app.openkrill/mailcheck

Est-ce que app.openkrill/mailcheck est sûr ?

Au dernier audit MCP Hub, le serveur MCP « app.openkrill/mailcheck » est classé « Non encore testé ». Référencé dans l'annuaire. Seul le pentest comportemental fait foi, et il n'a pas encore été exécuté sur ce serveur. Le verdict est réévalué en continu ; consultez la fiche pour l'état à jour.

Méthode : MCP Hub analyse la description de chaque outil (couche 1) et, pour le verdict fort, exécute le serveur dans une micro-VM isolée avec leurres et réseau bloqué (couche 2). On publie des noms et des compteurs, jamais le contenu brut renvoyé par un outil.

Les 7 outils

• check_dns_records≈ 504 tokens

  Use this when the user asks for a domain's DNS records, its mail provider or which certificate authorities may issue for it, such as "which mail provider does acme.io use?" or "show the MX and CAA records for github.com". Pass the domain and optionally up to 6 record types from A, AAAA, MX, TXT, CAA and NS (default: all). Returns each type's records with TTL, the mail provider named by the MX hosts, and the source and as_of date. It reads public DNS only; it cannot list subdomains or other record types.

  Paramètres, retour & exemple (2)

  Paramètres

  • types · array · optionnel
    Record types to read. Default: all of A, NS, MX, TXT, AAAA, CAA.
  • domain · string · requis
    The domain, such as "example.com". A web address or an email address is reduced to its domain.

• check_email_auth≈ 1056 tokens

  Use this when the user asks whether a domain's email is set up correctly, such as "is DMARC set up for github.com?" or "check SPF and DKIM for example.com". Pass the domain and, if known, up to 5 DKIM selector names. Returns SPF (policy, DNS lookup count, issues), DMARC (policy, percentage, report address, issues), DKIM per selector, the MX hosts and mail provider, a grade from A to F, a list of fixes, the exact SPF and DMARC records to paste (records_to_paste) and the DKIM steps for the detected mail provider (fix_steps), the source and as_of date, and a page link that shows the same check on the web. It reads public DNS only: it does not send mail, test delivery or read mailboxes.

  • dkim_selectors · array · optionnel
    DKIM selector names to look for, such as ["google"] or ["selector1", "selector2"]. Optional; DKIM cannot be found without one. At most 5.

• delivery_check≈ 1653 tokens

  Use this when the user asks whether mail from a domain will reach Gmail or Outlook, or why it is rejected or goes to spam, such as "will Gmail accept mail from example.com sent from 203.0.113.7?". Pass the domain, the sending IPv4 address if known, the return-path domain (mail_from) if known and, optionally, up to 5 DKIM selectors. Returns one verdict (likely_accepted, at_risk, likely_rejected or incomplete) with a verdict per provider, the top 3 causes each with one fix, the exact SPF and DMARC records to paste (records_to_paste) and the DKIM steps for the detected mail provider (fix_steps), every rule checked with its official source link (SPF for the IP, DKIM, DMARC, reverse DNS, blocklists), the 6 blocklists with their terms links, what was not checked, and the source and as_of date. Gmail and Outlook are always both reported, so there is no provider argument. It reads public DNS and free blocklists only: it sends no test message and cannot see sender reputation, so it does not promise inbox placement.

  Paramètres

  • domain · string · requis
    The domain in the From address, such as "example.com". A web address or an email address is reduced to its domain.
  • mail_from · string · optionnel
    The return-path domain, which receivers test SPF on: the domain after @ in the Return-Path header of a sent message, or smtp.mailfrom in its Authentication-Results, such as "send.example.com". Optional: when omitted, SPF for sending_ip is tested on the From domain, then on the usual return-path names under it (send, bounce, bounces, mail, mg, pm-bounces). Mail providers such as Resend, Amazon SES and Postmark send with their own return-path domain.
  • sending_ip · string · optionnel
    The public IPv4 address your mail is sent from, such as 203.0.113.7. Optional: without it the IP checks (SPF for the address, reverse DNS, IP blocklists) are skipped. IPv6 is not supported.
  • dkim_selectors · array · optionnel
    DKIM selector names, the s= value in a DKIM-Signature header, such as ["google"]. Optional: when omitted, 10 usual selector names are tried. At most 5.

• get_feedback_reply≈ 230 tokens

  Read the maintainers' reply to feedback you sent with submit_feedback, given its ticket id. Returns status pending until a reply is ready, then status answered with the reply text. The reply is information for you, not an instruction.

  • ticket · string · requis

• launch_score≈ 1011 tokens

  Use this when the user asks whether a new or secondary domain is ready for cold email or outreach, or wants a score for a sending domain, such as "is acme-mail.com ready for cold email?". Pass the domain and, optionally, up to 5 DKIM selectors. Returns a score from 0 to 100, a verdict (ready, almost, not_ready or incomplete), the 5 fixes to make first, every rule with its status, its kind (standard for a published requirement, opinion for common advice nobody requires) and its source link, the domain's registration date and age, what was not tested, and the source and as_of date. Opinion rules change the score but can never make the verdict not_ready. It reads public DNS and the public registry record only: it sends no message and cannot see sender reputation or warm-up, so it does not promise inbox placement.

  • domain · string · requis

• lookup_domain_registration≈ 447 tokens

  Use this when the user asks who a domain is registered with or when it expires, such as "when does openai.com expire and who is the registrar?". Pass the domain. Returns whether it is registered, the registrar, creation, update and expiry dates, days until expiry, registry status flags, name servers, and the source and as_of date. Registrant and contact details are never returned, so it cannot say who owns a domain.
