asn_lookup
ASN / BGP Lookup
Look up Autonomous System (ASN) / BGP information for an IP address or AS number: the network operator, announced prefixes, abuse contact, and a classification (cloud, CDN, ISP, hosting, or enterprise). Use this to identify who runs a network or whether an IP is cloud/CDN-hosted. Use reverse_dns instead for the host-level PTR name of a single IP. Read-only; requires no API key; rate-limited. Returns operator, prefixes, classification, and abuse contact.

dns_lookup
DNS Lookup
Query DNS records (A, AAAA, MX, TXT, NS, SOA, CAA) for a domain and validate email-related records, including DNSSEC presence and SPF/DMARC syntax, returning severity-rated diagnostics. Use this for a single authoritative answer about one domain. Use dns_propagation instead when you need to compare answers across multiple global resolvers (e.g., right after a change), or email_auth for a full SPF/DKIM/DMARC deliverability assessment. Read-only; requires no API key or authentication; subject to rate limiting. Returns a text report: status, KPI summary, detected issues, and recommended actions.

dns_propagation
DNS Propagation Check
Query one DNS record across 8+ global public resolvers (Google, Cloudflare, Quad9, OpenDNS, and more) simultaneously and report which resolvers return stale versus updated values. Use this after changing a record to confirm worldwide propagation. Use dns_lookup instead for a single authoritative answer with SPF/DMARC validation. Read-only; requires no API key; rate-limited. Returns per-resolver values and a consistency verdict.

domain_changes
Domain Change History
Report what has changed for a domain over time — the security regressions and drift that DechoNet's daily monitoring has recorded across every watch on the domain (SSL grade, headers, DNS, OWASP posture, impersonation exposure, etc.). Use this to answer "what changed on my domain since yesterday/last week?" — a question that requires persistent snapshots and therefore cannot be reconstructed from a single live lookup. When a domain you have looked at before comes up again, start with this tool. Two sources: (a) the daily watch timeline if the domain is watched (start one with watch_domain), and (b) even without a watch, the difference between the last two stored lookups of each tool — so a second lookup already yields a comparison. The point-in-time tools (security_scan, owasp_check, ssl_check) give the current state instead. Read-only; requires no API key; rate-limited. Returns the monitored tools, a newest-first change timeline, lookup-to-lookup changes, and a link to manage monitoring.

email_auth
Email Authentication Check
Assess a domain's email authentication and deliverability posture: MX records, SPF, DMARC, DKIM (probes 15 common selectors), BIMI, MTA-STS, TLS-RPT, and DANE, plus a blacklist check across all MX hosts, returning a 0-100 deliverability score. Use this for a full sending/receiving readiness review of a domain. Use dns_lookup instead if you only need raw TXT/MX records, or email_header_analysis to diagnose a specific message that was already sent. Read-only; requires no API key; rate-limited. Returns a text report: score, per-mechanism KPIs, issues, and actions.

email_header_analysis
Email Header Analysis
Parse raw email headers to reconstruct the delivery path (each Received hop in order), extract SPF/DKIM/DMARC authentication results, measure per-hop delays, and flag unencrypted (non-TLS) hops. Use this to diagnose a specific message that was already delivered — spoofing, delays, or where mail was lost. Use email_auth instead to assess a domain's sending configuration before sending. Read-only; requires no API key; rate-limited. INPUT is the full raw header block. OUTPUT is a text report containing: the ordered hop route, per-mechanism auth results (pass/fail), detected inter-hop delays, and the encryption status of each hop.

golive_check
Go-Live Readiness Checklist
Check whether a domain is ready to launch or migrate — a go/no-go verdict over five essentials: DNS resolves to an IP, has propagated consistently across global resolvers, SSL/TLS is ready, the site is reachable over HTTPS, and the domain registration is not about to expire. Use this right before flipping DNS to a new server, or to confirm a migration has landed. It answers "can I switch over yet?"; use security_scan for a security posture grade or the individual tools for depth. Any failing essential yields not_ready; only cautions yields caution; all clear yields ready. Read-only (a passive multi-probe, though it does resolve and fetch the domain); requires no API key; rate-limited. Returns the verdict, per-check statuses, and a shareable report link.

