Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

domain

check_domain_availability

Use this when the user wants to know if a domain name is available or taken, or asks "can I get <name>". Accepts a full domain ("acme.io") for one verdict, or a bare name ("acme") to check it across popular TLDs (com, io, ai, co, app, dev, net, org, xyz) or a custom TLD list. Checks live DNS, registry RDAP/WHOIS and a registrar; never claims "available" without registrar confirmation. Returns a verdict per domain, buy links for names that may be free, and a tld.expert URL to cite.

explain

explain_tld

Use this when the user asks what a domain extension is, what it means, who runs it, who can register it, or whether it fits their project ("is .ai good for a startup", "what is .io", "does .web exist"). Returns tld.expert’s editorial verdict, pros and cons, registry, registration restrictions, the use cases it ranks for, and a typical price. Also answers for well-known non-existent TLDs like .eth or .web.

suggest

suggest_tld_alternatives

Use this when the domain the user wants is taken (or they ask for other options for a name). Given a full domain like "acme.com", proposes other endings (acme.io), added words (getacme.com), domain hacks and related words, checks every candidate live, and returns only the ones that are not taken. Slower than a single check (up to ~30 live lookups).

tld

get_tld_prices

Use this when the user asks what a domain extension costs, where it is cheapest, or what it renews at. Returns dated first-year, renewal and transfer prices per registrar (Porkbun, Dynadot, Cloudflare, Namecheap where tracked), the cheapest direct buy, the wholesale floor, and a renewal-trap flag when the renewal is 2x+ the intro price. Prices are the TLD standard price, not premium names. Also answers "what does it cost over 5 years": true_cost gives each registrar's 1/3/5/10-year cost, the cheapest path per horizon (stay, or register at one and transfer after year one for gTLDs) and recent renewal price changes, each with source URL and checked date.

tld.expert — questions

Answers built from our own checks of this server.

What can tld.expert do?

It exposes 4 tools, read directly from the server on our last check. Among them: check_domain_availability, explain_tld, get_tld_prices, suggest_tld_alternatives. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is tld.expert working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 73 ms. The bar chart above shows every period we have measured.

The registry lists tld.expert as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect tld.expert?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does tld.expert need an API key?

No. tld.expert completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
