Drive Unreal Engine 5 from an AI agent — MCP server over the Remote Control API and in-editor Python. No C++ plugin to compile.
An MCP server that lets an AI agent drive Unreal Engine 5: create projects, import assets, build levels and Blueprints, configure replication, compile C++, run Play In Editor and package the game.
No C++ plugin to compile. It uses two plugins that already ship with the engine — Python Editor Script Plugin and Remote Control API — and talks to the editor over local HTTP.
The local layer exists because the Remote Control API only works against an editor that is already running: creating a project, launching it, compiling and packaging all have to happen at the process level.
- 72 tools and 5 resources — full reference - 278 tests, none of which need Unreal installed - Unreal automation notes — the API traps found the hard way
- Unreal Engine 5.0 or newer (developed and tested against 5.8 — see version compatibility) - Python 3.10+ - Windows, Linux or macOS. Development happens on Windows, which is where the local layer is exercised most; the Linux and macOS paths (Build.sh, RunUAT.sh, pgrep) are implemented and covered by CI, but less battle-tested. The editor layer is platform-neutral.
The server detects what the running engine supports at startup of each call — uestatus reports it under capabilities — and fails with an explicit message instead of a cryptic Python error when a feature is missing:
Feature Works on ------ Actors, levels, spawn/transform, PIE, project settings, build & packaging, Sound Cues 5.0+ Blueprint creation, components (SubobjectDataSubsystem), reparenting 5.0+ Materials, material instances, screenshots, C++ class generation 5.0+ glTF/.glb import v
