Delete a draft
AI agents call delete_draft 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 performs an irreversible destructive action by removing draft content. While the blast radius is limited to draft messages (not sent items or permanent storage), the inability to recover deleted drafts elevates it above Write/Execute category. Destructive category applies because the action cannot be reversed and data is permanently lost.
From the tool's definition Tool name 'delete_draft' and description 'Delete a draft' explicitly indicate irreversible deletion of data. The verb 'delete' is unambiguous—it permanently removes a draft message or document without undo capability.
