Documentation Overview

UnrealMCP — AI Bridge for Unreal Engine 5

Control the Unreal Engine 5 editor from Claude Code, Cursor, Windsurf, or any MCP client. Build materials, wire Blueprint graphs, author Niagara systems, spawn actors, edit data tables and profile performance, all by asking for it. 288 commands across 15 categories, no leaving your terminal.

This is the community edition

It is stable and feature complete for what it covers. It is not abandoned, and it is not in active development either: new subsystem work now goes into CodeFizz Editor Agent, the maintained commercial build. Everything here keeps working, issues still get read, and the MIT licence is permanent.

If you want Control Rig, PCG, Sequencer, Mutable, Procedural Vegetation, audio and MetaSounds, Behavior Trees and EQS, or packaged binaries for UE 5.6 / 5.7 / 5.8, that lives in Pro.

Already on UE 5.8? Epic now ships a first-party MCP server in 5.8 (Experimental, localhost only). It is worth trying before you buy anything. This repo and Pro both also cover 5.6 and 5.7, which Epic's does not.

Two ways to use this repo

	CLI	MCP Server
Install	`npm install -g unrealcli`	`pip install unrealmcp`
Dependencies	None (single binary)	Python 3.10+
Works with	Claude Code (via Bash)	Claude Code, Cursor, Windsurf, VS Code, Gemini CLI, Rider, Zed, Amazon Q
Protocol	Direct TCP	MCP over stdio

Both talk to the same C++ plugin inside the editor. Use whichever fits your workflow, or both.

Quick Start

Option A: CLI (Recommended for Claude Code)

bash

# 1. Install
npm install -g unrealcli

# 2. Go to any UE5 project and install the plugin
cd YourProject/
ue-cli init

# 3. Open the editor, then verify
ue-cli health_check

That's it. No Python, no config files, no MCP setup.

Option B: MCP Server (For Cursor, Windsurf, etc.)

bash

# 1. Clone the plugin into your project
git clone https://github.com/aadeshrao123/Unreal-MCP.git Plugins/UnrealMCP

# 2. Install the Python MCP server
pip install unrealmcp

# 3. Add to your AI tool's config (see MCP Setup section below)
