create_eventCreate Event
Create a new event in Calendar.app. Goes through AppleScript so Calendar.app syncs the new event to all connected accounts. Returns the uid of the created event. Supports recurring events via the recurrence field.
delete_eventDelete Eventcan change or delete data
Permanently delete a Calendar.app event identified by its uid. Goes through AppleScript so the deletion syncs to all connected accounts. This action cannot be undone.
get_eventGet Eventread-only
Get full details of a single Calendar.app event by UUID, including attendees and all metadata. The uuid field is returned by list_events and search_events.
list_calendarsList Calendarsread-only
List all Calendar.app calendars across all accounts, with name, UUID, color, and account info. UUIDs can be passed to list_events, search_events, and get_event to filter by calendar.
list_eventsList Eventsread-only
List calendar events within a date range. Queries the Calendar.app SQLite database via OccurrenceCache, which correctly expands recurring event instances rather than just listing master events. Returns events sorted by start time.
search_eventsSearch Eventsread-only
Search Calendar.app events by text across title, description, and location. Queries CalendarItem directly for fast full-text matching. For recurring events returns the master event; use list_events for occurrence-level detail.
update_eventUpdate Event
Update properties of an existing Calendar.app event identified by its uid. Only provided fields are changed. Goes through AppleScript so changes sync to all connected accounts.
