Google Calendar: Move an event to another calendar — MCP tool

Google Calendar MCP tool: Moves an event from one calendar to another without changing its time.

Technical name: move_event

What task it solves

I want to move this event onto a different calendar.

Moves the event to the destination calendar (its organizer calendar changes; the event id stays the same) and returns the moved event.

When to use it

Use it to re-home an event — e.g. from a personal calendar to a team calendar. Rescheduling to another TIME is update_event, not this.

What to provide

• calendar_id — required. The calendar the event is on now.
• event_id — required.
• destination_calendar_id — required. The target calendar (from list_calendars).
• send_updates — optional. all notifies the guests about the move.

What it returns

The moved event as compact JSON.

What changes in Google Calendar

The event disappears from the source calendar and appears on the destination calendar. Guests keep their invitations; the organizer calendar changes.

Example request

Move the quarterly planning event from my calendar to the team calendar.

Errors and limitations

Only regular events can move — Out of Office, Focus Time, working-location and birthday events cannot. An event with attendees can be moved only by its organizer. Needs writer access to BOTH calendars. Replaying the same move converges (the event is already there), but verify with get_event after an ambiguous failure.

Access also depends on token permissions, quotas, and upstream API limits.
