clean_all_ros2_nodes

THE RISK

Critical Risk

This tool terminates all running ROS 2 and Gazebo processes simultaneously. This is irreversible — killed processes cannot be restored to their prior state, and any unsaved robot state, sensor data, or simulation progress is lost. The blast radius is critical because misuse would immediately halt all robot operations and simulations in the environment, potentially causing physical robot issues in real deployments.

From the tool's definition Kills all currently running ROS 2 and Gazebo related processes to clean the environment

HOW TO CONTROL CLEAN_ALL_ROS2_NODES

PolicyLayer is an MCP gateway — it sits between your AI agents and ROS MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for clean_all_ros2_nodes:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "clean_all_ros2_nodes"
  ]
}

clean_all_ros2_nodes disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register ROS MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

What does the clean_all_ros2_nodes tool do? +

Kills all currently running ROS 2 and Gazebo related processes to clean the environment. It is categorised as a Destructive tool in the ROS MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on clean_all_ros2_nodes? +

Register the ROS MCP server in PolicyLayer and add a rule for clean_all_ros2_nodes: 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 MCP. Nothing to install.

What risk level is clean_all_ros2_nodes? +

clean_all_ros2_nodes is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit clean_all_ros2_nodes? +

Yes. Add a rate_limit block to the clean_all_ros2_nodes 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 clean_all_ros2_nodes completely? +

Set action: deny in the PolicyLayer policy for clean_all_ros2_nodes. 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 clean_all_ros2_nodes? +

clean_all_ros2_nodes is provided by the ROS MCP server (yutarop/ros-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every ROS MCP tool call.
