## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `crossplay_check`

- 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
Whether a game can be played together between two platforms (e.g. PS5 and PC).
```

## Only reads (2)

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

### `get_game`

- The name "get_game" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Multiplayer details of one game: platforms, online and same-screen player counts, crossplay between each pair of platforms, session length and link to its CoopGames page.
```

### `search_games`

- The name "search_games" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search CoopGames' catalog of co-op and multiplayer games for friends (PC, PS5, PS4, Xbox, Switch). Filters combine with AND. With several platforms it returns only games with crossplay between all of them. Results are most popular first.
```

## Claude Code permissions
