- 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
Adds an OAuth 2.1 public client registration flow so MCP clients can
self-register via a user-facing consent page instead of requiring manual
setup in Settings.
Server:
- DB migration adds `is_public` and `created_via` columns to oauth_clients
- New GET /api/oauth/register/validate — validates DCR params, returns
requested scopes; unauthenticated callers get loginRequired flag
- New POST /api/oauth/register — creates a public client, saves consent,
and redirects with client_id (cookie auth required)
- `authenticateClient` / `refreshTokens` skip secret check for public
clients (PKCE provides the security guarantee)
- `createOAuthClient` accepts options for isPublic/createdVia; public
clients store an opaque secret hash instead of a usable secret
- `rotateOAuthClientSecret` blocked on public clients
- `isValidRedirectUri` extracted as a shared helper
- Discovery metadata now advertises registration_endpoint and auth method
`none`; token/revoke endpoints no longer require client_secret for
public clients
Client:
- New OAuthRegisterPage (/oauth/register) — loading → optional
login-required gate → scope selection → done states
- New ScopeGroupPicker component — collapsible groups, indeterminate
checkboxes, select-all per group or globally
- oauthApi.register.{validate,submit} added to api/client.ts
- apiClient exported so it can be reused outside api/client.ts
- IntegrationsTab tests fixed for new collapsible section structure
- collab_notes fallback changed from undefined to [] in MCP trip tools
Claude retried the tool silently and answered without mentioning the
notice. Two fixes:
1. Include actual trip data in the same isError response so no retry
is needed and Claude has both the warning and the answer in one shot.
2. Reword the notice to instruct Claude to include the warning verbatim
in its response before answering the user's question.
Claude stopped after surfacing the error rather than retrying.
Append an explicit instruction to retry the tool call so the user
gets both the deprecation warning and their actual answer.
isError: true is the one MCP mechanism Claude.ai cannot ignore —
it is obligated to surface tool errors to the user.
On the first tool call of a static-token session, return only the
deprecation notice with isError: true (no data). The per-session
_noticeEmitted flag is set before returning, so the immediate retry
(or any subsequent call) goes through normally and returns real data.
Claude.ai filters out prepended content items as metadata but must
process top-level JSON fields as response data, making it far more
likely to surface the notice to the user.
Navigation tools:
- list_trips and get_trip_summary are now always registered for any
OAuth session regardless of granted scopes — they are required for
trip ID discovery before any scoped tool can be used
- get_trip_summary filters optional sections (budget, packing, collab,
reservations) by the client's OAuth scopes when called without trips:read
Deprecation notice:
- Inject static token deprecation warning into the first tool result
(list_trips or get_trip_summary) via a per-session closure so Claude
is forced to surface it — the instructions field alone is only
background context and is not proactively shown to the user
UI:
- OAuth client creation modal: add hint explaining the always-available
tools, remove the "must select at least one scope" submit guard
- OAuth consent screen: add "Always included" section showing list_trips
and get_trip_summary; handles zero-scope clients gracefully (empty
permissions section is hidden)
Injects a structured BASE_MCP_INSTRUCTIONS string into every session's
initialize response so Claude has data model, workflow, and behavioral
context without needing to infer it from tool names alone.
Covers: data model hierarchy (trip→day→place→assignment), key discovery
workflow (list_trips → get_trip_summary), correct place-to-itinerary
flow (search_place → create_place → assign_place_to_day), accommodation
creation order, access rules, date/time format, add-on feature list,
and common pitfalls (e.g. don't skip search_place, confirm before bulk
deletes).
Static token deprecation notice is appended on top when applicable.
The deprecation warning was registered as an MCP prompt that clients
must explicitly fetch — it never fired automatically. Move it to the
ServerOptions.instructions field, which is returned in the initialize
response and automatically read by Claude and other MCP clients as
system context.
Introduce trips:share as a dedicated OAuth scope for managing public
share links, decoupled from trips:read and trips:write. Share link
tools (get/create/delete_share_link) now gate on canShareTrips()
instead of the generic read/write scopes. Scope added to both client
and server definitions with full test coverage.
Redesign the consent screen from a narrow single-column card
(max-w-sm) to a two-panel layout (max-w-2xl): app identity and
action buttons on the left, scrollable scope list on the right.
Responsive — stacks vertically on mobile.
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

Expand get_trip_summary to return full budget line items and full
packing list (with checked status) instead of totals/stats only.
Update tool description to accurately reflect all returned data
including todos, files, and collab poll/message counts.
- Move safeBroadcast after all imports (was incorrectly placed between import blocks)
- Replace dynamic import of packingService in packing-list prompt with static import
- Fix reorder_day_assignments annotation from NON_IDEMPOTENT to WRITE (reordering is idempotent)
- Fix misleading osm_id description in update_place (removed "create-only" claim)
- Remove internal error detail leakage from MCP 500 responses
- 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
The search_place MCP tool was hardcoding a direct Nominatim call, ignoring
any configured Google Maps API key and never returning google_place_id despite
the tool description advertising it. Replace the inline fetch with the existing
searchPlaces() service which already switches between Google and Nominatim.
Update unit tests to mock mapsService instead of global fetch, and add a
dedicated test case for the Google path returning google_place_id.
Closes#424
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).
Adds optional check_in and check_out fields to create_reservation and
link_hotel_accommodation so MCP clients can set accommodation times,
matching the existing REST API behaviour.
Closes#363
- Add google_place_id and osm_id params to create_place tool so the app
can fetch opening hours and ratings for MCP-created places
- Add list_categories tool for discovering category IDs
- Add search_place tool (Nominatim) to look up osm_id before creating
- Add { algorithms: ['HS256'] } to all jwt.verify() calls to prevent
algorithm confusion attacks (including the 'none' algorithm)
- Add { algorithm: 'HS256' } to all jwt.sign() calls for consistency
- Reduce OIDC token payload to only { id } (was leaking username, email, role)
- Validate OIDC redirect URI against APP_URL env var when configured
- Add startup warning when JWT_SECRET is auto-generated
