request_plan_route · Ros MCP: Risk & Policy

WHAT IT DOES

What request_plan_route does on Ros

AI agents invoke request_plan_route to trigger actions in Ros. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why request_plan_route needs a policy

This tool sends a routing/planning command to a physical robot system. While it may only compute a route rather than physically move the robot, it dispatches an external operation to an AMR control system. In the context of a robot control server with sibling tools like navigate_to_poses and send_motion_command, a plan_route request triggers real external system operations.

From the tool's definition 'Dispatch a plan_route request and wait for the response' — triggers an external operation on an Autonomous Mobile Robot via MQTT

Verdict

request_plan_route Rate-limited

request_plan_route stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Ros, so you can run agents against it safely.

FAQ

Questions about request_plan_route

What does the request_plan_route tool do? +

Dispatch a plan_route request and wait for the response. It is categorised as a Execute tool in the Ros MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on request_plan_route? +

Register the Ros MCP server in PolicyLayer and add a rule for request_plan_route: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Ros. Nothing to install.

What risk level is request_plan_route? +

request_plan_route is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit request_plan_route? +

Yes. Add a rate_limit block to the request_plan_route 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 request_plan_route completely? +

Set action: deny in the PolicyLayer policy for request_plan_route. 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.

What MCP server provides request_plan_route? +

request_plan_route is provided by the Ros MCP server (reidlo5135/ros-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
