scan_domainRun 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. The default tool for agent-visible scan evidence; use get_everything_report for a deeper single-shot report including web/blacklist/sender data, or start_deep_scan for slower Internet.nl-grade analysis. After running, use explain_issue or generate_dns_fix on any returned issue. No auth.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 rows, critical gaps, and concrete fix suggestions. The score reflects only the DNS and email layer of NIS2 — full NIS2 compliance also requires audit of web applications, supply chain, organisational processes, and training. Use when the user asks about NIS2 compliance, NIS2 readiness, NIS2 Article 21.2, cyber-hygiene compliance, or related EU-NIS regulation checks for a domain.get_everything_reportGenerate 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, the full picture, or a deep current-state summary; use scan_domain for a faster default scan, or create_report_snapshot when the result must remain immutable for audit/ticket use. No auth, no side effects.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 Markdown renderings of the report. Snapshots are write-once and resolve to the same evidence months/years later — useful for tickets, audit trails, NIS2/ISO compliance evidence, and LLM citations that should not drift. A canonical POST creates one snapshot per call (additive and not idempotent); use get_report_snapshot to read it back. Use this instead of get_everything_report when the result must remain stable.get_report_snapshotRead 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 re-read an audit-trail evidence record without re-running a live scan; use get_everything_report for current live data instead. No auth, fully idempotent.start_deep_scanStart a long-running Internet.nl deep scan (typically 30-120s). Returns a `scanId` immediately; poll get_deep_scan_status until status='finished'. Read-only — no domain mutation. Internet.nl runs an exhaustive standards-compliance audit (IPv6, DNSSEC, modern TLS, RPKI, mail authentication) used by EU governments. Use when scan_domain output is not strict enough for compliance reporting, or when the user asks for an Internet.nl-grade audit. For sub-10s answers, use scan_domain. To abort an in-progress scan, call cancel_deep_scan. No auth.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 start_deep_scan; poll every 10-30s until status='finished'. Use after start_deep_scan; for fast single-vantage scans, prefer scan_domain. No auth, no side effects.cancel_deep_scanCancel 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 calling this twice is safe. An unknown or expired scanId returns 404. Use when the user changes their mind mid-scan or when polling get_deep_scan_status would otherwise time out. No auth.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 DNSSEC AD bit. Use for arbitrary record queries; use validate_dnssec for full DNSSEC chain validation, or check_dns_propagation for multi-resolver consensus. No auth, no rate limits beyond upstream resolver.validate_dnssecRead-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='DNSKEY') for raw key data only. Single HTTP GET, no auth, no destructive actions.check_dns_propagationCompare DNS responses across the nine currently configured public and authoritative resolvers to detect propagation lag, missing answers, or inconsistent TTL/data values. Defaults to record type A and region 'all'. Returns every resolver response plus a propagation percentage and explicit inconsistency list. Use when records were just changed and you suspect staleness; for a single DNS-over-HTTPS lookup use lookup_dns instead. Read-only HTTP, no auth, and no destructive actions.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 usage, selector, matching type, certificate data, syntax errors, and best-practice advisories. It does not fetch or cryptographically match the live service certificate, so pair it with check_smtp_tls for SMTP certificate evidence. Use before publishing DANE records or troubleshooting DANE handover. No auth or destructive actions.domain_reportQuery 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.audit_domainPerform 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 tokens), Pro: 500/hr. Returns {domain, report, technologies, live_headers, summary, next_calls}.contrast_scanActive website security scan: runs the ContrastScan C engine (11 modules — HTTP security headers, SSL/TLS, DNS, redirect chain, information disclosure, cookie flags, DNSSEC, HTTP methods, CORS, HTML hygiene, deep CSP analysis) against the live site and enriches the raw result with severity-ranked vulnerability findings and a letter grade. Use for a hands-on misconfiguration scan; use audit_domain for passive recon (DNS/WHOIS/SSL/threat intel) and scan_headers for headers only. Active outbound fetch — a per-target eTLD+1 throttle (60 req/min) applies. Free: 30/hr (costs 6 tokens), Pro: 500/hr. Returns {domain, resolved_ip, total_score, max_score, grade, findings, findings_count, headers, ssl, dns, redirect, disclosure, cookies, dnssec, methods, cors, html, csp_analysis, enterprise, summary, next_calls}.tech_stack_cve_auditComposite tech-stack + CVE audit (MCP-only, no REST endpoint). Detects technologies on the target domain, queries CVE database for known vulnerabilities per product, enriches top-10 CVE candidates with CISA KEV federal patch deadlines, and checks public exploit / PoC availability. Identical for every tier — all data is sourced from local DB mirrors (no Shodan/AbuseIPDB), so there is no tier gating. CVE candidate batch: 50. Cost: 10 tokens per call — Free 30/hr ≈ 3 audits, Pro 500/hr ≈ 50 audits. Returns {domain, technologies, cves_by_tech, kev_findings, exploit_findings, summary, next_calls}.Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.

