README

UE-Editor-MCPServer

将UE Editor封装为MCP Server供Agent使用以实现Agent自动化迭代 python新手，欢迎大佬们提各种建议

  • 当前版本基于5.5开发 暂时不保证其他版本引擎下的可用性（按道理只要Pyhton版本及PythonScriptPlugin跟5.5一致即可），后续会考虑支持UE5和部分UE4版本
  • 目前仅保证Win下稳定

Setup

clone当前项目至项目或者引擎的plugin并编译，引擎启动后会自动启动MCPServer

  • 需自行保证pip源连接畅通
  • 需要C++版本的项目，未来会上架商店

How To Use

目前仅提供了示例版本的MCPServer，若想添加功能在.Content/Python/MCPServer.py中修改即可
