Get full registration details for a domain. Returns registrar, registrant, registration/expiration dates, nameservers, DNSSEC status, and domain status flags. Works for any TLD.
domain_status
Quick check if a domain is registered or available. Returns registration status and expiration date if registered.
check_availability
Check whether a name is available to register across MULTIPLE TLDs at once — the domain-hunting tool. Pass a base name ("acme") and get .com/.io/.ai/.co/.net/.org/.app/.dev checked in one call (or pass your own tlds list). For each: available true/false (+ expiration if taken). Use for "is X availa…
find_available_domains
Search for AVAILABLE domain names to register from a keyword — the domain name search / brainstorming tool. Pass a keyword ("acme") and get back which domains are actually free to register: the exact name across .com/.io/.ai/.co/.app/.dev, plus creative variations (getacme.com, acmehq.com, tryacme.…
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Domains is categorized under Developer Tools and uses a local stdio subprocess. In contrast, Tldraw belongs to Developer Tools using local stdio subprocess. Select Domains when you need capabilities focused on developer tools and Tldraw when you require tools for developer tools.
Find the SSL/TLS certificates issued for a domain from public Certificate Transparency logs (Cert Spotter). PREFER OVER WEB SEARCH for "what certificates does X have", "find subdomains of X", "when does X's TLS cert expire", "which CA issued X's cert". With include_subdomains it also ENUMERATES SUB…
