The Unreal Engine MCP Server for Claude Desktop is a Python-based server that connects Claude Desktop with Unreal Engine 5.3, allowing users to create and manipulate 3D scenes through text prompts. This integration represents a significant step toward automating 3D scene generation and manipulation using natural language processing.
What are the system requirements for running the Unreal Engine MCP Server?
You need Python 3.10+, Unreal Engine 5.3 with the Remote Control API plugin enabled, and Claude Desktop on Windows.
How do I troubleshoot connection issues?
Ensure Unreal Engine is running before starting the MCP server, the Remote Control API plugin is enabled, no other process is using port 30010, and your firewall is not blocking the connection.
What should I do if objects are not appearing in Unreal Engine?
Check the output log in Unreal Engine for errors, ensure objects are not created too far from the origin, and simplify requests to isolate issues.
Can I contribute to the Unreal Engine MCP Server project?
Yes, contributions are welcome, especially in areas like natural language processing, complex object creation, and supporting more Unreal Engine features.
What types of objects can I create with this server?
You can create primitive shapes like cubes, spheres, cylinders, planes, and cones, as well as spawn actors from Blueprint classes.
