WHAT IT DOES

What set_space_role_permissions does on Huly

AI agents use set_space_role_permissions to create or update resources in Huly, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Huly environment.

RISK

Why set_space_role_permissions is rated Medium

The tool modifies role definitions (a reversible Write operation) rather than deleting them. However, the blast radius is high because changing role permissions in a space affects access control for potentially many users, which could grant or revoke significant privileges. This is Write rather than Destructive because the change is reversible and the original role can be restored.

From the tool's definition Tool name and description: 'set_space_role_permissions' which 'Replace one existing role definition' — this modifies an existing role's permissions configuration.
