WHAT IT DOES

What transkribus_coll_user_add_or_modify does on Transkribus

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

RISK

Why transkribus_coll_user_add_or_modify is rated Medium

This tool modifies collection membership and user roles, which are data-state changes that can be reversed (users can be removed or roles changed back). It does not delete data, execute code, move money, or trigger irreversible actions. The blast radius is medium because an AI misusing this could grant unauthorized access to collections, but access can be revoked.

From the tool's definition Tool name includes 'add_or_modify' and description states 'Add a user to a collection or modify their role' — both are reversible write operations that create or update user access.

RECOMMENDED RULE

The rule that runs transkribus_coll_user_add_or_modify safely

transkribus_coll_user_add_or_modify Rate-limited

transkribus_coll_user_add_or_modify 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.
