Delete a contact group. Contacts in the group are not deleted.
AI agents call deletePeopleContactGroup 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 performs an irreversible deletion operation on a contacts group. Even though individual contacts are preserved, the group itself is permanently removed with no undo capability. This meets the Destructive category definition of irreversibly deleting data.
From the tool's definition Tool name explicitly states 'delete' and description confirms 'Delete a contact group'. This is an irreversible operation that removes data (the group structure itself, though not the individual contacts within it).
