Why ros2_medkit_area_components needs a policy

This tool queries and returns information about ROS 2 system components grouped by area. It performs discovery/introspection only, similar to the recommended prerequisite ros2_medkit_areas_list. No data is modified, deleted, executed, or used for financial transactions. The blast radius of misuse is minimal—an agent could only retrieve unwanted information about system topology.

From the tool's definition Tool name includes 'list' and description states 'List all components within a specific area' — a pure data retrieval operation with no side effects.

POLICY

How to control ros2_medkit_area_components

PolicyLayer is an MCP gateway — it sits between your AI agents and Ros2 Medkit, and nothing reaches the server without passing your rules. This is the rule we recommend for ros2_medkit_area_components:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "ros2_medkit_area_components": {}
  }
}

ros2_medkit_area_components is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Ros2 Medkit — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
