## Findings

- **warn** Annotations that disagree with the tool in `plan_journey` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "plan_journey" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The input addresses people (input.to): what it sends cannot be taken back.
```

- **warn** Annotations that disagree with the tool in `check_train_options` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "check_train_options" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"idempotentHint":false,"openWorldHint":true}; The input addresses people (input.to): what it sends cannot be taken back.
```

- **warn** Annotations that disagree with the tool in `train_schedule` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "train_schedule" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The name "train_schedule" says "schedule": a word for a change.
```

- **warn** Annotations that disagree with the tool in `journey_calendar` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "journey_calendar" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The input addresses people (input.to): what it sends cannot be taken back.
```


## Can't be undone (3)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `check_train_options`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Live seat availability per class for one train on one date, plus every other way to book it when the through ticket will not confirm: a split at an intermediate station, boarding earlier, alighting later. This is the tool that rescues a waitlisted train. It spends a metered upstream call, so ask it about trains the traveller is actually considering rather than sweeping a list.
```

### `journey_calendar`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Day-by-day service over a span of dates for a station pair: which days have a direct train and which have none, plus the weekly pattern. Use this when somebody is flexible about when they travel, or asks 'does it run on Sundays'. Timetable only — it says nothing about seats.
```

### `plan_journey`

- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Every practical way to get from one place to another: direct trains with their fares per class, journeys with one change of train, flights, mixed train-and-flight itineraries, and GOVERNMENT BUSES from the state road transport corporations, priced from their own reservation systems. This is the whole answer in one call. Place ids come from find_place.

Use it for bus questions too. On a large share of the corridors these corporations serve there is no through train at all — Mysuru to Mangaluru runs twenty-five buses a day and not one direct train — so a journey this tool answers with a bus is often the only through service that exists, not a second-best.

Pass `train_class` when the traveller has named one ("3A", "sleeper") and every train is priced in it; leave it out and each train is priced in every class we have evidence it carries. Pass `modes: "trains_only"` when they have said train — do not ask them to choose otherwise, because the point of this planner is that they do not have to. Pass `arrive_by: true` when they named a time they must BE somewhere rather than a time they want to leave.
```

## Changes things (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `nearby_stations`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Other railway stations within a radius of one station, nearest first. Useful when a place has no service of its own and the traveller needs to know what is reachable — the planner already does this internally, so reach for it only when somebody asks the question directly.
```

### `station_departures`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Every train scheduled to call at a station, in departure order — the enquiry board, not a journey plan. Use plan_journey when somebody wants to get somewhere; use this when they are asking what leaves from here. Scheduled times only.
```

### `train_schedule`

- The name "train_schedule" says "schedule": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Every stop of one train with its scheduled arrival and departure, in order. Scheduled times only — this says nothing about where the train is today.
```

## Only reads (2)

Looks things up and changes nothing. Claude Code: allow.

### `find_place`

- The name "find_place" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Turn what somebody typed into RailRoute place ids. ALWAYS call this before plan_journey. A place is a city with all of its stations and airports — Mumbai covers CSMT, LTT, Dadar, Bandra Terminus and the airport — so the planner can choose the right terminal rather than making the traveller do it. Typing a station code ("CSMT") finds the city and says which terminal matched.
```

### `next_confirmed_date`

- The description's first verb is "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search forward up to a month for the first date this route can actually be travelled with a confirmed berth — direct trains and one-change journeys together. Use it when a traveller is flexible about WHEN and the date they asked for is waitlisted. EXPENSIVE: it checks seats across dozens of trains and dates, so it is limited to a few calls an hour; for a single date use check_train_options instead.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `journey-planner`:

```json
{
  "permissions": {
    "allow": [
      "mcp__journey-planner__find_place",
      "mcp__journey-planner__next_confirmed_date"
    ],
    "ask": [
      "mcp__journey-planner__plan_journey",
      "mcp__journey-planner__check_train_options",
      "mcp__journey-planner__train_schedule",
      "mcp__journey-planner__station_departures",
      "mcp__journey-planner__journey_calendar",
      "mcp__journey-planner__nearby_stations"
    ],
    "deny": []
  }
}
