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

```json
{
  "jsonrpc": "2.0",

## Why blender_mesh is rated Medium

The description is empty, so classification relies on context. 'blender_mesh' most likely creates or modifies mesh objects in Blender (a 3D modeling operation), which is a Write operation. It could also be Execute if it runs arbitrary mesh operations.

From the tool's own definition: "Tool name 'blender_mesh' on a server for controlling Blender to create, manipulate, and automate 3D scenes and objects."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "blender_mesh": {
      "limits": [
        {
          "counter": "blender_mesh_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
