Description

Enables programmatic creation and manipulation of Unreal Engine 5 Blueprints through a two-component architecture: a C++ plugin running inside the UE5 Editor that listens on a local TCP socket, and a Python server that translates tool calls into Blueprint manipulation commands. Supports asset management, graph manipulation, widget authoring with UMG hierarchies, Enhanced Input system generation, and Blueprint inspection queries.
