Unreal MCP Ue4

unreal-mcp-ue4 started from the core idea and early workflow shape of runreal/unreal-mcp, but it has since been heavily refactored for Unreal Engine 4.27.2 and expanded with many new tools, UE4-specific compatibility layers, documentation, and smoke coverage. At this point, the original inspiration remains, but the public surface and day-to-day behavior are substantially different and UE4-first.

People who work with codex, ue4 and unreal editor and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Unreal MCP Ue4

Claude Code

claude mcp add conaman-unreal-mcp-ue4 -- npx -y unreal-mcp-ue4

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "conaman-unreal-mcp-ue4": {

      "args": [
        "-y",

}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

03 · What Unreal MCP Ue4 can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

Limitations (from the README)

- World-building and structure-generation tools use UE4.27-friendly preset builders based on engine basic-shape assets. - Common UMG widget-tree editing works with native PanelWidget parents, but delegate binding helpers remain unavailable in stock UE4.27 Python. - UMG absolute positioning targets CanvasPanel slots in UE4.27. Use manage_widget.ensure_canvas_root when a Widget Blueprint has a non-Canvas root but needs
