Why execute_maya_code needs a policy

This tool directly executes Maya code/scripts with no predetermined constraints. Given the server's purpose is to translate natural language into Maya operations, an AI agent could be manipulated into executing malicious or unintended Maya code affecting the 3D scene, file system, or external systems. The empty description increases risk by preventing validation of intended behavior.

From the tool's definition Tool name 'execute_maya_code' indicates arbitrary code execution capability; combined with server description enabling 'object creation, transformation, material application, and more' through AI commands, this tool permits running arbitrary Maya…

POLICY

How to control execute_maya_code

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

policy.json

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

execute_maya_code stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

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