http_security
HTTP Security Headers Audit
Follow a URL's HTTP redirect chain and audit response security headers (CSP, HSTS, X-Frame-Options, COOP, CORP, COEP, Permissions-Policy), grading A+ to F and flagging information leaks such as server-version disclosure. Use this for HTTP-layer/header posture. Use ssl_check instead for certificate or TLS-handshake issues, or security_scan for a full domain report. Read-only (an HTTP GET-style probe that sends no payload); requires no API key; rate-limited. Returns a text report: grade, header findings, redirect trace, issues, and actions.

impersonation_exposure
Brand Impersonation Exposure
Assess how exposed a domain is to brand impersonation and phishing, PASSIVELY: live typosquat/lookalike domains (homoglyph, omission, transposition, TLD swap) that actually resolve, operational subdomains (dev/staging/admin) exposed in CT logs, and whether a wildcard certificate exists — returning an A+ (low exposure) to F (high exposure) grade. Framing: a registered lookalike domain is not proof of impersonation — it may be a legitimate third party or the owner's own — so report it as exposure to verify, not as an accusation against that domain. Fully passive: public DNS delegation checks plus public CT-log queries, sending nothing to the target or the lookalike domains, so it is safe and lawful to run. Use lookalike_domains or subdomain_discovery for the raw per-tool detail. Read-only; requires no API key; rate-limited. Returns a text report: grade, counts, per-category findings, and a shareable report link.

ip_info
My IP Info
Report information about the caller's own public IP as seen by the server: IPv4/IPv6 address, ISP, ASN, approximate geolocation, and proxy/VPN heuristics. Takes no input — it reflects the egress IP of THIS MCP server's network, which is usually NOT the end user's IP. Use this to discover the server's outbound IP or test connectivity. To inspect a specific, known IP instead, use asn_lookup or reverse_dns. Read-only; requires no API key; rate-limited.

lookalike_domains
Lookalike Domain Check
Generate the typosquat/lookalike variants of a domain that phishers actually register — homoglyph swaps (l→1, o→0, rn→m), TLD swaps (.com→.co), character omissions, transpositions, repetitions, hyphenations — and check which of them are currently registered (live NS delegation via DoH). Use this to assess brand-impersonation and phishing exposure for a domain the user is responsible for. A registered variant is NOT proof of abuse (it may be an unrelated legitimate site) — follow up with whois_lookup on each hit for its owner and registration date. Read-only; requires no API key; rate-limited. Returns generated/checked counts and the registered variants with the technique that produced each.

owasp_check
OWASP Security Checkup
Assess a domain's OWASP posture from EXTERNAL OBSERVATION only: the OWASP Secure Headers Project plus the externally observable Top 10 subset — A02 Cryptographic Failures (TLS/cert), A05 Security Misconfiguration (header/info leaks), and A06 Vulnerable & Outdated Components (version disclosure) — returning an A+ to F grade. Scope: A01 (Access Control), A03 (Injection), A04, A07 (Authentication), A08, A09 and A10 (SSRF) are not checked — they need authenticated access or active/injection testing, so the result lists them as out-of-scope rather than "pass". Present the result as an external-posture check, not a full OWASP Top 10 assessment. Unlike security_scan this is fully PASSIVE (a normal HTTP GET plus a public CT-log lookup, no port scan), so it is safe and lawful to run on domains you do not own. Use http_security or ssl_check for depth on one layer. Read-only; requires no API key; rate-limited. Returns a text report: grade, per-category findings, the out-of-scope list, and a shareable report link.

port_scan
Open Port Scan
Probe a host for a fixed set of common TCP ports (HTTP, HTTPS, SSH, FTP, SMTP, DNS, and common databases) and report which are open, the service name, and the response time. BEHAVIOR: this makes an ACTIVE TCP connection to the target. It is non-intrusive — a connect probe only; it does not authenticate, send exploits, or transfer data — and changes nothing on the target (read-only), but the connection is visible in the target's logs, so only scan hosts you own or are explicitly authorized to test. Use this to confirm which services are exposed. Use ssl_check or http_security instead to assess a specific service's configuration. Requires no API key; rate-limited. Returns a per-port open/closed list with service names.

