• create_eventCreate calendar event

  Create a new event in a writable iCloud calendar and return the stored representation; existing events are not changed. Use list_calendars first to obtain calendar_id, and use update_event when the event already exists. Timed values require matching offsets and timezones, all-day end dates are exclusive, recurrence rules omit the RRULE: prefix, and travel_minutes sets Apple Calendar travel time for timed events.

• delete_eventDelete calendar eventcan change or delete data

  Permanently delete an event or entire recurring series; individual expanded occurrences are not supported. Target it by resource_id or by calendar_id with uid, and supply expected_etag when available to prevent deleting a concurrently changed event.

• get_eventGet calendar eventread-only

  Read one event by resource_id, preferably from a previous result, or by the calendar_id and uid pair. Use list_events for range searches. Request raw iCalendar only for controlled diagnostics because it may contain sensitive calendar data.

• list_calendarsList calendarsread-only

  List calendars available in the configured iCloud account. Use this first to obtain the opaque calendar_id required by list_events and create_event; writable is a best-effort capability indicator.

• list_eventsList calendar eventsread-only

  List events that overlap the start-inclusive, end-exclusive interval and expand recurring series into occurrences, across at most 366 days. Use list_calendars first to obtain calendar_id and use get_event instead for one known event. Continue with next_cursor and unchanged query filters when more results are available.

• update_eventUpdate calendar eventcan change or delete data

  Modify an existing event or entire recurring series; individual expanded occurrences are not supported. Target it by resource_id or by calendar_id with uid. Omitted patch fields are preserved, null clears nullable fields, an empty alarms array removes alarms, and expected_etag can prevent a stale write.
