Delete a calendar event.
AI agents call deleteCalendarEvent to permanently remove resources in Google Workspace MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes calendar event data without possibility of reversal (unless recovered through backup). Deletion is irreversible and represents data loss. While the blast radius is limited to calendar events rather than all data, this is a destructive operation.
From the tool's definition Tool name 'deleteCalendarEvent' and description 'Delete a calendar event' explicitly indicate irreversible deletion of calendar event data.
