2. Install dependencies:
   shell npm install
3. Build the project:
   shell npm run build
4. Configure your Shodan API key:
5. Create a .env file in the root directory
6. Add your Shodan API key: SHODAN_API_KEY=your_api_key_here
7. Or set it as an environment variable when running the server

MCP Configuration

To use this server with Claude or other MCP-compatible assistants, add it to your MCP configuration:

{
  "mcpServers": {
    "mcp-shodan-server": {
      "command": "node",
      "args": ["/path/to/shodan-mcp-server/build/index.js"],
      "env": {
        "SHODAN_API_KEY": "YOUR_SHODAN_API_KEY_HERE"
      }
    }
  }
}

Usage

Get Host Information

Use the get_host_info tool to retrieve detailed information about a specific IP address:

<use_mcp_tool>
<server_name>mcp-shodan-server</server_name>
<tool_name>get_host_info</tool_name>
<arguments>
{
  "ip": "8.8.8.8"
}
</arguments>
</use_mcp_tool>

With field selection and response sampling:

<use_mcp_tool>
<server_name>mcp-shodan-server</server_name>
<tool_name>get_host_info</tool_name>
<arguments>
{
  "ip": "8.8.8.8",
  "max_items": 3,
  "fields": ["ip_str", "ports", "hostnames", "location.country_name"]
}
</arguments>
</use_mcp_tool>

Search Shodan

Use the search_shodan tool to search Shodan's database for devices and services:

<use_mcp_tool>
<server_name>mcp-shodan-server</server_name>
<tool_name>search_shodan</tool_name>
<arguments>
{
  "query": "apache country:US",
  "page": 1,
  "facets": ["country", "org"]
}
</arguments>
</use_mcp_tool>

With result summarization:

<use_mcp_tool>
<server_name>mcp-shodan-server</server_name>
<tool_name>search_shodan</tool_name>
<arguments>
{
  "query": "apache country:US",
  "summarize": true
}
</arguments>
</use_mcp_tool>

Get Vulnerability Information

Use the get_vulnerabilities tool to retrieve information about a specific CVE:

<use_mcp_tool>
<server_name>mcp-shodan-server</server_name>
<tool_name>get_vulnerabilities</tool_name>
<arguments>
{
  "cve": "CVE-2021-44228"
}
</arguments>
</use_mcp_tool>

Scan Network Range

Use the scan_network_range tool to analyze devices within a CIDR range:

<use_mcp_tool>
<server_name>mcp-shodan-server</server_name>
<tool_name>scan_network_range</tool_name>
<arguments>
{
  "cidr": "192.168.1.0/24",
  "max_items": 10,
  "fields": ["ip_str", "ports", "hostnames", "os"]
}
</arguments>
</use_mcp_tool>

Get DNS Information

Use the get_dns_info tool to retrieve DNS records for a domain:

<use_mcp_tool>
<server_name>mcp-shodan-server</server_name>
<tool_name>get_dns_info</tool_name>
<arguments>
{
  "domain": "example.com"
}
</arguments>
</use_mcp_tool>

Get SSL Certificate Information

Use the get_ssl_info tool to analyze SSL certificates for a domain:

<use_mcp_tool>
<server_name>mcp-shodan-server</server_name>
<tool_name>get_ssl_info</tool_name>
<arguments>
{
  "domain": "example.com"
}
</arguments>
</use_mcp_tool>

Search for IoT Devices

Use the search_iot_devices tool to find specific types of IoT devices:

<use_mcp_tool>
<server_name>mcp-shodan-server</server_name>
<tool_name>search_iot_devices</tool_name>
<arguments>
{
  "device_type": "webcam",
  "country": "US",
  "max_items": 5
}
</arguments>
</use_mcp_tool>

Search Query Examples

• apache country:US: Find Apache servers in the United States
• port:22 country:DE: Find SSH servers in Germany
• webcam has_screenshot:true: Find webcams with screenshots
• org:"Microsoft" product:"Windows": Find Microsoft Windows devices
• ssl:Google: Find SSL certificates issued to Google

Advanced Usage

Pagination

For search results with many matches, you can paginate through the results by specifying the page parameter:

{
  "query": "apache country:US",
  "page": 2
}

Facets

Facets allow you to get summary information about the search results. For example, you can get a breakdown of the countries or organizations in the search results:

{
  "query": "apache",
  "facets": ["country", "org"]
}

Common facets include:

• country: Country code
• org: Organization
• domain: Domain name
• port: Port number
• asn: Autonomous System Number
• os: Operating System

Response Sampling

To reduce token usage, all responses are automatically sampled to include a limited number of items in arrays. You can control this with the max_items parameter:

{
  "query": "apache country:US",
  "max_items": 10
}

Field Selection

You can specify which fields to include in the results using the fields parameter:

{
  "query": "apache country:US",
  "fields": ["ip_str", "port", "org", "location.country_name"]
}

This supports nested fields using dot notation (e.g., location.country_name).

Result Summarization

For search results, you can request a summary instead of the full data:

{
  "query": "apache country:US",
  "summarize": true
}

This will return:

• Total result count
• Top 5 countries
• Top 5 organizations
• Top 5 ports

Future Enhancements

Future versions of this server will include:

• Advanced Vulnerability Correlation: Link CVEs with affected devices and potential exploits
• Historical Data Analysis: Track changes in device exposure over time
• Internet Maps & Real-time Data: Visualize internet-wide technology deployments
• Custom Filters: Create and save specialized filters for specific technologies
• Threat Intelligence Integration: Correlate Shodan data with threat feeds
• Reporting Capabilities: Generate comprehensive security reports
• API Rate Limit Management: Smart handling of API quotas and rate limits
• Geospatial Analysis: Advanced location-based analysis of internet devices
• Automated Scanning: Scheduled scans with alerting capabilities
