A3.9/5.0
Scored across 5 tools
Disambiguation4/5
x402_browse and x402_discover both return service lists, but browse is a free full-catalog view while discover is a paid keyword search with ranking and code snippets. Health and attest are related to status but distinct: real-time health check vs signed quality attestation.
Naming Consistency4/5
All tools share a consistent x402_ prefix followed by a single word. Most are imperative verbs (discover, browse, register, attest), while health is a noun, but it clearly maps to a health-check action, so the pattern remains predictable.
Tool Count5/5
Five tools is well-scoped for a discovery-focused server: search, catalog browsing, health checking, registration, and attestation. Each tool has a distinct job and none feels redundant.
Completeness4/5
The core discovery workflow is covered: search, browse, health, register, and signed attestation. The main gaps are managing existing registrations, such as updating or unregistering a service, but agents can still complete primary discovery tasks.
