SSH MCP Server

基于 Model Context Protocol (MCP) 的 SSH 服务器工具集,支持在远程服务器上执行命令和传输文件。

两种使用方式

本工具支持两种连接 SSH 服务器的方式

方式一:直接参数(临时连接)

直接在工具调用中指定服务器信息,适合临时操作:

{
  "tool": "ssh_execute_command",
  "arguments": {
    "host": "192.168.1.100",
    "port": 22,
    "username": "root",
    "password": "your_password",
    "command": "docker ps"
  }
}

方式二:配置文件(推荐)

预先配置服务器信息,通过名称调用,适合频繁使用的服务器:

  1. 创建 ssh-mcp.config.json 配置文件
  2. 使用 server 参数指定服务器名称
{
  "tool": "ssh_execute_command",
  "arguments": {
    "server": "production",
    "command": "docker ps"
  }
}

优势:

  • 无需每次输入密码
  • 支持多服务器配置
  • 通过 ssh_list_servers 工具查询可用服务器
  • Agent 可自主发现并使用服务器

安装

npm install
npm run build

MCP 客户端配置

OpenCode

配置文件位置:C:\Users\<用户名>\.config\opencode\opencode.jsonc

{
  "mcp": {
    "ssh-mcp": {
      "type": "local",
      "command": ["node", "path/to/ssh-mcp/dist/index.js"],
      "enabled": true
    }
  }
}

Claude Code

配置文件位置:C:\Users\<用户名>\.claude\CLAUDE.json

{
  "mcpServers": {
    "ssh-mcp": {
      "command": "node",
      "args": ["/path/to/ssh-mcp/dist/index.js"],
      "disabled": false
    }
  }
}

Claude Desktop

配置文件位置:

  • Windows: %APPDATA%/Claude/claude_desktop_config.json
  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Linux: ~/.config/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "ssh-mcp": {
      "command": "node",
      "args": ["/path/to/ssh-mcp/dist/index.js"],
      "disabled": false
    }
  }
}

SSH 配置文件

创建配置文件

{
  "servers": {
    "production": {
      "host": "192.168.1.100",
      "port": 22,
      "username": "root",
      "password": "your_password",
      "timeout": 60000
    },
    "development": {
      "host": "192.168.1.50",
      "port": 2222,
      "username": "admin",
      "password": "dev_password"
    }
  },
  "defaultServer": "development"
}

配置文件位置(按优先级)

  1. SSH_MCP_CONFIG 环境变量指定路径
  2. 当前项目目录 ssh-mcp.config.json
  3. 当前项目目录 .ssh-mcp-config.json
  4. 用户主目录 .ssh-mcp-config.json

配置文件参数说明

参数 必填 默认值 说明
host - SSH 服务器地址
port 22 SSH 端口
username - 用户名
password - 密码
timeout 30000 超时时间(毫秒)
