issues from code review: - HIGH: Lead each new case ExternalAuthTypeOBO arm comment with an explicit "Minimal no-op arm added to satisfy the exhaustive linter; dispatch wiring lands in follow-up task #5328" so reviewers see the scope rationale next to the code rather than only in the PR body. - HIGH: Wrap ErrEnterpriseRequired from the OBO arm of AddExternalAuthConfigOptions ("obo dispatch not yet wired: %w") so callers can use errors.Is to distinguish "type known but not wired" from a genuinely unknown auth type. - MEDIUM: Add a TODO(#5329) marker on validateTypeConfigConsistency pointing at the biconditional row and the unauthenticated check that must be updated when the CRD admission task introduces OBOConfig. - MEDIUM: Add OBOApplyRunConfig wrapper to symmetrize the public surface alongside OBOValidate and OBOSecretEnvVars, plus a sibling unit test covering the default sentinel path and dispatch through a registered handler. - MEDIUM: Add TestGetSupportedMiddlewareFactories_OBORegisterBeforeConstruction in pkg/runner/middleware_test.go that locks down the "register before construction" contract for obo.CreateMiddleware — a factory swapped before GetSupportedMiddlewareFactories runs must be the one captured in the returned map. * Regenerate CRD reference docs for ExternalAuthTypeOBO Adds the new "obo" external auth type entry to docs/operator/crd-api.md so the docs match the constant introduced in cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go. Output of "task crdref-gen". Co-Authored-By: Claude Opus 4.7 (1M context) * Move OBO sentinel to pkg/auth/obo; address review hygiene Addresses stacklok/toolhive#5338 review comments: - MEDIUM pkg/auth/obo/middleware.go (3270092569): clarify stubMessage doc comment — the constant is unexported and shared with same-package tests. - MEDIUM pkg/vmcp/auth/converters/obo.go (3270092576): move ErrEnterpriseRequired from cmd/thv-operator/pkg/controllerutil to pkg/auth/obo so vmcp converters no longer import operator internals. - MEDIUM cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go (3270092583): existing TODO already covers the biconditional + the unauthenticated check; refine the OBO Validate() arm wording to make the contract (delegated to the controllerutil layer, CRD-level Validate stays a no-op) explicit. - LOW pkg/vmcp/auth/converters/obo.go (3270092595): rename OBOConverterStub -> OBOConverter for parity with sibling converters (TokenExchangeConverter, AwsStsConverter, ...). - LOW pkg/auth/obo/middleware_test.go (3270092599): replace the body-substring OR with an exact-equal check against stubMessage+"\n", locking the cross-file contract. - LOW cmd/thv-operator/pkg/controllerutil/tokenexchange.go (3270092604): drop the developer-instruction prose from ErrEnterpriseRequired's user-visible message; the registration instruction now lives in the Go doc comment, where it belongs. - LOW cmd/thv-operator/pkg/controllerutil/tokenexchange.go (3270092611): normalize TODO(#5328) format across the three sites referencing the dispatch-wiring follow-up so `git grep TODO\(#5328\)` finds them all. Co-Authored-By: Claude Opus 4.7 (1M context) * Synchronize OBO registration sites; panic on partial registration Addresses stacklok/toolhive#5338 review comments: - MEDIUM cmd/thv-operator/pkg/controllerutil/tokenexchange.go (3270092563): guard the package-level OBO handler with a sync.RWMutex so a future hot-reload or admission-webhook re-registration cannot race in-flight dispatch reads. All wrapper reads now snapshot the handler under RLock; RegisterOBOHandler takes the write lock. - MEDIUM pkg/auth/obo/middleware.go (3270092580): turn CreateMiddleware into a stable redirector backed by a mutex-protected currentFactory. The "captured at runner-construction time" caveat no longer applies — every CreateMiddleware call reads the current factory under RLock — and the doc comment is rewritten to match the new semantics. Adds obo.DefaultFactory so external test code can restore the package default in a t.Cleanup. The pkg/runner contract test is updated to exercise the call-after-register path that was previously unreachable. - MEDIUM cmd/thv-operator/pkg/controllerutil/tokenexchange.go (3270092585): RegisterOBOHandler now panics if any of the three function fields is nil. A partial registration would have nil-derefed deep inside dispatch at reconcile time, far from the call site; surfacing the problem at init() is easier to diagnose. Sibling fix in obo.RegisterFactory rejects a nil factory the same way.

Co-Authored-By: Claude Opus 4.7 (1M context) * Declare obo.CreateMiddleware as func, not var Matches the sibling middleware packages (awssts, upstreamswap, oauthproto/tokenexchange) and makes RegisterFactory the single mutation path — direct assignment to CreateMiddleware is no longer possible. The redirector body is unchanged: every call still reads currentFactory under the package RWMutex, so out-of-tree builds that registered a factory continue to see their factory dispatched to.

From 2894982180949e03f9504d176605433e705a84b1 Mon Sep 17 00:00:00 2001 From: Trey Date: Wed, 20 May 2026 09:56:26 -0700 Subject: [PATCH 200/291] Inject spawn seam in RunWorkloadDetached to stop orphan test processes (#5346) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Inject spawn seam in RunWorkloadDetached DefaultManager.RunWorkloadDetached re-execs os.Executable() with `start --foreground`. Under `go test`, os.Executable() resolves to the test binary, so the unit test for updateSingleWorkload spawned `workloads.test start test-workload --foreground` as a detached child via Setsid. Go's testing.Main ignores the positional args and re-ran the entire test suite, which called RunWorkloadDetached again — recursive spawn. Each child was orphaned to launchd/init and survived after the test binary exited, eventually consuming high CPU on developer machines. Extract the spawn step into a function-typed field on DefaultManager (detachedProcessSpawner) with a withDetachedSpawner option, following the same pattern as withRetryConfig and withRunnerFactory. Production uses spawnDetached (unchanged behavior); tests inject a no-op spawner that returns a fake PID. Closes #5344 * Address review feedback on spawn seam - MEDIUM: Preserve original WorkloadStatus ordering. Move SetWorkloadStatus(Starting) and the Error rollback into spawnDetached, so failures during pre-exec setup (os.Executable, xdg.DataFile, GetSecretsPassword) return without any status change — matching the pre-refactor behavior. - MEDIUM: Add TestDefaultManager_RunWorkloadDetached_SpawnerError to cover the new spawner-error path. - MEDIUM: Add TestDefaultManager_RunWorkloadDetached_SpawnerSuccess to verify the spawner is invoked and its PID is forwarded. - LOW: Document that ctx is intentionally not propagated to exec.Command, so the child can outlive the parent. - LOW: Expand detachedProcessSpawner doc to call out the platform-specific detachment that makes orphan children possible. --- pkg/workloads/manager.go | 98 ++++++++++++++++++++++++++--------- pkg/workloads/manager_test.go | 90 +++++++++++++++++++++++++++++++- 2 files changed, 162 insertions(+), 26 deletions(-) diff --git a/pkg/workloads/manager.go b/pkg/workloads/manager.go index 67cc8057d1..aa2e0eb442 100644 --- a/pkg/workloads/manager.go +++ b/pkg/workloads/manager.go @@ -98,8 +98,9 @@ type DefaultManager struct { statuses statuses.StatusManager configProvider config.Provider - retryConfig *retryConfig - newRunner mcpRunnerFactory + retryConfig *retryConfig + newRunner mcpRunnerFactory + detachedSpawner detachedProcessSpawner } // mcpRunner is the subset of *runner.Runner that RunWorkload's retry loop @@ -112,6 +113,16 @@ type mcpRunner interface { // mcpRunnerFactory constructs an mcpRunner for one attempt of the retry loop. type mcpRunnerFactory func(*runner.RunConfig, statuses.StatusManager) mcpRunner +// detachedProcessSpawner starts the detached process that backs +// RunWorkloadDetached and returns its PID.

The same option was missing from `thv registry login`, and even via the Go API the boolean was hardcoded to false one layer down — so an operator using `thv registry login --registry http://10.x.y.z/...` to register and authenticate in one step always hit the private-IP rejection regardless of intent. - LoginOptions: add AllowPrivateIP. - ensureRegistryURL: thread it into DetectRegistryType and the SetRegistryAPI / SetRegistryURL calls (which were `false` literals). - registry_login.go: add -p/--allow-private-ip mirroring the flag on set-registry. No behavior change for callers that leave the new field at its zero value.

These are mostly speculative API surface (builder options, functional options, convenience constructors) and stale test scaffolding that no caller exercises. Highlights: - pkg/api/server.go: drop 7 unused ServerBuilder.With* options and the standalone Serve helper - pkg/json/any.go: drop NewData/MustParse/FromRawExtension/ MapFromRawExtension convenience constructors - pkg/state/runconfig.go: drop ReadRunConfigJSON, LoadRunConfigOfType, LoadRunConfigWithFunc, and the now-orphaned RunConfigReadJSONFunc type - pkg/vmcp/composer/workflow_errors.go: drop unused WorkflowError type; keep package-level sentinels and ValidationError - Trim unused test helpers in cmd/thv-operator/test-integration/ mcp-registry/, test/e2e/, and test/integration/authserver/helpers/ - Remove imports orphaned by deletions Excludes cmd/thv/app/ui/ dead code (kept intentionally, may be revived for a TUI). ~1,176 LOC removed across 38 files. `task build` and `task test` pass.

Authorization servers that serve their RFC 8414 metadata exclusively at the path-insertion URL (scheme://host/.well-known/oauth-authorization-server/{path}) — such as Gleean's AS with issuer https://example.com/oauth — received a 404 or HTML response and the CLI failed with "unexpected content-type text/html" before opening the browser. Replace the single-URL construction with oauthproto.FetchAuthorizationServerMetadata, which tries the three well-known URL forms in priority order (RFC 8414 path-insertion, OIDC issuer-suffix, bare RFC 8414), restoring the fallback behaviour that existed in v0.27.x via discoverOIDCEndpointsWithClientAndValidation. The fetched code_challenge_methods_supported is forwarded to the resolver through a new dcr.Request.CodeChallengeMethodsSupported field, so the S256 PKCE gate fires without a second discovery round-trip inside the resolver. Regression test added: TestHandleDynamicRegistration_NonRootIssuerRFC8414PathInsertion mounts metadata only at /.well-known/oauth-authorization-server/oauth and verifies DCR succeeds end-to-end. Co-Authored-By: Claude Sonnet 4.6 (1M context) * Add coverage for CodeChallengeMethodsSupported field and synthesis path Three gaps in the test suite left by the #5356 fix: 1. pkg/auth/dcr: TestResolveDCRCredentials_CodeChallengeMethodsSupportedFieldEnablesPublicClient pins the new Request.CodeChallengeMethodsSupported field on the RegistrationEndpoint-direct branch. Without a DiscoveryURL the S256 gate has no metadata to read from; the field is the only input. Four cases: S256 allows public client, plain rejects, absent rejects, absent is fine for confidential clients. 2. pkg/auth/discovery: TestHandleDynamicRegistration_PreDiscoveredPathNonRootIssuer covers the pre-discovered path (config.RegistrationEndpoint/AuthorizeURL/ TokenURL all pre-set) with a non-root issuer. getDiscoveryDocument short-circuits on this path and returns a synthesised document with empty code_challenge_methods_supported; the multi-URL re-fetch in resolveDCRCredentials must still reach the path-insertion URL correctly. 3. pkg/auth/discovery: TestHandleDynamicRegistration_SynthesisesEndpointWhenMetadataOmitsIt verifies that when FetchAuthorizationServerMetadata returns ErrRegistrationEndpointMissing (valid metadata, no registration_endpoint), resolveDCRCredentials synthesises {issuer}/register and routes the registration there — the nanobot/Hydra convention also applied by the resolver's DiscoveryURL branch.

In upstream-only builds the default handler returns obo.ErrEnterpriseRequired, so the dispatch never falls through to the default arm's generic "unsupported external auth type" error. - Add an OBO branch to MCPExternalAuthConfigReconciler.Reconcile that calls controllerutil.OBOValidate after the existing Validate() succeeds. errors.Is(err, obo.ErrEnterpriseRequired) maps to Reason=EnterpriseRequired; any other error maps to Reason=InvalidConfig. The branch writes status via controllerutil.MutateAndPatchStatus per the operator status-write convention; the existing r.Status().Update call sites are untouched (refactor is out of scope for this task). - Cover each dispatch arm with a fake-client unit test that asserts errors.Is matches obo.ErrEnterpriseRequired and that no "unsupported external auth type" string leaks. A table-driven setInvalid test verifies the reason-string selection handles the sentinel directly, the sentinel through a fmt.Errorf wrap (the vMCP converter path), and any other error. * Address code review feedback on OBO dispatch wiring Fixed issues from code review: - CRITICAL: setInvalid now re-fetches the object via r.Get and re-applies applyIdentitySynthesizedCondition inside the MutateAndPatchStatus closure. Previously the helper diffed against an already-mutated snapshot, so a user switching a config from embeddedAuthServer to obo would leave a stale IdentitySynthesized=True condition lingering on the server. Regression test TestMCPExternalAuthConfigReconciler_OBO_ClearsStaleIdentitySynthesized constructs that scenario and asserts the stale condition is removed alongside the new Valid=False/EnterpriseRequired write. - CRITICAL: Added integration tests under cmd/thv-operator/test-integration/mcp-external-auth/ for the three consumer-CR paths (MCPServer, MCPRemoteProxy, VirtualMCPServer) plus a shared generic-error guard. The VirtualMCPServer test exercises the vMCP DiscoverAndResolveAuth path at pkg/vmcp/auth/converters/interface.go:191 and asserts errors.Is matches the sentinel through the "failed to convert to strategy: %w" wrap, proving the recognition is wrap-safe and not string-prefixed. - MEDIUM: setInvalid's doc comment now describes the re-fetch behavior and why it is required (the snapshot-vs-mutation drop trap). * Consolidate OBO test coverage; add reason constants Fixed issues from second-round code review: - CRITICAL: removed the misnamed fake-client tests from test-integration/mcp-external-auth/ (envtest directory by convention). The unique vMCP wrap-site assertion moved to pkg/vmcp/auth/converters/ as TestDiscoverAndResolveAuth_OBO_SentinelSurvivesWrap — it lives next to the "failed to convert to strategy: %w" wrap site it guards. The dispatch arms remain individually covered by the existing unit tests. - MEDIUM: setInvalid now treats errors.IsNotFound on its re-fetch as a clean no-op exit so a deletion race between the initial Get and the re-fetch does not produce spurious "Reconciler error" log noise. - MEDIUM: added ConditionReasonEnterpriseRequired / ConditionReasonInvalidConfig constants in v1beta1, documented as user-facing contract. The controller and tests now reference the named constants instead of bare string literals. - MEDIUM: documented the double-call between applyIdentitySynthesized Condition at line 95 and setInvalid's patch closure — the in-memory mutation is load-bearing only on the validation-failure and Valid= True paths; setInvalid re-applies the advisory inside its own patch because MutateAndPatchStatus would otherwise drop it. * Address PR review feedback: comment hygiene, test guards, reason-selection test Addresses stacklok/toolhive#5345 review comments: - MEDIUM cmd/thv-operator/controllers/mcpexternalauthconfig_controller_test.go (3275486199 / F2): rework setInvalid_ReasonSelection to drive Reconcile via RegisterOBOHandler so the production errors.Is decision is exercised, not the test's own copy. - LOW cmd/thv-operator/controllers/mcpexternalauthconfig_controller.go (3275486175 / F3): replace stale line-number prose in the Reconcile comment block with behavior-named references. - LOW cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go (F5): strip the leftover TODO(#5328) prefix from the Validate() OBO arm; keep the load-bearing WHY content. - LOW cmd/thv-operator/controllers/mcpexternalauthconfig_controller_test.go (3275486186 / F6): add a positive condition.Message assertion so a refactor that empties the sentinel message would fail the test. - LOW cmd/thv-operator/pkg/controllerutil/tokenexchange_test.go (3275486215 / F7a): add the "unknown middleware type" generic-error guard. - LOW cmd/thv-operator/controllers/virtualmcpserver_externalauth_test.go (3275486203 / F7b): add both generic-error guards to bring the test into uniformity with the AC and the sibling tests. - LOW cmd/thv-operator/pkg/controllerutil/tokenexchange.go (3275486211 / F9): drop the "Called from ..." caller-naming clause from OBOApplyRunConfig's doc comment per go-style.md. - LOW cmd/thv-operator/controllers/mcpexternalauthconfig_controller.go (3275486192 / F10): document the load-bearing nature of the re-invoked applyIdentitySynthesizedCondition inside setInvalid's closure, naming the regression test that guards it. * Add typed OBO error contract: ValidationError + transient triage Addresses stacklok/toolhive#5345 review comment 3277320814: - pkg/auth/obo: add ValidationError (Message string, Error() returns it verbatim) following the SpecValidationError precedent in the operator. Document the OBOHandler error contract on the obo package errors file and on the OBOHandler type doc comment in controllerutil: callers triage errors into three buckets — errors.Is(ErrEnterpriseRequired) → permanent EnterpriseRequired; errors.As(*obo.ValidationError) → permanent InvalidConfig with the typed Message exposed verbatim; anything else → transient, reconciler returns the error so controller-runtime requeues with backoff. - cmd/thv-operator/controllers: extract the OBO branch into a triageOBOValidation helper so Reconcile stays under the gocyclo threshold; helper implements the three-way triage. The transient bucket is the new behavior — previously any non-sentinel error mapped to InvalidConfig permanently, locking the resource on a transient I/O blip until the user touched the spec. - Simplify setInvalid to return just error (the result was always the zero ctrl.Result), and have triageOBOValidation construct the result. - Replace the table-driven setInvalid_ReasonSelection test with OBO_ErrorTriageInReconcile, which adds two ValidationError cases (bare + wrapped through fmt.Errorf) and asserts the transient bucket returns the error from Reconcile and writes NO condition. - pkg/auth/obo: add ValidationError_ErrorAndAsThroughWrap test asserting Error() returns the Message verbatim, errors.As matches the typed error through a fmt.Errorf wrap, and errors.Is does NOT confuse a ValidationError with the EnterpriseRequired sentinel. No migration concern — no enterprise OBO handler exists upstream yet, so locking the contract before that PR lands is free. --- .../v1beta1/mcpexternalauthconfig_types.go | 33 +- .../mcpexternalauthconfig_controller.go | 113 +++++++ .../mcpexternalauthconfig_controller_test.go | 294 ++++++++++++++++++ .../virtualmcpserver_deployment.go | 21 +- .../virtualmcpserver_externalauth_test.go | 46 +++ .../pkg/controllerutil/tokenexchange.go | 52 +++- .../pkg/controllerutil/tokenexchange_test.go | 54 ++++ pkg/auth/obo/errors.go | 32 ++ pkg/auth/obo/errors_test.go | 30 ++ pkg/vmcp/auth/converters/obo_test.go | 53 ++++ 10 files changed, 700 insertions(+), 28 deletions(-) diff --git a/cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go b/cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go index a4e823ac14..0aefd93764 100644 --- a/cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go +++ b/cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go @@ -1026,6 +1026,23 @@ const ( ConditionReasonIdentitySynthesizedInactive = "AllUpstreamsHaveUserInfo" ) +// Condition reasons for ConditionTypeValid on OBO-typed configs.

