Remove user from n8n instance. Only available to instance owner. Cannot delete the owner account. Deleted users lose access immediately. Workflows created by this user remain intact.
AI agents call n8n_delete_user to permanently remove resources in n8n Management MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool performs irreversible deletion of user accounts from the n8n instance. While not data destruction in the traditional sense, account deletion is a destructive action that cannot be reversed without administrative intervention (user recreation). The blast radius is significant: deleted users lose all access and authentication credentials are eliminated.
From the tool's definition Tool name and description: 'Remove user from n8n instance' - this irreversibly deletes a user account and revokes all access. The description explicitly states 'Deleted users lose access immediately,' indicating an irreversible action that cannot be undone.
