# VibeUE

> VibeUE is the open-source MCP (Model Context Protocol) server for Unreal Engine 5. It enables AI assistants like Claude, GitHub Copilot, Cursor, and other MCP-compatible tools to directly control and interact with Unreal Engine through Python APIs.

## What is VibeUE?

VibeUE brings AI-powered "vibe coding" to Unreal Engine development. It provides:

- **10 MCP Tools** for API discovery, Python code execution, asset management, terrain data, screenshots, and web research
- **26 Python Services** with 866+ methods covering Blueprints, materials, landscapes, animation, audio, widgets, Niagara VFX, skeletons, StateTree AI behavior, Enhanced Input, foliage, gameplay tags, data assets, data tables, enums/structs, level actors, project settings, engine settings, and more
- **In-Editor AI Chat** built into Unreal Engine — no external tools needed
- **External MCP Connection** for VS Code, Claude Desktop, Cursor, and AntiGravity
- **28 Domain Skills** for specialized workflows (animation, terrain, materials, Niagara, gameplay tags, etc.)
