Differences

This server does not require installing a new UE plugin as it uses the built-in Python remote execution protocol.

Adding new tools/features is much faster to develop since it does not require any C++ code.

It can support the full Unreal Engine Python API

Note

- This is not an official Unreal Engine project.
- Your AI agents or tools will have full access to your Editor.
- Review any changes your Client suggests before you approve them.

Installation

#### Requirements
- Unreal Engine 5.4+ (verified, may work with earlier versions)
- Node.js with npx
- MCP Client (Claude, Cursor, etc.)

1. Setting up your Editor:
- Open your Unreal Engine project
- Go to Edit -> Plugins
- Search for "Python Editor Script Plugin" and enable it
- Restart the editor if prompted
- Go to Edit -> Project Settings
- Search for "Python" and enable the "Enable Remote Execution" option

!enable plugin
!enable remote execution

2. Set up your Client:
- Edit your Claude (or Cursor) config
``json
{
"mcpServers": {
"unreal": {
"command": "npx",
"args": [

]
}
}
}
