WHAT IT DOES

What gcp_sql_delete_user does on GCP MCP Server

AI agents call gcp_sql_delete_user to permanently remove resources in GCP MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why gcp_sql_delete_user is rated Critical

Deletion of database users cannot be undone and will break authentication and access for that user immediately. This is a destructive action with potential to disrupt production systems and cause data access loss. While not as severe as deleting data itself, user deletion is irreversible and has significant blast radius in a Cloud SQL environment.

From the tool's definition Tool name contains 'delete' and description states 'Delete a user from a Cloud SQL instance' — this is an irreversible removal of a database user account.
