WHAT IT DOES

What crow_remove_member does on Crow

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

RISK

Why crow_remove_member is rated Medium

The tool revokes a member's access by setting a revoked_at timestamp rather than deleting the record, making it a reversible write operation. However, the blast radius is high because revoking a member removes their access to the project space, which could disrupt collaboration and lock out legitimate users if misused.

From the tool's definition Soft-revoke a member from a project space (sets revoked_at; does not delete the row)

RECOMMENDED RULE

The rule that runs crow_remove_member safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Crow, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For crow_remove_member, this is the rule to start with:

crow_remove_member Rate-limited

crow_remove_member 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.
