### `fetch_events`

- The name "fetch_events" says "fetch": a word for reading.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Find upcoming local events — community programs, markets, festivals, fitness classes, workshops, and entertainment. Filter by city, neighbourhood, sector, date range, and accessibility flags. Returns rich metadata including geo coordinates, images, structured pricing, recurrence, and accessibility info. Connect and list the paid event tool without a Citybook key. Credential-free fetch_events calls require x402 payment; other tools require Bearer authentication.
```

## Claude Code permissions

    "deny": []
  }
