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

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

## Why uv_add_layer is rated Medium

This tool creates a new UV layer (a new data structure within a 3D object) without deleting or overwriting existing layers. UV layers are essential for texture mapping in 3D models. The operation is reversible (the layer can be deleted), modifying object properties rather than executing arbitrary code or performing destructive operations.

From the tool's own definition: "uv_add_layer: 'Add a new UV layer to an object.' — creates/adds a new UV layer, which is a reversible modification to the object's UV mapping data."

## Use case

AI agents use uv_add_layer 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)

## 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`
