ssh-mcp
ssh-mcp v4.0
用于在 Linux 主机和网络设备上执行持久化 SSH 操作的 MCP 服务器。
功能特性
持久化 SSH 连接,支持自动重连
安全凭据存储,通过 Windows 凭据管理器实现
网络设备支持:Cisco IOS/IOS-XE/XR、MikroTik、FortiGate、Juniper
配置管理:网络设备的备份、恢复、差异对比
SFTP:上传、下载、列出远程文件
SSH 隧道:持久化端口转发
速率限制:防止设备过载(命令之间最小间隔 100ms)
智能连接:使用
ssh_connect(alias='vps')自动加载已保存的凭据

快速开始
1. 保存服务器(仅需一次)
ssh_save_server(
alias='vps',
host='192.168.10.1',
username='sassogba',
password='your-password',
auto_connect=True # Auto-connect on startup
)2. 连接(简单模式)
ssh_connect(alias='vps') # Loads credentials from servers.json3. 执行命令
ssh_exec(alias='vps', command='df -h')
ssh_exec_sudo(alias='vps', command='systemctl restart nginx', sudo_password='...')v4.0 新增内容
智能连接模式
ssh_connect现在只需提供别名即可自动加载凭据无需每次都提供主机、用户名、密码
修复了 Claude Code 集成问题
关键修复
超时处理:现在会抛出
TimeoutError,而不是静默返回不完整的缓冲区速率限制:网络命令之间最小间隔 100ms,防止设备过载
消除魔法数字:为 shell 尺寸使用命名常量
文档
新增
CLAUDE_CODE_USAGE.md,包含完整的使用示例新增
CLAUDE_CODE_SETUP.md,用于配置说明新增
CHANGELOG.md,包含完整的版本历史
安全模型
servers.json 仅保存非敏感元数据。密钥存储在 Windows 凭据管理器中,目标名称格式如下:
ssh-mcp:<alias>:passwordssh-mcp:<alias>:key_passphrase
主机密钥策略
strict:默认值,拒绝未知主机密钥(生产环境)auto_add:接受未知主机密钥(仅限实验室环境)
网络设备
支持的设备类型:
cisco- Cisco IOS/IOS-XEcisco_xr- Cisco IOS-XRmikrotik- MikroTik RouterOSfortigate- FortiGate FortiOSjuniper- Juniper JunOSgeneric- Linux/Unix(默认)
示例:Cisco 备份
# Save once
ssh_save_server(
alias='cisco-core',
host='10.0.0.1',
username='admin',
password='...',
device_type='cisco',
auto_connect=True
)
# Connect
ssh_connect(alias='cisco-core')
# Backup config

)与 Claude Code 配合使用
简要说明:
1. Save: ssh_save_server(alias='vps', host='192.168.10.1', username='sassogba', password='...')
2. Connect: ssh_connect(alias='vps')
3. Execute: ssh_exec(alias='vps', command='df -h')提供 18 个工具
连接管理
ssh_connect- 建立持久化 SSH 连接(智能模式:只需提供别名)ssh_disconnect- 关闭连接和隧道ssh_list- 列出活动连接及其状态
持久化配置
ssh_save_server- 将服务器保存到 servers.json(密钥存储在凭据管理器中)ssh_remove_server- 移除已保存的服务器ssh_list_servers- 列出所有已保存的服务器
Linux/Unix 执行
ssh_exec- 执行 shell 命令ssh_exec_sudo- 使用 sudo 执行(自动注入密码)
网络设备执行
ssh_exec_network- 在网络设备上执行命令(处理分页、提示符)ssh_push_config- 部署配置块ssh_backup_config- 将运行配置备份到本地文件ssh_restore_config- 从备份文件恢复配置ssh_diff_config- 对比配置(git 风格差异)
SFTP
ssh_upload- 上传文件到远程服务器ssh_download- 从远程服务器下载文件ssh_list_remote- 列出远程目录内容
隧道
ssh_tunnel- 创建持久化 SSH 隧道(端口转发)ssh_close_tunnel- 按标签关闭隧道
架构
SSHPool:线程安全的连接池,支持自动重连
SSHConnection:每连接状态,使用 RLock 保证线程安全
ThreadPoolExecutor:为 Paramiko(同步库)提供 async/await 封装
