SSH MCP Server

A Model Context Protocol (MCP) server implementation that provides SSH capabilities. This server allows for secure remote access and execution through the MCP protocol.

Features

• SSH server implementation using MCP protocol
• SQLite database integration for data persistence
• TypeScript implementation for type safety and better development experience

Prerequisites

• Node.js (v16 or higher recommended)
• npm or yarn package manager
• TypeScript knowledge for development

Installation

1. Clone the repository:

git clone <repository-url>
cd ssh-server

2. Install dependencies:

npm install

3. Build the project:

npm run build

Usage

Configuration

The server uses a SQLite database (ssh.db) to store SSH credentials. The database file will be created automatically when the server starts.

Tools

The server provides the following tools:

ssh_exec

Execute a command over SSH.

Input Parameters:

• host: The host to connect to. (required)
• command: The command to execute. (required)
• username: The username to use for the SSH connection. (required)
• privateKeyPath: The path to the private key file. (required)

Example Usage:

{
    "tool_name": "ssh_exec",
    "arguments": {
        "host": "example.com",
        "command": "ls -l",
        "username": "user",
        "privateKeyPath": "/path/to/private/key"
    }
}

Note: The privateKeyPath must be a valid path to a private key file.

add_credential

Add a new SSH credential.

Input Parameters:

• name: The name of the credential. (required)
• host: The host to connect to. (required)
• username: The username to use for the SSH connection. (required)
• privateKeyPath: The path to the private key file. (required)

Example Usage:

{
    "tool_name": "add_credential",
    "arguments": {
        "name": "my_credential",
        "host": "example.com",
        "username": "user",
        "privateKeyPath": "/path/to/private/key"
    }
}

Note: The privateKeyPath must be a valid path to a private key file.

list_credentials

List all stored SSH credentials.

Input Parameters:

• None

Example Usage:

{
    "tool_name": "list_credentials",
    "arguments": {}
}

remove_credential

Remove a stored SSH credential.

Input Parameters:

• name: The name of the credential to remove. (required)

Example Usage:

{
    "tool_name": "remove_credential",
    "arguments": {
        "name": "my_credential"
    }
}

Starting the server

npm start

The server will start running on the configured port (default settings can be modified in the source code).
