## Findings

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

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

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


## Can't be undone (1)

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

### `ch_connections`

- 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
Journeys between two places in Switzerland by train, bus, tram or boat (SBB/CFF/FFS, PostBus and all Swiss operators): departure and arrival times, platforms, transfers, live delays.
Use when: someone needs to travel by public transport in Switzerland (e.g. Zürich to Geneva).
Example: {"from":"Zürich HB","to":"Genève"}
```

## Changes things (1)

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

### `ch_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
Next departures (train, bus, tram) from one Swiss station or stop: time, line, destination, platform, live delay.
Use when: someone is at (or going to) a Swiss station and wants the next departures.
Example: {"station":"Bern"}
```

## Only reads (1)

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

### `ch_find_station`

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

Description, as the server wrote it:

```untrusted-server-text
Finds the exact Swiss station or stop names matching a word (German, French or Italian names).
Use when: a place name is ambiguous or misspelled.
Example: {"query":"Lausanne"}
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__transit-switzerland__ch_find_station"
    ],
    "ask": [
      "mcp__transit-switzerland__ch_connections",
      "mcp__transit-switzerland__ch_station_departures"
    ],
    "deny": []
  }
}
```
