Initial release.
UEMCP is an open source MCP server that lets Claude drive a live Unreal Engine 5 editor over the engine's built-in Python remote execution protocol. Nothing to compile or install inside Unreal: enable the Python Editor Script Plugin, check Enable Remote Execution, done.
Highlights
- 31 tools: actors, assets, materials, blueprints, levels, viewport camera, screenshots returned as images, simulate control, console commands, and a raw Python escape hatch
- Self-healing connection that survives editor restarts
- Structured JSON results with real in-editor Python tracebacks on failure
- Works with UE 5.0 through 5.6, Launcher and source builds
- 87 tests that run without Unreal; CI on Ubuntu and Windows
