Domainee MCP server

• tools_cname_lookupFree

  Free public API. Resolve a hostname's CNAME chain. Useful for debugging custom-domain CNAME setups.

• tools_dkim_record_checkerFree

  Free public API. Look up the DKIM record at <selector>._domainkey.<domain>, parse the public key, flag issues.

• tools_dmarc_record_checkerFree

  Free public API. Look up the DMARC record at _dmarc.<domain>, parse policy/alignment/reporting tags, flag missing or too-permissive settings.

• tools_dns_propagation_checkerFree

  Free public API. Query the same hostname across ~10 public DNS resolvers worldwide and report which ones return the same answer. Useful right after a DNS change.

• tools_dns_provider_lookupFree

  Free public API. Identify which DNS provider actually serves a domain, fingerprinted from its public NS records. Returns the record name written the way that provider's form expects it (providers disagree about whether the apex is '@', blank, or the full domain, and getting it wrong is the most common way a correct record lands in the wrong place), whether the provider can point a zone apex at a hostname, where its record editor lives, and the provider-specific settings that silently break custom domain setups. Use this before telling someone what DNS record to add. No Bearer required.

• tools_dns_record_lookupFree

  Free public API. Look up DNS records (A, AAAA, CNAME, MX, TXT, NS, SOA) for any domain.

• tools_domain_age_checkerFree

  Free public API. Returns a domain's registration date, age in days + years, last-updated date, and expiration.

• tools_domain_availability_checkerFree

  Free public API. Check availability of a name across one or more TLDs. Pass a `name` (no TLD) and an optional `tlds` array.

• tools_domain_connect_checkerFree

  Free public API. Check whether a domain's DNS provider implements the Domain Connect protocol, read live from the _domainconnect TXT record and the provider's settings endpoint. Reports the provider and whether it offers the synchronous flow (a signed redirect with no token exchanged, the one that works in practice) or only the asynchronous OAuth flow. Note that provider support is necessary but not sufficient for one-click setup: the service being connected must also have a template the provider has synced and enabled, which many providers do only after a per-service onboarding. No Bearer required.

• tools_http_header_checkerFree

  Free public API. Fetch a URL and return its response headers + security grade based on common security headers.

• tools_redirect_checkerFree

  Free public API. Follow a URL's redirect chain and return every hop with status code, response time, final destination.

• tools_reverse_ip_lookupFree

  Free public API. Reverse-DNS (PTR) lookup for an IP address. Returns one or more hostnames if configured.

• tools_spf_record_checkerFree

  Free public API. Look up and validate the SPF record for a domain. Counts void/total DNS lookups, flags syntax issues, validates against RFC 7208's 10-lookup limit.

• tools_ssl_checkFree

  Free public API. Check the TLS certificate of any public hostname. Returns issuer, subject, validity dates, days until expiry, full chain, cipher, protocol, and SAN list. No Bearer required.

• tools_subdomain_finderFree

  Free public API. Enumerate subdomains for a target domain via Certificate Transparency logs + DNS resolution.

• tools_txt_record_lookupFree

  Free public API. Fetch all TXT records on a domain, classifying each as SPF, DKIM, DMARC, BIMI, verification token, or general.

• tools_website_status_checkerFree

  Free public API. Check if a website is up or down. Returns HTTP status, response time, final URL after redirects, basic SSL info.

• tools_whois_lookupFree