The vmcp binary's `AuthzConfig` validator only accepts `cedar` or `none`, so the pod crashed in `CrashLoopBackOff` at startup. Inline authz also silently dropped `GroupClaimName`, `RoleClaimName`, `GroupEntityType`, and `EntitiesJSON`, so any enterprise Cedar policy that walked a `Client → ClaimGroup → PlatformRole` hierarchy denied every request because the runtime Cedar authorizer built `THVGroup::` parents while the entity store contained `ClaimGroup::` entities. Wire the configMap path end-to-end, plumb the four missing fields through both source paths, and move `PrimaryUpstreamProvider` onto the auth server config where it belongs: * Extract `LoadAuthzConfigFromConfigMap` as the shared fetch/parse/ validate helper in `controllerutil`; `AddAuthzConfigOptions` now delegates to it. The vMCP converter calls the same helper so the failure modes match the `MCPServer`/`MCPRemoteProxy` runner path. * Extend `pkg/vmcp/config.AuthzConfig` with `EntitiesJSON`, `GroupClaimName`, `RoleClaimName`, `GroupEntityType`, and forward all four into `cedar.ConfigOptions` in the Cedar middleware factory. `EntitiesJSON` defaults to `"[]"` when unset to preserve the historical Cedar contract. * Lift the source-agnostic Cedar JWT-claim mapping fields (`GroupClaimName`, `RoleClaimName`, `GroupEntityType`) onto `AuthzConfigRef` so they work identically for inline and configMap users. For configMap users the parsed payload provides the default and the spec-level field overrides when set. * Move `PrimaryUpstreamProvider` onto `EmbeddedAuthServerConfig` (`spec.authServerConfig.primaryUpstreamProvider` on `VirtualMCPServer`). The field describes which upstream IDP token Cedar reads claims from, which is a property of the embedded auth server, not of the authz policies. Placing it next to `upstreamProviders` co-locates the choice with the set it selects from. Reachable from `MCPExternalAuthConfig` of type `embeddedAuthServer` as well; on `MCPServer`/`MCPRemoteProxy` (single-upstream consumers) the only validated values are empty (auto-select) or the name of that single upstream. The legacy `spec.incomingAuth.authzConfig.inline.primaryUpstreamProvider` location is read as a backward-compatibility fallback for one release with a `Warning` event of reason `AuthzPrimaryUpstreamProviderDeprecated`. * Pre-validate the referenced authz `ConfigMap` in the controller and distinguish `NotFound` from other parse/validation failures via two condition reasons on `AuthConfigured`: the existing shared `AuthzConfigMapNotFound` and a new `AuthzConfigMapInvalid`. This mirrors the diagnostic `MCPRemoteProxy` emits today and gives users a status-level error before the converter fails opaquely. * Validate the resolved `PrimaryUpstreamProvider` (from either source) against the declared embedded auth server upstreams so an unresolvable provider is rejected at convert time. CRD compatibility: not a breaking change. The legacy `spec.incomingAuth.authzConfig.inline.primaryUpstreamProvider` location continues to work, with a Warning event emitted whenever it is read; planned removal one release after the deprecation cycle. The new fields on `AuthzConfigRef` (`GroupClaimName`, `RoleClaimName`, `GroupEntityType`) and on `EmbeddedAuthServerConfig` (`PrimaryUpstreamProvider`) are additive. Closes #4919 Closes #5208 Closes #5277 * Lock test coverage for `primaryUpstreamProvider` paths The relocation of `PrimaryUpstreamProvider` onto `EmbeddedAuthServerConfig` in the parent commit introduced two new behaviours and surfaced one pre-existing coverage gap. None of the three were captured by a test. Add focused unit tests that pin each behaviour so a future refactor cannot silently drop it. * `*VirtualMCPServer.ExplicitPrimaryUpstreamProvider()` is the central precedence helper: canonical `spec.authServerConfig.primaryUpstreamProvider` wins, deprecated `spec.incomingAuth.authzConfig.inline.primaryUpstreamProvider` is the fallback, otherwise empty. A unit test covers all four combinations (canonical only, deprecated only, both, neither) and locks the `fromDeprecated` flag the caller uses to gate the deprecation event. * `AuthzConfigRef.DeprecatedInlinePrimaryUpstreamProvider()` is the helper the advisory paths on `MCPServer` and `MCPRemoteProxy` read. A unit test covers the nil receiver, nil `Inline` subtree, inline without the field, and inline with the field set. * `MCPServer.validateAuthzPrimaryUpstreamProviderIgnored` and the equivalent on `MCPRemoteProxy` set the `AuthzPrimaryUpstreamProviderIgnored` advisory condition when the deprecated field is set on a CR that has no embedded auth server to act on it. Both functions existed before this PR but had no test coverage at all. The relocation of the field did not change their behaviour, but the absence of coverage means a regression there would go unnoticed. Add table-driven tests that exercise the True-on-set, absent-when-unset, and stale-cleared cases. * `VirtualMCPServerReconciler.validateAuthzUpstreamAvailable` emits a `Warning` event with reason `AuthzPrimaryUpstreamProviderDeprecated` whenever it resolves the primary from the deprecated location, so operators see a kubectl-visible signal even when the deprecated value still validates. A test using `events.NewFakeRecorder` confirms the event fires for the deprecated path, does not fire for the canonical path, and does not fire when neither location is set. No production code changes; only tests. * Wire claim-mapping fields on the runner path The previous commit lifted `GroupClaimName`, `RoleClaimName`, and `GroupEntityType` onto `AuthzConfigRef` with a docstring promising spec -over-ConfigMap override semantics for inline and configMap-sourced authz alike. The vMCP converter threaded the fields into the rendered `config.yaml`, but the runner path used by `MCPServer` and `MCPRemoteProxy` (`addAuthzInlineConfigOptions` plus the configMap branch of `AddAuthzConfigOptions`) passed `*authz.Config` straight to `runner.WithAuthzConfig` and dropped the new fields on the floor. Setting them on those CRDs was a silent no-op, in violation of the field documentation and the "no silent no-ops" rule in `.claude/rules/go-style.md`. Apply the override on both runner-path branches: * `addAuthzInlineConfigOptions` now reads the three fields directly from the parent `AuthzConfigRef` and bakes them into `cedar.ConfigOptions`. Extracted as `BuildInlineCedarAuthzConfig` so tests can inspect the resulting `*authz.Config` without going through the runner builder. * The configMap branch of `AddAuthzConfigOptions` calls a new `ApplyClaimMappingOverrides` helper after `LoadAuthzConfigFromConfigMap`. The helper unwraps the Cedar options, applies non-empty spec-level fields field-by-field (so an empty spec field preserves the ConfigMap value, no accidental clobbering), and re-wraps. Non-Cedar configs pass through unchanged. * Introduced `ExtractCedarAuthzOptions` as the shared unwrap primitive. The vMCP converter now uses this helper and drops its direct dependency on `pkg/authz/authorizers/cedar`, keeping the Cedar specifics localised to `controllerutil`. Tests in `authz_test.go` lock the three-field threading on `BuildInlineCedarAuthzConfig`, the field-by-field precedence on `ApplyClaimMappingOverrides` (nil ref, no-op ref, single-field override, mixed override with ConfigMap fallback), the nil-cfg defense, and the unwrap helper happy/error paths. Addresses F1 from the multi-agent consensus review on PR #5290 and the sibling `converter.go:224` layering nit. * Tighten authz validation from review feedback Three discrete fixes from the multi-agent review on PR #5290, all focused on closing silent-failure windows in the authz path. F9: `convertAuthzConfig` now has a `default:` arm rejecting unknown `authzRef.Type` values. The CRD enum blocks unknown values at admission, but the converter is also reachable from CLI dry-runs, webhooks, and test harnesses where a stale schema could let a future authz source through. Falling through with empty `Policies` produced a Cedar config that silently denied every request. The stale "configMap → cedar once we populate policies" comment is dropped at the same time. F11: `validateAuthzConfigMapRef` now runs `ExtractCedarAuthzOptions` on the loaded payload. A configMap that parses as a valid `authz.Config` but isn't Cedar-flavoured (e.g. the registered `httpv1` HTTP authorizer) previously passed pre-validation, set `AuthConfigured=True`, and then failed opaquely at convert time. The pre-validator and the converter now agree on what "valid" means. F15: `validateAuthzUpstreamAvailable` emits the `AuthzPrimaryUpstreamProviderDeprecated` Warning event in the no-auth-server reject branch too, not only on the validated-AS path. The mid-migration user (deprecated inline field set, `authServerConfig` not yet configured) gets the hard reject AND the deprecation hint, not just the reject. Extracted as `emitPrimaryUpstreamProviderDeprecatedEvent` so both validation branches stay in sync. Tests: * `TestConvertAuthzConfig_UnknownTypeIsRejected` covers the new default arm. * `TestValidateAuthzConfigMapRef` grows a "valid authz.Config but non-Cedar type is rejected" case using the registered `httpv1` payload shape. * `TestVirtualMCPServerValidateAuthzUpstreamAvailable_DeprecationEvent` grows a "no-auth-server branch emits the event before reject" case that exercises the event + error path together. * Soften `PrimaryUpstreamProvider` docs for non-vMCP CRDs Tightens the docstrings on the two locations of `PrimaryUpstreamProvider` to match the actual code paths and addresses F4 (and the cascading F5) from the multi-agent review on PR #5290. `EmbeddedAuthServerConfig.PrimaryUpstreamProvider`: previously claimed that the field was validated against `UpstreamProviders` on MCPServer and MCPRemoteProxy as well. No code references the field on those paths: the proxyrunner pipeline does not read it, and the existing `AuthzPrimaryUpstreamProviderIgnored` advisory inspects only the legacy inline location. The new docstring says the field is meaningful only on `VirtualMCPServer`; on single-upstream consumers it is structurally present (the struct is shared) but silently ignored. `InlineAuthzConfig.PrimaryUpstreamProvider` (deprecated): the previous deprecation block named both `spec.authServerConfig.primaryUpstreamProvider` (canonical on vMCP) and `embeddedAuthServer.primaryUpstreamProvider` on a referenced `MCPExternalAuthConfig` as canonical replacements, then immediately said the field is structurally meaningless on MCPServer/MCPRemoteProxy. Two sentences pointing in opposite directions. The new block names only the vMCP canonical location and makes explicit that on MCPServer/MCPRemoteProxy the deprecated form was always a structural no-op and the deprecation does not change that behaviour. No code changes. Regenerated `deepcopy`, CRD YAML, and CRD reference docs to pick up the docstring updates. * Sync `primaryUpstreamProvider` guidance in user-facing docs Two user-facing docs and one in-code constant comment had drifted relative to the schema and runtime behaviour shipped earlier on this branch. The schema docstrings and CRD reference were already in sync with the code; this commit catches up the prose that users actually read first. * `docs/operator/virtualmcpserver-api.md`: the `authzConfig` section listed `primaryUpstreamProvider` under `inline` with no deprecation note, did not mention the new top-level claim-mapping fields on `AuthzConfigRef`, and did not document the failure modes on `AuthConfigured`. The new prose marks the inline location as deprecated, points to `spec.authServerConfig.primaryUpstreamProvider`, describes `groupClaimName` / `roleClaimName` / `groupEntityType` with their spec-over-ConfigMap precedence, and names the `AuthzConfigMapNotFound` / `AuthzConfigMapInvalid` reasons users will see on misconfiguration. Addresses F2. * `docs/operator/virtualmcpserver-kubernetes-guide.md`: the "Multiple upstream IDPs" troubleshooting block pinned `primaryUpstreamProvider` at the deprecated inline location, so anyone following the guide would emit `AuthzPrimaryUpstreamProviderDeprecated` events on every reconcile. The example now uses `spec.authServerConfig.primaryUpstreamProvider`. Adds a "Migration: `primaryUpstreamProvider` location" note that names the deprecation event reason and the planned removal cadence. Adds an "Authorization policy errors" subsection covering `AuthzConfigMapNotFound` / `AuthzConfigMapInvalid` and an "Enterprise Cedar policies that deny every request" subsection covering the claim-mapping knobs. Addresses F3, F7, and F13. * `cmd/thv-operator/api/v1beta1/mcpserver_types.go`: `ConditionTypeAuthzPrimaryUpstreamProviderIgnored` now carries the deprecation lineage in its doc comment. The condition fires only for the deprecated `InlineAuthzConfig.PrimaryUpstreamProvider` field; when that field is removed at end of the deprecation cycle, this condition and its reason constant should be removed in the same change. Addresses Jakub's PR-level nit. No code changes; comment and prose only. --- .../v1beta1/mcpexternalauthconfig_types.go | 20 + .../api/v1beta1/mcpserver_types.go | 87 +++- .../api/v1beta1/virtualmcpserver_types.go | 29 ++ .../v1beta1/virtualmcpserver_types_test.go | 129 ++++++ .../controllers/mcpremoteproxy_controller.go | 2 +- .../mcpremoteproxy_reconciler_test.go | 100 +++++ .../controllers/mcpserver_authz_test.go | 102 +++++ .../controllers/mcpserver_controller.go | 2 +- .../virtualmcpserver_authz_validation_test.go | 237 +++++++++++ .../virtualmcpserver_controller.go | 89 ++++- .../virtualmcpserver_controller_test.go | 170 +++++++- .../virtualmcpserver_deployment.go | 34 ++ cmd/thv-operator/pkg/controllerutil/authz.go | 223 ++++++++--- .../pkg/controllerutil/authz_test.go | 249 ++++++++++++ cmd/thv-operator/pkg/vmcpconfig/converter.go | 191 ++++++--- .../converter_authz_configmap_test.go | 370 ++++++++++++++++++ .../pkg/vmcpconfig/converter_test.go | 87 +++- ...e.stacklok.dev_mcpexternalauthconfigs.yaml | 40 ++ ...oolhive.stacklok.dev_mcpremoteproxies.yaml | 124 ++++-- .../toolhive.stacklok.dev_mcpservers.yaml | 124 ++++-- ...olhive.stacklok.dev_virtualmcpservers.yaml | 224 +++++++++-- ...e.stacklok.dev_mcpexternalauthconfigs.yaml | 40 ++ ...oolhive.stacklok.dev_mcpremoteproxies.yaml | 124 ++++-- .../toolhive.stacklok.dev_mcpservers.yaml | 124 ++++-- ...olhive.stacklok.dev_virtualmcpservers.yaml | 224 +++++++++-- docs/operator/crd-api.md | 18 +- docs/operator/virtualmcpserver-api.md | 34 +- .../virtualmcpserver-kubernetes-guide.md | 63 ++- pkg/vmcp/auth/factory/incoming.go | 15 +- pkg/vmcp/config/config.go | 30 ++ 30 files changed, 2941 insertions(+), 364 deletions(-) create mode 100644 cmd/thv-operator/controllers/virtualmcpserver_authz_validation_test.go create mode 100644 cmd/thv-operator/pkg/vmcpconfig/converter_authz_configmap_test.go diff --git a/cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go b/cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go index 0aefd93764..467b445924 100644 --- a/cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go +++ b/cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go @@ -232,6 +232,26 @@ type EmbeddedAuthServerConfig struct { // +listMapKey=name UpstreamProviders []UpstreamProviderConfig `json:"upstreamProviders"` + // PrimaryUpstreamProvider names the upstream IDP whose access token Cedar + // should read claims from when authorising a request.

scopes into the registered set returned by RFC 7591 Dynamic Client
Registration, so a client that narrows the `scope` field at /oauth/register
can still request the baseline scopes at /oauth/authorize. All values must
be present in the upstream-derived scopesSupported set; the auth server
fails to start if any value is missing.
Security: every client registered via /oauth/register will gain the
ability to request these scopes at /oauth/authorize, regardless of what
the client itself requested. Keep the baseline narrow (typically
"openid" and "offline_access"). Adding a privileged scope here — e.g.
"admin:read" — would grant it to every DCR-registered client, including
public clients like Claude Code, Cursor, and VS Code. | | MaxItems: 10

