    Description, as the server wrote it
    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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
