Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟡create_agent(name, type, description)
Register your agent (AI assistant, human participant, or resource) with Chronary so it can own calendars, events, and webhooks.

}🟡create_calendar(name, agent_id, timezone, default_reminders)
Create a calendar to hold events and track availability. Calendars are required before creating events — call this first when setting up a new agent. An agent can have multiple calendars (e.g. "Work", "Personal"). Org-level calendars (no agent_id) can be used as shared resources like meeting rooms.

}🟡create_event(calendar_id, title, start_time, end_time, description, ...)
Create a booking, appointment, meeting, hold, or any scheduled event on a calendar. The calendar_id comes from create_calendar or list_events. Once created, this event blocks the agent's availability during that time and appears in availability queries. Use status="hold" with hold_expires_at to tentatively reserve a slot that auto-releases on TTL.

}🟢get_event(event_id, calendar_id)
Retrieve a single event by ID, including its title, times, status, location, reminders, and metadata. Works for both internally created events and externally synced iCal events. `calendar_id` is optional — if omitted the calendar is resolved from the event. Provide `calendar_id` to fail fast on cross-calendar typos.

}🟡update_event(event_id, calendar_id, title, description, start_time, ...)
Reschedule or edit an event — change its title, description, start/end times, location, status, reminders, or metadata. Use this to move an appointment to a new time or update its details. Provide only the fields you want to change. Holds cannot be edited via this tool (use confirm_event / release_event). External iCal events are read-only. `calendar_id` is optional — if omitted it is resolved from the event.

}🔴cancel_event(event_id, calendar_id, occurrence_start)
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 from future availability calculations. For a recurring series, pass `occurrence_start` to cancel just that one occurrence (the series continues); omit it to cancel the whole series. `calendar_id` is optional — if omitted the calendar is looked up from the event. Provide `calendar_id` to fail fast on cross-calendar typos.

Link an external iCal feed (e.g. a human's Google Calendar) to an agent's calendar so external events appear in availability calculations.

Get a calendar's temporal context in a single call: the current event (if one is happening now), the next upcoming event, recent past events, a short upcoming window, and the owning agent's status (idle/working/waiting/error).
