* feat(mcp): add public transit planning tools * refactor(transit): reuse local time conversion * fix(mcp): harden transit journey validation * refactor(transit): centralize itinerary processing * fix(mcp): return the transit itineraries the provider actually offers search_transit_routes validated each itinerary leg's mode against SCHEDULED_TRANSIT_MODES, but that constant is the request-side filter whitelist — the modes a caller may ask for — not the modes MOTIS can return. Its default TRANSIT mode expands to TRAM,FERRY,AIRPLANE,BUS,COACH,RAIL,ODM, RIDE_SHARING,FUNICULAR,AERIAL_LIFT,OTHER, and street legs can be BIKE/CAR/ RENTAL. Any itinerary carrying one of those failed the parse and was dropped by the flatMap, so the tool reported fewer routes than exist — or none at all. Against the live provider, Trondheim → Ålesund returns 5 itineraries and 3 of them contain an AIRPLANE leg, so the tool silently discarded them; the web app shows all 5, because it treats mode as a free string and renders anything non-WALK as a transit leg. Accept any mode token on a leg and keep the existing "at least one non-WALK leg" rule as the real gate, which restores parity with the web app. Everything downstream keeps its mode !== 'WALK' semantics, so a journey created over MCP is identical to one created in the app. Dropping an itinerary is still possible when provider data fails the remaining consistency rules, but it is indistinguishable from "no routes exist" — so search_transit_routes now reports a `dropped` count alongside the results. --------- Co-authored-by: Uzini <43294422+Uziniii@users.noreply.github.com>

# MCP Scopes
|
|
|
|
OAuth scopes control exactly which data your AI client can read or write in TREK. You select scopes during the OAuth consent screen or when pre-creating an OAuth client. You can revoke access at any time by deleting the OAuth client or token from **Settings → Integrations → MCP**.
|
|
|
|
|
|
|
|
## All scopes
|
|
|
|
TREK defines 27 scopes across 13 groups.
|
|
|
|
| Group | Scope | Permission |
|
|
|---|---|---|
|
|
| **Trips** | `trips:read` | View trips, days, day notes, and members |
|
|
| | `trips:write` | Create, update, and delete trips, days, day notes, and accommodations; manage members; duplicate trips |
|
|
| | `trips:delete` | Permanently delete entire trips (irreversible) |
|
|
| | `trips:share` | Create, update, and revoke public share links for trips |
|
|
| **Places** | `places:read` | Read places, day assignments, tags, and categories |
|
|
| | `places:write` | Create, update, and delete places, assignments, and tags |
|
|
| **Atlas** | `atlas:read` | Read visited countries, regions, and bucket list |
|
|
| | `atlas:write` | Mark countries and regions visited, manage bucket list |
|
|
| **Packing** | `packing:read` | Read packing items, bags, and category assignees |
|
|
| | `packing:write` | Add, update, delete, toggle, and reorder packing items and bags |
|
|
| **To-dos** | `todos:read` | Read trip to-do items and category assignees |
|
|
| | `todos:write` | Create, update, toggle, delete, and reorder to-do items |
|
|
| **Budget** | `budget:read` | Read budget items and expense breakdown |
|
|
| | `budget:write` | Create, update, and delete budget items |
|
|
| **Reservations** | `reservations:read` | Read reservations and accommodation details |
|
|
| | `reservations:write` | Create, update, delete, and reorder reservations |
|
|
| **Collaboration** | `collab:read` | Read collab notes, polls, and messages |
|
|
| | `collab:write` | Create, update, and delete collab notes, polls, and messages |
|
|
| **Notifications** | `notifications:read` | Read in-app notifications and unread counts |
|
|
| | `notifications:write` | Mark notifications as read or unread (individually or all at once) |
|
|
| **Vacation** | `vacay:read` | Read vacation planning data, entries, and stats |
|
|
| | `vacay:write` | Create and manage vacation entries, holidays, and team plans |
|
|
| **Geo** | `geo:read` | Search locations and public transit routes, resolve map URLs, and reverse-geocode coordinates |
|
|
| **Weather** | `weather:read` | Fetch weather forecasts for trip locations and dates |
|
|
| **Journey** | `journey:read` | Read journeys, entries, and contributor list |
|
|
| | `journey:write` | Create, update, and delete journeys and their entries |
|
|
| | `journey:share` | Create, update, and revoke public share links for journeys |
|
|
|
|
## Scope rules
|
|
|
|
- A `:write` scope implies `:read` access for the same group (e.g. `budget:write` also grants read access to budget data).
|
|
- Any `trips:*` scope (`trips:read`, `trips:write`, `trips:delete`, or `trips:share`) grants trip read access.
|
|
- `journey:read` or `journey:write` grants journey read access. `journey:share` alone does **not** grant read access — it only enables managing public share links.
|
|
- `list_trips` and `get_trip_summary` are always available regardless of scope — they are navigation tools.
|
|
- Static tokens and web session JWTs have full access equivalent to all scopes.
|
|
- Addon-gated tools (Atlas, Collab, Vacay, Journey) require both the relevant scope **and** the corresponding addon to be enabled by an admin.
|
|
|
|
## Choosing the right scopes
|
|
|
|
Grant only what you need. Some examples:
|
|
|
|
| Use case | Minimum scopes |
|
|
|---|---|
|
|
| Read-only AI assistant | All `:read` scopes relevant to your data |
|
|
| Full trip planner | All scopes except `:delete` (use the Claude.ai or Claude Desktop preset) |
|
|
| Budget review only | `trips:read` + `budget:read` |
|
|
| Packing list assistant | `trips:read` + `packing:read` + `packing:write` |
|
|
| Journey writer | `trips:read` + `journey:read` + `journey:write` |
|
|
|
|
The preset buttons in **Settings → Integrations → MCP → OAuth Clients** fill in a reasonable scope set for common clients. VS Code defaults to read-only scopes; Claude.ai and Claude Desktop default to all scopes except `:delete`.
