AI agents invoke ros2_emergency_stop to trigger processes or run actions in Srv D7aoqmh5pdvs7391dcqg. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
ros2_emergency_stop can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access ros2_emergency_stop gives an agent. Each links to the full case and the policy that stops it:
Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Emergency stop a single robot via ROS2 bridge (10ms response). It is categorised as a Execute tool in the Srv D7aoqmh5pdvs7391dcqg MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Srv D7aoqmh5pdvs7391dcqg MCP server in PolicyLayer and add a rule for ros2_emergency_stop: 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 Srv D7aoqmh5pdvs7391dcqg. Nothing to install.
ros2_emergency_stop is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the ros2_emergency_stop 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.
Set action: deny in the PolicyLayer policy for ros2_emergency_stop. 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.
ros2_emergency_stop is provided by the Srv D7aoqmh5pdvs7391dcqg MCP server (ciprianpater/srv-d7aoqmh5pdvs7391dcqg). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
