Overview

What is Unreal MCP?

Unreal MCP is a Model Context Protocol bridge for Unreal Engine 5 that enables AI assistants to control the editor through over 100 tools. It is designed for game developers using UE5 who want to leverage AI coding assistants like Claude Code, Cursor, or GitHub Copilot to automate editor tasks.

How to use Unreal MCP?

Install the Python package via pip install unrealmcp, then add the server to your AI tool’s MCP configuration with "command": "unrealmcp". The server automatically discovers a running UE5 editor instance via a port file—no manual paths, tokens, or Docker setup are required.

Key features of Unreal MCP

  • 100+ editor tools covering materials, blueprints, actors, data tables, widgets, enhanced input, and profiling
  • Built-in support for 8 AI assistants: Claude Code, Cursor, VS Code/Copilot, Gemini CLI, Windsurf, JetBrains/Rider, Zed, and Amazon Q
  • Zero configuration: simply specify "command": "unrealmcp" in your MCP config
  • Auto-discovers the running UE5 editor via a port file—no manual port mapping
  • Tested on Unreal Engine 5.7, likely works on earlier 5.x versions

Use cases of Unreal MCP

  • Create and compile Blueprints, add components, variables, functions, and graph nodes via AI prompts
  • Build and apply material node graphs, create material instances, and assign them to actors
  • Spawn, transform, and delete actors; get and set their properties programmatically
  • Manage data tables (schema, add/update/delete rows) and data assets (create, read/write properties)
  • Start/stop profiling traces, diagnose bottlenecks, and review flame charts and frame analysis

Frequently asked questions

1

Which AI tools are supported?

The server supports Claude Code, Cursor, VS Code/Copilot, Gemini CLI, Windsurf, JetBrains/Rider, Zed, and Amazon Q.

2

How does Unreal MCP connect to the Unreal Engine editor?

A C++ plugin runs inside the UE5 editor as a TCP server. The Python MCP server translates AI tool calls into TCP commands. The server auto-discovers the editor via a port file, so no manual port configuration is needed.

3

Which Unreal Engine versions are compatible?

The bridge has been tested on Unreal Engine 5.7 and may work on earlier 5.x versions.

4

Do I need to install any additional plugins or dependencies?

The `unrealmcp` package handles the MCP side; a C++ plugin runs inside the UE5 editor. No additional tokens, paths, or Docker setup are required.

5

Can I use Unreal MCP without configuring ports?

Yes. The server auto-discovers the running editor via a port file, eliminating the need for manual port configuration.
