## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "vrc_rename_bones",
    "arguments": {}
  }
}
```

## Why vrc_rename_bones is rated Medium

Renaming bones is a write operation—it modifies model structure reversibly. While not destructive, it could cause issues if an AI agent renames bones incorrectly, breaking rigging, animations, or VRChat avatar compatibility.

From the tool's own definition: "The tool description states it 'Rename bones from common naming schemes', which modifies existing bone naming data in the 3D model without deleting them. This is a reversible change to model metadata."

## Use case

AI agents use vrc_rename_bones to create or update resources in Blender Copilot MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Blender Copilot MCP Server environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Blender Copilot MCP Server:

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
