WHAT IT DOES

What room_assign does on Tolpo

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

RISK

Why room_assign is rated Medium

An AI agent can call room_assign faster than any human can review: one bad instruction and it creates or modifies resources in Tolpo by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs room_assign safely

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

room_assign Rate-limited

room_assign 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.

How do I enforce a policy on room_assign? +

What risk level is room_assign? +

room_assign is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit room_assign? +

Yes. Add a rate_limit block to the room_assign rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block room_assign completely? +

Set action: deny in the PolicyLayer policy for room_assign. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
