bulk_threat_checkCheck up to 100 domains or IPv4 addresses at once against ThreatCluster's high-confidence 30-day IOC feed; each domain is resolved and its IPv4 matched too.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Check up to 100 domains or IPv4 addresses at once against ThreatCluster's high-confidence 30-day IOC feed; each domain is resolved and its IPv4 matched too. IOC only (no ransomware-claim lookups; use threat_check for one domain). Stale feed returns an error and is not charged. Costs $0.50 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
Annotations the server declares
- readOnlyHint: true
- openWorldHint: true
- destructiveHint: false
- idempotentHint: true
check_certCheck the TLS certificate of one hostname: issuer, validity dates, days left, % of lifetime used, renewal cadence and a renewal-stall flag, plus a live HTTPS pass/fail probe.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Check the TLS certificate of one hostname: issuer, validity dates, days left, % of lifetime used, renewal cadence and a renewal-stall flag, plus a live HTTPS pass/fail probe. Use it when you only need certificate health; use site_health for cert + DNS + expiry together, or domain_grade for a scored A-F result. Certificate details come from public Certificate Transparency logs (Cert Spotter, crt.sh fallback), not from the live connection, so a brand-new cert may not show yet. Read-only; makes one HTTPS request to the host and one CT-log query, usually 1-5 s. Costs $0.01 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
Annotations the server declares
- readOnlyHint: true
- openWorldHint: true
- destructiveHint: false
- idempotentHint: true
check_dnsLook up the live DNS of a domain: NS, A/AAAA/CNAME, MX, SPF, DMARC, CAA (climbing to the parent zone) and DNSSEC status, with plain-English findings.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Look up the live DNS of a domain: NS, A/AAAA/CNAME, MX, SPF, DMARC, CAA (climbing to the parent zone) and DNSSEC status, with plain-English findings. Use it for a DNS inventory or to debug resolution; use check_email_auth for a deeper SPF/DMARC/DKIM/MTA-STS review. Queries Cloudflare DNS-over-HTTPS (1.1.1.1) at call time; read-only, nothing is stored. Costs $0.01 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
Annotations the server declares
- readOnlyHint: true
- openWorldHint: true
- destructiveHint: false
- idempotentHint: true
check_domain_expiryCheck when a domain registration expires: registrar, registered and expiry dates, days left, EPP status codes and nameservers, from the registry's RDAP server.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Check when a domain registration expires: registrar, registered and expiry dates, days left, EPP status codes and nameservers, from the registry's RDAP server. Use it for renewal risk on the registered domain (not the certificate; use check_cert for that). Some TLDs publish no RDAP service, in which case found=false explains why. Read-only. Costs $0.01 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
Annotations the server declares
- readOnlyHint: true
- openWorldHint: true
- destructiveHint: false
- idempotentHint: true
check_email_authReview the email authentication setup of a domain: SPF validity and DNS-lookup count (limit 10), DMARC policy, pct and reporting, DKIM on common selector names, MTA-STS mode, TLS-R…No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Review the email authentication setup of a domain: SPF validity and DNS-lookup count (limit 10), DMARC policy, pct and reporting, DKIM on common selector names, MTA-STS mode, TLS-RPT and BIMI, with a rough 0-100 score and plain-English fixes. Use it before sending mail from a domain or when mail lands in spam. DKIM is only checked on common selectors, so "not found" is not proof DKIM is missing. Live DNS via Cloudflare DoH; read-only, no email is sent. Costs $0.01 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
Annotations the server declares
- readOnlyHint: true
- openWorldHint: true
- destructiveHint: false
- idempotentHint: true
check_security_headersCheck the HTTP security headers of a website with one live HTTPS GET: redirect chain (up to 5 hops), final status, HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Poli…No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Check the HTTP security headers of a website with one live HTTPS GET: redirect chain (up to 5 hops), final status, HSTS, CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy and COOP, with a simple A-F header grade and findings. Use it for web-hardening checks; it is not a vulnerability scan. The page body is not read or stored. Costs $0.01 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
Annotations the server declares
- readOnlyHint: true
- openWorldHint: true
- destructiveHint: false
- idempotentHint: true
domain_gradeGrade a domain's security posture A-F in one call, for vendor-risk or due-diligence checks.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Grade a domain's security posture A-F in one call, for vendor-risk or due-diligence checks. Runs the TLS, DNS (DNSSEC, CAA), registration-expiry, email-auth and HTTP-header checks and returns one letter, a 0-100 score, points per category (TLS 25, email 25, headers 20, DNS 15, registration 15) and the top fixes. Use it when you want a verdict; use site_health or the single checks when you need raw data. Unavailable categories are left out of the percentage (partial=true). Read-only; takes about 3-10 s. Costs $0.03 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
Annotations the server declares
- readOnlyHint: true
- openWorldHint: true
- destructiveHint: false
- idempotentHint: true
full_site_auditFull site audit report for one domain, for client reports, vendor reviews or a pre-launch check.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Full site audit report for one domain, for client reports, vendor reviews or a pre-launch check. Runs every check (TLS from CT logs + live probe, DNS/DNSSEC/CAA, registration expiry and transfer lock, SPF/DMARC/DKIM/MTA-STS, security headers) plus HTTP->HTTPS redirect, www/apex consistency, RFC 9116 security.txt, robots.txt and sitemap. Returns the A-F grade and score (same weights as domain_grade), an action plan sorted critical > high > medium > low where each item has the exact fix and effort, and every raw section. Use domain_grade for just the letter. Fails (not charged) if 3+ core checks fail. Read-only; about 5-15 s. Costs $2 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
Annotations the server declares
- readOnlyHint: true
- openWorldHint: true
- destructiveHint: false
- idempotentHint: true

  annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The description's first verb is "run": a word for a change.
  What this check looks for
Description, as the server wrote it
Run check_cert, check_dns and check_domain_expiry together and return their raw results plus a short summary, the renewal-stall flag and the Let's Encrypt 64-day certificate note (from 2027-02-10). Use it for a full data dump in one call; use domain_grade if you want a single scored A-F answer that also covers email auth and HTTP headers. If one or two sources fail you get partial=true with the rest. Read-only. Costs $0.03 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.

Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Is this domain known-bad? Resolves the hostname (A/AAAA), matches the name, its parent domains and resolved IPv4 against ThreatCluster's high-confidence 30-day IOC feed (cached, refreshed about hourly), and looks up ransomware leak-site claims naming the domain (commercially reusable sources via Dragons Eye). Returns verdict listed, claimed, listed_and_claimed or no_known_threat with the matching reports. No match is not proof of safety; claims are unverified attacker assertions. Stale feed or source failure returns an error and is not charged. Costs $0.02 USDC per call via x402 (payment goes in _meta["x402/payment"]); invalid input or an upstream failure returns an error and is not charged.
