What is Unreal Engine MCP Server for Claude Desktop?

An MCP server that lets Claude Desktop interact with Unreal Engine 5.3 via its Remote Control API. It enables creating and manipulating 3D objects in Unreal Editor from natural language prompts, serving as an early step toward text-to-game generation.

How to use Unreal Engine MCP Server for Claude Desktop?

Requires Python 3.10+, Unreal Engine 5.3 with Remote Control API plugin enabled. Clone the repo, run pip install -e ., then configure claude_desktop_config.json with the uv command pointing to unreal_mcp_server.py. Launch Unreal Engine and restart Claude Desktop to connect. Use prompts like “Create a red cube at position 100, 200, 50” to issue commands.

Key features of Unreal Engine MCP Server for Claude Desktop

  • Create and modify primitive shapes (cube, sphere, cylinder, etc.)
  • Spawn actors from Blueprint classes
  • Manipulate object position, rotation, scale, color, and visibility
  • List and select actors in the current level
  • Save levels and inspect editor selection
  • Call arbitrary Unreal Remote Control functions and read/write properties
  • Direct CLI (unreal-mcp-cli) for non-MCP agents
  • Built‑in castle workflow with verification and reset tools

Use cases of Unreal Engine MCP Server for Claude Desktop

  • Building 3D scenes from text descriptions in Unreal Engine

  • Automating repetitive editor tasks (placement, color changes, level saving)
  • Querying and manipulating Unreal project assets and actors through chat

常见问题

1

What are the requirements?

Python 3.10+ and Unreal Engine 5.3 with the Remote Control API plugin enabled.

2

How do I configure the server for Claude Desktop?

Add an entry to `claude_desktop_config.json` with the command `uv` and args pointing to the server script, then restart Claude Desktop.

3

What if objects aren’t appearing in the scene?

Check the Unreal output log for errors. Ensure objects aren’t placed too far from the origin (0,0,0) and simplify your request to isolate issues.

4

How can I run the server in development mode?

Install `mcp[cli]` and use `mcp dev unreal_mcp_server.py` to run the server in development mode.

5

How do I test connectivity?

Ask Claude to create an object in Unreal Engine. If the server is connected correctly, the object should appear in the editor.
