## Findings

No check matched anything in these tool definitions.


## Changes things (4)

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

### `add_player`

- The name "add_player" says "add": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Register one player by name. Returns a 6-character code and a personal URL so the player can be identified at the courts without an account.
```

### `create_ladder`

- The name "create_ladder" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Create or update the club ladder: club name and sport. Returns the join URL (the poster target) that players scan.
```

### `record_match`

- 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
Record a finished match result. Identify players by name, numeric id, or 6-character code. Give the set score (sets_a, sets_b) and optionally the games.
```

### `schedule_match`

- The name "schedule_match" says "schedule": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Put a match on the calendar before it is played. It appears as a pending card in the standings output.
```

## Only reads (1)

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

### `get_standings`

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

Description, as the server wrote it:

```untrusted-server-text
The current table (rank, wins, losses, set percentage) plus the single most useful match to play next. Standings are computed with a fixed rule order, so the same results always give the same table.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `board`:

```json
{
  "permissions": {
    "allow": [
      "mcp__board__get_standings"
    ],
    "ask": [
      "mcp__board__create_ladder",
      "mcp__board__add_player",
      "mcp__board__record_match",
      "mcp__board__schedule_match"
    ],
    "deny": []
  }
}
```
