WHAT IT DOES

What update_member_role does on Huly

AI agents use update_member_role 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 update_member_role is rated Medium

The tool creates or modifies data reversibly by changing a member's role assignment within a workspace. This is a Write operation (update action). Severity is 'high' because updating member roles can grant or revoke access permissions, potentially affecting multiple users' ability to view/modify workspace data, but it remains reversible (roles can be changed back).

From the tool's definition Tool name is 'update_member_role' and description states 'Update a workspace member'. This directly modifies an existing user/member record in the workspace.

update_member_role Rate-limited

update_member_role stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