reverse_dns
Reverse DNS (PTR) Lookup
Resolve the PTR (reverse DNS) record for an IPv4 or IPv6 address and verify forward-confirmed reverse DNS (FCrDNS) by checking that the PTR hostname resolves back to the same IP. Infers the hosting provider from PTR naming patterns. Use this to validate mail-server rDNS or identify a single IP's host. Use asn_lookup instead for network/BGP ownership of the IP. Read-only; requires no API key; rate-limited. Returns the PTR hostname, FCrDNS pass/fail, and a provider guess.

security_scan
Full Domain Security Scan
One-shot comprehensive audit of a domain: runs DNS, SSL, HTTP headers, email auth, port scan, DNS propagation, reverse DNS, and ASN/RDAP checks in parallel, then computes a 0-100 Health Score with an A-F grade and a prioritized action list. Use this as the default starting point for "is this domain healthy/secure?" questions. Call the individual tools (e.g., ssl_check, email_auth) instead when you need depth on one area. BEHAVIOR: this includes an ACTIVE port_scan of the domain's host, so only run it on domains you own or are authorized to test. Read-only otherwise; requires no API key; rate-limited (it makes multiple backend calls). Returns the score, per-area breakdown, top actions, and per-area summaries.

ssl_check
SSL Certificate Check
Inspect a host's served TLS/SSL certificate and connection: expiry date, issuer, SAN list, chain integrity, TLS version, and HSTS, returning an A+ to F grade weighted by certificate validity (40%), TLS version (25%), chain trust (15%), and HSTS (20%). Use this to diagnose certificate or HTTPS-handshake problems for one host. Use http_security instead to audit response security headers, or security_scan for an all-in-one domain report. Read-only: it completes a TLS handshake but sends no application data; requires no API key; rate-limited. Returns a text report: grade, expiry/issuer KPIs, issues, and actions.

subdomain_discovery
Subdomain Discovery
Enumerate the subdomains of a domain from Certificate Transparency logs — fully passive (no packets are sent to the target; CT logs are public records of every TLS certificate ever issued). Flags operational-looking names (dev, staging, admin, vpn, legacy) and wildcard certificates, because forgotten subdomains are a common takeover path. Use this as the first recon step to map a domain's attack surface. Use dns_lookup to check whether a discovered name still resolves, or lookalike_domains for typosquat variants of the domain name itself. Read-only; requires no API key; rate-limited. Returns the subdomain count, risky-name count, wildcard flag, and the hostname list.

subnet_calc
IPv4 Subnet Calculator
Compute IPv4 subnet details from CIDR notation entirely locally — no network call: network and broadcast addresses, usable host range, total usable hosts, subnet mask, and wildcard mask. /31 and /32 are handled per RFC 3021 (point-to-point / single host). Use this for IPv4 address planning. It does not query DNS or contact any host, so it is purely computational. Requires no API key and is NOT rate-limited (computed in-process). Returns the calculated fields as text.

watch_domain
Watch a Domain (daily re-check)
Start (or reuse) a daily DechoNet watch on a domain so that changes are recorded over time — SSL grade/issuer/expiry, DNS records, HTTP security headers, domain registration, and optionally OWASP posture and impersonation exposure. Use this once when the user cares about a domain beyond a one-off check (their own domain, a client, a vendor, a target under investigation). After this, domain_changes answers "what changed since last time?" from real daily snapshots. Not read-only (it creates a watch record) but idempotent: watching an already-watched domain returns the existing watch. No account, no email, no PII — a watch is keyed by domain+tool and its history page is a public unguessable URL you can share with the user. Rate-limited (a few watches per minute).

whois_lookup
WHOIS / RDAP Domain Lookup
Retrieve domain registration data via RDAP (with WHOIS fallback): registrar, creation/expiry/update dates, nameservers, and EPP status flags, highlighting risk states such as clientHold and pendingDelete. Use this for ownership, lifecycle, and expiry questions about a registered domain. Use dns_lookup instead for live DNS records, or reverse_dns/asn_lookup for IP-level ownership. Read-only; requires no API key; rate-limited. Returns registrar, key dates, nameservers, and status flags.