Before this change, an obo-typed MCPExternalAuthConfig surfaced Valid=False/EnterpriseRequired only on the referenced resource. The consumer CR (MCPServer, MCPRemoteProxy, VirtualMCPServer) showed only the generic dispatch failure, leaving users to inspect the referenced config to understand why their workload would not deploy. Each consumer reconciler now inspects the referenced config's Valid condition. When it is False, the reconciler mirrors the source's reason and message onto its own ExternalAuthConfigValidated condition (or per-backend DiscoveredAuthConfig/BackendAuthConfig condition for vMCP). This must merge before #5329 lights up apiserver-level admission of obo-typed configs so production users see the failure on the resource they applied. The envtest integration test for this propagation is deferred to #5329 to avoid adding a setup-envtest dependency here; once #5329 admits "obo" at the CRD layer, the test no longer needs a CRD-enum bypass. Co-Authored-By: Claude Opus 4.7 (1M context) * Address code review feedback on consumer-CR mirror Two changes from the code review on the previous commit: 1. (correctness) MCPServer.handleExternalAuthConfig now clears any stale ExternalAuthConfigValidated=False the mirror previously wrote when the referenced source has healed (Valid=True or absent). Without this, the False condition outlived its cause: the user fixed their spec but the mirror stayed sticky because MCPServer has no downstream True setter on this condition. Adds a regression-guard test case. 2. (parity) The mirror probe, typed error, and reason-extraction helper now live in a shared external_auth_mirror.go file instead of being duplicated across the three consumer reconcilers. All three reconcilers (MCPServer, MCPRemoteProxy, VirtualMCPServer) call the same primitive and surface the same typed error so downstream consumers like buildOutgoingAuthConfig can react without string-matching. MCPRemoteProxy already sets ExternalAuthConfigValidated=True downstream and so does not need the heal-clearing branch — its existing True writer overwrites any stale mirror. VirtualMCPServer heals naturally because setAuthConfigConditions removes stale per-backend conditions on each reconcile. Co-Authored-By: Claude Opus 4.7 (1M context) * Tighten mirror probe API; trim duplicated error prefix Two changes from the second round of code review feedback on the consumer-CR mirror: 1. mirroredExternalAuthConfigInvalid now returns the typed *mirroredInvalidExternalAuthConfigError directly (nil when the source is healed) instead of a (reason, error) tuple. Callers no longer need errors.As to recover the message field, and the pointer-or-nil shape removes the awkward "discard the bool" pattern at the MCPServer and MCPRemoteProxy call sites. The typed value still satisfies the error interface so vMCP's convertBackendAuthConfigToVMCP can keep passing it through opaque error-returning APIs and recover the reason later via mirroredReasonFromError. 2. MCPServer and MCPRemoteProxy's outer error wrap no longer repeats the typed error's "referenced MCPExternalAuthConfig is invalid" prefix, so messages render as a single sentence instead of a doubled phrase. The namespaced name is preserved through %w. Updates the mirror probe's unit test to the new return shape and adds a round-trip assertion that the typed pointer flows through mirroredReasonFromError. Co-Authored-By: Claude Opus 4.7 (1M context) * Clear stale consumer-CR mirror across all heal paths Addresses stacklok/toolhive#5354 review comments: - HIGH cmd/thv-operator/controllers/mcpserver_controller.go (F1): the previous mirror added in this branch handled the source-Valid-flips-True heal path, but the no-ref early-return in handleExternalAuthConfig never reached the helper, so removing the spec.externalAuthConfigRef left a stale Valid=False/EnterpriseRequired on the consumer indefinitely. Clear the condition in the no-ref branch and in both NotFound branches so the mirror does not outlive its cause. - MEDIUM cmd/thv-operator/controllers/mcpremoteproxy_controller.go (F2): mirror helper now defensively clears its own condition on the healed path, matching MCPServer. The downstream True-writer at the end of handleExternalAuthConfig still sets the ConditionReasonMCPRemoteProxyExternalAuthConfigValid reason on success; the defensive clear closes the gap if a future control-flow change adds an early return between this helper and that writer. - LOW cmd/thv-operator/controllers/mcpserver_externalauth_test.go (F10): two new regression-guard tests for the heal paths uncovered by F1 — spec.externalAuthConfigRef removed, referenced source NotFound. Co-Authored-By: Claude Opus 4.7 (1M context) * Consolidate mirror helpers; tighten error+test contract Addresses stacklok/toolhive#5354 review comments: - MEDIUM cmd/thv-operator/controllers/virtualmcpserver_externalauth_test.go (F3): add a wrapped-error round-trip assertion so a future %w -> %v regression in buildOutgoingAuthConfig can't silently break per-backend reason propagation. - MEDIUM cmd/thv-operator/controllers/mcpserver_controller.go (F4): move both consumer mirror functions to free functions in external_auth_mirror.go (mirrorInvalidOnMCPServer / mirrorInvalidOnRemoteProxy) instead of one method with an unused receiver and one suffixed free function. Single canonical home. - LOW cmd/thv-operator/controllers/mcpserver_controller.go (F5): drop the "referenced MCPExternalAuthConfig is invalid" prefix from the typed error's Error(); the outer wrap on each consumer carries the namespaced name. Rendered messages now read "MCPExternalAuthConfig ns/name: invalid (Reason): Message". - LOW cmd/thv-operator/controllers/external_auth_mirror.go (F6): substitute a fallback reason when the source surfaces Valid=False with an empty Reason so the apiserver patch cannot fail validation on a corrupt/partial source status. Add a TestMirroredExternalAuthConfigInvalid subtest for the empty-Reason input. - LOW cmd/thv-operator/controllers/external_auth_mirror.go (F7): trim the probe doc; package-level comment carries the #5347 motivation once, the per-function docs are now contract-only. - LOW cmd/thv-operator/controllers/mcpremoteproxy_controller_test.go (F8): add expectedCondMessage to the test table and assert it on the OBO mirror row. - LOW cmd/thv-operator/controllers/mcpserver_externalauth_test.go (F9): set non-zero Generation on the test fixtures and assert ObservedGeneration on the mirrored condition. Same gap covered on the MCPRemoteProxy row.

Implements changes for issue #5329: - Extend the CRD enum, CEL rules, and Go-level validateTypeConfigConsistency check on MCPExternalAuthConfigSpec to admit and validate the new "obo" type alongside the existing seven - Declare an opaque OBOConfig placeholder struct and spec.obo field; the inner schema lands in a follow-up - Document the two-tier validation pattern on the Validate() OBO arm: structural validation here, semantic validation behind the controllerutil.OBOValidate function-pointer hook at reconcile time - Regenerate operator-crds chart YAML, deepcopy, and public CRD reference - Add unit tests covering the OBO validation matrix and update existing OBO-typed test fixtures across operator and vMCP packages * Justify gocyclo suppression and document unauthenticated guard intent Address code-review feedback on the CRD admission change: - Expand the doc comment on validateTypeConfigConsistency so the //nolint:gocyclo directive meets the "confirmed false positive" bar from .claude/rules/go-style.md. The per-type if shape mirrors the CEL rules on MCPExternalAuthConfigSpec one-to-one; collapsing into a table-driven loop would obscure that correspondence. - Add an explanatory comment on the unauthenticated guard so it reads as shape-parity / belt-and-braces, not load-bearing validation. The per-type biconditionals above always intercept a populated config field first; the guard exists so a future contributor adding a type cannot forget to extend the invariant. * Polish OBO admission comments and test names Addresses stacklok/toolhive#5361 review comments: - LOW types.go (3283528614): F1 — say unauthenticated-guard OBO disjunct is unreachable; retained for forward-compat - LOW types.go (3283528635): F2 — replace stale "lines 44-49" ref in Validate() doc with structural reference - LOW types.go (3283528640): F3 — concrete OBOConfig rationale (compiles, admits spec.obo: {}); drop speculative downstream-consumer phrasing - LOW types.go (3283528649): F4 — note structural validation already ran in OBO Validate() arm comment - LOW types_test.go (3283528655): F5 — rename test #4 to note OBO biconditional intercepts first - LOW types_test.go (3283528662): F6 — move OBO test cases next to upstreamInject group - LOW types.go (3283528670): F7 — copy nolint:gocyclo rationale onto the directive line - LOW types.go (3283528675): F8 — extend Type field doc with obo build-requires-handler note (regenerated YAML + crd-api.md) - INFO types_test.go (3283528682): F9 — rename "empty config" to "placeholder OBOConfig" --- .../v1beta1/mcpexternalauthconfig_types.go | 81 ++++++++++++++----- .../mcpexternalauthconfig_types_test.go | 63 +++++++++++++++ .../api/v1beta1/zz_generated.deepcopy.go | 20 +++++ .../mcpexternalauthconfig_controller_test.go | 3 + .../mcpremoteproxy_controller_test.go | 1 + .../mcpserver_externalauth_test.go | 1 + .../virtualmcpserver_externalauth_test.go | 2 + .../pkg/controllerutil/tokenexchange_test.go | 1 + ...e.stacklok.dev_mcpexternalauthconfigs.yaml | 42 +++++++++- ...e.stacklok.dev_mcpexternalauthconfigs.yaml | 42 +++++++++- docs/operator/crd-api.md | 22 ++++- pkg/vmcp/auth/converters/obo_test.go | 3 + 12 files changed, 253 insertions(+), 28 deletions(-) diff --git a/cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go b/cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go index 467b445924..25bd4f603f 100644 --- a/cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go +++ b/cmd/thv-operator/api/v1beta1/mcpexternalauthconfig_types.go @@ -61,12 +61,17 @@ type ExternalAuthType string // +kubebuilder:validation:XValidation:rule="self.type == 'embeddedAuthServer' ? has(self.embeddedAuthServer) : !has(self.embeddedAuthServer)",message="embeddedAuthServer configuration must be set if and only if type is 'embeddedAuthServer'" // +kubebuilder:validation:XValidation:rule="self.type == 'awsSts' ? has(self.awsSts) : !has(self.awsSts)",message="awsSts configuration must be set if and only if type is 'awsSts'" // +kubebuilder:validation:XValidation:rule="self.type == 'upstreamInject' ? has(self.upstreamInject) : !has(self.upstreamInject)",message="upstreamInject configuration must be set if and only if type is 'upstreamInject'" -// +kubebuilder:validation:XValidation:rule="self.type == 'unauthenticated' ?

When the embedded AS receives a client_id like https://vscode.dev/oauth/client-metadata.json, the decorator fetches the CIMD document via pkg/oauthproto/cimd, validates it, builds a fosite.Client, caches the result with a configurable fallback TTL, and deduplicates concurrent fetches for the same URL via singleflight. Key design decisions: - Embeds storage.Storage so all ~30 other methods delegate transparently - Unwrap() exposes the underlying storage for the DCRCredentialStore and RedisStorage type assertions in server_impl.go to reach the concrete backend through the decorator layer - LoopbackClient wraps clients with loopback redirect URIs for RFC 8252 §7.3 dynamic port matching - NewCIMDStorageDecorator returns base unchanged when enabled=false (no allocation); fails loudly for invalid cacheMaxSize runLegacyMigration extracted from newServer to keep the function under the gocyclo limit after the Unwrap additions; both the DCRCredentialStore assertion and the RedisStorage migration now use the same Unwrap pattern. Incorporates all changes from PR 1 (pkg/oauthproto/cimd sub-package, networking.FetchJSON with WithMaxResponseSize, IsPrivateIP reuse). Relates to #4825 Co-Authored-By: Claude Sonnet 4.6 (1M context) * Address Copilot review comments on CIMD storage decorator cimd_decorator.go: - Fix docstring: TTL is fixed (not from Cache-Control); Cache-Control parsing is a documented follow-up - Force token_endpoint_auth_method to "none": the embedded AS only advertises "none" in discovery, so accepting other values creates an inconsistent client; always override regardless of what the document says - Fix LoopbackClient dropping TokenEndpointAuthMethod: was passing defaultClient (no auth method) instead of openIDClient.DefaultClient (carries the auth method) to NewLoopbackClient - Fix singleflight context: use context.WithoutCancel(ctx) so one caller cancelling does not abort the shared in-flight fetch for other waiters; HTTP client inside FetchClientMetadataDocument already enforces its own 5-second timeout cimd_decorator_test.go: - Replace flaky time.Sleep with a startBarrier channel: goroutines signal before calling fetchOrCached; draining all signals before closing ready makes singleflight deduplication deterministic - Fix CIDM → CIMD typo in test name server_impl.go: - Fix error message: report baseStore type (concrete backend) not stor type (possibly a decorator) when DCRCredentialStore assertion fails - Extract unwrapStorage helper to deduplicate the identical Unwrap() inline logic in newServer and runLegacyMigration Co-Authored-By: Claude Sonnet 4.6 (1M context) * Address agent review feedback on CIMD storage decorator Issue 1 (blocking): actually fix LoopbackClient dropping TokenEndpointAuthMethod. Change LoopbackClient to embed *fosite.DefaultOpenIDConnectClient instead of *fosite.DefaultClient, preserving TokenEndpointAuthMethod through the wrapper. Update NewLoopbackClient signature, registration.New(), buildFositeClient, and all test call sites accordingly. Previous "fix" was wrong: openIDClient.DefaultClient is the same pointer as defaultClient — the behaviour was identical to the original broken code. Issue 2: remove dead `enabled bool` field from CIMDStorageDecorator. The constructor returns base unchanged when enabled=false so the struct is never instantiated with enabled=false; the field was never read. Issue 3: add TestCIMDStorageDecorator_FetchOrCached_FetchFailureReturnsNotFound covering the error path and verifying errors.Is(err, fosite.ErrNotFound). Issue 4: add CIMD decorator section to docs/arch/11-auth-server-storage.md covering what the decorator does, the Unwrap() pattern, and the air-gapped caveat. Issue 5: replace //nolint:forcetypeassert with a safe type assertion that returns an observable error instead of panicking on type mismatch. Co-Authored-By: Claude Sonnet 4.6 (1M context) * Fix two remaining nits - server_impl.go: remove stray blank comment line - cimd_decorator_test.go: add TokenEndpointAuthMethod assertion to LoopbackClient test to catch any future regression Co-Authored-By: Claude Sonnet 4.6 (1M context) * Reject CIMD docs that declare unsupported token_endpoint_auth_method The embedded AS only supports "none" for CIMD clients. Previously, buildFositeClient silently overrode any declared auth method to "none", which was misleading: a client that claimed private_key_jwt would be treated as public without any indication of the mismatch. Now fetch() rejects documents that declare a method other than "none" before buildFositeClient is reached. buildFositeClient only fills in "none" as a default when the field is omitted, which matches the comment on defaultCIMDTokenEndpointAuthMethod.

<328978+blkt@users.noreply.github.com> Date: Tue, 26 May 2026 12:15:56 +0200 Subject: [PATCH 216/291] Address post-approval review feedback on `VirtualMCPServer` authz (#5368) Follow-ups from the post-approval review of #5290, bundled because they touch overlapping files: * Distinguish `AuthzConfigMapInvalid` from `AuthzConfigMapNotFound` on `MCPRemoteProxy`, restoring status condition parity with `VirtualMCPServer`. * Gate the `AuthzPrimaryUpstreamProviderDeprecated` warning event on a generation transition so it fires once per spec change. * Align the authz config `version` field on `"1.0"` via a shared constant; the inline path previously diverged with `"v1"`. * Narrow the misleading `ExtractCedarAuthzOptions` doc comment. --- .../api/v1beta1/mcpremoteproxy_types.go | 10 +++-

The shared OAuthTokenSource also persists an access-token cache under "_AT", and its tier-2 lookup reads that key directly. The cached access token survived logout, so the next thv registry login short-circuited through the cache instead of triggering a fresh browser flow. Replace the targeted deletes with a list-and-bulk-delete over every secret visible to the registry-scoped provider, mirroring pkg/llm.DeleteCachedTokens.

charset=UTF-8 Content-Transfer-Encoding: 8bit * Wire CIMD config through embedded AS and enable storage decorator Phase 2 PR 3 — config threading and server wiring. Config chain: RunConfig.CIMD → Config.CIMD* → AuthorizationServerParams → AuthorizationServerConfig → discovery handler. Changes: - config.go: add CIMDRunConfig struct and CIMD* fields to Config; defaults (256 entries, 5 min fallback TTL) applied in applyDefaults(); validation (cacheMaxSize >= 1 when enabled) in Validate() - runner/embeddedauthserver.go: add resolveCIMDConfig helper to unpack nullable *CIMDRunConfig; populate Config.CIMD* from RunConfig.CIMD - server/provider.go: add CIMDEnabled to AuthorizationServerParams and AuthorizationServerConfig; wire through NewAuthorizationServerConfig - server_impl.go: wrap storage with CIMDStorageDecorator when enabled (after legacy migration, before createProvider — decorator must be in place before fosite holds a reference to the storage instance); pass CIMDEnabled to AuthorizationServerParams - server/handlers/discovery.go: set ClientIDMetadataDocumentSupported in buildOAuthMetadata() — both OAuth AS and OIDC discovery endpoints advertise CIMD support when enabled CIMD is opt-in (disabled by default) to avoid introducing outbound HTTPS fetching in existing deployments without explicit operator action. Relates to #4825 Co-Authored-By: Claude Sonnet 4.6 (1M context) * Address PR review feedback on CIMD wiring and add missing tests - Fix CacheFallbackTTL comment to say it is a fixed TTL (not fallback); matches the fix already applied in PR #5343 - Add TODO(cimd) comment above CIMDRunConfig noting the CRD exposure gap - Add discovery handler tests: CIMDEnabled=true advertises the flag, CIMDEnabled=false omits it, for both AS metadata and OIDC endpoints - Add config defaults tests: CIMDEnabled=true fills in cache size/TTL defaults; CIMDEnabled=false leaves zero fields unchanged - Add resolveCIMDConfig nil-guard test: nil input returns zero values, non-nil passes all fields through Co-Authored-By: Claude Sonnet 4.6 (1M context) * Extend IsClientIDMetadataDocumentURL to accept http://localhost URLs The embedded AS must resolve CIMD client_ids for local development and testing the same way FetchClientMetadataDocument does — accepting http://localhost and http://127.x.x.x in addition to https://. This brings IsClientIDMetadataDocumentURL in line with validateCIMDClientURL in pkg/oauthproto/cimd/fetch.go which already permits these schemes. Co-Authored-By: Claude Sonnet 4.6 (1M context) * Regenerate swagger docs to include CIMDRunConfig Run task docs to pick up the new CIMDRunConfig struct added in this PR. Co-Authored-By: Claude Sonnet 4.6 (1M context) * Default to registration.DefaultScopes when CIMD doc omits scope field When a CIMD document does not include a scope field, buildFositeClient was producing a client with no allowed scopes. Any authorization request specifying openid, profile, or offline_access would then fail with "scope not allowed". DCR registration applies DefaultScopes in the same situation, so CIMD clients should behave identically. Found during manual testing with VS Code as a CIMD client. Co-Authored-By: Claude Sonnet 4.6 (1M context) * Trigger CI re-run * Address PR review feedback on CIMD wiring - Fix IsClientIDMetadataDocumentURL comment: accepted loopbacks are localhost/127.0.0.1/[::1], not the full 127.x.x.x range - Fix hostFromURL doc: returns host+port, not host without port - Add loopback and subdomain-bypass test cases to TestIsClientIDMetadataDocumentURL (Claude blocking issue) - Fix Config.CIMDCacheFallbackTTL comment: Cache-Control is not parsed - Add validation: CIMDCacheFallbackTTL must be non-negative when enabled - Clone registration.DefaultScopes in buildFositeClient to prevent aliasing the package-level slice - Fix CIMDDisabled discovery test to decode to map[string]interface{} so it verifies the field is truly absent (omitempty) not just false The DefaultScopes change in cimd_decorator.go was introduced here (rather than in PR #5343) because the gap was discovered during manual testing of the wiring: VS Code's CIMD document omits scope and the nil scopes caused an auth failure. Co-Authored-By: Claude Sonnet 4.6 (1M context) * Use net/url to extract host in IsClientIDMetadataDocumentURL net/url is already imported by four other files in pkg/oauthproto, so the previous comment about keeping the package "import-free" was incorrect. url.Parse handles IPv6 brackets and other edge cases correctly without manual string manipulation. Co-Authored-By: Claude Sonnet 4.6 (1M context) * Address tgrunnagle feedback on CIMD wiring C1 - Fix CacheFallbackTTL to string in CIMDRunConfig so YAML/JSON operators can write "5m" instead of nanoseconds. resolveCIMDConfig parses it with time.ParseDuration at runtime. C6 - Add slog.Debug when applyDefaults substitutes CIMD defaults, matching the pattern used by the sibling token-lifespan defaults. C7 - Add CIMDRunConfig.Validate() and call it from RunConfig.Validate() so CIMD misconfiguration fails at the wire-format boundary before the runner resolves secrets. C10 - Add test cases to TestConfigValidate and TestRunConfigValidate covering all new CIMD validation paths. C11 - Add TestNewServer_CIMDEnabled_WrapsStorage: verifies the CIMD decorator is actually installed in the storage chain when CIMDEnabled=true. C12 - Add comment in discovery.go explaining why client_id_metadata_document_supported is in OIDC discovery. C13 - Add doc comment on server.storage noting it may be decorated. C14 - Add note to IsClientIDMetadataDocumentURL about pkg/auth/remote callers and why the loopback widening is safe there. Regenerate swagger docs: CacheFallbackTTL now serialises as string.

