## Findings

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

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

annotations: {"readOnlyHint":true,"openWorldHint":true}; The name "nearby_stops" says "stop": a word for a change.
```


## Changes things (6)

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

### `data_sources`

- 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
Which carriers/feeds are loaded, their validity dates, licences and required attribution; which feeds can be enabled.
```

### `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
Departure (or arrival) board for a station or stop: time, live delay, train/bus line, platform, destination and main stops. Optionally only services going towards a given place.
```

### `nearby_stops`

- The name "nearby_stops" says "stop": 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
Stations and stops within a radius of coordinates (e.g. after geocoding an address).
```

### `rail_disruptions`

- 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
Current and upcoming disruptions on Polish railway lines from PKP PLK: track closures, replacement buses (ZKA), cancellations, diversions. Optional `query` filters by station name or text (e.g. "Kraków", "ZKA"). plan_journey, departures and trip_details already flag affected trains.
```

### `trip_details`

- 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
All stops of one train or bus run with times, platforms and live delays/cancellations. Identify it by `ref` (from plan_journey/departures) or by train number/name (e.g. '3510', 'IC 3510', 'Podhalanin') plus date.
```

### `weather_warnings`

- 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
Official IMGW-PIB meteorological warnings (storm, wind, frost, heat, snow, ice...) and flood warnings in Poland. With `place` (town, station or "lat,lon"): warnings for its county (powiat); without: national overview. plan_journey already adds warnings for the start and destination.
```

## Only reads (2)

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

### `find_stops`

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

Description, as the server wrote it:

```untrusted-server-text
Search stations/stops by name (fuzzy, diacritics optional). Shows modes, coordinates and source feeds.
```

### `plan_journey`

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

Description, as the server wrote it:

```untrusted-server-text
Find connections between two places in Poland, including changes between trains and buses (PKS). from/to accept a station name ("Poznań Główny"), a town ("Zakopane" = all its stops) or coordinates "52.40,16.91". Returns several options with times, platforms, operators, changes and live delays (today).
```
