Revoke an API token.. Permanently disables the specified API token.
AI agents call mittwald_user_api_token_revoke to permanently remove resources in Mittwald MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly revokes/disables an API token, which cannot be undone without creating a new token. This is a destructive action that permanently removes access credentials. While not a data deletion in the traditional sense, credential revocation is irreversible and has significant security implications.
From the tool's definition Tool name and description indicate 'Revoke an API token' and 'Permanently disables the specified API token.' The use of 'Revoke' and 'Permanently disables' establishes irreversible deletion/revocation of credentials.
