Remove a contact
AI agents call deletePeopleContactPhoto 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.
The tool permanently removes contact information (photo and associated contact record), which is an irreversible destructive operation. While not as severe as deleting shared business documents, it permanently removes user data that cannot be recovered through normal means. This qualifies as Destructive rather than Write because deletion is irreversible.
From the tool's definition Tool name 'deletePeopleContactPhoto' contains 'delete' and performs 'Remove a contact', which irreversibly deletes contact data from Google Workspace.
