delete_credentials_oidc
AI agents call delete_credentials_oidc to permanently remove resources in Looker MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes OIDC (OpenID Connect) credentials from the Looker system. Credentials are security-sensitive objects, and their deletion is irreversible and cannot be undone. While not as severe as dropping database tables, credential deletion impacts authentication infrastructure and access control.
From the tool's definition Tool name 'delete_credentials_oidc' indicates irreversible deletion of OIDC credentials. The 'delete_' prefix in the context of credential management represents a destructive action that cannot be undone.
