What it can do

  • Check Email Security: Email Security score for a domain with the DNS records found and the exact records to publish for each fix.
  • Check Discoverability: Discoverability score for a domain: crawl access, site plumbing, page metadata, structured data and answer-engine readiness, with the exact file or tag to fix for each finding.
  • Get Report: Both scores, the open fixes ranked by severity, and the shareable report link. Use this first for "is my domain set up right?" questions.

What data it sees

No: the server works without sign-in

Email security and AI discoverability scores for any domain, with the exact record or tag to fix.

Ask about any domain and get two scores out of 100. Email Security covers MX, SPF, DKIM and DMARC, including whether DMARC is actually enforced; every finding comes with the exact TXT record to publish. Discoverability covers what search engines and AI crawlers can get from the site: robots.txt rules for Googlebot, Bingbot, GPTBot, ClaudeBot, OAI-SearchBot and PerplexityBot, CDN blocks at the edge, the sitemap, www/apex redirects, canonical tags, titles and descriptions, Organization and WebSite structured data, llms.txt, and whether the opening paragraphs define the brand.

Tools: get_report (both scores and ranked fixes), check_email_security, check_discoverability, fetch_as_crawler (the exact response a named crawler receives), verify_fix (re-check one area after a change).

No account or key needed. The server reads public DNS and public pages only and writes nothing. Results are cached and shared; fresh scans are rate-limited per domain.
