onyx_email_validate
InactiveTool of onyx-paid-mcp
Validate an email address: RFC-5322 syntax check, domain DNS resolution (does the domain exist?), and disposable-provider detection (Mailinator, 10minutemail, GuerrillaMail, etc.). Returns a single confidence verdict plus the underlying signals so agents can decide whether to send. Use before mailing list signups, password-reset flows, or sales-lead capture to filter out trash addresses cheaply. ~30-80ms typical. (price: $0.002 USDC, tier: metered)
