Introducing unreal-mcp-ue4

An introduction to a UE4.27.2-focused MCP server built around Unreal Python Remote Execution and practical editor workflows.

unreal-mcp-ue4 is a UE4.27.2-focused MCP server for Unreal Engine built around Unreal Python Remote Execution.

The project started from the core idea and early workflow shape of runreal/unreal-mcp, but it has since been refactored heavily toward a UE4-first direction with more tooling, documentation, and smoke coverage.

Why I made it

UE4.27 still matters in real production environments, but many newer tools and examples are written with UE5 assumptions. I wanted a workflow that stays realistic for teams and projects that still live on UE4.27.2.

What it does

  • Reads project, map, asset, and actor information from the open editor
  • Exposes editor and content workflows in an MCP-friendly shape
  • Supports practical operations across actors, assets, widgets, Blueprints, and inspection flows
  • Keeps the implementation grounded in what stock UE4.27 Python can reliably support

More detailed technical write-ups will be added here over time.
