Shodan MCP Server

A Model Context Protocol (MCP) server that provides access to Shodan’s internet scanning capabilities through a standardized interface.

Overview

This server implements the Model Context Protocol to expose Shodan’s powerful internet scanning and reconnaissance capabilities. It provides a standardized interface for querying Shodan’s database of internet-connected devices, services, and vulnerabilities.

Features

• Search Capabilities: Query Shodan’s database using advanced search filters
• DNS Lookup: Resolve domain names and get detailed DNS information
• CVE Information: Get detailed information about Common Vulnerabilities and Exposures
• Get Vulnerabilities: Get detailed infor Vulnerabilities related to an IP address
• Standardized Interface: Uses MCP protocol for consistent communication
• Environment Variable Support: Secure API key management through environment variables

Prerequisites

• Node.js (v14 or higher)
• npm (v6 or higher)
• Shodan API key

Installation

1. Clone the repository:

   git clone https://github.com/X3r0K/Shodan-MCP-Server-Inspector.git
   cd shodan-mcp-server-Inspector
   

2. Install dependencies:

   npm install
   

3. Create a .env.local file in the root directory and add your Shodan API key:

   SHODAN_API_KEY=your_api_key_here
   

Usage

Starting the Server

1. Build the server:

   npm run build
   

2. Start the server:

   node build/index.js
   

Available Tools

1. Search Tool

   • Query: Search for devices and services using Shodan’s search syntax
   • Example: log4j country:US city:Atlanta
   • Returns: List of matching devices with detailed information

2. DNS Lookup Tool

   • Query: Domain name to resolve
   • Example: example.com
   • Returns: DNS records and related information

3. CVE Info Tool

   • Query: CVE identifier
   • Example: CVE-2021-44228
   • Returns: Detailed vulnerability information

Example Queries

// Search for Log4j vulnerable systems in the US
{
  "query": "log4j country:US"
}

// DNS lookup for a domain
{
  "query": "example.com"
}

// Get CVE information
{
  "query": "CVE-2021-44228"
}

Using the MCP Inspector

You can use the MCP inspector to interact with the server directly:

1. Install the MCP inspector:

npm install -g @modelcontextprotocol/inspector

2. Run the inspector with your server:

npx @modelcontextprotocol/inspector build/index.js

The inspector provides an interactive interface to:

• Test all available tools
• View tool documentation
• Debug server responses
• Monitor server status

Environment Variables

• SHODAN_API_KEY: Your Shodan API key (required)
• PORT: Server port (optional, defaults to 3000)
• LOG_LEVEL: Logging level (optional, defaults to ‘info’)

Error Handling

The server implements comprehensive error handling for:

• Invalid API keys
• Rate limiting
• Network issues
• Invalid queries
• Server errors

Security Considerations

1. API Key Protection:

   • Never commit API keys to version control
   • Use environment variables for sensitive data
   • Rotate API keys regularly

2. Rate Limiting:

   • Respect Shodan’s API rate limits
   • Implement client-side rate limiting

3. Data Privacy:

   • Filter sensitive information from responses
   • Implement access controls as needed
