TLD Bench
Domain prices for every TLD at the top registrars: renewals, N-year totals, history, availability.
What it does
TLD Bench is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.
No capability identified yet from its description.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

10 tools offered to AI assistants
compare_tld_prices· Use this when the user asks what an extension costs or where it is cheapest. Returns every registrar's register, renew, transfer and restore prices for one TLD, ranked by the N-year cost of ownership (default 3 years), with each price's soucheapest_registrar· Use this when the user wants the single best place to buy (or transfer) one or more extensions for N years. Ranks by the total cost of ownership, not the first-year promotion; returns the winner with a year-by-year breakdown, three runners-total_cost_of_ownership· Use this when the user compares the long-run cost of several names or extensions, at one registrar or the cheapest. Applies minimum terms and regular renewals; with transfer_after_year it also finds the cheapest registrar to move to later.check_availability· Use this when the user asks whether specific domain names are free. Checks the registry (RDAP, WHOIS for some ccTLDs) after a DNS pre-check, with an honest unknown, and adds the cheapest registrar's price to own each free name. Up to 50 namsearch_name_across_tlds· Use this when the user has a name and wants to know which extensions are free and what each costs to own. Checks one label across up to 50 extensions (or a preset: popular, tech, cheap, country:<cc>) and sorts the free ones by total cost.suggest_names· Use this when the user needs name ideas. Pass `candidates` from your own brainstorm and we check and price them; with only `keywords` we add simple prefixes, suffixes, TLD hacks and combinations. Returns only names that are available or unkget_registrar· Use this when the user asks about a registrar: its country, group, size (gTLD domains under management), how many extensions it sells, and how fresh our prices for it are. Accepts our id, its name or an IANA id.price_history· Use this when the user asks how an extension's prices have moved or whether a rise is coming. Returns each registrar's price periods (changes only) and the registry's announced wholesale changes.list_coupons· Use this when the user asks for promo codes, coupons, deals or first-year discounts. Returns coupon codes as each registrar's own API or promotions page lists them (code, operation, extensions, discount, limits, end date, last seen at the sget_tld· Use this when the user asks what an extension is, who runs it, or whether it fits: type (generic or country code), registry, brand TLD or not, DNSSEC, RDAP and WHOIS servers, minimum term, second levels, registry fees, and its price summary
What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
