Unreal Python MCP

Setup

1. Enable 'Python Editor Script Plugin' in Unreal Editor
2. Enable 'Edit' → 'Project Settings' → 'Plugins' → 'Python' → 'Enable Remote Execution' & 'Develop Mode'
3. Restart Unreal Editor and keep it running
4. Add mcp config:

   {
     "mcpServers": {
       "unreal-python-mcp": {
         "command": "npx",
         "args": ["-y", "unreal-python-mcp"]
       }
     }
   }

5. Enjoy it!

If your mcp client does not support auto install node packages, you can run npm install --save-dev unreal-python-mcp in your workspace

Configuration (Optional)

You can customize the remote execution connection via environment variables:

| Environment Variable | Description | Default | | ------------------------ | ----------------------- | ----------- | | UNREAL_MULTICAST_GROUP | Multicast group address | 239.0.0.1 | | UNREAL_MULTICAST_PORT | Multicast port | 6766 | | UNREAL_BIND_ADDRESS | Bind address | 127.0.0.1 |

Example with custom configuration:

{
  "mcpServers": {
    "unreal-python-mcp": {
      "command": "npx",
      "args": ["-y", "unreal-python-mcp"],
      "env": {
        "UNREAL_BIND_ADDRESS": "0.0.0.0"
      }
    }
  }
}
