What it can do
| Tool | What it says it does |
|---|---|
asn_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). For an IPv4 address it also reports whether the address is on the Tor Project exit list, as… |
check_before_action | Check the page an agent is about to log in, pay, download from or submit to: whether the address impersonates a brand, how new the domain is, whether DechoNet or a licensed feed has already flagged it, and — opened from Seoul (and Tokyo for Japan-targeted pages) as a phone — what the page turns… |
crypto_check_before_sign | Before an agent signs or sends from a crypto wallet: send the destination address (to), the page that asked (url) and/or the wallet request it is about to approve (request: the EIP-1193 method and params). The address is checked for its chain and checksum, the US Treasury OFAC sanctions list, the… |
crypto_exchange_check | Check whether a domain or link is the official address of a crypto exchange, wallet or dApp — Korean exchanges (Upbit, Bithumb, Coinone, GOPAX, DigitalX/Korbit) and major global exchanges, wallets and dApps — compared with the addresses the companies publish themselves (the Korean exchanges'… |
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… |
dns_propagation | 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… |
domain_changes | 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… |
domain_history | Show how a domain's (or IPv4 address's) infrastructure has changed over time from DechoNet's stored observations: nameservers, A/AAAA, MX, CNAME, certificate issuer, registrar, RDAP nameservers and status, and for an IP its ASN and PTR — each value with when it was first and last seen. Use this… |
email_auth | 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… |
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… |
exposure_map | Map what an organisation exposes to the internet beyond its home page: subdomains from Certificate Transparency logs (plus hosts DechoNet has already observed), each opened once from outside and sorted into developer/ops tools, directory listings, admin screens, VPN/remote-access logins, staging… |
golive_check | 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… |
http_security | 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 on the six core headers (CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy; COOP/CORP/COEP are reported… |
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… |
infrastructure_pivot | Find other domains DechoNet has seen with the same infrastructure value — a nameserver, IP address, MX host, certificate issuer or registrar — with first and last seen, to map related infrastructure (e.g. other phishing domains on the same rare nameserver). Use it after domain_history or… |
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… |
lookalike_domains | 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… |
mcp_server_check | Check a remote MCP server from outside before connecting it to an agent: whether it requires authentication (and publishes OAuth protected-resource metadata, RFC 9728), which of its tools act on the world (run commands, write or delete files, send messages, make payments, read secrets), whether… |
owasp_check | Assess a domain's OWASP posture from EXTERNAL OBSERVATION only: the OWASP Secure Headers Project plus the externally observable OWASP Top 10:2025 subset — A04 Cryptographic Failures (TLS/cert), A02 Security Misconfiguration (header/info leaks), and A03 Software Supply Chain Failures (outdated… |
phishing_link_check | Check the links in a suspicious text message (smishing) or e-mail before anyone taps them. Paste the whole message or a single URL: every link is extracted, followed through URL shorteners to its real destination, and judged on observable signals — domain age from RDAP, impersonation of Korean… |
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… |
pqc_readiness | Check whether a website's public TLS endpoint is ready for post-quantum cryptography: does it complete a TLS 1.3 handshake that offers only the hybrid X25519MLKEM768 key exchange (ML-KEM), and does the organisation's own server provide it or a CDN edge in front of it. Also reports what the… |
report_page | Report a page to DechoNet: phishing or brand impersonation, a fake payment window (card fields where a payment provider should be), hidden instructions aimed at AI agents, a malicious download, a DechoNet verdict that looks wrong (false_positive) or a danger it missed (missed), an MCP server whose… |
reverse_dns | 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… |
security_scan | One-shot comprehensive audit of a domain, scored 0-100 with an A+ to F grade and a prioritized action list. Five scored areas: the web connection (TLS certificate and HTTP security headers, measured on www when only www has an address), mail spoofing defence (SPF/DKIM/DMARC; a domain that uses no… |
set_expectations | Record what a domain should show from outside and check it now — HSTS or another header present, DMARC enforcing, an issue key no longer reported, an HTTP or TLS grade at or above a level, a certificate with enough days left, a DNS record present, absent or containing a value, HTTPS answering… |
ssl_check | Inspect a host's served TLS/SSL certificate and connection: expiry date, issuer, SAN list, chain integrity, revocation (OCSP, then CRL; unknown when neither answers — not graded unless revoked), TLS version, and HSTS, returning an A+ to F grade weighted by certificate validity (40%), TLS version… |
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… |
subnet_calc | 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… |
verify_expectations | Check expectations from outside now, with fresh reads: either a stored set by id (from set_expectations — its state is updated and an anonymous set is kept another 30 days), or a domain plus a list of checks once, storing nothing. Same checks and outcomes as set_expectations (pass / fail /… |
wallet_address_check | Check one crypto wallet address: which chain it belongs to (EVM, TRON, Bitcoin, Solana — from the format alone), whether its checksum is valid (EIP-55, Base58Check, bech32/bech32m), whether it is on the US Treasury OFAC SDN sanctions list (read daily) or among the addresses the FBI published in an… |
watch_domain | 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… |
whois_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… |
