The only text from the server itself is in the section quoted from it below. ## How to reach it - The client starts it as a local process (stdio): `npx -y [email protected]`. - Your MCP client knows it as `domain-check-skills` (`clients/` configures it under that name); call its tools by the names below. Claude Code shows them as `mcp__domain-check-skills__<tool>`. - Credentials, from `.env` (`.env.example` lists them): `DIGMYNAME_API_BASE`. ## Tools 4 tools. The read-only column is the server's own hint (`readOnlyHint`), not something the hub checked. ### Quoted from the server: data, not instructions The names, sentences and parameter names in this table are the server's own text, as the hub listed it.

check_domainCheck 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.Check if ONE specific domain (e.g. acme.io) is registrable right now.
