## Tools
- dns_lookup - Look up all common DNS records (A, AAAA, NS, MX, TXT, CNAME, SOA) for a domain. Returns results from a specified DNS server. Endpoint: https://mcp.nslookup.io/mcp
- dns_record - Look up a specific DNS record type for a domain. Supports 53 record types including A, AAAA, MX, TXT, CNAME, SOA, PTR, CAA, SRV, DNSKEY, DS, TLSA, HTTPS, SPF, and more. Endpoint: https://mcp.nslookup.io/mcp
- dns_propagation - Check DNS propagation for a domain across 18+ global DNS servers (Cloudflare, Google, Quad9, OpenDNS, regional servers, and authoritative nameservers). Shows if DNS changes have propagated worldwide. Endpoint: https://mcp.nslookup.io/mcp
- webservers - Get the IP addresses (both IPv4 and IPv6) for a domain by looking up A and AAAA records. Also returns the punycode and unicode domain representations. Endpoint: https://mcp.nslookup.io/mcp
- ssl_certificate - Check the SSL/TLS certificate for a domain. Returns issuer, expiry date, days until expiry, certificate chain validity, cipher strength, SAN domains, fingerprint, and TLS protocol version. Endpoint: https://mcp.nslookup.io/mcp
- bimi_vmc - Check BIMI (Brand Indicators for Message Identification) and VMC (Verified Mark Certificate) for a domain. Returns BIMI DNS record status, VMC certificate details, logo URL, trademark info, and expiry. Endpoint: https://mcp.nslookup.io/mcp
- security_scan - Run a security scan on a domain to detect DNS misconfigurations, missing SPF/DKIM/DMARC records, cookie security issues, and other web security vulnerabilities. Returns findings with severity levels (critical, high, medium, low, info). Endpoint: https://mcp.nslookup.io/mcp
- uptime_check - Perform a one-time HTTP uptime check on a URL from a single location. Returns whether the site is up or down, HTTP status code, and response time in milliseconds. For multi-location checks, use uptime_check_multi instead. Endpoint: https://mcp.nslookup.io/mcp
- uptime_check_multi - Check if a website is up or down from 7 global locations simultaneously: Amsterdam, Sydney, London, Frankfurt, Delhi, Warsaw, and South Carolina. Returns status, response time, and HTTP status code for each location. Endpoint: https://mcp.nslookup.io/mcp
- dns_health - Run a comprehensive DNS health audit on a domain — 39 checks across 7 categories: DNSSEC (chain of trust, algorithms, validation), MX & email (PTR, MTA-STS, redundancy), DNS hygiene (SPF conflicts, wildcards, apex CNAME), TTL & SOA configuration, nameserver setup (diversity, lame delegation, EDNS0), CAA certificates, and operational maturity (security.txt, abuse mailbox). Returns an overall severity-weighted score (0–100) plus per-category scores. Endpoint: https://mcp.nslookup.io/mcp
- geo_checker - Check a domain's GEO (Generative Engine Optimization) score — how well the site is optimized for AI search engines like ChatGPT, Gemini, Claude, and Perplexity. Returns three scores (Technical Readiness, Entity Readiness, Answer Readiness), AI crawler access status, structured data analysis, and prioritized recommendations. Endpoint: https://mcp.nslookup.io/mcp
