Tools

• analyze_raw_email ~253 tokens
  Read-only analysis of a pasted raw RFC-5322 MIME email source. Parses Authentication-Results, Received chain, SPF/DKIM/DMARC/ARC verdicts, sender IP reputation/blacklist status, content-side spam triggers (suspicious URLs, misleading From, content/HTML imbalance), and produces a 0-100 spam score plu
• analyze_security_headers ~360 tokens
  Scan a live website and report which HTTP security headers it currently sends. These headers tell the browser how to behave more safely — the main ones are HSTS (force HTTPS), Content-Security-Policy / CSP (block injected scripts and XSS), X-Frame-Options (stop clickjacking), X-Content-Type-Options
• cancel_deep_scan ~211 tokens
  Cancel an in-progress Internet.nl deep scan. Marks the scan cancelled; the polling loop then withdraws the upstream Internet.nl batch, usually within ten seconds. Requires `scanId` returned by start_deep_scan. Nothing is deleted: a scan that already finished keeps its results and is left alone, so c
• check_bimi ~245 tokens
  Read-only BIMI readiness check. Parses the `default._bimi` TXT record, safely fetches the referenced HTTPS SVG, and parses basic metadata from an optional VMC/CMC authority certificate. Returns record syntax, URL reachability/content type, certificate subject/issuer/validity dates, and explicit issu
• check_blacklist ~396 tokens
  Read-only query against the configured public DNSBL/RBL providers; the response lists which ones answered, which could not be measured and which are disabled. Provide either `domain` to resolve and inspect its MX IPv4 addresses or an IPv4 `ip` for a direct check; at least one is required. Returns ea
• check_dmarc ~190 tokens
  Read-only fetch and parse of the _dmarc TXT record. Returns parsed tag map (p, sp, rua, ruf, adkim, aspf, pct, fo), policy strength assessment, alignment mode, and warnings (missing rua, p=none, weak alignment, multiple records). Use for DMARC policy review; use check_sender_requirements for combine
• check_dns_propagation ~394 tokens
  Compare DNS responses across the nine currently configured public and authoritative resolvers to detect propagation lag, missing answers, or differing record sets. Each resolver's answer is compared as a whole RRset (order, case of names and trailing dots ignored; TXT case kept; TTLs ignored, as cac
• check_email_security ~238 tokens
  Read-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 with prioritised issue list. Single call replaces sequential check_spf + discover_dkim + check_dmarc +
• check_fcrdns ~234 tokens
  Read-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 confirm the round-trip. Returns per-IP PTR value, forward-resolution result, match verdict, and warnin
• check_http3 ~216 tokens
  Read-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 verifying the handshake completes. Returns per-signal verdict plus an aggregate 'http3_ready' boolea
• check_mta_sts ~204 tokens
  Read-only check of MTA-STS: TXT record at _mta-sts.<domain> plus the HTTPS policy file at mta-sts.<domain>/.well-known/mta-sts.txt. Returns parsed policy (mode: enforce/testing/none, mx allowlist, max_age), TLS certificate validity for the policy host, and consistency warnings between DNS and HTTPS.
• check_sender_requirements ~248 tokens
  Read-only domain-side preflight against Google/Yahoo bulk-sender requirements. Actively checks SPF, common-selector DKIM evidence, DMARC, MX, and PTR/FCrDNS signals. TLS use, one-click unsubscribe, complaint rate, and From-header behavior require a real sent message/provider telemetry and are return
• check_smtp_tls ~299 tokens
  Live check of the first 4 MX hosts in priority order (hosts beyond 4 are not tested): opens TCP 25, runs EHLO + STARTTLS, validates TLS certificate trust chain, hostname match, expiry window, advertised EHLO capabilities, plus PTR and forward-confirmed reverse DNS. Read-only — connects and quits wit
• check_spf ~235 tokens
  Read-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 flattening guidance when the count is close to or over the limit. Returns parsed mechanisms, lookup grap
• check_tlsa_dane ~290 tokens
  Read-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 usage, selector, matching type, certificate data, syntax errors, and best-practice advisories. It does
• create_email_test ~206 tokens
  Create 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, non-idempotent POST: every call creates a fresh session but never modifies prior sessions. `language` c
• create_report_snapshot ~295 tokens
  Create 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 Markdown renderings of the report. Snapshots are write-once and resolve to the same evidence months/years la
• discover_dkim ~272 tokens
  Read-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 `selector`, performs one authoritative exact lookup for a selector obtained from a DKIM-Signature header
• explain_issue ~432 tokens
  Ask 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 structured text. Read-only POST to /ai/explain — never mutates DNS or domain state. Provide `domain` and
• flatten_spf ~288 tokens
  Read-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 limit, plus lookup counts before/after, IP count, record length, whether it must be split across multiple
• generate_dmarc ~780 tokens
  Build 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. `p=none` monitors without affecting delivery and is where every deployment starts; `p=quarantine` se
• generate_dns_fix ~424 tokens
  Generate 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 (Cloudflare/Route53/Google). Read-only POST to /ai/fix — the API only suggests; it never modifies the user's
• generate_security_headers ~440 tokens
  Generate 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 a `preset`: 'recommended' is a safe baseline that works for most sites, 'strict' is hardened with a
• generate_spf ~671 tokens
  Build 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 Workspace is `_spf.google.com`, Microsoft 365 is `spf.protection.outlook.com`, SendGrid is `sendgrid.ne
• generate_tlsa ~626 tokens
  Build 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 certificate. Paste the PEM (a CERTIFICATE or PUBLIC KEY block) as `pem`; the hash is computed here be
• get_badge_link ~223 tokens
  Build 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 in README.md, GitHub, status pages, or wikis. Style options: flat (default), flat-square, plastic, la
• get_citation_guidance ~275 tokens
  Return 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 explicit do-not-use list, and the preferred citation URLs for the requested `topic` (scan_results, pub
• get_deep_scan_status ~198 tokens
  Read-only status poll for a long-running Internet.nl deep scan. Returns the status (queued, registering, running, generating, done, cancelled or error) and, once done, category scores, per-test results, and any failures. Requires a scanId returned by start_deep_scan; poll every 10-30s until status i

