"MTA" matching MCP tools:

• dossier_mta_sts

  drwho.me developer tools

  Core dossier check: Fetch and validate a domain's MTA-STS policy (mode, mx, max_age, policy id). Use to confirm inbound SMTP is locked to TLS for this domain. Resolves the _mta-sts TXT record, then fetches the policy from mta-sts.<domain>/.well-known/mta-sts.txt; 10s timeout. Returns a CheckResult; not_applicable when no MTA-STS TXT is published.

• audit_domain

  ContrastAPI

  Perform comprehensive domain audit: combines domain_report + live HTTP security headers + technology fingerprinting. By default report.dns.txt is filtered to security-relevant entries (SPF, DMARC, DKIM, MTA-STS, TLS-RPT) and report.dns.total_txt_records reports the honest pre-filter count; pass include_all_txt=true for the raw TXT list. Use when you need the full picture (recon + active checks); use domain_report for passive-only assessment. Response carries next_calls — chain with subdomain_enum (always emitted) and ssl_check (when an A record resolves) for the residual recon depth (tech_fingerprint already inline as `technologies`). Free: 30/hr (costs 6 credits), Pro: 500/hr. Returns {domain, report, technologies, live_headers, summary, next_calls}.

• dns_check_txt

  DMARKOFF — DMARC, SPF & DKIM Analytics

  Live TXT DNS lookup — queries ALL TXT records for a domain in real time and returns each record with its TTL and detected type (spf, dmarc, mta-sts, tlsrpt, bimi, other). Does NOT require a project — works for any domain, even ones not monitored. This is the only tool that shows all TXT records at once, making it essential for: • Detecting duplicate SPF records (multiple "v=spf1..." entries — a common misconfiguration that causes SPF to fail) • Verifying a newly published DNS record is visible • Checking for conflicting or stale TXT entries • Diagnosing issues that other tools (get_spf_records, get_dkim_records) cannot catch because they only see DMARC-reported data, not raw DNS.

• domain_report

  ContrastAPI

  Query DNS, WHOIS, SSL, subdomains, and threat intel for a domain in one call. By default dns.txt is filtered to security-relevant entries (SPF, DMARC, DKIM, MTA-STS, TLS-RPT) and dns.total_txt_records reports the honest pre-filter count; pass include_all_txt=true for the raw TXT list. Use as a starting point for domain investigations; use audit_domain for live headers + tech stack. Response carries next_calls — chain with subdomain_enum (always emitted), ssl_check + tech_fingerprint (when an A record resolves) for the standard recon depth without re-prompting. Free: 30/hr, Pro: 500/hr. Returns domain report with DNS records, WHOIS data, SSL cert, risk score, email config, threat status, recommendation, and next_calls.

• e-stat-get-meta-info

  e-Stat MCP

  e-stat-get-stats-list ツールで取得した統計表IDに基づいて、メタ情報（分類項目、地域区分、時間軸、表章事項などの構造情報）を取得する。統計データの項目構成や取得可能な条件値を把握するために使用する。

• dns_health

  nslookup

  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.