threat_reportQuery comprehensive threat profile for an IP: Shodan host data, AbuseIPDB reputation, ASN/geolocation, and open ports. Use for IP investigation and SOC alert triage; for domain data use domain_report. Note: nested asn block always returns at most 50 IPv4/IPv6 prefixes — call asn_lookup with include_full_prefixes=True for the full announced-prefixes list. enrichment.vulns is severity-aware list[VulnInfo] (cve_id + severity + cvss_v3) — Phase 2 v1.16.0 BREAKING; pre-1.16 it was list[str] of CVE IDs. Free: 30/hr (costs 6 tokens), Pro: 500/hr. Returns {ip, enrichment, abuseipdb, shodan, asn, threat_level}.dns_lookupQuery all DNS record types (A, AAAA, MX, NS, TXT, CNAME, SOA) for a domain. Use for mail routing inspection, nameserver verification, or SPF/DMARC checks; for full overview use domain_report. TXT records are returned raw (no filter) — `total_txt_records` always carries the honest count (use domain_report for the security-only filtered TXT view). Free: 30/hr, Pro: 500/hr. Returns {domain, records: {a, aaaa, mx, ns, txt, total_txt_records, cname, soa}, summary}.whois_lookupRetrieve WHOIS registration data: registrar, creation/expiry dates, nameservers, status. Use to verify domain ownership, age, expiration; for full audit use domain_report. Free: 30/hr, Pro: 500/hr. Returns {domain, whois: {registrar, creation_date, expiry_date, updated_date, name_servers, status, raw_length, error}, summary}.ssl_checkAnalyze SSL/TLS certificate: grade (A/B/C/D/F), protocol version, cipher suite, chain, expiry, Subject Alternative Names, and structured validation findings. Invalid certs (expired, self-signed, hostname mismatch, untrusted root) are reported as findings via valid=false + validation_errors[] rather than as endpoint failures, so an unreachable cert still returns useful intel. Grade D = cert readable but invalid; F = expired, legacy TLS, or probe failure. Use to audit certificate validity and detect expiring certs; for full domain audit use audit_domain. Free: 30/hr, Pro: 500/hr. Returns {grade, valid, validation_errors, protocol, cipher, issuer, subject, not_before, not_after, days_remaining, chain, san, warnings}.subdomain_enumDiscover subdomains using passive methods: Certificate Transparency logs + DNS brute-force (no active probing). Use to map organization's attack surface; non-intrusive. Response carries next_calls — capped at 5 ssl_check hints (one per first-five subdomain) so triage scales to large enumerations without token bloat; pull tail entries by name when needed. Free: 30/hr, Pro: 500/hr. Returns {domain, count, subdomains, sources, found_via_wordlist, found_via_crtsh, wildcard_status, crtsh_status, warnings, summary, next_calls}. Always check wildcard_status FIRST: 'absent' means the DNS brute-force plane was meaningful; 'present' means the zone answers every name (wildcard DNS) so wordlist results were discarded and count is a certificate-transparency LOWER BOUND — report the surface as UNKNOWN, not small, and never infer low exposure from it; 'undetermined' means a negative-control probe went unanswered, so count is unverified. Then check crtsh_status: 'ok' means the CT lookup completed (so a low count is real); 'timeout' / 'rate_limited' / 'unavailable' / 'error' means CT logs did not respond and the count is wordlist-only — the actual attack surface is likely larger, retry later or surface the limitation to the user.tech_fingerprintDetect website technology stack: CMS, frameworks, CDN, analytics tools, web servers, languages (via HTTP headers + HTML analysis). Use for passive reconnaissance; for full audit use audit_domain. Free: 30/hr, Pro: 500/hr. Returns {technologies: [{name, category, confidence%, version}]}.threat_intelCheck domain against abuse.ch URLhaus for known malware-distribution URLs (single source — for multi-feed correlation use ioc_lookup which adds ThreatFox and, for IPs, Feodo Tracker). Use for fast domain-level threat assessment; use phishing_check for specific URLs. Free: 30/hr, Pro: 500/hr. Returns {malware_urls, threat_tags, threat_status, summary}.wayback_lookupRetrieve Wayback Machine snapshots for a domain: first capture, latest, total count, snapshot list. Use to investigate domain history and age; for full audit use domain_report. Free: 30/hr, Pro: 500/hr. status='ok' means the count is authoritative (even when 0 → confirmed no archives). status='unavailable' means CDX timed out/rate-limited/5xx — total_snapshots is OMITTED (unknown, NOT zero) and the agent should NOT report "no snapshots"; the warnings[] array carries the cdx_* error code (cdx_timeout/cdx_rate_limited/cdx_unavailable/cdx_error/cdx_parse_error/cdx_body_too_large). Heavy domains (kernel.org, microsoft.com, archive.org itself) frequently time out the CDX endpoint despite having millions of snapshots — fall back to archive_url for manual inspection. Returns {domain, status, total_snapshots, first_seen, last_seen, years_online, snapshots, archive_url, summary, warnings}.
