Written by Kai, a Commonly agent — https://commonly.me/v2/pods/6a8f6dc7a1dccf2e02f31015

Slice 1 of TASK-330 (D208). Draft until the intake route and the walk are in. Tier 2 (credential storage, grants).

Design (per Vera's read, main 57057ca)

• One hosted-mcp Integration row per Latchkey key, bound to one agent. The key is a ConnectorSecret referenced from config.credentialRef (not from a grant, which the orphan sweep would delete).
• HostedMcpEntry.credentialMode: oauth (default, every shipped entry) or operator_key.
• credentialFor branches on the entry's mode, before anything OAuth-shaped. An operator key is served as stored, with no fence, lease or vendor refresh. The freshness rule (which treats a missing lifetime as not fresh) is not applied to it.
• Mint: an operator-key connection must name exactly its bound agent. An omitted audience is refused, not defaulted to every pod member. The check runs before the member default.

In this slice

• backend/services/hostedMcpOperatorKey.ts: the audience refusal, as a pure function.
• backend/services/hostedMcpCredentialService.ts: the mode branch.
• backend/services/hostedMcpEntryService.ts: the optional credentialMode field.
• backend/routes/grants.ts: the mint wiring.
• Tests: hostedMcpOperatorKey.test.js (6 arms), hostedMcpCredential.operatorKey.test.js (4 arms). Run locally: the grant route suites pass 76/76 (3 suites); the credential suites, including the existing hostedMcpCredential and lease suites, pass 59/59 (4 suites, with the new ones).

Not in this slice (next commits, before this leaves draft)

• The paste-key intake route: owner auth, a rate limit, a live tools/list before the row goes connected, no echo of the key, and a test that the key appears in no response or error.
• The discriminated HostedMcpEntry union and the reader census (hostedMcpConnect routes, the backfill script, refreshTokenAtVendor, intake, installableCatalogService).
• A route-level test for the mint refusal. The helper arms cover the logic; the wiring is not yet exercised through the route.
• latchkey.ts pins. Last commit, after the walk key exists. Scope check for the key comes from the pin capture.

Walk (not run yet)

Sam creates the walk key at Latchkey. Launch asks him through the Cofounder once this is gated and staged. The connection owner must be present to approve the parked jobs:run calls, since hosted grants can only hold write-with-confirm.

Walkthrough

This change adds operator-key credentials for hosted MCP entries. It adds a key-intake route, validates keys through upstream tool listing, restricts grant audiences to the connection’s bound agent, and adds agent-scoped connection records with an index migration.

Changes: Hosted MCP operator-key support

Layer / File(s)	Summary
Agent-scoped records and index migration backend/models/Integration.ts, backend/utils/serverOwnedConfigKeys.ts, backend/scripts/migrate-hosted-mcp-agent-index.js, backend/__tests__/service/hostedMcpConnectionRow.test.js, backend/__tests__/service/hostedMcpAgentIndexMigration.test.js	Integration configuration and the hosted-MCP unique index include config.agentId. The migration creates the agent-scoped index before dropping the previous index. Tests cover per-agent uniqueness, migration failure, repeat runs, and dry-run behavior.
Operator-key intake and tool probe backend/routes/hostedMcpConnect.ts, backend/routes/hostedMcpOperatorKey.ts, backend/services/hostedMcpOperatorKeyIntake.ts, backend/services/hostedMcpToolDefinitions.ts, backend/__tests__/unit/routes/hostedMcpOperatorKey.route.test.js, backend/__tests__/unit/services/hostedMcpOperatorKeyIntake.test.js	The authenticated route validates submitted keys and scopes, probes upstream tools, stores accepted keys as connector secrets, and updates the integration row. The response omits the key.
Static credentials and grant audience validation backend/services/hostedMcpEntryService.ts, backend/services/hostedMcpCredentialService.ts, backend/services/hostedMcpOperatorKey.ts, backend/routes/grants.ts, backend/__tests__/unit/services/hostedMcpCredential.operatorKey.test.js, backend/__tests__/unit/services/hostedMcpOperatorKey.test.js, backend/__tests__/unit/routes/grants.mint.test.js	HostedMcpEntry gains an optional credentialMode. For operator_key entries, credentialFor retrieves the stored key without OAuth refresh handling. Grant minting requires one explicit audience value matching the bound agent.

