Untrusted display-only summary

Deletes a specified event by `event_id` from a Google Calendar (`calendar_id`); idempotent — a 404 for an already-deleted event is a no-op. Bulk deletions may trigger `rateLimitExceeded` or `userRateLimitExceeded`; cap concurrency to 5–10 requests and apply exponential backoff.

Untrusted display-only summary

Creates a new, empty Google Calendar with the specified title (summary). Newly created calendars default to UTC timezone; use GOOGLECALENDAR_PATCH_CALENDAR afterward to set the desired timeZone if needed.

Untrusted display-only summary

Retrieves a SINGLE event by its unique event_id (REQUIRED). This action does NOT list or search events - it fetches ONE specific event when you already know its ID. If you want to list events within a time range, search for events, or filter by criteria like time_min/time_max, use GOOGLECALENDAR_EVENTS_LIST instead.

Untrusted display-only summary

Tool to import an event as a private copy to a calendar. Use when you need to add an existing event to a calendar using its iCalUID. Only events with eventType='default' can be imported.

Untrusted display-only summary

Returns instances of the specified recurring event. Use timeMin/timeMax to constrain the window; omitting bounds can return large result sets and is quota-heavy. On high-volume calls, 403 rateLimitExceeded or 429 too_many_requests may occur; apply exponential backoff (1s, 2s, 4s) before retrying.

Untrusted display-only summary

Returns events on the specified calendar. TIMEZONE WARNING: When using timeMin/timeMax with UTC timestamps (ending in 'Z'), the time window is interpreted in UTC regardless of the calendar's timezone. For example, querying '2026-01-19T00:00:00Z' to '2026-01-20T00:00:00Z' on a calendar in America/Los_Angeles (UTC-8) co…

Untrusted display-only summary

Return a unified event list across all calendars in the user's calendar list for a given time range. Use when you need a single view of all events across multiple calendars. An inverted or incorrect time range silently returns empty results rather than an error. An empty `items` list means no events matched the filter…

Untrusted display-only summary

Moves an event to another calendar, i.e., changes an event's organizer.

Untrusted display-only summary

Watch for changes to Events resources. Watch channels expire; persist the channel `id` per `calendarId` to re-establish watches after expiration or restarts.