This refresh cross-references every claim against the current code in both repos and brings the docs back in sync. Highlights: - Repoint moved packages: pkg/permissions, pkg/registry/types, pkg/registry/data/registry.json, secrets/aes key derivation, runtime monitor, and the registry-api manager - Expand the operator CRD inventory: add EmbeddingServer (Auxiliary, StatefulSet) and MCPWebhookConfig; rename ToolConfig -> MCPToolConfig - Fix CRD field paths: spec.config.compositeToolRefs; spec.incomingAuth.oidcConfigRef on VirtualMCPServer; MCPGroupRef consumers expanded to all four CRDs - Rewrite vMCP middleware order to match server.go wrap order; correct Reporter interface naming; note logging reporter is Debug-level - Add Cluster mode to the auth-server storage doc; flatten the timeouts CRD shape; fix sentinelTls casing; surface DCRCredentialStore - Replace stale registry pieces: built-in catalog source, legacy top-level JSON examples, registry-API endpoint paths (/v0.1/servers, /v0.1/servers/:name/versions/latest), deprecation of thv group run - Expand transport docs: NamedMiddleware constructor type; MCP env vars emitted only by pkg/runtime/setup.go; 127.0.0.1 default lives in the config builder; SSE rewrite in sse_response_processor.go - Complete middleware enumeration in 02 and 05 (upstreamswap, awssts, obo, ratelimit, usagemetrics, recovery, header-forward, validating- webhook, mutating-webhook); fix authz -> authorization constant - Restore pkg/secrets/types.go reference (EnvVarPrefix + Provider interface); point pod builder at pkg/controllerutil - Skills: replace nonexistent skillsvc.go with real file inventory; add GET /content endpoint; mark oci_tags as reserved; correct OCI artifact name-match (last path component) - Smaller fixes: OrbStack across runtime lists; runtime detection order Podman -> Docker -> Colima; drop bogus TOOLHIVE_DETACHED env var and SENTRY_TRACES_SAMPLE_RATE env-var fallback; add unknown and policy_stopped lifecycle states; add inspector transport - Preserve correct StatefulSet wording throughout (proxy-runner is a Deployment; the MCP server pod is a StatefulSet created via pkg/container/kubernetes/client.go applyStatefulSet) Co-authored-by: Claude Opus 4.7 (1M context) --- docs/arch/00-overview.md | 4 +- docs/arch/01-deployment-modes.md | 38 ++--- docs/arch/02-core-concepts.md | 42 ++++-- docs/arch/03-transport-architecture.md | 18 ++- docs/arch/04-secrets-management.md | 10 +- docs/arch/05-runconfig-and-permissions.md | 67 +++++---- docs/arch/06-registry-system.md | 47 +++--- docs/arch/07-groups.md | 2 +- docs/arch/08-workloads-lifecycle.md | 5 +- docs/arch/09-operator-architecture.md | 166 ++++++++++++---------- docs/arch/10-virtual-mcp-architecture.md | 31 ++-- docs/arch/11-auth-server-storage.md | 43 +++--- docs/arch/12-skills-system.md | 23 +-- docs/arch/13-vmcp-scalability.md | 29 ++-- docs/arch/vmcp-library.md | 1 + 15 files changed, 299 insertions(+), 227 deletions(-) diff --git a/docs/arch/00-overview.md b/docs/arch/00-overview.md index f4341ed3b2..1e547883d0 100644 --- a/docs/arch/00-overview.md +++ b/docs/arch/00-overview.md @@ -87,7 +87,7 @@ thv run go://package-name Manages MCP servers in Kubernetes clusters using custom resources. -The operator watches for `MCPServer`, `MCPRegistry`, `MCPToolConfig`, `MCPExternalAuthConfig`, `MCPGroup`, and `VirtualMCPServer` CRDs, reconciling them into Kubernetes resources (Deployments, StatefulSets, Services). +The operator watches a layered set of CRDs (Core: `MCPServer`, `MCPRemoteProxy`, `MCPServerEntry`; Organization: `MCPGroup`; Aggregation: `VirtualMCPServer`, `VirtualMCPCompositeToolDefinition`; Discovery: `MCPRegistry`; Configuration: `MCPToolConfig`, `MCPExternalAuthConfig`, `MCPOIDCConfig`, `MCPTelemetryConfig`, `MCPWebhookConfig`; Auxiliary: `EmbeddingServer`) and reconciles them into Kubernetes resources (proxy-runner Deployments and Services; ConfigMaps; the MCP server itself is created as a StatefulSet by the proxy-runner, while `EmbeddingServer`'s StatefulSet is created by the operator directly).

TDD test in cmd/thv-proxyrunner/app/run_test.go for the env-var override (THV_MCPSERVER_GENERATION) that the fix in #5360 will introduce. Fails today; goes green when the override is implemented. Co-Authored-By: Claude Opus 4.7 (1M context) * Freeze proxyrunner MCPServerGeneration via env var The /etc/runconfig ConfigMap volume mounts live (no subPath), so a restarted old-RS proxyrunner pod re-reads runconfig.json after a helm upgrade and picks up the new MCPServer generation. Both old and new pods then call DeployWorkload with the same ourGen, defeating the strict-greater-than gate at shouldSkipStatefulSetApply. Honor THV_MCPSERVER_GENERATION (sourced via downward API in a follow-up operator change) as an override on the file value, freezing the generation per pod at creation time. Parallel to how the image is already frozen via the CLI positional arg. Part of #5360. Co-Authored-By: Claude Opus 4.7 (1M context) * Project MCPServer generation into proxyrunner via downward API Stamp the MCPServer generation as a pod-template annotation on the proxy Deployment, and project that annotation into the proxyrunner container as the THV_MCPSERVER_GENERATION env var via the downward API. The env var is bound to the pod's own annotations at creation time, so a restarted old-RS pod cannot acquire the new generation by re-reading the live-mounted RunConfig ConfigMap. The proxyrunner already honors this env var as an override on the file value (see prior commit). With both sides wired, two coexisting proxyrunner pods during a rolling update carry distinct generations again and the strict-greater-than gate at shouldSkipStatefulSetApply fires correctly. Mirror the new env var and annotation in deploymentNeedsUpdate so drift detection stays stable. Closes #5360. Co-Authored-By: Claude Opus 4.7 (1M context) * Add envtest coverage for generation-freeze contract Two new integration specs assert the operator side of the freeze end-to-end against a real apiserver: - On initial reconcile, the proxy Deployment's pod template carries the mcpserver-generation annotation set to MCPServer.metadata.generation, and the proxyrunner container declares THV_MCPSERVER_GENERATION via a downward-API FieldRef pointing at that exact annotation key. - On a Spec.Image patch the controller bumps the annotation value to the new generation and keeps the FieldRef wired correctly. This is the rolling-update path: new pods get a strictly-greater frozen generation than any restarted old-RS pod. Catches typos in either the annotation key or the FieldRef path that would silently produce an empty env var and let the proxyrunner fall through to the (live-mounted) file value. Complements the unit-level TestDeploymentForMCPServer_MCPServerGenerationDownwardAPI and TestTryLoadConfigFromFile_MCPServerGenerationEnvOverride. Part of #5360. Co-Authored-By: Claude Opus 4.7 (1M context) * Address review feedback on #5360 freeze - Defend applyMCPServerGenerationOverride against negative env values. metadata.generation is monotonic non-negative per K8s convention, so a negative override cannot come from a legitimate downward-API projection and must not be allowed to silently disable the apply-gate stamp. Add a Debug log on the success path so the override is observable in pod logs when diagnosing future occurrences. - Add TestApplyMCPServerGenerationOverride exercising the empty, valid, zero, unparseable, and negative branches in isolation. - Soften the position-mirror comment in deploymentNeedsUpdate. The prior text referenced the Redis password slot, but deploymentNeedsUpdate does not include the Redis password env var (pre-existing latent drift bug, tracked separately). - Add a header comment to TestResourceOverrides explaining that the "0" mcpserver-generation annotation value comes from the fake client not auto-incrementing metadata.generation. Realistic generation tracking is exercised by the envtest in mcpserver_generation_freeze_integration_test.go. Co-Authored-By: Claude Opus 4.7 (1M context) * Fix CI: codespell typo and gofmt alignment - "unparseable" → "unparsable" (codespell) in run.go, run_test.go. - Realign env-var map literals to gofmt's preferred column for the longest key (THV_MCPSERVER_GENERATION). Co-Authored-By: Claude Opus 4.7 (1M context) * Set FieldRef.APIVersion=v1 to avoid perpetual drift ObjectFieldSelector.APIVersion is defaulted to "v1" by the API server on persistence. The drift comparator at deploymentNeedsUpdate was rebuilding the expected env var with an empty APIVersion, so equality.Semantic.DeepEqual returned false on every reconcile and the controller perpetually rewrote the proxy Deployment. That constant churn re-triggered the exact rolling- update race the freeze was supposed to close — confirmed by the failing VirtualMCPServer Optimizer + Circuit Breaker recovery spec in test-e2e-lifecycle: stale-image proxyrunner pods kept clobbering the new StatefulSet apply, leaving the backend mcp container in ImagePullBackOff. Explicitly set APIVersion: "v1" on both the construction site and the drift comparator so they match the API-server-defaulted value. Add unit-level assertion in TestDeploymentForMCPServer_MCPServerGenerationDownwardAPI and a new envtest spec "Does not flag spurious drift on a no-op reconcile" that watches the Deployment's resourceVersion across multiple reconciles and fails fast if drift detection misfires. Co-Authored-By: Claude Opus 4.7 (1M context) * TEMP debug: promote gate skip log + override log to INFO Temporary diagnostic for #5360 v1.33/v1.34 E2E failure. Will be reverted before merge. * Revert debug INFO logs; port STS-template wait to optimizer test The debug commit (8ed6e39e) confirmed the override + gate are working correctly end-to-end on a real cluster: pod env=3 (latest): file=3 env=3, apply proceeds — writes GOOD image pod env=2 (stale): file=3 env=2, gate skips (theirs=3 > ours=2) Revert the INFO promotion now that diagnosis is complete; both logs go back to Debug. The remaining E2E flake is a pre-existing race in virtualmcp_optimizer_circuit_breaker_test.go: the test deletes the Pending StatefulSet pod immediately after patching Spec.Image without waiting for the proxyrunner to apply the new template, so the pod can be recreated against the stale (bad) template and the StatefulSet controller may not re-roll an already-unhealthy pod afterwards. Mirrors the same guard added to virtualmcp_circuit_breaker_test.go in #5079. Before the apply-gate, the race "resolved" by the stale-image apply periodically resetting the template, letting the test catch a lucky good window. With the gate in place the apply order is deterministic, which makes the missing wait visible — hence the test fix lands here.

The controller reconciles status.storedVersions on opted-in toolhive.stacklok.dev CRDs by issuing a Get+Update against each CR, which re-encodes etcd objects to the current storage version. This is required before a future release can drop a deprecated apiVersion (e.g. v1alpha1) from spec.versions without orphaning rows. The flag defaults to false, so this PR has no functional impact for any user until they explicitly opt in via operator.env. Helm chart exposure (values.yaml flag entry and deployment env-var wiring) is deferred to a follow-up PR to reduce accidental enablement during the deprecation window. RBAC for the controller's verbs ships in this PR so the flag can be flipped on at any time without permission-denied errors. Opt-in label markers on the 12 v1beta1 root types and the marker-coverage CI test are deferred to a follow-up PR; the envtest suite creates its own CRDs at runtime and is independent of those changes. Part of #4969. Co-Authored-By: Claude Opus 4.7 (1M context) * Address PR review feedback - F1: fix doc comment claiming "Enabled by default" — the controller is default-off in this release, opt-in via env var only; chart surface lands in a follow-up PR - F2: fail loudly on unparsable env-var value instead of silently defaulting to disabled (per go-style "Fail Loudly") - F6: document why patchStoredVersions cannot use the operator-wide MutateAndPatchStatus helper (CRD storedVersions is co-owned with kube-apiserver, optimistic lock is load-bearing) - F7: demote disabled-state log from INFO to V(1) (silent success) - F8: prefix env var with TOOLHIVE_ to match sibling operator env vars and avoid cross-operator collisions - Codespell: unparseable→unparsable, overrideable→overridable - Chainsaw RBAC fixture: include the migrator's apiextensions verbs and the wildcard toolhive.stacklok.dev rules so the multi-tenancy setup assertion matches the regenerated ClusterRole Co-Authored-By: Claude Opus 4.7 (1M context) * Sync single-tenancy chainsaw RBAC fixture with regenerated ClusterRole Same update as the multi-tenancy fixture in the previous commit — single-tenancy/setup also snapshots the operator ClusterRole and the migrator's RBAC rules need to appear in its expected YAML too. Co-Authored-By: Claude Opus 4.7 (1M context) * Add unit tests for StorageVersionMigrator controller helpers Covers the parts of storageversionmigrator_controller.go that the envtest suite can't reach or only exercises transitively: migrationCache: TTL expiry with lazy eviction, RV mismatch as a miss, gc() evicting only expired entries, concurrent has/add/gc under the race detector, key uniqueness across CRDs and across UIDs, add() refreshing the expiry on existing entries. Pure predicate functions (isManagedCRD, isToolhiveCRDName, findStorageVersion, isMigrationNeeded): table-driven coverage of every input shape including edge cases the envtest suite would have to spin up an apiserver to exercise (nil labels, no storage version, empty storedVersions, multi-element storedVersions, etc.). Uses the migrationCache's existing `now func() time.Time` seam for frozen-clock TTL tests. No production code changes. Co-Authored-By: Claude Opus 4.7 (1M context) * Extend SVM unit tests to ensureInitialized and Reconcile early returns Adds unit tests for the cheaper of the previously-uncovered controller paths: ensureInitialized: defaults applied on zero values, explicit values preserved, idempotent across repeated calls. Reconcile early returns via the controller-runtime fake client: CRD IsNotFound, foreign group skip, missing opt-in label skip, no-storage-version skip, and already-clean storedVersions short-circuit. Brings file coverage from 25.4% to 41.3% (52/126 statements). The remaining uncovered functions (restoreCRs, restoreOne, patchStoredVersions, SetupWithManager) depend on apiserver-side behaviour that the fake client doesn't simulate — storage-encoder elision, optimistic-lock 409s, manager-driven watch wiring — so they stay in envtest territory. Co-Authored-By: Claude Opus 4.7 (1M context) * Add fake-client unit tests for restoreOne/restoreCRs/patchStoredVersions Covers the orchestration code paths in storageversionmigrator_controller.go that the envtest suite also tests, but at code-path level rather than apiserver-semantic level. The fake client can't simulate storage-encoder elision or optimistic-lock 409s, but it can verify: restoreOne: Get + Update propagation, NotFound on Get, Conflict on Update, generic error on Update. restoreCRs: happy path with cache population, empty list, per-CR NotFound silent skip, Conflict counted + sentinel returned, generic error aggregated, mixed conflicts+errors returns aggregate (not sentinel), first List failure wraps and returns immediately, cache hits skip Update, paginating reader confirms Continue token threads through ListOptions across three synthesized pages. patchStoredVersions: storedVersions trimmed in fake store on success, goes through /status subresource (not main resource), patch body carries resourceVersion (proof MergeFromWithOptimisticLock is in effect, not plain MergeFrom), patch errors propagate. File coverage: 41.3% → 77.8% (98/126 statements). - restoreOne, patchStoredVersions: 100% - restoreCRs: 92.3% - Reconcile: 56% (deep paths still envtest-only) - SetupWithManager: 0% (manager wiring not testable without a manager) Co-Authored-By: Claude Opus 4.7 (1M context) * Refactor SVM unit tests for conciseness Consolidates several test groups into table-driven form and trims redundant table cases without dropping any meaningful assertion or coverage. File shrinks 1261 → 1028 lines (~18%); coverage stays at 77.8% (98/126 statements on storageversionmigrator_controller.go). Notable consolidations: - 5 TestReconcile_* early-return tests → 1 table-driven TestReconcile_EarlyReturns - 3 TestRestoreOne_Propagates* tests → 1 table-driven TestRestoreOne_PropagatesErrors - 4 TestRestoreCRs_* error-classification tests → 1 table-driven TestRestoreCRs_ErrorClassification - 3 TestPatchStoredVersions_* success tests → 1 TestPatchStoredVersions_SuccessAssertsAllProperties - 2 cache key-collision tests → 1 TestMigrationCache_KeyIsolation - Dropped low-signal TestMigrationCache_GCNoopOnEmpty - Dropped duplicate helpers (newReconcileTestScheme, reconcileWithFake) - Trimmed redundant table cases in pure-function tests Co-Authored-By: Claude Opus 4.7 (1M context) * Address second-round PR review feedback (F1, F2, F3, F4, F5, F6) - F1: patchStoredVersions no longer mutates the caller's CRD. Writes the desired state to a deep-copy and uses the original as the merge-patch base. Honors go-style "Copy Before Mutating Caller Input". - F2: AutoMigrateLabel doc comment now reads "will be applied via a kubebuilder marker… in the follow-up PR" instead of falsely claiming the marker is already in place. - F3: Added a chart-consumer note to the RBAC-rationale block explaining that role.yaml's wildcard widens the operator SA's permissions on every install regardless of feature flag. Templating the rule behind a helm conditional is deferred to PR-C. (The reviewer's suggested template comment isn't viable — role.yaml is generated from kubebuilder markers and would lose hand-edits on regen.) - F4: Migrated from legacy k8s.io/client-go/tools/record + GetEventRecorderFor to k8s.io/client-go/tools/events + GetEventRecorder, matching every other reconciler in the package. Reconciler struct field, app.go wiring, three Reconcile call sites (new 7-arg signature), and the test doubles in both the unit-test and envtest files all updated. - F5: ensureInitialized is now wrapped in sync.Once. Provably safe under any number of callers (Setup, Reconcile, or future entrypoints) without dropping the Reconcile-side call that envtest helpers rely on. Addresses the future-race concern more comprehensively than the reviewer's "drop the call" suggestion would have. - F6: Reconcile no longer emits a Warning event when restoreCRs returns the conflict-retry sentinel. Conflicts are normal steady-state under concurrent writes and self-heal on the next reconcile, so the previous Warning event misrepresented routine retries as failures. Logs at V(1) and still returns the error so controller-runtime requeues. F7 (zero-means-default footgun) deliberately not actioned: the existing field comments already document the contract, and the Fail Loudly rule targets user-input constructors, not internal test seams. Co-Authored-By: Claude Opus 4.7 (1M context) * Address test-review feedback (T2, T3, T6, T7 + coverage gaps) T3: delete TestNewMigrationCache_InitializesUsableInstance — the constructor's struct literal is compiler-enforced; the add/has roundtrip is already covered by TestMigrationCache_AddThenHasReturnsTrue. T6: envtest pagination assertion now uses Equal(3) instead of BeNumerically(">=", 3). With 7 CRs at PageSize=3 the loop count is deterministically 3 — Equal pins the contract so a runaway over-fetch would fail the test. T7: cross-version envtest now asserts spec.marker survives the v1alpha1→v1beta1 re-encode. createCRs already writes the field; reading it back post-reconcile proves the apiserver's encode-decode round-trip preserves spec content, not just bumps RV. T2: renamed "migrates storedVersions from [v1alpha1,v1beta1] to [v1beta1]" → "succeeds end-to-end with elided updates when all CRs are already at storage version". Added countingAPIReader assertion (listCalls == 1) so the test self-documents that the list loop ran. Honest naming + non-trivial assertion. Coverage gap — context cancellation: new envtest spec cancels ctx before reconcile, asserts storedVersions stays intact. Guards against a future refactor that swallows ctx.Err() and trims anyway, which would orphan un-migrated CRs on operator shutdown. Coverage gap — event recording: cross-version test now uses events.NewFakeRecorder and asserts MigrationSucceeded fires; partial-failure test does the same for MigrationFailed. The two exported EventReason constants are public contract for operators consuming the CRD's Events stream. Skipped: T4 (TestRestoreCRs_EmptyListIsNoop) — asserts a real invariant (empty list ⇒ empty cache), not just range semantics. T5 (TestEnsureInitialized_AppliesDefaultsOnZeroValues) — exercises specific default values that indirect tests wouldn't catch. Co-Authored-By: Claude Opus 4.7 (1M context) * Fix lint findings on SVM unit tests - thelper: add t.Helper() to per-case check callbacks in TestRestoreOne_PropagatesErrors and TestRestoreCRs_ErrorClassification. Linter (correctly) flags any *testing.T-taking closure as a helper. - unparam: drop newCache(t, ttl) and makeTestCR(namespace, name) params. Every caller passed time.Hour / "default" respectively; hardcode and shrink the call sites. Co-Authored-By: Claude Opus 4.7 (1M context) * Fix codespell findings in SVM unit tests - "re-use" → "reuse" in a comment. - Rename optIn local var → optInLabels. The shorter name was being matched case-insensitively to "optin" → "option" by codespell; optInLabels is more descriptive anyway and dodges the false positive without adding a custom ignore wordlist. Co-Authored-By: Claude Opus 4.7 (1M context) * Update cmd/thv-operator/controllers/storageversionmigrator_controller.go Co-authored-by: Juan Antonio Osorio * Address JAORMX's PR review findings Six controller-side changes + two new tests, addressing valid findings from the multi-agent review. Bundled as one commit because findings #5 and #7 compose. RequeueAfter on the sentinel path. restoreOne now retries up to restoreOneMaxRetries=3 attempts when Update returns IsConflict, re-Getting the live object between attempts to refresh the resourceVersion. Reconcile returns ctrl.Result{RequeueAfter: 30s} with nil error when restoreCRs returns errMigrationRetriedDueToConflicts — this avoids controller-runtime's exponential backoff (5ms→16min) for what is normal steady-state behaviour under concurrent .status churn. Matches upstream kube-storage-version-migrator semantics. restoreOne. The list-page object is now passed directly to Update on the first attempt; retries (after IsConflict) still re-Get to refresh the RV. Halves apiserver read load. After sentinelConflictLogThreshold=5 consecutive sentinel passes the controller emits an INFO log so SREs have operator-visible signal that migration is not converging. Reset to zero on the next successful patchStoredVersions. toolhive.stacklok.dev/*/status. The migrator never writes to a toolhive CR's status subresource — patchStoredVersions targets the CRD's apiextensions.k8s.io status. Regenerated role.yaml; updated both chainsaw RBAC fixtures. comment. Admission webhooks fire on every Update, before the apiserver's bytes-equality check — only etcd writes + watch fanout are elided. The previous wording was materially wrong for any cluster running Kyverno/Gatekeeper. peak list-page memory from ~25MB to ~5MB inside the default 128Mi operator memory limit. never trims and no success event is emitted". Verifies the post-#5 contract: across 6 reconciles with one CR returning IsConflict every pass, err is nil, RequeueAfter=30s, storedVersions stays untrimmed, and no MigrationSucceeded event ever fires. table covering unset, explicit true/false, ParseBool truthy/falsy (1/0), unparseable typo, and empty string. Pins the F2 fail-loudly behaviour from the previous review round. Not actioned (rationale in code-review reply, not commit): - #8 (cache hooks untested) — review missed the existing unit tests for TTL expiry, GC eviction, and concurrent access in the unit-test file. No code change. - #2 (RBAC widening of previously-RO CRDs) — already documented in the PR body's "user-facing change" section. Will refine the PR body wording. - #4 full (metrics pipeline) — significant scope; deferred to follow-up issue. Light visibility piece landed in this commit. Co-Authored-By: Claude Opus 4.7 (1M context) * Recover lost controller changes from the previous rebase The previous "Address JAORMX's PR review findings" commit (b7c4116fd) shipped the *tests* for findings #4, #5, #6, #7 but accidentally dropped the *production code* that implements them. The rebase conflict resolution used `git checkout --ours` — but during a rebase "ours" means the branch being rebased onto, not the commits being applied, so the agent's controller-file changes were silently discarded. This commit restores them from the pre-rebase tree (7d063f28e): - #5: restoreOneMaxRetries=3 per-CR IsConflict retry in restoreOne; Reconcile returns ctrl.Result{RequeueAfter: 30s} with nil error on errMigrationRetriedDueToConflicts. - #7: list-page object passed directly to Update on attempt 0; fresh Get only on retry attempts. - #6: webhook-side-effects comment corrected. - #4 (light): per-CRD conflictPasses counter + INFO log after sentinelConflictLogThreshold=5 consecutive sentinel passes. The two existing envtest specs that already shipped against the NEW contract (`leaves storedVersions untouched when a CR re-store hits a Conflict, then trims on retry` and `under sustained conflict pressure...`) now pass because the production code matches what they assert. Co-Authored-By: Claude Opus 4.7 (1M context) * Fix CI failures from review-feedback commit - Spellcheck: rename "unparseable" → "unparsable" and replace the "ture" test fixture with "garbage" so codespell doesn't false-flag the deliberate-typo test case. - Chainsaw RBAC fixtures: re-sync to the regenerated role.yaml. Same rules but rule ordering differs; chainsaw asserts byte-exact match.

