RooCode 使用方法:

  1. 使用 vscode 打开该工具,此时目录结构如下:
.
├── README.md
├── jeb-mcp
│   ├── pyproject.toml
│   ├── src
│   │   └── jeb_mcp
│   │       ├── MCP.py
│   │       ├── server.py
│   │       └── server_generated.py
│   └── uv.lock
└── sample_cline_mcp_settings.json
  1. 点击左侧活动栏 rooCode 图标,然后继续点击 RooCode 对话框右上角 ...,最后点击编辑项目 MCP 按钮,

会在当前目录下产生一个 .roo 目录,其中包含 mcp.json 文件。

  1. 修改 mcp.json 文件为下列内容:
