# UEFN

> Use this tool when you need to automate tasks in Unreal Editor for Fortnite or integrate AI decision-making into your workflow. The UEFN MCP Server provides a wide range of tools for actor management, asset operations, and level management, allowing AI agents to control the editor through the Model Context Protocol. It accepts HTTP requests and executes Unreal API calls, making it suitable for applications requiring automated editing, testing, or simulation in Fortnite environments.

## Description

UEFN MCP Server enables AI agents to control Unreal Editor for Fortnite through the Model Context Protocol. The server provides 28 tools across multiple domains: actor management (spawn, delete, transform, properties), asset operations (list, rename, duplicate), level management, viewport camera control, and arbitrary Python execution. The architecture uses two processes: a listener running inside UEFN's embedded Python and an external MCP server, communicating via HTTP to ensure main-thread safety for all Unreal API calls.
