domain-check

Each tool has a clearly distinct purpose: one checks domains, one lists paid services, one explains the partner program, and one registers a referral code. There is no overlap or ambiguity between them.

Three of four tools follow the verb_noun pattern (check_domain, list_services, register_referral), but partner_program is a noun_noun name without an action verb. This is a minor deviation that does not cause confusion.

Four tools is well-scoped for the server's purpose: one core domain-checking tool plus three supporting tools for its referral monetization model. Each tool earns its place without redundancy or bloat.

The core domain-check workflow is fully covered, and the referral flow includes registration, catalog, and program details. A minor gap is the lack of a tool to track referral earnings or history, but this is not essential for the primary domain-check function.