The label is the opt-in signal for an upcoming StorageVersionMigrator controller that will reconcile each CRD's status.storedVersions down to the current storage version. List types are intentionally not labelled — the label applies to the CRD itself, which is keyed on the root type. Part of #4969. Co-Authored-By: Claude Opus 4.7 (1M context) * Add CI test enforcing migrate-label coverage on v1beta1 root types Guards against the main footgun of the opt-in-label design for storage-version migration: if a new CRD root type is added to cmd/thv-operator/api/v1beta1/ without the migrate-marker, the StorageVersionMigrator controller silently excludes it. The problem surfaces only when a future release tries to drop a deprecated version — at which point it is far too late to fix. The test scans every root type (marker block contains both +kubebuilder:object:root=true and +kubebuilder:storageversion) and fails unless the block also contains either the migrate marker or an explicit +thv:storage-version-migrator:exclude sibling marker. Part of #4969. Co-Authored-By: Claude Opus 4.7 (1M context) * Scan all api/v* directories, label MCPWebhookConfig The marker-coverage test was only scanning cmd/thv-operator/api/v1beta1/ and filtering for files matching *_types.go. This had two gaps: 1. Future graduations (v1beta1 → v1beta2) would silently break the test: when +kubebuilder:storageversion moves to v1beta2/, the v1beta1 root types lose the storage marker and become invisible to the scanner. The test would either pass vacuously (other version dirs unscanned) or hard-fail on the "no roots found" guard with no clear path forward. 2. MCPWebhookConfig lives in api/v1alpha1/types.go (not _types.go) and carries +kubebuilder:storageversion as the only never-graduated CRD. The original PR-B commit skipped it entirely; the migrator could not act on its CRs even when explicitly opted in. Changes: - Walk cmd/thv-operator/api/v*/ instead of hardcoding v1beta1. - File filter accepts both exact "types.go" and "*_types.go" suffix. - Rename TestV1beta1TypesMarkerCoverage → TestStorageVersionRootMarkerCoverage. - Update failure message + docstring to reflect the broader scope. - Add the migrate marker to MCPWebhookConfig in v1alpha1/types.go and regenerate its two CRD YAML files under deploy/charts/operator-crds/. Future-proof: when v1beta2 lands and +kubebuilder:storageversion moves to its root types, the scanner picks them up without code changes here. Co-Authored-By: Claude Opus 4.7 (1M context) * Drop the exclude marker — every storage root must opt in The previous test accepted either the migrate marker or an explicit +thv:storage-version-migrator:exclude sibling. That permissive contract opens a graduation-time hole: a single-version CRD created with exclude passes CI, but at v1→v2 graduation time the developer has to remember to swap exclude→migrate. Forgetting the swap leaves the CRD silently un-migrated — exactly the failure mode this test is meant to prevent. No CRD in the codebase uses the exclude marker today. Removing it costs nothing and closes the hole. If a legitimate exclusion ever comes up, handle it as a one-off PR conversation and a hardcoded allowlist in this test — not a self-serve marker that future contributors can misuse. Co-Authored-By: Claude Opus 4.7 (1M context) * Tighten marker match to whole-token boundary + stub allowlist Two defensive additions identified during stress-testing the opt-in-label design: 1. Strict marker matching. containsMarker previously used strings.Contains, which would accept "=truee" (or any extra character) as a substring match for "=true". The CI test would pass, the generated CRD YAML would carry label value "truee", and the controller's runtime check (labels[key] == "true") would silently exclude the CRD. The bug only surfaces at version-drop time months later. containsMarker now requires the marker to be followed by end-of-line or whitespace. TestContainsMarkerStrictBoundary defends the contract against future regressions to substring semantics. 2. excludedRootTypes allowlist stub. The previous commit removed the self-serve +thv:storage-version-migrator:exclude marker. This adds the documented alternative — a hardcoded allowlist in the test file — as an empty map with an example entry and a comment explaining the deliberate, reviewed-decision policy for adding entries. If a future contributor needs to exclude a CRD, the path is "add an entry, justify it in PR review"; they don't have to invent the mechanism from scratch. Co-Authored-By: Claude Opus 4.7 (1M context) * Address review nits: marker order + drop pre-1.22 loop shadow - v1alpha1/types.go MCPWebhookConfig: move the migrate marker to AFTER +kubebuilder:subresource:status, matching the v1beta1 convention. controller-gen ignores order so behaviour is unchanged; this is purely consistency for greppability and future readers. - marker_coverage_test.go: drop `tc := tc` shadowing in TestContainsMarkerStrictBoundary. go.mod is on go 1.26; loop variables have been per-iteration since 1.22, so the shadow is dead code from older-Go muscle memory. go/ast or controller-tools/pkg/markers refactor (raised separately) deliberately deferred: the bufio scanner is correct for every CRD in the codebase today; switching to AST is a ~40-line restructure better landed as a follow-up if/when we actually need generics or grouped type decl support in a CRD.

May 2026 13:56:40 +0300 Subject: [PATCH 230/291] Add 'thv mcp call' for invoking MCP server tools (#5389) Listing tools via 'thv mcp list' showed what an MCP server exposes but not how it behaves. Adding 'thv mcp call' lets the user open a session, invoke a named tool, and inspect the result without leaving the CLI -- useful for ad-hoc debugging, registry verification, and shell pipelines. The subcommand accepts a positional tool name, server URL or workload name via --server, and JSON arguments via --args, --args-file, or stdin (--args-file -). Output is rendered in text by default or as the full CallToolResult in JSON. Tool-level errors exit non-zero by default; --ignore-tool-error inverts that for pipelines that want to inspect the result regardless.

Hanson" Date: Mon, 1 Jun 2026 09:56:38 -0500 Subject: [PATCH 235/291] Fall back to request-token claims for opaque upstream tokens (#5147) VirtualMCPServer (Cedar incoming authz) denied every request when the embedded auth servers upstream provider issues opaque OAuth 2.0 access tokens (Googles ya29.*, GitHubs gho_*). resolveClaims tried to JWT-parse the upstream token unconditionally and returned the parse error verbatim, so every authorization check failed and the gateway skipped every tool. Discriminate by token shape: if the upstream token is not three dot- separated segments it cannot be a JWT, so fall back to identity.Claims (the request-token claims). The embedded auth server already mirrors the upstream OIDC sub, email and name into its issued AS token (see pkg/authserver/server/session/session.go), so policies referencing standard OIDC claims continue to evaluate correctly. JWT-shaped tokens (three segments) that fail to parse still return the error: a tampered or corrupted upstream JWT must not silently degrade to fallback claims. Closes #5146 Signed-off-by: Cody J.

For tests this clobbered the developer's real config file whenever a PathProvider loaded a temp config with a secrets provider set but setup_completed false, defeating the isolation added for #894.

CI passed only because no server is running there. Inject the discovery step into newDefaultClientWithEnv, mirroring the existing env.Reader injection, and have the subtests stub it. Each resolution step (env var, discovery, default fallback) is now tested in isolation, and a new subtest covers the discovered-server path.

It already handled the suffix-append form (e.g. https://mcp.atlassian.com/.well-known/oauth-authorization-server → https://mcp.atlassian.com) and the issuer-suffix multi-tenant style (.../tenants/acme/.well-known/openid-configuration → .../tenants/acme), but the comment block explicitly opted out of the RFC 8414 §3.1 path-insertion form — operators on that pattern had to fall back to `dcr_config.registration_endpoint` to bypass discovery entirely. That gap rejects providers that publish a path-component issuer per the letter of the RFC. Datadog's MCP authorization server is one such provider: its discovery URL `https://mcp.us5.datadoghq.com/.well-known/oauth-authorization-server/v1/mcp` declares issuer `https://mcp.us5.datadoghq.com/v1/mcp`, and DCR discovery aborts with: issuer mismatch (RFC 8414 §3.3): expected "https://mcp.us5.datadoghq.com", got "https://mcp.us5.datadoghq.com/v1/mcp" Recognise the path-insertion form by checking for the well-known segment as a path *prefix* followed by a tenant path (HasPrefix(path, suffix+"/")), trimming just the well-known segment to recover origin + tenant path. Disambiguated from the existing suffix-append case by position: the well-known segment at the end of the path is suffix-append; at the start with more path following is path-insertion. The two cases cannot both match a single URL. Tests cover the new branch for both the OAuth and OIDC suffix variants plus a multi-segment tenant. All existing cases continue to pass. Per RFC 8414 §3 (the well-known URI is formed by inserting the well-known suffix between host and path of the issuer) and RFC 8615 (well-known URI conventions). Signed-off-by: Juzer Patanwala * dcr: normalise trailing-slash bare well-known to origin (review feedback) Per @tgrunnagle's review on #5395: the path-insertion arms introduced in the previous commit accidentally regress one edge case. For an input where the path ends `/.well-known/oauth-authorization-server/` (trailing slash, no tenant), the suffix arms don't match (suffix test sees the trailing "/"), so the HasPrefix arm fires and TrimPrefix leaves `u.Path = "/"` → spurious issuer `https://host/` that fails the §3.3 byte-equality check against the upstream's declared `https://host`. Before this PR the same input hit the `default` arm and produced `https://host` correctly. Fix: after TrimPrefix in each path-insertion arm, collapse a lone `/` back to empty so the trailing-slash form converges on the same origin issuer the bare-suffix and `default` arms produce. Tightens the inline comment to describe both shapes that reach the HasPrefix arm (real tenant suffix and trailing-slash). Adds two table-driven cases — one each for the oauth and oidc trailing-slash forms — to lock in the expected origin output.

Introduce a backend package that all clients can consume. Add pkg/workloads/upgrade with a Checker that compares a running workload's image tag against its registry entry (semver-aware, with a string fallback) and reports environment-variable and configuration (transport / permission-profile / network-isolation) drift. Comparison degrades safely to "unknown" for :latest, digest refs, repository changes, and non-registry-sourced workloads, so only a strictly-newer tag on the same repository yields "upgrade-available". This is the read-only detection core (RFC THV-0068, phase A); the apply path, API endpoints, and CLI follow in later changes. Co-Authored-By: Claude Opus 4.8 (1M context) * Address review feedback on upgrade detection - Lowercase an uppercase "V" tag prefix so semver comparison works; "V1.2.0" vs "V1.3.0" no longer falls through to undecidable and hides a real upgrade. - Drop the raw provider error from CheckResult.Reason (it is serialized into the API response and can leak internal addressing); log it at DEBUG and return a fixed string. Same for the CheckAll path. - Add a defensive default to the comparison switch so an unexpected value yields StatusUnknown rather than the least-safe StatusUpToDate. - Stop reporting network-isolation drift: the registry has no network-isolation field, so it fired for every isolated workload regardless of the candidate version. Remove the ConfigDrift field and the now-unused BoolChange type.

