Unreal Engine function inspector MCP server

Prerequisites

You need the API endpoint and API key. Contact the owner.

Support all platforms where the modern python (3.9+) and uv (popular python package manager) can run.

It's tested extensively with Claude Desktop App. Should also work with Cursor and other MCP clients.

Setting up environment

Install Python 3.9+ (it was tested on 3.12–3.13) from the official site. If you are on Windows, DO NOT install it from the Windows App Store!

Install uv package manager: https://docs.astral.sh/uv/getting-started/installation/

Run uv sync to create the virtual env in this directory.

Create an .env file by copying the .env.example.

Set the BACKEND_URL (API endpoint) and BACKEND_API_KEY

Run uv run mcp dev ue_mcp_server.py to bring up the MCP inspector, where you can smoke-test all the tools.

Deploy

Add this blob in your Claude Desktop MCP configuration:

This config file is typically %APPDATA%/Claude/claude_desktop_config.json. Find or create a section mcpServers
