WHAT IT DOES

What custom_remove_user_roles does on Marketo MCP Server

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

RISK

Why custom_remove_user_roles is rated Critical

Removing user roles is a destructive action that cannot be easily undone without administrative intervention. It permanently revokes access and permissions, affecting system security and user workflows. While the description is empty (lowering confidence slightly), the name itself clearly indicates a destructive operation on access control.

From the tool's definition Tool name 'custom_remove_user_roles' indicates removal/deletion of role assignments. The verb 'remove' combined with 'user_roles' in a system management context implies irreversible deletion of access permissions.
