Root cause: claude.ai's MCP connector (spec 2025-06-18) requires the resource server
to publish Protected Resource Metadata and return WWW-Authenticate on 401s to bind
the /mcp endpoint to its AS. Without these, it silently shows no tools after OAuth.
- Add /.well-known/oauth-protected-resource (RFC 9728) with addon gating
- Emit WWW-Authenticate: Bearer resource_metadata=... on 401/auth-failure 403s
- Open CORS (origin: *) on both .well-known/* endpoints per RFC 8414/9728
- Accept resource parameter at authorize + token endpoints (RFC 8707)
- Store audience on oauth_tokens; validate on every MCP request
- Refresh tokens inherit audience; add resource_parameter_supported to AS metadata
- DB migration: ADD COLUMN audience TEXT to oauth_tokens
- Gate collab MCP tools/resources by chat/notes/polls sub-features individually
- Invalidate MCP sessions when collab sub-features are toggled in admin
- Update test mocks and MCP.md
- Add Journey addon tools (list, get, entries, contributors, suggestions,
available trips, create/update/delete journey and entries, reorder,
contributors CRUD, preferences, share link management)
- Add Journey resources (trek://journeys and sub-resources)
- Split transport (flight/train/car/cruise) into dedicated tools with
endpoints[] and needs_review support; narrow reservation types to
non-transport only
- Add airport lookup tools (search_airports, get_airport) under geo:read
- Add import_places_from_url and bulk_delete_places to places tools
- Add journey:read/write/share OAuth scopes (27 total) with translations
across all 15 locales
- Default end_day to start_day when creating a transport (MCP + UI)
- Fix MCP.md drift: addon gates, removed files resource, corrected
get_trip_summary description, todos under Packing addon
- Split `media:read` into `geo:read` and `weather:read` scopes
- Add dedicated `atlas:read/write` scopes (previously under `places`)
- Add dedicated `todos:read/write` scopes (previously under `collab`)
- Rate limiting now keyed by userId+clientId instead of userId alone
- Bind MCP sessions to the OAuth client that created them
- Log MCP tool calls to audit log with clientId
- Invalidate all MCP sessions on addon state change
- Reduce session sweep interval from 10min to 1min
- Update all translations with new scope labels
OAuth 2.1 authentication for MCP:
- Add OAuth 2.1 authorization server with PKCE support (routes/oauth.ts)
- Add OAuth service for client CRUD, auth-code flow, and token management (services/oauthService.ts)
- Add typed scope definitions and enforcement helpers (mcp/scopes.ts)
- Add OAuth consent UI page (OAuthAuthorizePage.tsx)
- Add client-side scope labels and descriptions (api/oauthScopes.ts)
- Integrate OAuth token auth into MCP handler alongside existing static tokens
- All OAuth endpoints gated on `mcp` addon
Addon gating across MCP tools, resources, and prompts:
- Add typed ADDON_IDS constant (server/src/addons.ts) replacing all string literals
- Gate budget tools and resources (trip-budget, per-person, settlement) on `budget` addon
- Gate packing tools and resources (trip-packing, trip-packing-bags, trip-todos) on `packing` addon
- Gate todos tools on `packing` addon (mirrors web UI Lists tab behavior)
- Expand atlas gate to cover full tool body (bucket-list + country tools no longer leak)
- Expand collab gate to cover full tool body (collab notes no longer leak)
- Gate packing-list and budget-overview MCP prompts on their respective addons
- Gate get_trip_summary sections per addon; blank packing/budget/collab_notes/todos when disabled
- Remove trip-files resource and files field from get_trip_summary
- Replace all isAddonEnabled('literal') calls with ADDON_IDS constants
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- Add tool annotations (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to all 40+ tools
- Register 3 MCP prompts: trip-summary, packing-list, budget-overview
- Add explicit mimeType: application/json to all resource registrations
- Announce capabilities with listChanged on resources, tools, prompts
- Update server name to 'TREK MCP' in MCP initialization
Replace all db.prepare() calls in mcp/index.ts, mcp/resources.ts, and
mcp/tools.ts with calls to the service layer. Add missing service functions:
- authService: isDemoUser, verifyMcpToken, verifyJwtToken
- adminService: isAddonEnabled
- atlasService: listVisitedCountries
- tripService: getTripSummary, listTrips with null archived param
Also fix getAssignmentWithPlace and formatAssignmentWithPlace to expose
place_id, assignment_time, and assignment_end_time at the top level, and
fix updateDay to correctly handle null title for clearing.
Add comprehensive unit and integration test suite for the MCP layer (821 tests all passing).
