Subdomain Intelligence

About

This Model Context Protocol (MCP) server empowers AI agents to perform comprehensive attack surface analysis. It efficiently enumerates a vast range of common subdomains, conducts deep DNS lookups (A, AAAA, CNAME, MX, TXT, NS records), and identifies potential subdomain takeover risks across numerous vulnerable services and hosting providers. Designed for cost-efficiency, it operates entirely without external APIs, leveraging Node.js's built-in DNS module for fast and parallel lookups, making it an ideal tool for security reconnaissance.

Key Features

• Enumerate over 120 common subdomains with associated IPs, CNAMEs, and record types.
• 0 GitHub stars
• Perform deep DNS lookups for specific subdomains (A, AAAA, CNAME, MX, TXT, NS records).
• Detect potential subdomain takeover vulnerabilities across 25+ services.
• Operates with zero external API costs and no rate limits, using built-in DNS resolution for speed.
• Conduct full attack surface analysis, including hosting providers and CNAMEs.

Use Cases

• Empowering AI agents with real-time, cost-free attack surface intelligence.
• Automated detection of subdomain takeover vulnerabilities for continuous security monitoring.
