ssh-mcp

AI-powered remote server management via the Model Context Protocol. Persistent SSH sessions, full SFTP operations, system monitoring, and log tools.

Overview

ssh-mcp is an MCP (Model Context Protocol) server that turns any AI coding agent into a full-featured remote server administration tool. It maintains persistent SSH connections, executes commands, transfers files, monitors system health, and searches logs — all through natural language conversations.

Features

| Category | Tools | Description | |----------|-------|-------------| | Session | ssh_connect, ssh_disconnect, ssh_sessions | Persistent connection pool with 30-min idle auto-cleanup | | Execution | ssh_exec, ssh_script, ssh_exec_bg, ssh_exec_stop, ssh_exec_bg_result | Run commands with smart timeout (auto-converts to background on timeout). Supports cwd, env, sudo | | SFTP | ssh_file_read, ssh_file_write, ssh_file_list, ssh_file_delete, ssh_file_rename, ssh_file_mkdir, ssh_file_chmod, ssh_file_stat | Full file operations with recursive delete/chmod, mkdir -p support | | Monitoring | ssh_sysinfo, ssh_processes, ssh_disk_usage | OS info, process list (sorted by CPU/memory), disk usage | | Logs | ssh_log_tail, ssh_log_search | View log tails, grep with context |

Quick Start

Prerequisites

Node.js >= 18
npm

Install

git clone https://github.com/civilization-os/ssh-mcp.git
cd ssh-mcp
npm install
npm run build

Usage Examples

Session mode (recommended — reuse connection):

ssh_connect  host="192.168.1.1"  username="root"  password="xxx"
→ Session created: sess_xxx

ssh_exec     sessionId="sess_xxx"  command="top -b -n 1 | head -5"
ssh_file_write sessionId="sess_xxx"  path="/tmp/test.txt"  content="hello world"
ssh_sysinfo  sessionId="sess_xxx"
ssh_disconnect sessionId="sess_xxx"

Stateless mode (credentials per call):

ssh_exec  host="192.168.1.1"  username="root"  password="xxx"  command="whoami"

Smart Timeout

All ssh_exec commands automatically wrap with nohup. If a command exceeds the timeout (default 10 min), it converts to a background task and returns a runId so you can:

Check output: ssh_exec_bg_result sessionId="..." runId="bg_xxx"
Stop it: ssh_exec_stop sessionId="..." runId="bg_xxx"

MCP Configuration by Client

Claude Desktop / Claude Code

.mcp.json:

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

Or via CLI:

claude mcp add ssh -- node /path/to/ssh-mcp/build/index.js

Cursor

In Cursor settings → Features → MCP Servers → Add:

{
  "name": "ssh",
  "type": "command",
  "command": "node",
  "args": ["/path/to/ssh-mcp/build/index.js"]
}

Windsurf

In .windsurf/config.json or global MCP config:

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

Continue (VS Code / JetBrains)

~/.continue/config.json:

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

OpenCode

In OpenCode config:

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

Note: All clients above follow the same MCP stdio protocol. The only difference is where the config file lives. Replace /path/to/ssh-mcp/ with your actual install directory.

Architecture

Dual-mode design:

Session mode: ssh_connect first → returns sessionId → reuse across calls
Stateless mode: Pass host/username/password with every call
