How to control ros2_medkit_faults_clear

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_faults_clear:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "ros2_medkit_faults_clear"
  ]
}

ros2_medkit_faults_clear 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 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.
