MCP Servers

cloud-to-local

Enables cloud agents to securely operate local machine resources (files, commands, screenshots) via standard MCP protocol.

Cloud2Local

让云端智能体安全地操作你的本机。

云端 Agent 本来够不着你的电脑。Cloud2Local 在本机开一个 MCP Server，把文件读写、目录浏览、白名单命令、截屏等能力暴露成标准 MCP 接口；云端填 URL + Token 即可接入。

项目特色

特色	说明
标准 MCP 协议	支持 Streamable HTTP（`/mcp`）与兼容旧客户端的 SSE（`/sse`）
云端即连	启动后直接给出云端接入地址，可一键复制客户端配置
按需公网暴露	默认仅本机访问，需要时再手动开启自动暴露
鉴权与边界	Token 鉴权、`fileRoot` 路径沙箱、命令白名单、脚本超时
本机工具箱	`read_file` / `write_file` / `list_directory` / `run_command` / `screenshot`
桌面可视化	状态、配置、运行日志、启停都在 GUI 里完成
跨平台	Windows / macOS / Linux（Electron）

本机已经在跑的 Agent 不必再绕一层 MCP 调本机；这套主要给 云端 / 远程智能体 用。
连上后工具列表由协议 list_tools 自动发现，不需要客户端手写工具目录。

30 秒上手

两个端口别混： 本机 MCP 默认 8000；云端访问默认公网口 18000。云端不要填 8000。

启动应用，首页先连上外网通道
打开 MCP Server 页
设置 Token、收窄 文件根目录、确认允许命令
本机端口 8000，公网端口 18000，先设 Token；需要公网时再开「自动公网暴露」 → 保存 → 启动
确认「运行中」，云端地址端口是 18000
云端客户端填：

{
  "mcpServers": {
    "cloud-to-local": {
      "url": "http://PUBLIC_HOST:18000/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_TOKEN"
      }
    }
  }
}

服务器至少放行：控制口 7000 + 公网业务口 18000。

更细的接入步骤见 docs/云端MCP接入教程.md。

安全（必读）

这是把本机能力放到网上，请当生产接口对待：

Token 必开，不要空着给公网
fileRoot 收窄到工作目录，不要整盘
allowedCommands 只留必要命令
不用时 停止 Server（若开了自动暴露会一并关掉）
有条件上 HTTPS / 反代；裸 HTTP 会明文传 Token

开发

npm install
# Windows / 部分环境需清除 ELECTRON_RUN_AS_NODE
env -u ELECTRON_RUN_AS_NODE npm run dev

npm run build
npm run build:electron

技术栈：Electron + Vue3 + Vite + Element Plus + MCP SDK。