From bedd6ba93184ffad820207adc9586e541f5175e2 Mon Sep 17 00:00:00 2001 From: Jakub Hrozek Date: Tue, 2 Jun 2026 11:47:28 +0100 Subject: [PATCH 240/291] Bind vMCP sessions to OIDC identity, not raw token bytes (#5378) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Add pkg/vmcp/session/binding leaf package The vMCP session-binding format needs to be parsed and produced in two places: pkg/vmcp/session/types (from ShouldAllowAnonymous) and pkg/vmcp/session/internal/security (from BindSession / validateCaller). A private helper in each would drift over time, so this commit introduces a single-owner leaf package. Format encodes a bound identity as iss + "\x00" + sub, rejecting empty halves and stray NULs. Parse mirrors Format strictly — including rejecting trailing NULs in the sub half so values that did not pass through Format (e.g. direct writes to Redis) fail loudly. A literal "unauthenticated" sentinel covers sessions created without an authenticated identity. No callers wired yet — those land in the next commits. Co-Authored-By: Claude Opus 4.7 * Add MetadataKeyIdentityBinding key and tighten ShouldAllowAnonymous The hijack-prevention decorator needs a stable per-identity key in session metadata. Add MetadataKeyIdentityBinding alongside the existing token-hash keys (the legacy keys stay temporarily so already-running sessions can be invalidated cleanly during the migration; final removal happens in the operator-side follow-up). ShouldAllowAnonymous treated every empty-token identity as anonymous, which lumped LocalUserMiddleware identities into the same equivalence class even when they carried distinct (iss, sub) claims — letting one local user reuse another's session ID. Tighten the rule so any identity with a valid (iss, sub) pair from Claims goes through the bound path, even when Token is empty. Pull iss and sub from Identity.Claims rather than Identity.Subject so the introspection path and the JWT path canonicalize against the same source. Fail-closed on non-string iss/sub claims: a misbehaving validator that stores a numeric or array value is treated as bound (not anonymous), with a WARN logged so the misbehavior surfaces to operators. The new key is unused until the security and factory layers are wired in the next commit. Co-Authored-By: Claude Opus 4.7 * Bind sessions to (iss, sub), not raw token bytes The hijack-prevention decorator hashed the incoming bearer token at session creation and rejected any subsequent request whose token hashed differently. Every legitimate OAuth refresh produces a new access token with different bytes — same identity, same iss, same sub — so the decorator misclassified the refresh as a hijack and terminated the session with Unauthorized: caller identity does not match session owner. Drop the HMAC plumbing entirely and bind to a stable (iss, sub) tuple extracted from the OIDC identity's Claims. The binding lives in session metadata under MetadataKeyIdentityBinding, written exclusively by the new BindSession constructor (renamed from PreventSessionHijacking). Validation reads the caller's claims through the same path so the JWT and introspection code paths canonicalize against the same source. The session-upgrade defense (anonymous session, caller presents a token) moves to the unauthenticated-sentinel branch and works exactly as before. RestoreSession reconstructs identity from the stored binding rather than from a separate identity-subject key. Sessions written under the legacy token-hash schema return the bare transportsession.ErrSessionNotFound sentinel so the client receives the standard "re-initialise" signal one forced re-auth at deploy is preferable to a rebind-on-first-use window that would re-introduce the hijack the check exists to block. Downstream callers of the removed WithHMACSecret option (cli/serve.go) and the Phase-2 marker switch (sessionmanager) follow in the next commits; tests catch up after that. Co-Authored-By: Claude Opus 4.7 Use MetadataKeyIdentityBinding as the Phase-2 marker BindSession writes MetadataKeyIdentityBinding on every successful session creation (sentinel for anonymous, real binding for authenticated), so its presence is the new way to distinguish a fully-initialised Phase-2 session from a Generate()-only placeholder. Without this swap, the now-unwritten MetadataKeyTokenHash would always read as absent and Terminate would take the placeholder path on every session, breaking termination semantics. The behaviour for legacy sessions still in Redis from before the migration is intentional and documented in the plan: Terminate writes the placeholder-terminated marker (Update with MetadataKeyTerminated) which sits for the TTL; loadSession returns transportsession.ErrSessionNotFound so the client transparently re-initialises. Co-Authored-By: Claude Opus 4.7 * Drop HMAC plumbing from serve.go; document Redis trust boundary createSessionFactory no longer takes an HMAC secret or a Kubernetes detection flag. VMCP_SESSION_HMAC_SECRET stays readable from the environment for one deploy cycle (DEBUG-logged and ignored) so the operator-side env-var injection can be removed in a follow-up PR without forcing a coordinated cut-over. Add a startup WARN when incoming auth is configured as "anonymous": AnonymousMiddleware populates the same (iss, sub) for every request, so all callers collide on one identity binding and per-identity hijack prevention degrades to dev-only behaviour. Surface that to operators rather than letting them assume the binding still scopes per user. Document the trust boundary in docs/arch/13-vmcp-scalability.md: the new scheme stores plaintext (iss, sub) at rest in Redis/Valkey, which trades the HMAC's at-rest opacity for refresh correctness. Operators must layer Redis ACLs or NetworkPolicies if a Redis dump revealing identity is unacceptable. Add a TODO on extractBindingID for the forward-looking RFC 7662 case (probe IdP introspection responses for iss + sub) so it surfaces if that becomes a top-level incoming-auth type. The five HMAC-specific serve_test.go cases collapse to one table-driven test of the new signature; the removed cases targeted HMAC validation that no longer exists.

Introduce a backend package that all clients can consume. Add pkg/workloads/upgrade with a Checker that compares a running workload's image tag against its registry entry (semver-aware, with a string fallback) and reports environment-variable and configuration (transport / permission-profile / network-isolation) drift. Comparison degrades safely to "unknown" for :latest, digest refs, repository changes, and non-registry-sourced workloads, so only a strictly-newer tag on the same repository yields "upgrade-available". This is the read-only detection core (RFC THV-0068, phase A); the apply path, API endpoints, and CLI follow in later changes. Co-Authored-By: Claude Opus 4.8 (1M context) * Address review feedback on upgrade detection - Lowercase an uppercase "V" tag prefix so semver comparison works; "V1.2.0" vs "V1.3.0" no longer falls through to undecidable and hides a real upgrade. - Drop the raw provider error from CheckResult.Reason (it is serialized into the API response and can leak internal addressing); log it at DEBUG and return a fixed string. Same for the CheckAll path. - Add a defensive default to the comparison switch so an unexpected value yields StatusUnknown rather than the least-safe StatusUpToDate. - Stop reporting network-isolation drift: the registry has no network-isolation field, so it fired for every isolated workload regardless of the candidate version. Remove the ConfigDrift field and the now-unused BoolChange type. Co-Authored-By: Claude Opus 4.8 (1M context) * Add upgrade-check REST endpoints for workloads CLI, Studio, and automation need a single backend source of truth for upgrade availability instead of each client reimplementing registry drift detection. Expose the Phase A checker over the existing workloads API. Add GET /api/v1beta/workloads/upgrade-check (batch) and GET /api/v1beta/workloads/{name}/upgrade-check (single). The batch handler reuses the exact group/all authorization scoping of the list endpoint and intersects it with the enumerated run configs, so it can never report a workload outside the caller's scope. Responses carry only non-sensitive CheckResult metadata; secret env-var defaults are cleared. Both routes are read-only and skip image pulls, so they use the standard timeout. Regenerate the OpenAPI spec. The dedicated apply endpoint (POST .../upgrade) follows once the Applier lands (RFC THV-0068, phase B). Co-Authored-By: Claude Opus 4.8 (1M context) * Return 404 for unknown group in workload listing FilterByGroup returns an empty slice (nil error) for a group that does not exist, so a typo'd ?group= silently returned 200 with an empty list instead of the documented 404. Check group existence explicitly via the group manager before filtering, in both the upgrade-check and the listWorkloads handlers, so the advertised 404 is real. Add a bulk upgrade-check test covering the unknown-group path. Co-Authored-By: Claude Opus 4.8 (1M context) * Regenerate OpenAPI spec after dropping network-isolation drift The upgrade detection change removed the ConfigDrift.NetworkIsolation field and the BoolChange type, so regenerate the committed OpenAPI spec to drop the stale schema and property. Fixes the Verify Swagger Documentation CI check.

Introduce a backend package that all clients can consume. Add pkg/workloads/upgrade with a Checker that compares a running workload's image tag against its registry entry (semver-aware, with a string fallback) and reports environment-variable and configuration (transport / permission-profile / network-isolation) drift. Comparison degrades safely to "unknown" for :latest, digest refs, repository changes, and non-registry-sourced workloads, so only a strictly-newer tag on the same repository yields "upgrade-available". This is the read-only detection core (RFC THV-0068, phase A); the apply path, API endpoints, and CLI follow in later changes. Co-Authored-By: Claude Opus 4.8 (1M context) * Address review feedback on upgrade detection - Lowercase an uppercase "V" tag prefix so semver comparison works; "V1.2.0" vs "V1.3.0" no longer falls through to undecidable and hides a real upgrade. - Drop the raw provider error from CheckResult.Reason (it is serialized into the API response and can leak internal addressing); log it at DEBUG and return a fixed string. Same for the CheckAll path. - Add a defensive default to the comparison switch so an unexpected value yields StatusUnknown rather than the least-safe StatusUpToDate. - Stop reporting network-isolation drift: the registry has no network-isolation field, so it fired for every isolated workload regardless of the candidate version. Remove the ConfigDrift field and the now-unused BoolChange type. Co-Authored-By: Claude Opus 4.8 (1M context) * Add upgrade-check REST endpoints for workloads CLI, Studio, and automation need a single backend source of truth for upgrade availability instead of each client reimplementing registry drift detection. Expose the Phase A checker over the existing workloads API. Add GET /api/v1beta/workloads/upgrade-check (batch) and GET /api/v1beta/workloads/{name}/upgrade-check (single). The batch handler reuses the exact group/all authorization scoping of the list endpoint and intersects it with the enumerated run configs, so it can never report a workload outside the caller's scope. Responses carry only non-sensitive CheckResult metadata; secret env-var defaults are cleared. Both routes are read-only and skip image pulls, so they use the standard timeout. Regenerate the OpenAPI spec. The dedicated apply endpoint (POST .../upgrade) follows once the Applier lands (RFC THV-0068, phase B). Co-Authored-By: Claude Opus 4.8 (1M context) * Return 404 for unknown group in workload listing FilterByGroup returns an empty slice (nil error) for a group that does not exist, so a typo'd ?group= silently returned 200 with an empty list instead of the documented 404. Check group existence explicitly via the group manager before filtering, in both the upgrade-check and the listWorkloads handlers, so the advertised 404 is real. Add a bulk upgrade-check test covering the unknown-group path. Co-Authored-By: Claude Opus 4.8 (1M context) * Regenerate OpenAPI spec after dropping network-isolation drift The upgrade detection change removed the ConfigDrift.NetworkIsolation field and the BoolChange type, so regenerate the committed OpenAPI spec to drop the stale schema and property. Fixes the Verify Swagger Documentation CI check. Co-Authored-By: Claude Opus 4.8 (1M context) * Add thv upgrade check and list --check-upgrades CLI users had no way to see whether their registry-sourced MCP servers have newer versions available. Surface the upgrade checker on the command line. Add a thv upgrade command group with a check [name] subcommand: with a name it prints a verbose report (candidate image, new env vars, and permission/transport/network posture drift); with no name it prints a table for all workloads. Add an opt-in --check-upgrades flag to thv list that appends an upgrade column. Both reuse the pkg/workloads/upgrade checker and only format results; the default list path is unchanged and performs no registry lookup, so it stays offline-friendly. Bulk output is sorted by name to match thv list. Co-Authored-By: Claude Opus 4.8 (1M context) * Address review feedback on upgrade CLI - Reject --check-upgrades together with --format mcpservers: that format has no upgrade column, so the combination performed a registry lookup per workload and discarded the result. Fail loudly in PreRunE instead. - Guard the bulk-result loop against nil entries so it stays robust if CheckAll's contract ever changes. - Drop the network-isolation line from the posture-drift report; the checker no longer reports it (the registry has no such field).

Add the apply path that the CLI and API will drive. Add upgrade.Applier: it reloads the workload's saved config, re-runs the check on fresh state (so a stale result can never drive an apply), resolves the candidate from the registry, and rebuilds the run config preserving the full user configuration — auth, authz, audit, telemetry, tools filters, volumes, secrets, ports, permission profile, and more — changing only the image, merged env/secrets, and re-resolved registry URLs. New required env vars surface through the injected validator. Crucially, the candidate image is verified and pulled (and the policy gate runs) before the destructive stop/delete/start, so a missing or unverifiable image leaves the running workload untouched — there is no rollback once UpdateWorkload begins. Verification uses the same path as thv run.

Uses registration.ValidateScopes (same function as the DCR handler) to validate declared scopes against the AS allowlist and compute the effective scope list. When ScopesSupported is unset, the document's declared scopes are used directly; omitted scopes default to DefaultScopes. C4 - Reject CIMD documents that declare grant_types or response_types the embedded AS does not support for public clients (authorization_code + refresh_token; code). Consistent with DCR which returns invalid_client_metadata for the same cases. buildFositeClient now receives pre-computed scopes from fetch() rather than re-parsing doc.Scope, matching the DCR handler pattern where scope computation and validation happen before client construction. Co-Authored-By: Claude Sonnet 4.6 (1M context) * Address tgrunnagle review feedback on CIMD validation F1 Move TestUnionScopes to registration package where UnionScopes lives; delete now-empty handlers/scopes.go and handlers/scopes_test.go F2 Add assert.ErrorIs(ErrInvalidClient)/NotErrorIs(ErrNotFound) to all CIMD policy rejection tests to pin the error type change F4 Replace 6 positional NewCIMDStorageDecorator args with CIMDDecoratorConfig struct — prevents silent swap of adjacent []string F5 Omitted-scope now calls ValidateScopes(nil, scopesSupported) matching DCR: returns DefaultScopes when DefaultScopes ⊆ ScopesSupported, error otherwise (document must declare scope explicitly) F6 Fix dcrErr.Error → dcrErr.ErrorDescription in scope validation hint so the human-readable description reaches the fosite hint field F7 slices.Clone scope slices in CIMDDecoratorConfig constructor F8 Fix buildFositeClient doc: "when empty" not "when nil" F9 Export ValidatePublicGrantTypes/ValidatePublicResponseTypes from registration package; replace hand-rolled loops in cimd_decorator.go with calls to these shared validators — grant_type/response_type validation is now identical on both DCR and CIMD paths F10 Rename AcceptsSupportedGrantTypes→AcceptsOmittedGrantTypes and RejectsRefreshTokenOnly→RejectsGrantTypesMissingAuthorizationCode F11 Remove redundant TestBuildFositeClient_ScopeDefaultsToScopesSupported (real decision lives in fetch(), not buildFositeClient) F12 Update slog.Warn message to name the security consequence when CIMD+BaselineClientScopes are both configured Co-Authored-By: Claude Sonnet 4.6 (1M context) --------- Co-authored-by: Claude Sonnet 4.6 (1M context) --- pkg/authserver/server/handlers/authorize.go | 4 +- pkg/authserver/server/handlers/dcr.go | 2 +- pkg/authserver/server/handlers/scopes.go | 38 --- pkg/authserver/server/handlers/scopes_test.go | 115 --------- pkg/authserver/server/registration/dcr.go | 44 ++++ .../server/registration/dcr_test.go | 28 +++ pkg/authserver/server_impl.go | 14 +- pkg/authserver/storage/cimd_decorator.go | 136 ++++++++--- pkg/authserver/storage/cimd_decorator_test.go | 221 ++++++++++++++++-- 9 files changed, 398 insertions(+), 204 deletions(-) delete mode 100644 pkg/authserver/server/handlers/scopes.go delete mode 100644 pkg/authserver/server/handlers/scopes_test.go diff --git a/pkg/authserver/server/handlers/authorize.go b/pkg/authserver/server/handlers/authorize.go index dece4979ad..ba767e88c9 100644 --- a/pkg/authserver/server/handlers/authorize.go +++ b/pkg/authserver/server/handlers/authorize.go @@ -66,7 +66,9 @@ func (h *Handler) AuthorizeHandler(w http.ResponseWriter, req *http.Request) { return } - slog.Debug("parsed client-requested scopes", //nolint:gosec // G706: scope count is an integer + slog.Debug("authorize request received", + "client_id", clientID, + "redirect_uri", redirectURI, "scope_count", len(scopes), ) diff --git a/pkg/authserver/server/handlers/dcr.go b/pkg/authserver/server/handlers/dcr.go index bd9f8ef4df..f7dabed355 100644 --- a/pkg/authserver/server/handlers/dcr.go +++ b/pkg/authserver/server/handlers/dcr.go @@ -77,7 +77,7 @@ func (h *Handler) RegisterClientHandler(w http.ResponseWriter, req *http.Request // offline_access) — every DCR-registered client gains the ability to request // these scopes at /oauth/authorize regardless of what they registered with. if len(h.config.BaselineClientScopes) > 0 { - effective := unionScopes(scopes, h.config.BaselineClientScopes) + effective := registration.UnionScopes(scopes, h.config.BaselineClientScopes) if !slices.Equal(effective, scopes) { // Baseline-driven expansion is the intended behavior whenever // baseline_client_scopes is configured, so per-registration diff --git a/pkg/authserver/server/handlers/scopes.go b/pkg/authserver/server/handlers/scopes.go deleted file mode 100644 index 6f4705c25b..0000000000 --- a/pkg/authserver/server/handlers/scopes.go +++ /dev/null @@ -1,38 +0,0 @@ -// SPDX-FileCopyrightText: Copyright 2025 Stacklok, Inc. -// SPDX-License-Identifier: Apache-2.0 - -package handlers - -// unionScopes returns the union of requested and baseline scopes, preserving -// the order of requested first, then appending any baseline scopes not already -// present.

[PATCH 246/291] Add upgrade apply for the CLI and API (#5411) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Add Applier for upgrading workloads in place Detecting an available upgrade is only useful if users can apply it while keeping their configuration. Add the apply path that the CLI and API will drive. Add upgrade.Applier: it reloads the workload's saved config, re-runs the check on fresh state (so a stale result can never drive an apply), resolves the candidate from the registry, and rebuilds the run config preserving the full user configuration — auth, authz, audit, telemetry, tools filters, volumes, secrets, ports, permission profile, and more — changing only the image, merged env/secrets, and re-resolved registry URLs. New required env vars surface through the injected validator. Crucially, the candidate image is verified and pulled (and the policy gate runs) before the destructive stop/delete/start, so a missing or unverifiable image leaves the running workload untouched — there is no rollback once UpdateWorkload begins. Verification uses the same path as thv run. Co-Authored-By: Claude Opus 4.8 (1M context) * Add upgrade apply for the CLI and API With the Applier in place, expose it to users. This lets CLI users and API clients apply an upgrade while preserving their configuration, instead of manually re-running a workload with a new image. Add a thv upgrade apply command. It runs the check, shows the candidate image, new env vars, and any permission/transport/network posture drift, then prompts for confirmation. --dry-run reports the plan without applying; --env/--secret supply values for newly required variables; --yes (or a non-interactive shell) skips the prompt and fails loudly on missing required values; --image-verification mirrors thv run. Add POST /api/v1beta/workloads/{name}/upgrade, delegating to the same Applier so all clients share one apply path. The API path is always non-interactive (detached validator) and sources image verification from server config; the request body can only supply env/secret values, never redirect the image or weaken verification. Apply failures return a sanitized 422 with the detailed cause logged server-side, so secret references in an error chain are never echoed to the caller.

Add the apply path that the CLI and API will drive. Add upgrade.Applier: it reloads the workload's saved config, re-runs the check on fresh state (so a stale result can never drive an apply), resolves the candidate from the registry, and rebuilds the run config preserving the full user configuration — auth, authz, audit, telemetry, tools filters, volumes, secrets, ports, permission profile, and more — changing only the image, merged env/secrets, and re-resolved registry URLs. New required env vars surface through the injected validator. Crucially, the candidate image is verified and pulled (and the policy gate runs) before the destructive stop/delete/start, so a missing or unverifiable image leaves the running workload untouched — there is no rollback once UpdateWorkload begins. Verification uses the same path as thv run. Co-Authored-By: Claude Opus 4.8 (1M context) * Add upgrade apply for the CLI and API With the Applier in place, expose it to users. This lets CLI users and API clients apply an upgrade while preserving their configuration, instead of manually re-running a workload with a new image. Add a thv upgrade apply command. It runs the check, shows the candidate image, new env vars, and any permission/transport/network posture drift, then prompts for confirmation. --dry-run reports the plan without applying; --env/--secret supply values for newly required variables; --yes (or a non-interactive shell) skips the prompt and fails loudly on missing required values; --image-verification mirrors thv run. Add POST /api/v1beta/workloads/{name}/upgrade, delegating to the same Applier so all clients share one apply path. The API path is always non-interactive (detached validator) and sources image verification from server config; the request body can only supply env/secret values, never redirect the image or weaken verification. Apply failures return a sanitized 422 with the detailed cause logged server-side, so secret references in an error chain are never echoed to the caller. Co-Authored-By: Claude Opus 4.8 (1M context) * Add e2e coverage and lifecycle docs for upgrades The upgrade flow spans registry lookup, image verification, and a destructive workload recreate, so it needs end-to-end coverage to catch regressions the unit tests cannot. Add an e2e test that exercises the full flow against real osv-mcp image tags via custom registry fixtures: a workload run from the 0.1.1 entry reports up-to-date, repointing the registry to 0.1.3 makes the check report an available upgrade, and apply recreates the workload on the new image while preserving a user-set env var. A negative spec confirms a raw-image workload reports not-registry-sourced. All thv invocations run under an isolated config/home/data dir so the suite never touches the developer's real registry configuration. Document the upgrade state transition in the workloads lifecycle architecture doc.

