Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (3)

check_domainread-onlyCheck a domain only (no local part; anything containing "@" is refused): disposable (the domain or a parent domain is on the disposable-email-domains list), free webmail provider, look-alike (confusable) domain and a typo suggestion. Use this when you do not need the part before the @. Read-only. Same engine, keys and limits as GET /v1/domain/{domain}.
check_emailread-onlyCheck one email address against the disposable-email-domains list (CC0): disposable (domain or a parent domain is listed), role address (info@, admin@ …), free webmail provider, look-alike (confusable) domain, practical syntax, and a one-character typo suggestion for big webmail domains. List-based and offline: no MX/DNS lookup, so a valid format does not mean the mailbox exists. The address is sent in a POST body and not stored or logged. Read-only. Same engine, keys and limits as POST /v1/check.
get_metaread-onlyReturn the service version and build, the disposable-list version, domain and allowlist counts, the last refresh time, the upstream source and licence (CC0), and the current limits. Does not count as a check. Read-only. Same data as GET /v1/meta.

Schemas: list_tools.
