Scored across 1 tool
With only one tool there is no possibility of misselection, and its scope (a pre-payment readiness check) is stated unambiguously in the name and description. An agent can immediately tell this is the sole entry point for the domain.
The single name check_x402_payment_readiness follows a clear snake_case verb_noun pattern that reads naturally and matches the domain vocabulary. There are no competing conventions to create inconsistency.
A single tool is on the thin side for a server surface, even if the underlying job is narrowly defined. It earns its place, but there is little room for the agent to compose operations or inspect sub-parts of the check.
The tool covers the core readiness lifecycle: requirements, network, wallet balance, and budget, returning an actionable PAY/BLOCKED verdict with reason codes. Minor gaps exist, such as no batch check across multiple resources or a helper to enumerate supported networks/schemes.
