Qué puede hacer

Nombres y descripciones de las herramientas tal como los informó el servidor el 6 nov 2026. Los escribió el creador, no nosotros; los mostramos como texto sin formato.

  • 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

  • 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 (4

  • 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/C

  • 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/receivin

  • 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; i

  • 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 sing

  • 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 identi

  • 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

  • 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

  • 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 certificat

  • 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 vi

  • 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

  • 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

  • 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 addres

  • 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 do

  • owasp_check Parece una instrucción para la IA

    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 Failu

  • 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

  • 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

  • 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

  • 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_hi

  • 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

  • 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, HT

  • 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 (pas

  • check_before_action Parece una instrucción para la IA

    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

  • 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 sa

  • 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 F

  • 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 Korea

  • 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), a

  • 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

  • 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 report

  • 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 se

  • 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, impersona

  • 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

DechoNet MCP Server

[dechonet.com](https://dechonet.com) · Remote MCP (no install) · Phishing link check · Free web tools · HTTP API · Detection benchmark · Status

Domain security reconnaissance for AI agents via the Model Context Protocol.

33 tools. No API key needed for non-commercial use. Phishing/smishing link checks, exposed admin page checks (admin screens, test servers, dev tools left open), DNS, SSL/TLS, post-quantum TLS readiness, HTTP security headers, email authentication, port scan, DNS propagation, reverse DNS, ASN/BGP, RDAP/WHOIS, subdomain discovery (CT logs), lookalike/typosquat detection, OWASP-mapped observable checks, brand-impersonation exposure, go-live readiness, MCP server checks before you connect one, domain change history — what changed since the last check — infrastructure history and pivots (past nameservers/IPs/issuers, and other domains seen on the same rare infrastructure), a daily watch you can set from the agent, and crypto checks — a wallet address's chain and OFAC sanctions listing, whether a site is an exchange's official address, and a check before an agent signs or sends.

Every result comes back interpreted, not just as raw JSON: a status, the key numbers, each issue with severity and confidence, and the concrete action to take. That is what an agent needs to tell a human what to do next.

Part of [DechoNet](https://dechonet.com). Every tool here is also a free web tool at [dechonet.com](https://dechonet.com) — no sign-up — backed by error-fix guides. This package brings the same checks to AI agents.

Zero-install: remote endpoint

No npx, no install. Point any MCP client that speaks Streamable HTTP at:

https://dechonet.com/mcp
ClientHow to connect
Claude Codeclaude mcp add --transport http dechonet https://dechonet.com/mcp
Claude app / DesktopListed in the Claude connectors directory: Customize → Connectors, search DechoNet → Connect. Or + Add → Add custom connector with the URL (Free plan: one custom connector)

Any stdio-only clientnpm package — see Quick Start below

Step-by-step for each client: dechonet.com/mcp. The remote endpoint also serves 3 curated prompts (audit_domain, monitor_setup, investigate_changes) and 2 reference resources.

Quick Start (stdio, Claude Desktop)

Add to your claude_desktop_config.json:

{

"mcpServers": { "dechonet": { "command": "npx", "args": ["-y", "dechonet-mcp"] } } }

Config file location:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json

Restart Claude Desktop; DechoNet shows up in the chat input's tools menu. (Claude Desktop can also skip the install and add https://dechonet.com/mcp as a custom connector — see the table above.)

Install

# Via npx (no install needed)

npx dechonet-mcp

Or install globally

npm install -g dechonet-mcp

Command line

The same checks work from a terminal or a CI step — no MCP client needed:

npx dechonet-mcp ssl example.com

npx dechonet-mcp email example.com --json npx dechonet-mcp scan example.com --fail-on bad # exit 2 when the overall grade is D or F

Checks: dns, ssl, http, email, port, propagation, rdns, asn, whois, subdomains, lookalike, scan, owasp, golive, pqc, mcp, phishing, exposure, changes, history, impersonation, ip, subnet (or any tool name below). --json prints the structured result, --raw keeps the raw data, --port sets the TLS port. Exit codes: 0 done, 1 the lookup failed, 2 the result reached --fail-on (bad or warn). With no arguments the package runs as the MCP server.

