A4.1/5.0
Scored across 2 tools
Disambiguation5/5
check_domain and check_email target clearly different inputs and use cases. The domain tool handles DNS/mail policy while the email tool handles address syntax and provider classification, so an agent can select reliably.
Naming Consistency5/5
Both tools use a consistent snake_case verb_noun pattern: check_domain and check_email. There are no mixed conventions or vague names.
Tool Count3/5
Two tools is thin for a domain/email verification server, though the scope is intentionally narrow. The descriptions reference paid endpoints that are not exposed as tools, which makes the surface feel incomplete.
Completeness3/5
The free-tier checks are covered, but key operations explicitly mentioned in the descriptions (domain age, registrar, risk score, MX, mail auth, verdict) are only available via paid endpoints not present as tools. This creates notable gaps for agents needing full verification workflows.
Available Tools
2 toolscheck_domainCheck a domain (DNS + email auth)ARead-onlyIdempotentInspect
Check 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.
Inputs: domain (required).
check_emailCheck an email address (syntax + disposable)ARead-onlyIdempotentInspect
Check 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.
Inputs: email (required).
