Web3 DNS (CNSLookup)

check_name (registration status only) vs resolve_name (full profile + addresses) vs reverse_lookup (address to name) are distinguished clearly by their descriptions. get_payment_address overlaps conceptually with the payments section of resolve_name, but the description explicitly frames it as a pre-payment, single-network shortcut, which is enough to prevent most misselection.

All five tools follow a consistent snake_case verb_noun pattern: check_name, get_payment_address, list_networks, resolve_name, reverse_lookup. No mixed conventions or stray casing.

Five tools is well-scoped for a read-only name lookup service, and each one maps to a distinct query an agent would actually perform. No filler or redundant tools.

The lookup lifecycle is covered: registration check, forward resolution, reverse resolution, per-network payment addresses, and supported networks. Gaps are minor (no batch lookup or list-names-by-owner), and registration/mutation operations appear out of scope for this server.
