MCP Integration

This server can be integrated with Claude or other MCP-compatible AI assistants. To add it to Claude Desktop or Claude.app:

1. Add the server to your MCP settings:

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

2. Restart Claude to load the new MCP server.

API Limitations

Some Shodan API endpoints require a paid membership. The following features are only available with a paid Shodan API key:

• Search functionality (search_shodan, scan_network_range, get_ssl_info, search_iot_devices, get_host_count, get_domain_info)

• Network scanning

• SSL certificate lookup

• IoT device search

Note: CVE database functionality (get_cve_info, search_cves, get_cpes, get_newest_cves, get_kev_cves, get_cves_by_epss) is completely free and does not require a paid Shodan subscription.
