What is the DNS And WHOIS Query MCP Server?

Perform DNS lookups, WHOIS queries, connectivity testing, TLS certificate analysis, HTTP endpoint monitoring, and hostname resolution, all from your trusty AI.

What you get

mcp-netutils is a Model Context Protocol (MCP) server providing comprehensive network and domain analysis capabilities for AI assistants. It enables AI models to perform DNS lookups, WHOIS queries, connectivity testing, TLS certificate analysis, HTTP endpoint monitoring, and hostname resolution.

  • Local DNS Queries — Perform DNS lookups using the OS-configured DNS servers
  • Remote DNS-over-HTTPS — Perform secure DNS queries via Cloudflare and Google DNS-over-HTTPS services
  • WHOIS Lookups — Perform WHOIS queries to get domain registration information
  • Hostname Resolution — Convert hostnames to their corresponding IP addresses (IPv4, IPv6, or both)
  • Ping Operations — Test connectivity and measure response times to hosts using ICMP
  • HTTP Ping Operations — Test HTTP endpoints and measure detailed response times including DNS, connection, TLS, and TTFB timing
