CVE Lookup Tool - Name: `cve_lookup` - Description: Query detailed vulnerability information from Shodan's CVEDB - Parameters: * `cve` (required): CVE identifier in format CVE-YYYY-NNNNN (e.g., CVE-2021-44228) - Returns: * Basic Information (ID, published date, summary) * Severity Scores: - CVSS v2 and v3 with severity levels - EPSS probability and ranking * Impact Assessment: - KEV status - Proposed mitigations - Ransomware associations * Affected products (CPEs) * References ### 4. DNS Lookup Tool - Name: `dns_lookup` - Description: Resolve domain names to IP addresses using Shodan's DNS service - Parameters: * `hostnames` (required): Array of hostnames to resolve - Returns: * DNS resolutions mapping hostnames to IPs * Summary of total lookups and queried hostnames ### 5. Reverse DNS Lookup Tool - Name: `reverse_dns_lookup` - Description: Perform reverse DNS lookups to find hostnames associated with IP addresses - Parameters: * `ips` (required): Array of IP addresses to lookup - Returns: * Reverse DNS resolutions mapping IPs to hostnames * Summary of total lookups and results ### 6.

Verify your API key: - Must be a valid Shodan API key from your [account settings](https://account.shodan.io/) - Ensure the key has sufficient credits/permissions for the operation - Check for extra spaces or quotes around the key in the configuration - Verify the key is correctly set in the SHODAN_API_KEY environment variable 2. Common Error Codes: - 401 Unauthorized: Invalid API key or missing authentication - 402 Payment Required: Out of query credits - 429 Too Many Requests: Rate limit exceeded 3. Configuration Steps: a. Get your API key from [Shodan Account](https://account.shodan.io/) b. Add it to your configuration file: ```json { "mcpServers": { "shodan": { "command": "mcp-shodan", "env": { "SHODAN_API_KEY": "your-actual-api-key-here" } } } } ``` c. Save the config file d. Restart Claude Desktop 4. Testing Your Key: - Try a simple query first (e.g., dns_lookup for "google.com") - Check your [Shodan account dashboard](https://account.shodan.io/) for credit status - Verify the key works directly with curl: ```bash curl "https://api.shodan.io/dns/resolve?hostnames=google.com&key=your-api-key" ``` ### Module Loading Issues If you see module loading errors: 1. For global installation: Use the simple configuration shown in Quick Start 2. For source installation: Ensure you're using Node.js v18 or later ## Development To run in development mode with hot reloading: ```bash npm run dev ``` ## Error Handling The server includes comprehensive error handling for: - Invalid API keys - Rate limiting - Network errors - Invalid input parameters - Invalid CVE formats - Invalid CPE lookup parameters - Invalid date formats - Mutually exclusive parameter validation ## Version History - v1.0.12: Added reverse DNS lookup and improved output formatting - v1.0.7: Added CVEs by Product search functionality and renamed vulnerabilities tool to cve_lookup - v1.0.6: Added CVEDB integration for enhanced CVE lookups and CPE search functionality - v1.0.0: Initial release with core functionality ## Contributing 1.
