onyx_dns_lookup
InactiveTool of onyx-paid-mcp
Resolve a domain to its A/AAAA records, or reverse-resolve an IP to its hostname. Useful for validating a domain exists before scraping, checking if two domains share infrastructure, mapping CDN origins, or doing safety lookups before agents call third-party APIs. Returns IPv4, IPv6, canonical hostname, and resolution time. Powered by stdlib so results are whatever the host's DNS resolver returns — typically 20-100ms. (price: $0.001 USDC, tier: metered)
