Unreal MCP

Control Unreal Engine in natural language

Runs as a server Claude Code connects to. It needs its own configuration, and some servers need an API key.

Install just this one

Run in your terminal — needs Node

npx archtmpl@latest --mcp unreal-mcp

First time? The whole install, step by step

Open Claude Code — the terminal version or the desktop app, either one.
In a terminal, paste the line above and press Enter. In the app, paste it into the chat and ask Claude to run it.
Restart Claude Code. That's the whole install.

Requires Unreal Engine 5.5+ and Python 3.12+. Marked experimental by the project author — expect breaking changes."