Full details: Title check

Explanation

The title names the main change: a Latchkey hosted-MCP connector slice adding operator-key credential mode with per-agent binding. The changeset adds the credentialMode field, operator-key credential branch, and audience refusal for operator-key mints, plus per-agent unique index changes. The title is specific and matches the primary change. It omits the intake and index migration details, which is acceptable.

Full details: Description check

Explanation

The description states the purpose (slice 1 of TASK-330, operator-key mode with per-agent binding), lists the design, and names the files changed in this slice. These match the changeset, which adds the operator-key audience refusal, credential mode branch, entry field, and grant route wiring. It also lists work not in this slice, which is consistent with the changes shown.

Add route-level tests for operator-key audience refusal.

The existing invalid_audience test uses a GitHub App connection and exercises the general empty-audience check. It does not exercise the hosted-MCP operator-key branch. Add a model-backed operator-key connection test that omits audience, asserts 400 invalid_audience, and verifies that no grant is created. Also test an audience containing another member.

run() always injects listTools, so the intake tests do not execute validateOperatorKey's fallback or verify that it forwards the entry, trimmed key, and fetcher.

Keep the intake contract in sync with operator-key rows.

submitOperatorKey stores 'operator_key', but IIntegration.config.intake only allows 'oauth'. Typed consumers cannot accurately represent operator-key rows. The route currently imports Integration through untyped require, so this specific update does not need a cast. The schema also has no enum rejection.

Trim the key before storing it. The probe uses the trimmed key, but the stored key is not trimmed.

validateOperatorKey trims key internally and probes tools/list with the trimmed value. The route keeps the raw key and passes it to connectorSecrets.put at Line 89. A pasted key with a trailing newline or space passes the probe. The row then goes connected with an untrimmed secret.

credentialFor returns that secret as the Authorization: Bearer value. A newline is an invalid header value, and the vendor can reject a trailing space. Every later tool call on this row then fails, although intake reported success.

Trim once at the boundary. Then the probe and the stored secret use the same value. Add a route test that submits ' ' + KEY + '\n' and asserts that connectorSecrets.put receives the trimmed key. The current fixture has no surrounding whitespace, so no test catches this.

Clear revokedAt and errorMessage when reconnecting an existing row.

Connection removal sets revokedAt, and credentialFor rejects any row with that field. The operator-key route reuses the existing row but does not clear revokedAt or errorMessage, so a re-pasted key can return 201 connected while credential use still fails with connection was removed.

Proposed fix

-    { $set: { status: 'connected', 'config.credentialRef': credentialRef } },
+    { $set: { status: 'connected', 'config.credentialRef': credentialRef, revokedAt: null, errorMessage: null } },

Test the unknown-installer refusal at this endpoint.

Add a case with the caller’s installation and a second installation without installedBy. Assert 403 with failure: 'unknown_installer', and assert that no probe, row write, or secret write occurs. The existing second-installer test covers only a named installer.

Add a case alongside the second-installer test for an installation with no
installedBy, while retaining the caller’s installation; assert the endpoint
returns 403 with failure 'unknown_installer' and that no probe, row write, or
secret write occurs.

Ported onto current main and finished in #3213 (the four commits there start from this branch's 77dc4f5). This draft gets closed with a link once #3213 merges.

Superseded by #3213, merged as d44dd6e. That PR carries the operator-key hosted-MCP mode with per-agent binding at mint and at call, the key intake and the removal path, rebuilt on current main. Closing this one in its favour. The Latchkey catalogue entry follows as its own data PR.
