## Tools (54)

- `accept_terms`: Re-accept the current Chronary terms of service on behalf of the calling org. Use this when responses carry the Chronary-Terms-Upgrade-Required header — a mater
- `cancel_connection_link`: Cancel a pending human-calendar setup request. This invalidates the setup URL and does not disconnect an already completed Google or Microsoft connection.
- `cancel_event`: Delete or cancel an event from a calendar. Use this to remove, cancel, or delete any scheduled event or appointment. The event is marked cancelled and excluded 
- `cancel_proposal`: Cancel an open proposal. Fires a proposal.cancelled webhook with reason="organizer_cancelled". Requires an org-level API key. Pro plan only.
- `clear_availability_rules`: Remove the availability rules from a calendar, reverting to the default (no buffers, no working-hours mask). Returns the deleted row, or an error if none were s
- `confirm_event`: Promote a held event to a confirmed booking. The event must currently have status="hold" and its hold_expires_at must not have passed. After confirmation, event
- `create_agent`: Register your agent (AI assistant, human participant, or resource) with Chronary so it can own calendars, events, and webhooks.
- `create_booking_page`: Create a public booking page (a hosted scheduling link) for a calendar. Returns a booking_url to send to a human; when they pick a slot, a confirmed event is cr
