Do not merge: Cloud MCP demo build (#1137 + #994 on main) - #1140
Aaron ("AJ") Steers (aaronsteers) wants to merge 25 commits into
Conversation
…og on existing connections Adds two new MCP tools: - refresh_connection_catalog: Triggers a discover operation on a connection's source and updates the catalog with latest stream definitions and sync modes - set_stream_sync_mode: Safely changes the sync mode for a specific stream on a connection, with validation that the mode is supported Core logic lives in CloudConnection (connections.py) and api_util.py, with MCP tools as thin wrappers per the presentation layer pattern. Closes #993 Co-Authored-By: AJ Steers <aj@airbyte.io>
…am_sync_mode Addresses CodeRabbit review feedback: - Add stream_namespace parameter to disambiguate same-named streams in different namespaces. Raises PyAirbyteInputError when name is ambiguous. - Add fail-fast guard when switching to incremental mode without a usable cursor field (no existing cursor, no default cursor, no source-defined cursor).

🔵 Needs a closer look
It introduces new public-facing endpoints and security-sensitive token/capability handling plus destructive Cloud mutation tools that warrant focused human security and behavior validation before approval.
Pull request overview
This PR assembles a throwaway “Cloud MCP demo build” branch (explicitly do not merge) by combining two feature sets on top of main: (1) a secret-free, stateless connector configuration form delivered as an MCP App widget and standalone page, and (2) Cloud connection-management MCP tools for refreshing a connection catalog and changing a stream’s sync mode.
Changes:
- Adds an interactive connector configuration form (
show_connector_config_form) that mints encrypted one-shot submit tokens and supports both MCP Apps and a standalone browser page flow. - Introduces a stateless
/connector-config-submitendpoint and token machinery for one-shot create/update/validate actions without echoing secrets. - Adds Cloud MCP tools and core methods to refresh a connection’s catalog and update a stream’s sync settings.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Forward config_api_root during catalog refresh.
Could you pass self.workspace.config_api_root to both Config API calls and add config_api_root to get_refreshed_connection_catalog()? The workspace supports an explicit Config API root. These calls omit it. A custom api_root that cannot derive /api/v1 causes refresh_catalog() to raise NotImplementedError even when the workspace has a valid Config API root. Wdyt?

Make catalog replacements conflict-safe.
When concurrent refresh_catalog() or set_stream_sync_mode() calls read the same catalog, api_util.replace_connection_catalog() replaces the entire syncCatalog without a revision check, stream patch, serialization, or retry. The later write can remove an earlier update to another stream. Could you use an atomic stream patch or a revision-qualified update with conflict retry?

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Could we require a shared AIRBYTE_MCP_FORM_SIGNING_KEY for multi-worker deployments? Independently initialized processes generate different _PROCESS_SIGNING_KEY values, so a token minted on one replica can reach another and receive 403 from /connector-config-submit. This is separate from process-local replay tracking.

Offload the registry fetch from the event loop
connector_config_form_endpoint directly calls synchronous _connector_spec_schema, which performs up to two blocking requests.get calls. Each call has a 10-second timeout. This can block the event loop and delay health checks and other MCP requests. Could you call _connector_spec_schema with anyio.to_thread.run_sync and remove noqa: RUF029? wdyt?

In `@airbyte/mcp/interactive/_connector_config_form_ui.py` at line 415, Update
connector_config_form_endpoint to invoke the synchronous _connector_spec_schema
through anyio.to_thread.run_sync, await its result, and remove the RUF029
suppression associated with the direct call so registry requests do not block
the event loop.

Enforce read-only mode on connector form submissions
airbyte_readonly_mode_filter only filters MCP tools. The submit route still executes create and update tokens without checking read-only mode. Could _mint_form_token issue only validate tokens, with _execute_action enforcing the restriction as a defense in depth? wdyt?

Update _mint_form_token to issue only validate tokens when read-only mode is
enabled, preventing create and update submissions; also add a read-only guard in
_execute_action so those actions are rejected even if an unsafe token is
presented.

Summary
Throwaway demo branch requested by AJ Steers (aaronsteers) — do not merge. It exists only to get a single
cloud-mcp-previewdeploy containing the unmerged Cloud MCP features we want to demo together on top of currentmain.Contents (merged with
--no-ff, no conflicts, no extra fix commits; source branches untouched):show_connector_config_form: secret-free connector config via MCP Apps widget / standalone form page with stateless one-shot submit.set_stream_sync_mode+refresh_connection_catalogCloud connection-management tools.Everything else in the demo (Agents
execute/inspect, org/workspace discovery, check/cancel) is already onmain.Verified locally:
