Available tools 2

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

certificate

check_certificate

Connects to a domain on port 443 and reports its TLS certificate: whether it is trusted and matches the name, the issuer, the expiry date and days left, the lifetime, the chain and the TLS version, what each of its server addresses serves (up to 4 IPv4 and 4 IPv6), and, for certificates from Let’s Encrypt, Google Trust Services, ZeroSSL or Sectigo, the renewal window the CA suggests (ACME Renewal Information).

domain

check_domain_expiry

Looks up a domain registration over RDAP at the registry for its TLD: when it expires, the registrar, the statuses (flagging a hold, redemption, pending delete or pending transfer) and the nameservers. Subdomains are looked up by their registered domain (www.example.co.uk becomes example.co.uk).

How do I connect Boring Utils Expiry Watch?

Does Boring Utils Expiry Watch need an API key?

No. Boring Utils Expiry Watch completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
