+Static tokens grant full access to all tools and resources (no scope restrictions). Sessions authenticated with a
+static token will receive deprecation warnings in the AI client via server instructions and tool results.
+
+Each user can create up to **10 static tokens**.
+
+---
+
+## Authentication
+
+TREK's MCP server supports three authentication methods. OAuth 2.1 is the recommended path for all external clients.
+
+| Method | Token prefix | Access level | TTL | Notes |
+|--------|-------------|-------------|-----|-------|
+| **OAuth 2.1** | `trekoa_` | Scoped (per-consent) | 1 hour | Recommended. Automatically refreshed via 30-day rolling refresh tokens (`trekrf_` prefix). Replay-detected rotation — replayed tokens cascade-revoke the entire chain. |
+| **Static API token** | `trek_` | Full access | No expiry | **Deprecated.** Triggers deprecation warnings in AI clients. Will be removed in a future release. |
+| **Web session JWT** | — | Full access | Session-based | Used internally by the TREK web UI. Not intended for external clients. |
+
+All methods require the `Authorization: Bearer <token>` header (strict scheme enforcement — `Bearer` required).
+
+---
+
+## OAuth Scopes
+
+When connecting via OAuth 2.1, you grant specific scopes during the consent step. TREK registers only the MCP tools
+that match your granted scopes for that session.
+
+| Scope | Permission | Group |
+|-------|-----------|-------|
+| `trips:read` | View trips & itineraries | Trips |
+| `trips:write` | Edit trips & itineraries | Trips |
+| `trips:delete` | Delete trips (irreversible) | Trips |
+| `trips:share` | Manage share links | Trips |
+| `places:read` | View places & map data | Places |
+| `places:write` | Manage places | Places |
+| `atlas:read` | View Atlas | Atlas |
+| `atlas:write` | Manage Atlas | Atlas |
+| `packing:read` | View packing lists | Packing |
+| `packing:write` | Manage packing lists | Packing |
+| `todos:read` | View to-do lists | To-dos |
+| `todos:write` | Manage to-do lists | To-dos |
+| `budget:read` | View budget | Budget |
+| `budget:write` | Manage budget | Budget |
+| `reservations:read` | View reservations | Reservations |
+| `reservations:write` | Manage reservations | Reservations |
+| `collab:read` | View collaboration | Collaboration |
+| `collab:write` | Manage collaboration | Collaboration |
+| `notifications:read` | View notifications | Notifications |
+| `notifications:write` | Manage notifications | Notifications |
+| `vacay:read` | View vacation plans | Vacation |
+| `vacay:write` | Manage vacation plans | Vacation |
+| `geo:read` | Maps & geocoding | Geo |
+| `weather:read` | Weather forecasts | Weather |
+
+**Scope rules:**
+- A `:write` scope implies `:read` access for the same group (e.g. `budget:write` also grants budget read access).
+- Any `trips:*` scope (`trips:read`, `trips:write`, `trips:delete`, or `trips:share`) grants trip read access.
+- `list_trips` and `get_trip_summary` are **always available** regardless of scopes — they are navigation tools.
+- Static tokens and web session JWTs have full access to all tools (equivalent to all scopes).
+- Addon-gated tools (Atlas Extended, Collab, Vacay) require both the relevant scope **and** the addon to be enabled.

+You are connected to TREK, a travel planning application. Below is a compact reference of the data model, key workflows, and behavioral rules you must follow.
+
+## Data model
+
+- **Trip** — top-level container. Has dates, currency, members (owner + collaborators), and optional add-ons.
+- **Day** — one calendar day within a trip (YYYY-MM-DD). Days are generated automatically when a trip is created with start/end dates.
+- **Place** — a point of interest (POI) stored in the trip's place pool. A place is NOT on the itinerary until it is assigned to a day.
+- **Assignment** — links a Place to a Day (ordered, with optional start/end time). This is what builds the daily itinerary.
+- **Accommodation** — a hotel or rental linked to a Place and a check-in/check-out day range.
+- **Reservation** — a booking record (flight, train, restaurant, etc.) with confirmation details, linked to a day.
+- **Day note** — a free-text annotation attached to a day (with optional time label and emoji icon).
+- **Budget item** — an expense entry for a trip (amount, category, payer, split between members).
+- **Packing item** — a checklist entry grouped into bags and categories.
+- **Todo** — a task (not packing-specific) attached to a trip, ordered and togglable.
+- **Tag** — a label that can be applied to places for filtering.
+- **Collab note / poll / message** — shared notes, decision polls, and chat messages for group trips.
+- **Atlas** — global travel journal: bucket list, visited countries and regions.
+- **Vacay** — vacation-day planner that tracks leave across team members and years.
+
+## Key workflows
+
+**Discovering trips:** Always call \`list_trips\` first when no trip ID has been provided. Never assume a trip ID.
+
+**Loading trip context:** Before planning or modifying a trip, call \`get_trip_summary\` once. It returns all days (with assignments and notes), accommodations, budget, packing, reservations, collab notes, and todos in a single round-trip. Use this data to answer follow-up questions without extra tool calls.
+
+**Adding a place to the itinerary (correct order):**
+1. \`search_place\` — find the real-world POI; note the \`osm_id\` and/or \`google_place_id\` in the result.
+2. \`create_place\` — add it to the trip's place pool, passing the IDs from step 1 (enables opening hours, ratings, and map linking in the app).
+3. \`assign_place_to_day\` — schedule it on the desired day using the dayId from \`get_trip_summary\`.
+
+**Creating an accommodation:** A place must exist in the trip first. Create the place (or reuse an existing one), then call \`create_accommodation\` with that \`place_id\` and the \`start_day_id\`/\`end_day_id\`.
+
+**Reordering:** Assignments, todos, packing items, and reservations all support positional reordering via dedicated reorder tools. Always read the current order from \`get_trip_summary\` before reordering.
+
+## Access rules
+
+- The authenticated user can only access trips they own or are a member of. Never guess at trip IDs.
+- Only the trip owner can delete the trip, add members, or remove members.
+- Deleting a place removes all of its day assignments as well — warn the user before doing this.
+- Trips created via MCP are capped at 90 days.
+
+## Dates and times
+
+- All dates use ISO format: **YYYY-MM-DD**.
+- Times are strings like **"09:00"** or **"14:30"** (24-hour). Pass \`null\` to clear a time.
+- When displaying dates to users, use a friendly human-readable format (e.g. "Mon, Apr 14").
+
+## Add-on features
+
+The following features are optional and may not be available on every TREK instance. Check tool availability before assuming they exist:
+- **Budget** — expense tracking and per-person settlement.
+- **Packing** — checklist with bags, categories, and templates.
+- **Collab** — shared notes, polls, and chat messages for group trips.
+- **Atlas** — bucket list and visited-country/region tracking.
+- **Vacay** — team vacation-day planner with public holiday integration.
+
+## Behavioral rules
+
+- Prefer \`get_trip_summary\` over individual list tools when you need a full picture — it is one call instead of many.
+- Use \`search_place\` before \`create_place\` so the app gets structured POI data (coordinates, address, opening hours). Do not skip this step.
+- When the user asks to "add X to day Y", resolve both the place (search + create if needed) and the day ID before calling \`assign_place_to_day\`.
+- Do not batch destructive operations (delete trip, delete day, delete place) without explicit user confirmation for each.
+- Present budget amounts with the trip's currency. Use \`get_trip_summary\` to read the currency field.
+- For group trips, always check member IDs via \`list_trip_members\` before calling tools that require a \`userId\` (e.g. budget splits, assignment participants).