Upstream now ships the maintained client and API types as the split modules github.com/moby/moby/client and github.com/moby/moby/api, both of which ToolHive already requires. Migrate pkg/container/docker and pkg/container/images off github.com/docker/docker/{client,api/types,pkg/stdcopy} and github.com/docker/go-connections/nat onto github.com/moby/moby/client and github.com/moby/moby/api. The new client exposes a redesigned surface, so call sites are adapted to the per-operation Options/Result structs, the client.Filters type, the network.Port struct (replacing the nat.Port string), and netip.Addr host addresses, while preserving existing behavior. After this change the production build no longer imports github.com/docker/docker; it remains only as an indirect test dependency via testcontainers-go. Drop the now-dormant govulncheck ignore entries for GO-2026-4883 and GO-2026-4887. These daemon-side Moby advisories are no longer in govulncheck's called set once docker/docker is off the production build, so the suppressions are no longer needed. Also drop the stale GO-2026-4514 entry: buger/jsonparser is no longer in the module graph, so that ignore is dead.

CI builds with `setup-go: stable`, which still resolves to go1.26.3 because the actions/go-versions manifest lags the release, so govulncheck flags them on code we do not control. Add the three OSV IDs to the documented IGNORED_VULNS exclusion list to unblock CI. This is temporary and should be removed once CI builds on go1.26.4 or later.

Bump every affected action to a release that runs on Node.js 24. All are runtime-only major bumps with no input or behavior changes for our usage: - azure/setup-helm v4.3.1 -> v5.0.0 - docker/login-action v3.7.0 -> v4.2.0 - docker/setup-buildx-action v3.12.0 -> v4.1.0 - docker/metadata-action v5.10.0 -> v6.1.0 - docker/build-push-action v6.19.2 -> v7.2.0 - codecov/codecov-action v5 -> v6.0.1 (also moves its embedded github-script v7 -> v8) - slackapi/slack-github-action v2.1.1 -> v3.0.3 arduino/setup-task and golang/govulncheck-action are left as-is: neither has a Node.js 24 release yet.

Add a lazy parameter to llm.Setup that skips only the interactive login. Tool detection, config-file patching, and config persistence still run, so the on-disk result is identical to a normal setup except that no OIDC token is obtained yet — login is deferred to first gateway access. The sole call site passes false for now; the --lazy CLI flag is wired in a later change. Co-Authored-By: Claude Opus 4.8 (1M context) * Add --lazy flag and make llm token interactive Wire the lazy parameter added to llm.Setup to a new --lazy flag on "thv llm setup", so unattended provisioning can configure tools without the interactive OIDC browser login. For deferred login to be transparent, "thv llm token" now builds an interactive token source: on a genuine cache miss it launches the same OIDC browser flow setup would have run, while a cached or refreshable token is still printed without prompting. This is what signs the user in on first use after a lazy setup, with no extra command to run. Regenerate CLI docs for the new flag and updated token help. Co-Authored-By: Claude Opus 4.8 (1M context) * Widen LLM proxy per-request token-fetch timeout The proxy's per-request token fetch used a 10-second timeout. After a lazy setup, the first request through the proxy drives the interactive OIDC browser login via the token source, and 10 seconds is far too short for a human to complete it — the request would be cut off mid-login. Introduce a tokenFetchTimeout constant set to 3 minutes. Once a token is cached, subsequent requests are served from cache and return well within the bound, so only the initial login ever approaches it. Co-Authored-By: Claude Opus 4.8 (1M context) * Add e2e coverage for lazy setup and deferred login Cover the lazy provisioning flow end to end: "thv llm setup --lazy" completes with no browser and patches tool config identically to a normal setup, and the first "thv llm token" afterwards launches the deferred OIDC browser flow and prints a fresh token. Generalize runSetupWithOIDCCompletion into runWithOIDCCompletion so any command that performs the browser flow can be driven to completion in tests. Update the expired-cached-token test to drive that completion: "thv llm token" is now interactive, so an expired token with no refresh token falls through to the browser flow rather than failing fast.

Reword to "signed in on the first request a configured tool makes to the LLM gateway" so the message accurately describes when (and that) login happens. Addresses review feedback on #5427.

That module is deprecated as of Docker v29 (moby split it into github.com/moby/moby/{client,api}), and the docker-v29.x tags cannot be consumed via `go get`, so there is no newer module version to update to. ToolHive's production code already imports moby/moby/{client,api}; docker/docker lingered only as a test-only indirect dependency of testcontainers-go. testcontainers-go v0.42.0 migrated off docker/docker onto moby/moby/{client,api}. Bumping from v0.40.0 and running `go mod tidy` removes docker/docker (and the now-orphaned morikuni/aec) from the module graph entirely, clearing the finding at its source. No source changes are required; the authserver/storage integration tests pass.

2001 From: Jakub Hrozek Date: Wed, 3 Jun 2026 21:57:50 +0100 Subject: [PATCH 259/291] Thread VirtualMCPServer name into Cedar authz middleware (#5448) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Cedar authorization policies compiled by the operator reference the actual VirtualMCPServer name as the resource entity (e.g. MCP::"my-vmcp"). The factory hard-coded the string "vmcp" when calling authz.CreateMiddlewareFromConfig, so the resource entity never matched and Cedar's default-deny fired on every request — 403 for all principals regardless of policy. Fix by adding a serverName parameter to NewIncomingAuthMiddleware and newCedarAuthzMiddleware, and passing vmcpCfg.Name at the serve.go call site. Adds a regression test that scopes a Cedar permit policy to a specific resource name and asserts it is honoured.

This is the domain boundary that New(cfg) -> VMCP and the decorators will consume; no implementation yet. Implements issue #5434: - Add pkg/vmcp/core with the VMCP interface (ListTools/CallTool/List+ Read/List+GetPrompt/Lookup{Tool,Resource,Prompt}/Close), identity an explicit *auth.Identity on every data method, never read from context. - Encode the full behavioral contract in the interface doc comment (anonymous nil identity, decorators subtract-only, read-only args/meta, nil ResourceReadResult.Meta). - Declare Config with typed collaborator fields; no construction logic. - No mcp-go types cross the boundary (anti-pattern #5). The core lives in pkg/vmcp/core rather than root pkg/vmcp because Config references aggregator/router/composer/health/authz, all of which import pkg/vmcp; a root-package Config would create an import cycle.

from fork MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Add NAT64 prefixes to IsPrivateIP SSRF guard The hand-rolled private/reserved IP guard in pkg/networking/utilities.go did not recognise the IPv6 NAT64 translation prefixes 64:ff9b::/96 (RFC 6052) and 64:ff9b:1::/48 (RFC 8215). A NAT64 address such as 64:ff9b:1::a9fe:a9fe is the encoding of 169.254.169.254 (the cloud metadata endpoint) but is a syntactically global-unicast IPv6 address, so IsPrivateIP returned false and the connection was allowed. Behind a NAT64/DNS64 gateway this enabled SSRF to internal and link-local services (including IMDS) via the CIMD authorization-server fetch path and the webhook/remote HTTP client. IsPrivateIP now detects NAT64-prefixed addresses, extracts the embedded IPv4 (low 32 bits), and re-evaluates it with the existing IPv4 private/reserved checks. NAT64 addresses that embed a genuinely public IPv4 remain allowed, so legitimate NAT64 egress is not over-blocked. * Harden NAT64 /48 decoding and add SSRF tests The initial fix always read the embedded IPv4 from the low 32 bits. That is correct for the well-known 64:ff9b::/96 and the 64:ff9b:1::/96 sub-prefix, but the RFC 8215 local-use range is a /48 that operators may subdivide with a shorter NAT64 prefix, placing the embedded IPv4 outside the low 32 bits. Decoding the low 32 bits there could read attacker-chosen suffix bytes and misclassify an internal target as public — a false-negative SSRF bypass. Limit low-32-bit decoding to the two /96 prefixes and block the remainder of 64:ff9b:1::/48 wholesale, so undecodable NAT64 addresses fail closed. Add NAT64 coverage (private and public embeddings, plus the non-/96 local-use case) to TestIsPrivateIP and TestAddressReferencesPrivateIp, which the initial change asserted but did not commit. Behavior change: addresses in 64:ff9b:1::/48 but outside 64:ff9b:1::/96 are now classified as private even when their low 32 bits embed a public IPv4. This affects only deployments that use a non-/96 NAT64 prefix carved from the RFC 8215 local-use range to reach public IPv4 hosts (a rare configuration); the well-known 64:ff9b::/96 and the local-use 64:ff9b:1::/96 decode normally and are unaffected. The over-block is intentional (fail closed): the embedded IPv4 cannot be located for non-/96 prefixes, so the range is rejected rather than risk a bypass. Co-Authored-By: Claude Opus 4.8 (1M context) * Block unspecified and reserved IPv4 ranges While hardening the SSRF guard, classify special-use ranges that IsPrivateIP did not previously treat as private: - 0.0.0.0/8 (RFC 1122 "this host") and the unspecified address (0.0.0.0 / ::) — on Linux a dial to 0.0.0.0 is delivered to loopback, so it behaves like a loopback target; - 240.0.0.0/4 (RFC 1112 reserved / Class E), which also covers the 255.255.255.255 limited-broadcast address. Add 0.0.0.0/8 and 240.0.0.0/4 to privateIPBlocks and an IsUnspecified() check to IsPrivateIP, with table-driven coverage. Defense-in-depth (no known exploited path); it composes with the existing NAT64 decoding so a NAT64 address embedding 0.0.0.0 is also rejected.

This confines all mcp-go translation to the sanctioned adapter (server/sdk_elicitation_adapter.go), closing anti-pattern #5 on the elicitation path ahead of New(cfg) -> VMCP (#5437). Implements changes for issue #5436: - Add pkg/vmcp/elicitation.go with the domain interface and value types (form-mode only; no URL-mode fields) - Retype DefaultElicitationHandler to the domain requester; security validation and the Content any->map assertion are unchanged - Make sdkElicitationAdapter the sole domain <-> mcp-go translator, with an internal SDK seam so translation is unit-testable; copy Meta before NewMetaFromMap mutates it and omit _meta when nil - Regenerate mocks under pkg/vmcp/mocks; drop composer/mocks * Strengthen elicitation handler timeout and content tests Addresses stacklok/toolhive#5456 review comments: - MEDIUM elicitation_handler_test.go (3357216826): add accept case with non-map Content asserting it is treated as nil, covering the warn-log else branch the #5436 Testing Strategy requires - MEDIUM elicitation_handler_test.go (3357216877): replace the weak timeout_capped_to_max table case with a dedicated test that captures the context deadline and asserts it is capped to maxElicitationTimeout, so the timeout-bomb protection is actually guarded --- pkg/vmcp/composer/elicitation_handler.go | 64 +++--- pkg/vmcp/composer/elicitation_handler_test.go | 118 ++++++----- .../composer/elicitation_integration_test.go | 59 +++--- .../mocks/mock_sdk_elicitation_requester.go | 57 ------ pkg/vmcp/elicitation.go | 57 ++++++ pkg/vmcp/mocks/mock_elicitation_requester.go | 57 ++++++ pkg/vmcp/server/sdk_elicitation_adapter.go | 79 +++++--- .../server/sdk_elicitation_adapter_test.go | 184 ++++++++++++------ 8 files changed, 413 insertions(+), 262 deletions(-) delete mode 100644 pkg/vmcp/composer/mocks/mock_sdk_elicitation_requester.go create mode 100644 pkg/vmcp/elicitation.go create mode 100644 pkg/vmcp/mocks/mock_elicitation_requester.go diff --git a/pkg/vmcp/composer/elicitation_handler.go b/pkg/vmcp/composer/elicitation_handler.go index 156283318c..786a538412 100644 --- a/pkg/vmcp/composer/elicitation_handler.go +++ b/pkg/vmcp/composer/elicitation_handler.go @@ -4,8 +4,6 @@ // Package composer provides composite tool workflow execution for Virtual MCP Server. package composer -//go:generate mockgen -destination=mocks/mock_sdk_elicitation_requester.go -package=mocks github.com/stacklok/toolhive/pkg/vmcp/composer SDKElicitationRequester - import ( "context" "encoding/json" @@ -14,7 +12,7 @@ import ( "log/slog" "time" - "github.com/mark3labs/mcp-go/mcp" + "github.com/stacklok/toolhive/pkg/vmcp" ) const ( @@ -69,20 +67,6 @@ var ( ErrContentTooLarge = errors.New("response content too large") ) -// SDKElicitationRequester is an abstraction for the underlying MCP SDK's elicitation functionality. -// -// This interface wraps the SDK's RequestElicitation method, enabling: -// - Migration from mark3labs SDK to official SDK without changing workflow code -// - Mocking for unit tests -// - Custom implementations for testing -// -// The SDK handles JSON-RPC ID correlation internally - our wrapper doesn't need to track IDs. -type SDKElicitationRequester interface { - // RequestElicitation sends an elicitation request via the SDK and blocks for response. - // This wraps the SDK's synchronous RequestElicitation method. - RequestElicitation(ctx context.Context, request mcp.ElicitationRequest) (*mcp.ElicitationResult, error) -} - // DefaultElicitationHandler implements ElicitationProtocolHandler as a thin wrapper around the MCP SDK. // // This handler provides: @@ -98,19 +82,20 @@ type SDKElicitationRequester interface { // // Thread-safety: Safe for concurrent calls.

Implements #5437: - All ten VMCP methods on *coreVMCP. The core is stateless w.r.t. sessions: List/Lookup/Call health-filter the registry and aggregate on demand, then route through a per-call SessionRouter bound to the fresh routing table (removing context-injected capability coupling). "The core filters, Serve caches." - Injected health.StatusProvider drives filterHealthyBackends before aggregation, preserving today's exact include/exclude rules (copied from discovery/middleware.go; temporary C2 duplication until Phase 3). - Composite tools are advertised in ListTools (decorators may only subtract) and executed in CallTool via the relocated per-session composer pattern. - Close() stops the state store cleanup goroutine and is idempotent. - Relocate the backend-client telemetry decorator to pkg/vmcp/internal/backendtelemetry so server and core share it without an import cycle; server.New behavior is unchanged. Identity is an explicit *auth.Identity on every method, never read from context and never logged. The Cedar admission seam (#5438) is not wired here. Co-Authored-By: Claude Opus 4.8 (1M context) * Address code review feedback Fixed issues from code review: - HIGH: ReadResource/GetPrompt now pass the advertised name straight to the backend client (which owns the single name translation), matching CallTool and removing the fragile reliance on idempotent re-translation - MEDIUM: add TestCallTool_ResolvesRenamedTool (dot-convention/prefixed name resolution) and table-driven TestExecuteComposite covering the error/timeout/nil-result/result.Error branches - MEDIUM: clarify that core aggregation is intentionally uncached (Serve caches) and that validateWorkflowDefs returns nil-when-empty by design Co-Authored-By: Claude Opus 4.8 (1M context) * Gate composite execution on the ListTools conflict check CallTool's composite branch only applied the accessibility filter, so on a composite/backend tool-name collision it executed the withheld composite while ListTools advertised the backend tool (advertise-vs-execute divergence). Extract a shared accessibleComposites helper used by both advertisedTools and CallTool: on a conflict all composites are dropped and the name falls through to backend routing, so advertised == executed, matching the legacy decorator.

Add defense in depth: - composer.DefaultElicitationHandler.RequestElicitation returns the new ErrElicitationNotConfigured instead of dereferencing a nil requester, so every caller fails cleanly. - core.New rejects construction when Elicitation is nil and any workflow contains an elicitation step (directly or as a forEach inner step), surfacing the misconfiguration at startup per the documented contract.

helm-unittest suite for operator-crds toggles The operator-crds chart wraps every CRD in two values gates: crds.install (gates the whole render) and crds.keep (gates the helm.sh/resource-policy: keep annotation). A regression in either is silent — `helm install` still succeeds with the install gate removed, and a dropped keep annotation silently cascade-deletes CRs on uninstall. `ct install` cannot catch these. Add a helm-unittest suite covering all 13 CRDs that asserts the default render, crds.install=false, and crds.keep=false behaviours, plus a `task helm-unittest` runner and a CI step. Following the pattern established in stacklok-llm-gateway. Co-Authored-By: Claude Opus 4.8 (1M context) * Generalize helm-unittest CI step description The suite will grow beyond the operator-crds toggles, so replace the toggle-specific comment with a generic note on what helm-unittest is and why we run it.

