Quick Start

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

Features

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

Tools

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)

Installation

Clone the repository:

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

Install dependencies:
```
npm install
```

Client Setup

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.

Claude Code

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?"

For more information about MCP in Claude Code, see the official documentation.

Testing

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

npm run inspect