Available Tools

ToolDescription
phishing_link_checkIs this link a scam? — paste a text message or URL; follows shorteners, checks domain age, Korean brand impersonation, APK downloads, phishing feeds
exposure_mapAdmin pages open to the internet? — subdomains from CT, each opened once: admin screens, staging, dev tools, VPN logins, default pages, directory listings (counts; per-host detail for the verified owner on the web report)
security_scanComprehensive scan — 9 checks in parallel, 0-100 Health Score, A-F grade
dns_lookupDNS records + DNSSEC + SPF/DMARC validation
ssl_checkSSL/TLS certificate, chain, expiry, HSTS, CT history, A-F grade
http_securityHTTP redirect trace + 10 security headers audit, A-F grade
email_authSPF, DMARC, DKIM, BIMI, MTA-STS, DANE + blacklist check
port_scanOpen TCP ports with service identification
dns_propagationDNS propagation across 6 public resolvers
reverse_dnsPTR record + FCrDNS verification
asn_lookupASN/BGP network identification + abuse contact
whois_lookupRDAP/WHOIS domain registration data
subdomain_discoveryPassive subdomain enumeration from CT logs, operational-name flags (dev/staging/admin), wildcard detection
lookalike_domainsTyposquat variants that are actually registered — homoglyph, affix (brand-login), TLD swap, keyboard slips — with the domain's own defensive registrations separated out
owasp_checkOWASP-mapped checks that can be observed passively (headers, TLS, exposed files), honest about what is out of scope
impersonation_exposureBrand impersonation exposure grade: third-party lookalikes + exposed operational subdomains + wildcard certs
golive_checkGo-live readiness — DNS, propagation, SSL, HTTP, registration in one READY / CAUTION / NOT READY verdict
domain_historyPast nameservers, A/AAAA, MX, certificate issuer, registrar (and an IP's ASN/PTR) with first and last seen — from DechoNet's own observations, not passive DNS
infrastructure_pivotOther domains DechoNet saw with the same nameserver, IP, MX, issuer or registrar. Needs a free API key (DECHONET_API_KEY); shared infrastructure returns a count only
domain_changesWhat changed since the last check — status, grade, issuer, DNS, issues. Works from lookup history even without a watch
pqc_readinessPost-quantum TLS readiness: hybrid X25519MLKEM768 key exchange, whether the origin server or a CDN edge provides it, certificate signature algorithms. External indicator, not a full PQC audit
mcp_server_checkBefore you connect a remote MCP server: authentication and OAuth metadata, tools that act (commands, files, messages, payments, secrets), agent-steering text in tool descriptions, CORS/Origin, HTTPS. Initialize and tools/list only — no tool is called
watch_domainRegister a domain for daily re-checks (SSL, DNS, HTTP, RDAP) so domain_changes accumulates a timeline. Writes a watch; idempotent
set_expectationsState what a domain should show from outside (a header present, DMARC enforcing, an issue gone, a grade, certificate days, DNS records, HTTPS answering), check it now with fresh reads and every day after. Each result comes with a signed observation receipt; with an API key, a set that stops holding is reported in your account's daily mail
check_before_actionBefore logging in, paying, downloading or submitting: whether the page impersonates a brand, how new the domain is, whether it was flagged before, and — when the caller reports the page structure as host names — whether the card fields sit with a known payment provider. Answers danger / suspicious / unreachable / official / no_signals, with what was not checked; never 'safe'
report_pageReport a page (phishing, fake payment window, hidden instructions for AI agents, malicious download, or a verdict that looks wrong), an MCP server whose tool descriptions steer agents, or a network anomaly (the certificate or addresses you saw differ). Only the host and kind are kept; a report changes no verdict by itself — DechoNet checks the page itself, independent reports first
verify_expectationsCheck a stored set (by id) or a one-off list from outside now — after a change, to see whether it is visible yet
wallet_address_checkCrypto wallet address: chain from the format (EVM, TRON, Bitcoin, Solana), checksum, the US Treasury OFAC SDN sanctions list (read daily) and how many pages DechoNet judged dangerous showed it. Not listed is not 'clean'; the address is not stored
crypto_exchange_checkIs a domain the official address of a Korean or global exchange, wallet or dApp — compared only with addresses the companies publish themselves; a domain that only uses the name gets its age, first certificate and a phishing check
crypto_check_before_signBefore an agent signs or sends: the destination address, the page that asked and the wallet request (unlimited approvals, Permit signatures, setApprovalForAll) judged together — danger / suspicious / no_signals, with what was not checked
ip_infoPublic IP, ISP, ASN, proxy detection
email_header_analysisEmail delivery route tracing + auth results
subnet_calcCIDR subnet calculator (offline)

Every tool response ends with a link to the full interactive report on dechonet.com for the human behind the agent.

Example Prompts

Once connected, try asking Claude:

  • "Audit the security posture of example.com"
  • "Is the SSL certificate for mysite.com about to expire?"
  • "Which subdomains of example.com are exposed in CT logs?"
  • "Are there registered lookalike domains of mybrand.com?"
  • "How exposed is mybrand.com to impersonation?"
  • "Is example.com ready to go live?"
  • "What changed on example.com since the last check?"
  • "Analyze these email headers: [paste headers]"
  • "What's the ASN for 8.8.8.8?"

Local SSE Transport

For a self-hosted HTTP/SSE bridge (the hosted remote endpoint above is usually simpler):

npm run start:sse

Server runs on http://localhost:3100

SSE endpoint: http://localhost:3100/sse

Development

npm install

npm run build # TypeScript → build/ npm run dev # Run with tsx (stdio) npm run start:sse # Run SSE server