Re-platform that single Cedar decision into the core so List* (filter) and Call/Read/Get (deny) enforce it from one source. Implements issue #5438: - Add the Admission seam (interface + Cedar-backed adapter) in pkg/vmcp/core/admission.go. The core moved to its own package in #5437; the adapter wraps pkg/authz, which would cycle with the root vmcp package, so the seam lives here rather than pkg/vmcp/admission.go. - Build the authorizer from cfg.Authz via the same factory path the HTTP middleware uses (authorizers.GetFactory + CreateAuthorizer); no new policy language. A nil cfg.Authz yields an allow-all seam, matching the AuthzMiddleware != nil guard. - Re-inject the explicit identity and core-sourced Tool.Annotations into the ctx the authorizer reads, replacing AnnotationEnrichmentMiddleware on the domain path. - Keep optimizer meta-tools (find_tool/call_tool) exempt via cfg.PassThroughTools, mirroring the HTTP response filter. - Add cfg.ServerName/cfg.PassThroughTools to feed the seam. server.New is untouched: the live path still enforces via middleware in Phase 1, so double-enforcement only ever occurs in tests that exercise the core directly. #5441 removes the HTTP middleware. Co-Authored-By: Claude Opus 4.8 (1M context) * Address code review feedback Fixed issues from code review: - HIGH: newAdmission now rejects an empty ServerName when Authz is set, mirroring the live factory's fail-loud check (incoming.go:120) so a misconfigured composition root fails at New instead of silently changing Cedar resource-scoped policy semantics. - HIGH: corrected the AllowToolCall comment — the seam exempts the optimizer meta-tool name only; replicating the HTTP middleware's call_tool inner-tool authorization is documented as a #5441 call-path wiring requirement, not this seam's responsibility. - MEDIUM: sharpened the convertAnnotations comment to state the precise server->core import cycle that forces the (temporary, C2-style) duplication, and documented that EntitiesJSON normalization belongs to the authz.Config builder, not the generic factory path. - MEDIUM: added TestAdmission_AnnotationGatedDecisionMatchesListAndCall proving readOnlyHint-gated decisions match between ListTools and CallTool through the core; documented CallTool's no-hint fallback. Co-Authored-By: Claude Opus 4.8 (1M context) * Clarify admission seam parity comments Second-pass review follow-ups (all non-blocking MEDIUM): - Clarify that FilterTools' non-nil empty slice mirrors pkg/authz filterToolsByPolicy and that nil-vs-[] wire normalization is the Serve layer's concern — the allow-all seam returns input unchanged by design (byte-for-byte parity with the nil-authorizer no-op), not an oversight. - Name newCedarAuthzMiddleware as the sibling construction path that must stay in lockstep until #5441 collapses them into one shared constructor. Co-Authored-By: Claude Opus 4.8 (1M context) * Extract config validation to keep New under complexity limit Rebasing onto main combined the admission-seam build in New with #5437's workflowsRequireElicitation check (added during that PR's review), pushing New's cyclomatic complexity to 16 (gocyclo limit 15). Move the input-validation guards into a validateConfig helper to bring New back under the limit; behavior is unchanged. Co-Authored-By: Claude Opus 4.8 (1M context) * Address admission seam PR review feedback Addresses stacklok/toolhive#5459 review comments: - MEDIUM core_calls.go (3374390455): classify the authorizer-error branch of Call/Read/Get as ErrAuthorizationFailed (fail closed), mirroring the live authorizeAndServe; preserve the underlying error in the chain for diagnostics. - MEDIUM admission_test.go (3374390466): log through an injectable *slog.Logger (withLogger option) and capture via a buffer-backed logger instead of swapping the global slog default, removing the -race hazard vs parallel siblings. - MEDIUM admission_test.go (3374390470): capture call args in mockCall and assert they reach the authorizer; add a Cedar arg-gated end-to-end test through CallTool. - LOW admission.go (3374390475): add the nil-guard to the server convertAnnotations copy so the "keep in sync" claim is truthful (both retired in #5441). - LOW admission.go (3374390484): document the deliberate fail-closed divergence for a non-nil-but-empty-policies config vs the live allow-all. - LOW core_calls.go (3374390492): add a direct findAdvertisedTool table test and an end-to-end nil-branch CallTool test; correct the inaccurate "unroutable" comment. - LOW admission.go (3374390498, 3374390532): cite handleToolsCall and the EntitiesJSON default by symbol instead of drift-prone file:line. - LOW admission.go (3374390547): wrap CreateAuthorizer failures with ErrInvalidConfig for uniform classification with the sibling construction errors. - LOW core.go (3374390556): document ServerName as a required precondition when Authz is set (and ignored when nil). Co-Authored-By: Claude Opus 4.8 (1M context) * Remove PassThroughTools optimizer carve-out from admission seam Addresses stacklok/toolhive#5459 review (r3377688855, blocker): the PassThroughTools field carved an optimizer-specific hole into the generic admission seam but covered only list-time visibility — not call_tool inner-target authorization, find_tool response filtering, or inner-target annotation sourcing. Shipping that partial commitment would lock in "the seam knows about meta-tools" as the implicit answer without scoping the full optimizer-admission work. Make the seam optimizer-agnostic instead: drop PassThroughTools from Config, cedarAdmission, newAdmission, and delete TestCedarAdmission_PassThroughExempt. The full optimizer-admission integration is deferred to its own focused PR; until then #5441's composition root fails fast (ErrInvalidConfig) on (Authz + optimizer) so the combination never routes through this seam, and the optimizer keeps the HTTP middleware.

The route mux and HTTP lifecycle are provided by the carried-forward Handler/Start/Stop, so observable behavior is unchanged and server.New is not yet routed through Serve. Implements changes for issue #5439: - Add ServerConfig (transport-only fields plus the cross-cutting TelemetryProvider/AuditConfig) and Serve in pkg/vmcp/server/serve.go - Validate nil cfg / nil core / nil SessionFactory via ErrInvalidConfig - Wire the core's idempotent Close into the server shutdown sequence - Guard the /status handler against a nil backend registry, which the transport does not own yet in this phase Co-Authored-By: Claude Opus 4.8 (1M context) * Address Serve skeleton review feedback - Clarify the Serve doc comment: it builds only the mcp-go server and shutdown wiring; the route mux and HTTP lifecycle stay in the carried-forward Handler/Start until later phases relocate them - Document the Config fields buildServeConfig deliberately leaves unmapped (AuthzMiddleware, HealthMonitorConfig) and why - Add a reflection drift guard asserting every other Config field is populated by buildServeConfig, so a future field can't be dropped silently Co-Authored-By: Claude Opus 4.8 (1M context) * Tighten Serve skeleton per PR review Addresses stacklok/toolhive#5467 review comments: - MEDIUM serve.go (3381738359): extract shared default consts (defaultServerName/Version/Host/EndpointPath) referenced by New and buildServeConfig, and assert against them in tests, killing the triplicated literals - MEDIUM serve.go (3381738361): drop the dead Config.StatusReporter mapping (set directly on Server like HealthMonitor) and add it to the drift guard's intentionallyUnmapped set - LOW-MEDIUM serve.go (3381738364): document the returned *Server's nil-field contract (must not be Started/served on "/" until later phases wire session/discovery/registry) - MEDIUM serve_test.go (3381738372): probe /.well-known/ for the clean JSON 404; soften the overstated "auth-chain absent" comment - MEDIUM serve_test.go (3381738374): note the drift guard checks presence only; cover SessionTTL/StatusReportingInterval value correctness in TestServePreservesExplicitConfig - LOW status.go (3381738382): slog.Debug in the nil-registry branch so an unexpectedly-nil registry on the New path is observable Also from the review body: add a positive /metrics-registered test and a combined nil-cfg+nil-vmcp validation case.

The operator-crds chart already has a suite from #5468; the operator chart did not. Add a default-install suite that renders the chart with no value overrides and asserts the expected output for every resource it creates (Deployment, ServiceAccount, ClusterRole, ClusterRoleBinding, and the leader-election Role/RoleBinding), plus that the HPA is absent. Image fields use matchRegex on the repo path so version bumps don't break the suite. Wire the operator chart into the `helm-unittest` task and ignore tests/ when packaging the chart.

Signal the deprecation so users migrate before it is removed, while keeping the CRD fully functional. - Mark the live v1beta1 MCPRegistry with deprecatedversion:warning so kubectl warns on every interaction; repoint the stale v1alpha1 warning (previously "use v1beta1") at the Helm chart. - Emit a Warning event plus log line from the reconciler, once per spec change, steering users to the chart. Wire an EventRecorder into the reconciler, mirroring the other operator controllers. - Express the deprecation as prose, not the Go "Deprecated:" convention, so staticcheck SA1019 does not flag the operator's own internal uses. Co-Authored-By: Claude Opus 4.8 (1M context) * Regenerate MCPRegistry CRD manifests and docs Pick up the MCPRegistry deprecation markers and doc comments via operator-manifests and crdref-gen.

Today serviceaccount.yaml names the SA from fullname and clusterrole/rolebinding.yaml hardcodes the subject, so two of the four assertions fail. This commit captures the bug as a red test; the template fix follows. Co-Authored-By: Claude Opus 4.8 (1M context) * Route SA references through serviceAccountName helper serviceaccount.yaml named the ServiceAccount from fullname, while clusterrole/rolebinding.yaml hardcoded the subject and leader-election-role.yaml used the raw serviceAccount.name. Overriding operator.serviceAccount.name made these diverge: verified in a kind cluster, the operator Deployment got zero pods ("error looking up service account my-sa: serviceaccount not found"). Route all four references through the existing toolhive-operator.serviceAccountName helper (use $ inside the rolebinding range). This is a no-op on default values, where every reference already resolves to toolhive-operator. Extend the custom-naming suite with the empty-name fallback cases so the generated-name path is locked in too.

09:17:09 -0400 Subject: [PATCH 280/291] Renew public client TTL on successful token exchange (#5469) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Renew public client TTL on read in Redis store Public clients registered via DCR get DefaultPublicClientTTL stamped on their Redis registration at registration time, and GetClient only reads it back. The TTL is therefore a fixed window from registration: an actively-used public client (e.g. a long-lived MCP desktop/IDE client that caches its client_id) is evicted DefaultPublicClientTTL after it registered, regardless of use. Its next token request then fails at the token endpoint with invalid_client, and the only recovery is to fully re-register the client. Renew the TTL to DefaultPublicClientTTL on a successful GetClient for public clients, turning expiry into a sliding window of inactivity. Abandoned clients still expire after the window, preserving the anti-bloat intent of RegisterClient; confidential clients have no TTL and are left untouched. Renewal is best-effort: a failure is logged and does not fail the lookup. The in-memory backend stores clients without a TTL, so it is unaffected. Add a unit test covering both the public-client renewal and the confidential-client no-TTL invariant. Signed-off-by: Mani Japra * Renew client TTL on token success, not on read Review flagged that renewing the public-client TTL inside GetClient fires on the unauthenticated front-channel GET /oauth/authorize read (fosite's NewAuthorizeRequest), not only on the token endpoint. Public clients have no secret, so any caller who knows a public client_id could keep its registration alive indefinitely by polling authorize, defeating the anti-bloat TTL the renewal was meant to preserve. Move renewal to the proven-use signal: a successful token exchange or refresh. Add RenewClientTTL to the ClientRegistry interface — Redis EXPIREs the public client's key (confidential clients and missing keys are left untouched), the in-memory backend is a documented no-op — and call it best-effort from TokenHandler after NewAccessResponse succeeds. GetClient returns to a pure read. Regenerate storage mocks for the new method. Update tests to exercise RenewClientTTL directly and assert that a successful token exchange renews the public client's TTL.

Wed, 10 Jun 2026 18:12:31 +0400 Subject: [PATCH 282/291] Prevent path traversal in LocalStore.getFilePath (#5464) getFilePath constructed file paths with filepath.Join but never verified the result stayed within basePath. A name like "../../../etc/passwd" would resolve outside the state directory, making GetReader, GetWriter, CreateExclusive, Delete, and Exists all vulnerable to path traversal. Fix: after filepath.Join (which calls filepath.Clean to resolve ".." components), check that the result starts with basePath+separator using the same containment pattern already established in pkg/fileutils/contained.go. Update the #nosec G304 comments to reflect that the check is now actually enforced.

Implements changes for issue #5440: - Register OnRegisterSession + OnBeforeListTools/OnBeforeCallTool hooks in Serve, delegating to the unchanged *Server receiver methods - Build the transport session manager, session data storage (memory/Redis, THV_SESSION_REDIS_PASSWORD) with a close-on-error leak guard, and the vMCP session manager inside Serve - Add ServerConfig.SessionManagerConfig (pre-built *sessionmanager.FactoryConfig) and the shared BackendRegistry; fold the now-redundant SessionFactory/ OptimizerFactory/OptimizerConfig slots into FactoryConfig - Add Serve-level tests driving the relocated hooks + two-phase creation via the SDK lifecycle, plus buildSessionDataStorage coverage; the HTTP suite stays on server.New as its parity gate Co-Authored-By: Claude Opus 4.8 (1M context) * Address code review feedback Fixed issues from code review: - HIGH: Split the t.Setenv redis case into its own non-parallel test and made TestBuildSessionDataStorage parallel, resolving the tparallel lint failure - MEDIUM: Validate BackendRegistry in Serve (fail loudly with ErrInvalidConfig instead of nil-panicking inside the OnRegisterSession hook); add a nil-registry validation case and a testMinimalServeConfig helper - MEDIUM: Document on SessionManagerConfig that the composition root must validate workflow definitions before assembling FactoryConfig, since Serve no longer runs validateWorkflows Co-Authored-By: Claude Opus 4.8 (1M context) * Fix Serve session-manager leak and tighten Serve tests Addresses stacklok/toolhive#5471 review comments: - LOW serve.go (3383233591): build the transport sessionManager after the fallible buildSessionDataStorage/sessionmanager.New calls so its cleanup goroutine cannot leak on a Serve error path (symmetry with the storage guard) - MEDIUM serve_session_test.go (3383233579): add a Serve-level test covering the cross-pod empty-store inject branch of lazyInjectSessionTools (and the pod-local no-op branch), the path the prior tests did not reach - LOW serve_session_test.go (3383233598): remove dead mu/lastSession test state - LOW serve_session_test.go (3383233608): rename the storage-error test to match what it asserts (error returned when session manager construction fails) - LOW serve_session_test.go (3383233616): bind the redis test assertion to the connection-failure wrap so an unrelated error can't satisfy it Co-Authored-By: Claude Opus 4.8 (1M context) --------- Co-authored-by: Claude Opus 4.8 (1M context) --- pkg/vmcp/server/serve.go | 188 ++++++++++---- pkg/vmcp/server/serve_session_test.go | 355 ++++++++++++++++++++++++++ pkg/vmcp/server/serve_test.go | 68 +++-- 3 files changed, 542 insertions(+), 69 deletions(-) create mode 100644 pkg/vmcp/server/serve_session_test.go diff --git a/pkg/vmcp/server/serve.go b/pkg/vmcp/server/serve.go index 4d6546e566..d5080b2c88 100644 --- a/pkg/vmcp/server/serve.go +++ b/pkg/vmcp/server/serve.go @@ -10,17 +10,18 @@ import ( "net/http" "time" + "github.com/mark3labs/mcp-go/mcp" "github.com/mark3labs/mcp-go/server" "github.com/stacklok/toolhive/pkg/audit" asrunner "github.com/stacklok/toolhive/pkg/authserver/runner" "github.com/stacklok/toolhive/pkg/telemetry" + transportsession "github.com/stacklok/toolhive/pkg/transport/session" "github.com/stacklok/toolhive/pkg/vmcp" vmcpconfig "github.com/stacklok/toolhive/pkg/vmcp/config" "github.com/stacklok/toolhive/pkg/vmcp/core" "github.com/stacklok/toolhive/pkg/vmcp/health" - "github.com/stacklok/toolhive/pkg/vmcp/optimizer" - vmcpsession "github.com/stacklok/toolhive/pkg/vmcp/session" + "github.com/stacklok/toolhive/pkg/vmcp/server/sessionmanager" vmcpstatus "github.com/stacklok/toolhive/pkg/vmcp/status" ) @@ -29,8 +30,14 @@ import ( // It carries the subset of the legacy server.Config that configures the HTTP/SDK // runtime, plus the cross-cutting TelemetryProvider/AuditConfig that are consumed // by both the core (core.New) and the transport (Serve) — not a clean partition. -// The fields the core owns (Aggregator, Router, BackendRegistry, BackendClient, -// WorkflowDefs, Authz) live on core.Config instead and are absent here. +// The fields the core exclusively owns (Aggregator, Router, BackendClient, Authz) +// live on core.Config instead and are absent here.

reyortiz3 Date: Wed, 10 Jun 2026 13:06:13 -0400 Subject: [PATCH 285/291] Address Redis Cluster mode review follow-ups for #5153 (#5210) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Address Redis Cluster mode review follow-ups Three small follow-ups from the PR #5153 review that were deferred so the core cluster-mode support could land: - Document the cluster slot invariant for storeUpstreamTokensScript. The script reads oldUserID from KEYS[1] inside its body to keep the user-set bookkeeping atomic, so the user-set keys are constructed dynamically from ARGV[4] rather than declared as KEYS. The new comment makes the {ns:name} hash-tag requirement explicit, so a future refactor that rebuilds the prefix without the tag will be caught in review rather than silently regressing on standalone Redis and exploding with CROSSSLOT on a real cluster. - Filter SMEMBERS results in GetAllUpstreamTokens, DeleteUpstreamTokens, and GetLatestUpstreamTokensForUser to entries that share the storage instance's keyPrefix, warn-logging anything dropped. A stray un-prefixed member (legacy data, an external admin op, a test fixture) would today surface as CROSSSLOT under cluster while passing on standalone; this turns it into a logged warning. The defensive filter is a pure helper with table-driven tests, plus a behavior test that captures slog output to prove the wiring at all three call sites. - Align the operator CRD `tls` doc with the storage-layer comment so that crd-api.md and `kubectl explain` both describe TLS as applying to "Redis/Valkey master or cluster nodes" — previously cluster-mode users reading the CRD field would not realise this same field configured TLS for cluster-node connections. Regenerated CRD YAML, Helm templates, and crd-api.md to match.

Both are repeatable and were being done by hand each time. This adds a workflow that fires on the `release: published` event (the same event that already drives releaser.yml) and: - Runs the existing `release-notes` Claude skill to analyze every merged PR in the range, cross-reference issues, and dispatch expert subagents for breaking-change assessment, producing copy-pasteable markdown. - Delivers it review-then-publish: the public release notes are not overwritten. The markdown is uploaded as an artifact, written to the job summary, and posted as a comment on the release PR for a maintainer to review and apply. - Posts a single Slack announcement reusing the theme summary the skill already emits, plus a link to the full release notes, via the same incoming-webhook pattern as the existing failure notification. Also supports workflow_dispatch with a tag input for dry-running against an already-published release.

This unauthenticated fallback is intentional, but it was silent: the only signal was a debug log, and the README claimed unconditional "identity enforcement per request" (GHSA-hfrv-94x5-85p2). Make the state visible without changing the default behavior: - Raise the no-auth fallback log in GetAuthenticationMiddleware from Debug to Warn, naming the consequence and how to enable auth. - Document the unauthenticated default on the OIDCConfigRef field of both MCPServer and MCPRemoteProxy; regenerate the CRD API reference. - Reword the README so identity enforcement is stated as conditional on configuring an authentication source. Co-Authored-By: Claude Opus 4.8 (1M context) * Correct crdref-gen working directory in operator rule The rule said to run `task crdref-gen` from `cmd/thv-operator/`, but the task resolves its config path relative to the repo root and fails from that directory. Document the correct invocation. Co-Authored-By: Claude Opus 4.8 (1M context) * Regenerate operator CRD manifests Propagate the OIDCConfigRef security note into the generated CRD YAML descriptions for MCPServer and MCPRemoteProxy.

ToolHive includes a Kubernetes operator, so you can declare policies, integrate with your IdP and observability stack, emit OTel traces, and more … all with familiar tools and patterns. Most MCP solutions are SaaS, but your compliance requirements prohibit sensitive info from being processed by SaaS providers.

ToolHive is the exception that allows you to self-host your MCP registry, gateway, etc. You can pilot the entire platform, and when you’re ready to scale, Stacklok’s got the added capabilities and expert team ready! diff --git a/cmd/thv-operator/api/v1beta1/mcpremoteproxy_types.go b/cmd/thv-operator/api/v1beta1/mcpremoteproxy_types.go index 9cf36c0de6..17a8df3599 100644 --- a/cmd/thv-operator/api/v1beta1/mcpremoteproxy_types.go +++ b/cmd/thv-operator/api/v1beta1/mcpremoteproxy_types.go @@ -57,6 +57,12 @@ type MCPRemoteProxySpec struct { // The referenced MCPOIDCConfig must exist in the same namespace as this MCPRemoteProxy. // Per-server overrides (audience, scopes) are specified here; shared provider config // lives in the MCPOIDCConfig resource. + // + // SECURITY: if this field is omitted and no other authentication source is configured, + // the proxy runs UNAUTHENTICATED.
