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

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

## Why blender_modifiers is rated Medium

Blender modifiers are non-destructive operations applied to 3D objects (e.g., Subdivision Surface, Boolean, Array). Based on the tool name and server context, this tool likely adds, configures, or manages modifiers on Blender objects. Modifiers in Blender are generally reversible/non-destructive, placing this in the Write category. Confidence is low due to the empty description.

From the tool's own definition: "Tool name 'blender_modifiers' combined with server description mentioning 'create, manipulate, and automate 3D scenes, objects, materials'"

## Use case

AI agents use blender_modifiers 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_modifiers": {
      "limits": [
        {
          "counter": "blender_modifiers_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
