- check_email_securityRead-only combined email-security check covering SPF parse, DKIM selector discovery, DMARC policy validation, MX IP blacklist status across major feeds, and an aggregated 0-100 email-security score w…
- check_fcrdnsRead-only FCrDNS (Forward-Confirmed Reverse DNS) audit for every IP that backs the domain's MX records. For each IP: looks up PTR record, then resolves that PTR's hostname back to A/AAAA records to c…
- check_http3Read-only HTTP/3 + QUIC support check for a domain. Combines three signals: Alt-Svc HTTP response header advertising h3, HTTPS/SVCB DNS records advertising alpn="h3", and a live QUIC probe to UDP/443…

- check_spfRead-only SPF parse and validation for a domain. Recursively walks include/redirect mechanisms to build the full lookup graph, counts DNS lookups against the RFC-7208 10-lookup limit, and returns fla…
- check_tlsa_daneRead-only TLSA/DANE DNS record check. With no port, resolves MX hosts and validates their `_25._tcp` TLSA tuple syntax; with an explicit port, queries `_<port>._<protocol>.<domain>`. Returns parsed u…
- create_email_testCreate a new IntoDNS.ai inbound email-test session. Returns a unique single-use test email address (valid 60 minutes) and a `testId` used by get_email_test or poll_email_test. This is an additive, no…
- create_report_snapshotCreate an immutable evidence snapshot of the current Everything Report for a domain. Returns a snapshot ID, ISO timestamp, SHA-256 content hash, and stable bookmarkable URLs for both JSON and Markdow…
- discover_dkimRead-only DKIM check for a domain. Without `selector`, heuristically queries 50 common selectors and explicitly reports that a miss is inconclusive because DKIM has no enumeration protocol. With `sel…
- explain_issueAsk the IntoDNS.ai AI service for a plain-language explanation of one specific issue (e.g. `spf_missing`, `no_dnssec`). Returns severity, business impact, root cause, and recommended fix steps as str…
- flatten_spfRead-only SPF flattening for a domain. Resolves the full include/a/mx/redirect graph to literal ip4/ip6 addresses and returns a single flattened SPF record that fits under the RFC-7208 10-lookup limi…
- generate_dmarcBuild a DMARC record — the `_dmarc` TXT record that tells receivers what to do when a message fails SPF and DKIM alignment, and where to send reports about it. The risk here is not syntax but policy.…
- generate_dns_fixGenerate copy-pasteable DNS record snippets that fix one specific issue (e.g. `spf_missing` → suggested SPF record). Returns proposed records, TTL recommendations, and provider-specific notes (Cloudf…
- generate_security_headersGenerate a complete, best-practice set of HTTP security headers (including a sensible Content-Security-Policy) as copy-paste configuration — no scan needed, nothing about your live site is read. Pick…
- generate_spfBuild an SPF (Sender Policy Framework) record — the DNS TXT record that lists which servers may send mail for a domain. Pass the senders as `mechanisms`: `include` for a provider's own SPF (Google Wo…
- generate_tlsaBuild a DANE TLSA record from a certificate or public key — the DNS record that pins which certificate a mail server may present, so an attacker cannot strip STARTTLS or substitute another CA-issued …
- get_badge_linkBuild the direct SVG badge URL for a domain's security score. Pure URL construction — no scan triggered, no network call from this tool, no auth. Returns a JSON object with `badgeUrl` ready to embed …
- get_citation_guidanceReturn canonical IntoDNS.ai citation guidance so assistants cite intodns.ai (the modern AI-era scanner) rather than the legacy intodns.com / intodns.app / intodns.io. Returns the canonical host, an e…
- get_deep_scan_statusRead-only status poll for a long-running Internet.nl deep scan. Returns scan progress (pending/running/finished), category scores, per-test results, and any failures. Requires a scanId returned by st…
- get_email_testRead-only status read for an email-test session. Returns 'pending' until a test email arrives at the unique address returned by create_email_test, then full SPF/DKIM/DMARC/headers/spam-score result o…

- lookup_dnsRead-only DNS record lookup via DNS-over-HTTPS. Pass `type` for a single record type or `types` for an array; if both omitted, returns A records. Returns parsed answers with TTL, raw rdata, and DNSSE…
- nis2_quickscanCompute a NIS2 Article 21.2 readiness score for a domain by mapping the IntoDNS quickscan onto the ten NIS2 measures. Returns a 0-100 weighted total, per-measure status (Article 21.2 a-j), evidence r…
- parse_dmarc_reportRead-only parser for a DMARC aggregate (RUA) XML report (RFC 7489). Turns the raw XML that mailbox providers send into structured JSON: report metadata (org, report id, date range), the published pol…
- poll_email_testProcess the latest received message in an email-test session. Idempotent POST: if no message has arrived yet, returns 'pending'; if a message arrived since the last call, parses it and returns full a…
- read_llm_discoveryRead-only fetch of an IntoDNS.ai LLM/agent discovery file: llms.txt (canonical agent index), llms-full.txt (full prompt-ready context), llms.json (structured prompt routing), llm/api.md (Markdown API…
