    How to connect Name.ai MCP Server to Claude

    2. Go to Settings → Connectors.
    3. Click Add custom connector.

    5. In a chat, click + → Connectors and switch the new connector on.

    Server tool list (4)

    Raw names from tools/list. Only developers need these.

    search_domainCheck whether a domain is available and, for the same label, whether its common alternate TLDs are too (e.g. querying "acme.com" also returns "acme.ai", "acme.io", ...). Backed by POST /api/domain/search — public, no auth required. Buy-now (aftermarket/marketplace) prices are hidden unless you're authenticated (see AUTH.md at name.ai for how to get a token) — an unauthenticated call only sees new-registration pricing for a domain that's simply unregistered. Pass a valid OAuth access token as this call's Authorization header and it's forwarded automatically. Args: domain: A domain name to check, e.g. "example.ai". include_alternates: When true (default), also return sibling TLDs for the same label. When false, only the exact domain is returned.
    whois_lookupLook up WHOIS/RDAP registration details for a domain: registrar, registrant, creation/expiration dates, nameservers. Backed by POST /api/tools/whois — public, no auth required, but rate limited by name.ai to 10 lookups per day per caller IP. Since every MCP call shares this server's egress IP, that quota is pooled across all of this MCP server's callers, not per end user. Args: domain: A domain name to look up, e.g. "example.com".
    tld_registration_priceGet the current USD price for a domain-lifecycle operation on a TLD (new registration, transfer-in, renewal, or restore from redemption). Backed by GET /api/pricing/tld — public, no auth required. This is name.ai's own registration pricing, not an aftermarket/marketplace price, so it is never gated by sign-in status. Args: tld: The TLD without a leading dot, e.g. "ai" or "com". operation: One of "register", "transfer", "renew", "restore".
    tld_requirementsGet registration requirements for a TLD: allowed registration period range, whether an organization is required, allowed registrant countries, nameserver rules, and similar registry policy. Backed by GET /api/tlds/{tld}/metadata — public, no auth required. Args: tld: The TLD without a leading dot, e.g. "ai" or "io".
