SSH MCP Server is a local Model Context Protocol (MCP) server that exposes SSH control for Linux and Windows systems, enabling LLMs and other MCP clients to execute shell commands securely via SSH.

• Quick Start
• Features
• Installation
• Client Setup
• Testing
• Disclaimer
• Support

• Install SSH MCP Server
• Configure SSH MCP Server
• Set up your MCP Client (e.g. Claude Desktop, Cursor, etc)
• Execute remote shell commands on your Linux or Windows server via natural language

• MCP-compliant server exposing SSH capabilities
• Execute shell commands on remote Linux and Windows systems
• Secure authentication via password or SSH key
• Built with TypeScript and the official MCP SDK
• Configurable timeout protection with automatic process abortion
• Graceful timeout handling - attempts to kill hanging processes before closing connections

• exec: Execute a shell command on the remote server
  • Parameters:
    • command (required): Shell command to execute on the remote SSH server
  • Timeout Configuration:
    • Timeout is configured via command line argument --timeout (in milliseconds)
    • Default timeout: 60000ms (1 minute)
    • When a command times out, the server automatically attempts to abort the running process before closing the connection
  • Max Command Length Configuration:
    • Max command characters are configured via --maxChars
    • Default: 1000
    • No-limit mode: set --maxChars=none or any <= 0 value (e.g. --maxChars=0)

1. Clone the repository:

   git clone https://github.com/tufantunc/ssh-mcp.git
   cd ssh-mcp

2. Install dependencies:

   npm install

You can configure your IDE or LLM like Cursor, Windsurf, Claude Desktop to use this MCP Server.

Required Parameters:

• host: Hostname or IP of the Linux or Windows server
• user: SSH username

Optional Parameters:

• port: SSH port (default: 22)
• password: SSH password (or use key for key-based auth)
• key: Path to private SSH key
• timeout: Command execution timeout in milliseconds (default: 60000ms = 1 minute)
• maxChars: Maximum allowed characters for the command input (default: 1000). Use none or 0 to disable the limit.

You can add this MCP server to Claude Code using the claude mcp add command. This is the recommended method for Claude Code.

Basic Installation:

claude mcp add --transport stdio ssh-mcp -- npx -y ssh-mcp -- --host=YOUR_HOST --user=YOUR_USER --password=YOUR_PASSWORD

Installation Examples:

With Password Authentication:

claude mcp add --transport stdio ssh-mcp -- npx -y ssh-mcp -- --host=192.168.1.100 --port=22 --user=admin --password=your_password

With SSH Key Authentication:

claude mcp add --transport stdio ssh-mcp -- npx -y ssh-mcp -- --host=example.com --user=root --key=/path/to/private/key

With Custom Timeout and No Character Limit:

claude mcp add --transport stdio ssh-mcp -- npx -y ssh-mcp -- --host=192.168.1.100 --user=admin --password=your_password --timeout=120000 --maxChars=none

Installation Scopes:

You can specify the scope when adding the server:

• Local scope (default): For personal use in the current project

  claude mcp add --transport stdio ssh-mcp --scope local -- npx -y ssh-mcp -- --host=YOUR_HOST --user=YOUR_USER --password=YOUR_PASSWORD

• Project scope: Share with your team via .mcp.json file

  claude mcp add --transport stdio ssh-mcp --scope project -- npx -y ssh-mcp -- --host=YOUR_HOST --user=YOUR_USER --password=YOUR_PASSWORD

• User scope: Available across all your projects

  claude mcp add --transport stdio ssh-mcp --scope user -- npx -y ssh-mcp -- --host=YOUR_HOST --user=YOUR_USER --password=YOUR_PASSWORD

Verify Installation:

After adding the server, restart Claude Code and ask Cascade to execute a command:

"Can you run 'ls -la' on the remote server?"

You can use the MCP Inspector for visual debugging of this MCP Server.

npm run inspect
