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
