Scored across 5 tools
Each tool targets a distinct on-chain data category: wallet profile, token metrics, protocol TVL, gas prices, and health status. There is no overlap or ambiguity between the tool purposes.
All tool names follow a consistent `x402_` prefix followed by a descriptive noun phrase in snake_case. The naming pattern is uniform and predictable across the entire set.
The server offers 5 focused tools covering a reasonable breadth of on-chain data. This is well-scoped for its stated purpose and each tool earns its place.
The core on-chain data endpoints are covered (wallet, token, TVL, gas), plus a health check. Minor gaps exist such as block or transaction details, but the primary domain surface is solid.
