TLDix MCP

An official MCP server for TLDix that allows agents to perform domain WHOIS lookups, SSL certificate checks, and DNS lookups without an account. With a free TLDix account, it enables tracking of domain, hosting, and license renewals, managing tracked items, and viewing account limits via tools like lookup_domain, check_ssl_certificate, and add_domain.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

TLDix tracks domain, hosting and licence/service renewals. lookup_domain, check_domain_expiries and check_ssl_certificate work without an account. The other tools read or change the signed-in user's TLDix list. Dates are YYYY-MM-DD; days_until_expiry is negative for items that already expired.
