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

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

## Why create_glass is rated Medium

This tool creates or modifies material attributes on a Blender object. While it alters the 3D scene state, the change is reversible (materials can be changed or removed), so it falls under Write rather than Destructive. The severity is medium because misuse could degrade a complex scene's appearance or apply unwanted materials to many objects, but the effect is easily undone.

From the tool's own definition: "Tool name 'create_glass' and description 'Apply a glass/transparent material to an object' indicate the tool modifies object material properties in Blender, which is a reversible change to scene data."

## Use case

AI agents use create_glass 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:

```json
