nwo_send_ros2_action · NWO Robotics MCP: Risk & Policy

WHAT IT DOES

What nwo_send_ros2_action does on NWO Robotics

AI agents invoke nwo_send_ros2_action to trigger actions in NWO Robotics. 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 nwo_send_ros2_action needs a policy

This tool sends commands directly to a physical ROS2 robot system. Executing arbitrary actions on real robots can have significant physical-world consequences including equipment damage, safety hazards, or unintended physical operations. It triggers external operations on physical hardware, placing it firmly in the Execute category with critical severity due to the potential for real-world harm.

Verdict

nwo_send_ros2_action Rate-limited

nwo_send_ros2_action 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.

FAQ

Questions about nwo_send_ros2_action

What does the nwo_send_ros2_action tool do? +

Send action directly to ROS2 robot through the bridge. It is categorised as a Execute tool in the NWO Robotics MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on nwo_send_ros2_action? +

Register the NWO Robotics MCP server in PolicyLayer and add a rule for nwo_send_ros2_action: 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 NWO Robotics. Nothing to install.

What risk level is nwo_send_ros2_action? +

nwo_send_ros2_action is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit nwo_send_ros2_action? +

Yes. Add a rate_limit block to the nwo_send_ros2_action 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 nwo_send_ros2_action completely? +

Set action: deny in the PolicyLayer policy for nwo_send_ros2_action. 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 nwo_send_ros2_action? +

nwo_send_ros2_action is provided by the NWO Robotics MCP server (redciprianpater/mcp-server-robotics). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
