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

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

## Why clear_scene is rated Critical

This tool permanently removes all objects from a Blender scene, which is an irreversible operation that cannot be undone by normal means (beyond undo history). While not as catastrophic as deleting files from disk, clearing an entire scene represents a destructive action with significant blast radius—an AI agent could lose hours of 3D work.

From the tool's own definition: "Tool name 'clear_scene' and description 'Remove all objects from the current scene' indicate irreversible deletion of scene content."

## Use case

AI agents call clear_scene to permanently remove resources in Blender, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "clear_scene"
  ]
}
