SSH Tools MCP server

This MCP (Model Context Protocol) based SSH tool allows you to connect to remote servers and execute commands using a simple API. It provides a straightforward way to establish SSH connections, run commands like nvidia-smi, and properly disconnect from servers.

Installation

To install and run the SSH Tools MCP server:

1. Install the required dependencies:

   pip install -r requirements.txt
   

2. Start the MCP server:

   python ssh_server.py
   

Available Tools

The MCP server provides three main tools for SSH operations:

connect_ssh

Establishes a connection to an SSH server.

Parameters:

• hostname: Server IP address or hostname
• password: SSH password
• username: SSH username (defaults to "root")
• port: SSH port (defaults to 22)

run_command

Executes a command on the connected SSH server.

Parameters:

• command: The command to execute (e.g., "nvidia-smi")

disconnect_ssh

Terminates the current SSH connection.

Usage Examples

Connecting to a Server

To establish an SSH connection:

connect_ssh(hostname="192.168.1.100", password="your_password")

You can also specify a custom username and port:

connect_ssh(
    hostname="192.168.1.100", 
    username="admin", 
    password="your_password", 
    port=2222
)

Running Commands

After establishing a connection, you can execute commands:

run_command(command="nvidia-smi")

run_command(command="ls -la /home")

Disconnecting

Always disconnect when finished:

disconnect_ssh()

Important Notes

• Ensure the target server has password authentication enabled
• Always call disconnect_ssh() when you're done to properly close connections
• All commands return either the command output or error messages
• Only one SSH connection can be active at a time per server instance

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "ssh-tools" '{"command":"python","args":["ssh_server.py"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "ssh-tools": {
            "command": "python",
            "args": [
                "ssh_server.py"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "ssh-tools": {
            "command": "python",
            "args": [
                "ssh_server.py"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
