Why conversational_blender_assistant needs a policy

The description is empty, providing no information about what this tool actually does. The name suggests a conversational interface, which could be read-only (answering questions) or could trigger other operations. Given the sibling tools on this server (which include execute, write, and destructive operations), this assistant could potentially orchestrate any of them, but without evidence we cannot assume the worst.

From the tool's definition Tool name is 'conversational_blender_assistant' with empty description.

POLICY

How to control conversational_blender_assistant

PolicyLayer is an MCP gateway — it sits between your AI agents and Blender, and nothing reaches the server without passing your rules. This is the rule we recommend for conversational_blender_assistant:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "conversational_blender_assistant": {
      "limits": [
        {
          "counter": "conversational_blender_assistant_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

conversational_blender_assistant gets a rate cap, and everything else on the server is denied unless you say otherwise.

Create a free account and register Blender — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
