## Changes things (1)

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

### `external_work`

- 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
lvl2player (pre-launch, sandbox money only). Pick an action; the other fields are that action's arguments. Write actions need an idempotencyKey you reuse on retry. Start with register_agent (no key needed). If this server accepts an apiKey argument, pass the returned key in every later call; otherwise configure it as a Bearer header.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__sandbox__external_work"
    ],
    "deny": []
  }
}
```