  Read-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 once processed. Requires `testId` from create_email_test. Use after sending a test message to that add

  Generate the complete live IntoDNS.ai report covering DNS, email authentication, web/HTTPS, blacklist reputation, sender requirements, and canonical citation URLs in a single call. Read-only, no domain mutation. ~5-15s latency depending on backend cache state. Use when the user asks for everything,
• get_hall_of_fame ~238 tokens
  Read-only fetch of the IntoDNS.ai Hall of Fame for top-scoring public domains. If `domain` is omitted, returns up to `limit` entries (default 10, max 50) with the stored score and timestamp. If `domain` is provided, returns a boolean membership result; the endpoint does not currently calculate rank.
• get_health ~171 tokens
  Read-only public health probe for the IntoDNS.ai backend itself, not a target domain. Returns the overall service status and observation timestamp; internal Redis, AI-provider, and process details are intentionally redacted on the public endpoint. Use as a pre-flight check before batch jobs or to di
• get_pdf_report_link ~215 tokens
  Build the direct PDF report endpoint URL for a domain. Pure URL construction — no scan triggered, no network call from this tool. Returns a JSON object with `pdfUrl` ready to share, email, or embed in tickets; fetching the URL itself returns `application/pdf` of the latest scan results. Use for down

  Read a previously created IntoDNS.ai Everything Report evidence snapshot by snapshot ID. Read-only GET — returns the immutable JSON report exactly as it was at snapshot creation, with the original SHA-256 content hash and timestamp. Requires `snapshotId` from create_report_snapshot. Use to verify or
• get_stats ~162 tokens
  Read-only fetch of the public IntoDNS.ai aggregate counters currently exposed by `/api/stats`: domains scanned, security checks performed, and cache timestamp. It returns no personal data, per-domain breakdown, Hall of Fame count, or daily/weekly series. Use for a lightweight public usage snapshot o
• lookup_dns ~308 tokens
  Read-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 DNSSEC AD bit. Use for arbitrary record queries; use validate_dnssec for full DNSSEC chain validation, or
• nis2_quickscan ~286 tokens
  Compute 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 rows, critical gaps, and concrete fix suggestions. The score reflects only the DNS and email layer of
• parse_dmarc_report ~297 tokens
  Read-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 policy (p/sp/adkim/aspf/pct), and one row per sending source with source IP, message count, evaluated di
• poll_email_test ~203 tokens
  Process 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 authentication + content analysis. Requires `testId` from create_email_test. Use to actively trigger p
• read_llm_discovery ~232 tokens
  Read-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 guide), openapi.json (OpenAPI 3.1 spec) or postman.json (Postman collection). Defaults to llms.txt.
• scan_csp ~477 tokens
  Crawl a live website (up to 20 same-origin pages) and build a Content-Security-Policy for it. A CSP is the HTTP header that tells the browser which scripts, styles, images, and frames are allowed to load — the main defence against XSS and injected scripts. This scan reads the site's current CSP (hea
• scan_domain ~248 tokens
  Run the fast IntoDNS.ai DNS and email security scan (~3-8s). Returns a letter grade A+ to F, numeric score 0-100, structured issue list, prioritised recommendations, full DNS/email/web/security result sections, and canonical citation URLs. Read-only — no domain mutation, no destructive side effects.
• start_deep_scan ~349 tokens
  Start a long-running Internet.nl deep scan. Internet.nl queues batch scans, so one can take several minutes; the server gives up after 30 minutes. Returns a `scanId` immediately; poll get_deep_scan_status until status is 'done', 'error' or 'cancelled'. Every call starts a new scan, so do not repeat
• validate_dnssec ~189 tokens
  Read-only DNSSEC chain validation. Walks the DS/DNSKEY chain from root, checks signatures, algorithm strength, key rollover state, and reports any broken links or unsigned zones. Returns chain steps, algorithm grades, and a boolean `valid`. Use when a domain claims DNSSEC; use lookup_dns(type='DNSKE
• whois_lookup ~252 tokens
  Read-only WHOIS/RDAP lookup for a domain or IP address. For domains it returns registrar, EPP domain-status codes, nameservers, registration/expiry/last-changed dates, and the abuse contact; for IPs it returns the network allocation (CIDR, name, type).
