README

WSL-MCP

npm version License: MIT GitHub

一个支持持久化会话和终端轮询的 MCP (Model Context Protocol) 终端管理服务器。

特性

  • WSL 原生支持 - 专门针对 Windows + WSL 环境优化
  • Docker 后端支持 - 支持容器化隔离环境
  • 持久化会话 - 终端会话保持,环境变量和工作目录持久化
  • 终端轮询 - 支持长时间运行进程的输出轮询(核心创新功能)
  • 日志跟踪 - 类似 tail -f 的日志持续输出功能
  • 文件传输 - 支持文件上传/下载(Base64 编码)
  • 多后端支持 - 默认自动检测:WSL 优先 → Docker 备选,也可显式指定 backend

安装

使用 npx(推荐)

无需安装,直接使用 npx 运行:

npx wsl-mcp

在 MCP 客户端中配置

在 MCP 客户端(如 Claude Desktop、Kilo Code 等)配置中添加:

{
  "mcpServers": {
    "wsl-mcp": {
      "command": "npx",
      "args": ["-y", "wsl-mcp"],
      "env": {
        "WSL_MCP_WSL_DISTRIBUTION": "Ubuntu"
      }
    }
  }
}

注意: 使用 -y 标志可以自动确认 npx 的安装提示,适合自动化场景。
