UnrealMotionGraphicsMCP

Overview

UE5-UMG-MCP is an MCP server designed to maximize AI efficiency when working with Unreal Engine's UMG UI system. It enables programmatic interaction with UMG assets through a comprehensive API, allowing developers and designers to version control UI elements in Git via JSON representations. The server bridges the gap between AI assistants and Unreal Engine's visual UI editor, providing tools for querying, modifying, and exporting UMG layouts and blueprints.
