Delete a calendar event.
AI agents call gcal_delete_event to permanently remove resources in Integrations MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a calendar event is an irreversible action that cannot be undone. Once deleted, the event is permanently removed from the user's Google Calendar unless restored from a backup. This fits the Destructive category (irreversibly deletes data).
From the tool's definition Tool name 'gcal_delete_event' and description 'Delete a calendar event' explicitly indicate permanent removal of calendar data with no recovery mechanism.
