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
