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 (2)

check_domainread-onlyCheck a domain before your agent trusts a link, a sender or a counterparty: does it exist, where does its mail go, SPF and DMARC policy, nameservers, DNSSEC. Free tier (preview). For registration age, registrar, parking detection and a 0-100 risk score use the paid x402 endpoint /v1/domain.
check_emailread-onlyCheck an email address an agent is about to store, email or trust: syntax, disposable / throwaway provider, role account, free webmail. Free tier (no network). For MX, mail auth, domain age and a verdict (valid | risky | undeliverable) use the paid x402 endpoint /v1/email.

Schemas: list_tools.
