The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
check_domain ~226
Check if ONE specific domain (e.g. acme.io) is registrable right now. Use for a single fully-qualified name; to test one word across many extensions, use search_domains instead. Returns an availability verdict, the cheapest registrar and its buy link, the first-year price, and — for taken names — the registration year. Availability is confirmed by RDAP + DNS-over-HTTPS, authoritative for most TLDs; ambiguous names (premium suspects, trademark-blocked names, and zones with no reliable RDAP such as .co/.me) are additionally cross-checked against a third signal (Fastly Domain Research). When no source is authoritative or they disagree, the verdict comes back as uncertain rather than guessed — treat uncertain as 'unknown, NOT available', and note that price may be absent for such names.
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | yes | A single fully-qualified domain including its TLD, e.g. 'acme.io'. URLs and 'www.' prefixes are stripped automatically. Not a bare word — use search_domains to test a word across multiple TLDs. |
No output schema declared.
No examples provided.
compare_registrars ~155
Compare what 6 registrars (Namecheap, Cloudflare, Porkbun, GoDaddy, Spaceship, OVHcloud) charge for a given TLD — first-year registration, renewal, and 3-year total — exposing the renewal traps that cheap first-year promos hide. Use for pricing a TLD you already intend to buy; this does NOT check whether a specific domain is free (use check_domain for that). Returns per-registrar rows with buy links, or a notice if no fresh cached pricing exists for that TLD.
| Name | Type | Req | Description |
|---|---|---|---|
| tld | string | yes | A single TLD WITHOUT the leading dot, e.g. 'com', 'io', 'ai'. A leading dot is stripped if present. |
No output schema declared.
No examples provided.
get_domain_age ~125
Return the registration (creation) year and expiration date of a TAKEN domain, via RDAP. Use to gauge how long a name has been held or when it may expire; it does NOT report availability (use check_domain for that). Returns a 'could not determine' notice for names with no RDAP creation record (some ccTLDs, e.g. .co).
| Name | Type | Req | Description |
|---|---|---|---|
| domain | string | yes | A fully-qualified domain including its TLD, e.g. 'acme.com'. Meaningful only for taken/registered domains; available names have no registration date. |
No output schema declared.
No examples provided.
search_domains ~200
Check ONE name across MANY TLDs in a single call (e.g. 'acme' → com, io, ai …). Use when comparing extensions for the same word; for a single known domain use check_domain instead. Results are grouped AVAILABLE / TAKEN / UNKNOWN, each carrying cheapest price, buy link, and (for taken names) registration year. Names whose availability cannot be confirmed appear under UNKNOWN and must NOT be treated as available (honest 'unverified' state, never a guess).
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | The name WITHOUT any TLD, e.g. 'acme' (not 'acme.com'). This single word is tested against each TLD in the tlds list. |
| tlds | string | – | Optional comma-separated TLDs without dots, e.g. 'com,io,ai'. Omit to use a curated default set of 11 popular TLDs. Whitespace is ignored. |
No output schema declared.
No examples provided.
