rog0x/mcp-network-tools

Exposes DNS lookups, IP geolocation, SSL certificate inspection, WHOIS queries, and HTTP latency testing to Claude through Node.js built-in modules. You get A/AAAA/MX/TXT records, reverse DNS, and propagation checks across public resolvers. IP info pulls from ip-api.com for geolocation and ASN data. SSL checks give you certificate chains, expiry dates, and cipher details. HTTP ping runs multiple requests and returns p95 latency alongside min/max/avg stats. Useful when you're debugging connectivity, verifying DNS propagation after a change, checking certificate validity before expiry, or measuring endpoint performance without leaving your Claude conversation.
