ue5-mcp-bridge

Overview

This MCP server provides a comprehensive bridge between AI assistants and Unreal Engine 5, allowing developers to interact with their projects through natural language commands. It supports manipulation of levels, actors, Blueprints, Animation Blueprints, materials, and other game assets. The server implements the standard Model Context Protocol and works with multiple AI clients including Claude Desktop, OpenAI ChatGPT Desktop, Cursor, and others. Originally part of the UnrealClaude plugin, it has been moved to a standalone repository to support broader MCP adoption and community contributions.

FAQ

What AI clients are compatible with this MCP server?

This server works with any MCP-compatible AI client including Claude Code, Claude Desktop App, OpenAI ChatGPT Desktop, Cursor, Replit, Sourcegraph Cody, Windsurf, and other MCP-compliant tools.

Is this a 'text-to-game' tool that generates assets automatically?

No, this is NOT a 'text-to-game' tool. It's a workflow accelerator for Unreal Engine developers that helps with repetitive tasks, project setup, and rapid prototyping, but does not replace the work of artists, animators, and asset creators.

What are the system requirements?

Node.js 18.0.0 or higher and an HTTP endpoint that implements the expected REST API (default: http://localhost:3000). The server is designed to work with the UnrealClaude plugin but can be adapted for other HTTP backends that implement the same API.
