Why segment_detected_parts needs a policy

The description is empty and uninformative. Based on the tool name and server context (Live2D model generation pipeline), this tool likely performs image segmentation of detected body/face parts from a photo — a read/processing operation with no destructive side effects.

POLICY

How to control segment_detected_parts

PolicyLayer is an MCP gateway — it sits between your AI agents and Live2D Automation MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for segment_detected_parts:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "segment_detected_parts": {
      "limits": [
        {
          "counter": "segment_detected_parts_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

segment_detected_parts gets a rate cap, and everything else on the server is denied unless you say otherwise.
