VibeUE

Why we included this project

VibeUE is a plugin that extends Unreal Engine 5.8's built-in MCP server, letting an AI agent do more inside the editor without a separate server or an in-editor chat. It registers extra editor capabilities, from landscape sculpting and foliage to audio graphs, Niagara, and behavior trees, into the engine's own toolset registry, so an agent like Claude Code or Cursor can drive them through Unreal's standard protocol. The profiling piece stands out: an agent can capture Unreal Insights traces and report whether a frame is CPU- or GPU-bound, which is genuinely useful when you're chasing frame-rate problems. Real-world terrain generation from GPS data is included too, though that part needs a free API key. You do need Unreal's native MCP plugin enabled first, but once that's set up, VibeUE is a straightforward way for solo developers and small teams to hand off repetitive editor work and block out levels faster.
