What it can do

Tool names and descriptions exactly as the server reported them on Nov 12, 2026. The maker wrote them, not us; we show them as plain text.

check_aspa_path
Check an AS_PATH against the published ASPA objects (RPKI attestations of which providers a network authorises), following the verification procedure of draft-ietf-sidrops-aspa-verification. The result is valid, invalid or unknown, with the reason and the first hop that broke the
check_lookalike
Check whether one domain or Web3 name is a visual look-alike (homograph): letters from different scripts mixed in one label, or every non-ASCII letter having a Latin twin, so раураl.com reads as paypal.com. Returns the scripts used and the Latin name it imitates. Use it to screen
check_mail_security
Grade one domain's email authentication and list every check: SPF (single record, the 10 DNS-lookup limit across includes, the all qualifier), DMARC (policy, inheritance from the organizational domain, pct, report addresses), MTA-STS, TLS-RPT, BIMI, DANE and null MX. The level is
check_route
Check one (prefix, origin AS) pair against the public records: RPKI route origin validation (RFC 6811), the routing registries (IRR route objects) and how many RIPE RIS peers see that origin for the prefix. Use it to answer whether an AS is authorised to originate a prefix, why a
get_tld_info
Facts about one top-level domain from local datasets: whether it is delegated in the root zone, its type (country-code or infrastructure when derivable), the registry's RDAP server, root-zone name servers, whether the root zone publishes a DS record (DNSSEC) and which DS algorith
list_data_sources
List the local datasets and feeds behind lookup_target (RIR delegations, IANA, Public Suffix List, cloud / CDN ranges, Tor and Private Relay, reputation lists, GeoLite2) with state, record count, generation date and a stale flag. Use it to judge how current a reputation, RIR, clo
lookup_many
Look up up to 10 domains, IPs, CIDRs, ASNs or Web3 names in one call and get one short line per target (type, registrar and expiry, nameservers, network owner, origin AS, cloud, reputation, Web3 status) plus the same facts as structured fields and a details_url for each. Use it t
lookup_target
Look up one domain, IP address, CIDR block, ASN (AS15169), EVM address (0x…) or Web3 name (ENS .eth, Unstoppable, SPACE ID .bnb, Handshake hns:) and get a compact fact sheet. Domains: registrar, dates, status, nameservers, DNS records, overall mail-security grade, third-party ser

Common questions

Is DC5 WHOIS safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2026.11.13) reached the registry 2 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

What can I use instead?
