How do I install Unreal?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Unreal need an API key?

No required environment variable is listed on this record.

What transport does Unreal use?

Unreal runs locally over stdio.

Unreal MCP 服务器

MCP server for Unreal Engine that uses Unreal Python Remote Execution

⚡ 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.)

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

Set up your Client:
- Edit your Claude (or Cursor) config

{
  "mcpServers": {
    "unreal": {
      "command": "npx",
      "args": [
        "-y",
        "@runreal/unreal-mcp"
      ]
    }
  }
}

🔧 Troubleshooting

If you get an error similar to MCP Unreal: Unexpected token 'C', Connection... it means that the mcp-server was not able to connect to the Unreal Editor.

Make sure that the Python Editor Script Plugin is enabled and that the Remote Execution option is checked in your project settings.
Try also changing your bind address from 127.0.0.1 to 0.0.0.0 but note that this will allow connections from your local network.
Restart your Unreal Editor fully.
Fully close/open your client (Claude, Cursor, etc.) to ensure it reconnects to the MCP server. (File -> Exit on windows).
Check your running processes and kill any zombie unreal-mcp Node.js processes.
