unreal-mcp-ue4-for-OHD
UE4.25.4-first MCP server for Operation Harsh Doorstop modding via Unreal Python Remote Execution (stdio transport)
Fork of runreal/unreal-mcp, heavily refactored UE4-first (via a UE4.27.2 stage) and retargeted here to UE4.25.4 for the OHDCore Mod Kit: same transport and tool surface, with version pins, docs links, and Python-dialect constraints adjusted for the kit's embedded Python 2.7.14. Port, tool, docs, and smoke-test work were developed with assistance from OpenAI Codex.
[!NOTE]
Still under active development — expect bugs, rough edges, and UE4.25-specific limitations.
Published package: unreal-mcp-ue4-for-ohd · Registry name: io.github.RibatTRW/unreal-mcp-ue4-for-ohd
[!CAUTION]
Not an official Epic Games project. Any connected MCP client can inspect and modify your open editor session — use a disposable test project first, especially for asset or world-generation tools.

Requirements
Reference: Unreal Engine Python API 4.25. No custom C++ plugin is required — the server uses the editor's built-in Python Remote Execution. UE5-only scripting features are not reintroduced; unreliable graph/binding flows are excluded from the MCP surface or return a clear message instead of failing silently.
