## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `fact_keys`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Every fact key with its type, allowed values and label.
```

### `facts_by_key`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
One fact across all stations or lines, e.g. key "shower" for every station with a known shower. Use fact_keys for the list.
```

### `punctuality`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
How late night trains really arrive, per train, counted every night by us from Fintraffic and Trafikverket open data: on-time share (within 5 minutes at the last stop), median and 90th percentile delay, cancellations. Filter by line id, train number or country (FI, SE).
```

## Only reads (4)

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

All published facts for one night train line (power sockets, bikes, pets, food on board, booking window...) with source and date, and its stations in order.
```

### `get_station`

```

### `list_lines`

### `search_stations`
