maya-mcp 0.4.0

MCP server for controlling Autodesk Maya via commandPort

Maya MCP

Maya MCP is a local Model Context Protocol server for controlling Autodesk Maya through Maya's commandPort.

It gives MCP clients a typed tool surface for scene work, nodes, selection, modeling, shading, skinning, animation, curves, scripts, and viewport capture without importing Maya modules in the server process.

This project is unofficial and is not affiliated with or endorsed by Autodesk. Autodesk Maya is a trademark of Autodesk, Inc.

Why Use It

• runs outside Maya, so the server stays isolated from Maya imports
• talks to Maya over localhost only
• exposes 71 typed tools instead of raw API calls
• supports safer scene replacement flows for unsaved changes
• leaves raw code execution disabled unless you opt in

Quick Start

1. Install

pip install maya-mcp

From source:

pip install -e ".[dev]"

2. Open Maya commandPort

Run this in Maya's Script Editor on the Python tab:

import maya.cmds as cmds

try:
    cmds.commandPort(name=":7001", close=True)
except RuntimeError:
    pass

cmds.commandPort(
    name=":7001",
    sourceType="python",
    echoOutput=True,
    noreturn=False,
    bufferSize=16384,
)

3. Start the server

maya-mcp

Other supported launch styles:

python -m maya_mcp.server
python src/maya_mcp/server.py
fastmcp run

fastmcp run works from this repo because it includes fastmcp.json.

4. Add it to your client

Minimal generic config:

{
  "command": "maya-mcp"
}

VS Code workspace example in .vscode/mcp.json:

{
  "servers": {
    "maya": {
      "type": "stdio",
      "command": "maya-mcp"
    }
  }
}

5. Verify

Call these tools in order:

1. health.check
2. scene.info
3. nodes.list

Tool Coverage

Family	Count
health	1
maya	2
scene	9
nodes	7
attributes	2
selection	6
connections	5
mesh	3
viewport	1
modeling	15
shading	3
skin	6
animation	6
curve	2
script	3

script.run is disabled by default and requires MAYA_MCP_ENABLE_RAW_EXECUTION=true.

scene.new and scene.open still refuse by default when the current scene has unsaved changes. Clients that advertise MCP form elicitation can receive an in-band discard-changes confirmation instead of having to retry with force=True.

Development

This repo uses py for Python commands on Windows:

py -m ruff check .
py -m ruff format .
py -m mypy src/
py -m pytest

If tests import maya_mcp from site-packages instead of this repo:

$env:PYTHONPATH='src'
py -m pytest

Security Notes

• localhost only
• no remote-host support
• no Maya imports in the MCP server process
• no arbitrary code execution by default
• no secrets or raw tracebacks in client-facing errors
