Calendar & scheduling via LMCP

LMCP reads and writes the Mac's Calendar app (Calendar.app: local, iCloud and other accounts added to it). These tools exist only on macOS; for a Microsoft 365 calendar, use m365_list_events / m365_create_event (macOS and Windows, require connect_m365_account).

Core tools

• list_calendar_names — the user's calendars (Personal, Work, …).
• list_calendar_events — events in a date range (defaults to today + 7 days); pass event_id to read one event in full.
• create_calendar_event — new event (title, start, end, optional location/notes/calendar).
• update_calendar_event / delete_calendar_event — modify or remove an event by event_id; both take confirm and require the user's approval before applying.

Good practice

• For "am I free Tuesday?", list events for that day and report gaps.
• Always confirm the calendar + exact times before creating.
• Use ISO datetimes (e.g. 2026-07-01T10:00:00).
• Destructive ops (update/delete) are confirm-gated — show the user what will change, get approval, then call with confirm=true.
