Hey everyone! ![]()
I wanted to share a project I’ve been building that I think a lot of UE5 developers will find useful — VibeUE, a free, open-source MCP (Model Context Protocol) server that connects AI coding tools directly to the live Unreal Editor.
VibeUE has been in active development for 6 months, live on FAB for 3, and has been shaped from day one by community feedback. It lets you use AI to understand, explain, and modify your Unreal Engine projects through natural conversation — Blueprints, materials, landscapes, widgets, animation, audio, StateTrees, and more.
It works two ways:
-
In-Editor AI Chat — A built-in chat panel right inside UE5. No external tools needed. Free API key available at vibeue.com.
-
External MCP Connection — Hook up Claude Desktop, VS Code, Cursor, or any MCP-compatible AI tool to drive Unreal from your IDE.
What can it actually do?
-
26 specialized Python API services covering 866+ methods across Blueprints, Niagara, materials, terrain, animation, audio, widgets, StateTrees, foliage, and more
-
10 MCP tools for asset workflows, debugging, graph editing, terrain generation, and real-world heightmap data
-
28 lazy-loaded domain skills so the AI actually knows what it’s doing inside UE
-
Real-world terrain generation from GPS coordinates
-
Full access to the Unreal Engine Python API — if UE can do it in Python, VibeUE can do it
Community-driven and looking for contributors ![]()
VibeUE isn’t a corporate product — it’s built by developers, for developers, and the community has been a huge part of getting it to where it is today. Whether you want to add new Python service coverage, improve MCP tools, help with docs, or just report bugs and share ideas — all contributions are welcome. The project is MIT licensed and fully open on GitHub.
Come hang out in the Discord if you have questions, want to show off what you’ve built, or want to get involved in shaping the roadmap.
Happy to answer any questions — let me know what you think! ![]()
