SSH MCP Server: Secure Remote Access for AI Applications

Overview: What is SSH MCP Server?

The SSH MCP Server is an implementation designed to provide secure remote access and execution through the Model Context Protocol (MCP). This server is particularly valuable for integrating with AI applications such as Claude Desktop, Continue, Cursor, and many others. By leveraging the MCP protocol, it enables these applications to connect to specific data sources or tools seamlessly.

🔧 Core Features & MCP Capabilities

The SSH MCP Server offers a robust set of features that align with its core capabilities in supporting Model Context Protocol:

1. SSH Protocol Implementation: Utilizes the MCP protocol for secure remote access and execution, ensuring encrypted and reliable communication between clients and servers.
2. SQLite Database Integration: Stores SSH credentials securely using an SQLite database, providing persistent storage of essential connection details.
3. TypeScript Implementation: Built with TypeScript to enhance type safety and developer experience, making it easier to maintain and extend the server's functionality.

⚙️ MCP Architecture & Protocol Implementation

The architecture of the SSH MCP Server is designed to align closely with the Model Context Protocol framework:

• MCP Client Compatibility: Compatible with a range of popular AI applications including Claude Desktop, Continue, and Cursor. This ensures that developers can leverage this server for seamless integration across various tools.
• Data Flow Diagram: The following Mermaid diagram illustrates the MCP protocol flow:

By understanding this flow, developers can see how data moves from an AI application to the server and eventually reaches targeted tools.

🚀 Getting Started with Installation

Prerequisites

Before you begin, ensure that your environment meets these requirements:

• Node.js: Version 16 or higher is recommended.
• npm or yarn: For managing dependencies.
• TypeScript knowledge: Basic understanding for development purposes.

Quick Start Guide

1. Clone the Repository:

   git clone <repository-url>
   cd ssh-server
   

2. Install Dependencies:

   npm install
   

3. Build the Project:

   npm run build
   

4. Start the Server:

   npm start
   

The server will now be running on the default port specified in your source code.

💡 Key Use Cases in AI Workflows

Use Case 1: Running Remote Commands with SSH

Developers can use tools like ssh_exec to run commands remotely. This is particularly useful for managing and deploying applications across multiple machines:

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

Use Case 2: Managing SSH Credentials

The ability to add, list, and remove SSH credentials ensures that sensitive information is managed securely:

• Add a New Credential:

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

• List All Credentials:

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

• Remove a Credential:

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

🔌 Integration with MCP Clients

MCP Client Compatibility Matrix

MCP Client	Resources	Tools	Prompts	Status
Claude Desktop	✅	✅	✅	Full Support
Continue	✅	✅	✅	Full Support
Cursor	❌	✅	❌	Tools Only

Note: The table indicates support levels for each category. A "✅" signifies full support, while a "❌" indicates limited or no support.

📊 Performance & Compatibility Matrix

To ensure optimal performance and compatibility, developers should refer to the server's implementation details:

• Performance: Benchmarks show the server can handle several SSH connections simultaneously without significant degradation.
• Compatibility: The server is tested against known MCP Clients to ensure seamless integration.

🛠️ Advanced Configuration & Security

Beyond basic setup, developers have the ability to customize their environment further:

• Configuration Files: Use configuration files like mcpServers to set up multiple MCP servers and define custom behaviors.

  Example:

  {
    "mcpServers": {
      "[server-name]": {
        "command": "npx",
        "args": ["-y", "@modelcontextprotocol/server-[name]"],
        "env": {
          "API_KEY": "your-api-key"
        }
      }
    }
  }
