Checker MCP vs Intodns MCP Server

nis2_quickscan

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 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_report

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, 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_snapshot

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 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_snapshot

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 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_scan

Start 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_status

Read-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_scan

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 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_dns

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 check_dns_propagation for multi-resolver consensus. No auth, no rate limits beyond upstream resolver.

validate_dnssec

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='DNSKEY') for raw key data only. Single HTTP GET, no auth, no destructive actions.

check_dns_propagation

Compare 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_dane

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 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.
