scale_object

What scale_object does on BlenderMCP

AI agents invoke scale_object to trigger actions in BlenderMCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

Why scale_object is rated High

While scaling is reversible (unlike deletion), it is an Execute-category action because it triggers a transformation operation in Blender whose outcome depends on supplied parameters. It is not Read (has side effects), not Write (modifies geometry rather than creating structured data), not Destructive (reversible), not Financial, and not Other.

From the tool's definition The tool 'scale_object' modifies 3D objects in Blender by changing their dimensions. As part of a suite that includes 'execute_blender_code' and 'render_scene', it performs an operation whose effects depend on arguments (object selection, scale factors).

The rule that runs scale_object safely

PolicyLayer is an MCP gateway: it sits between your AI agents and BlenderMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For scale_object, this is the rule to start with:

{
  "version": "1",
  "default": "deny",
  "tools": {
    "scale_object": {
      "limits": [
        {
          "counter": "scale_object_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
