A4.1/5.0

Scored 2026-09-17 00:15 across 9 tools

Disambiguation3/5

Most tools have distinct targets (docs, pricing, endpoints, instruments, plans), but several pairs are easy to confuse: get_pricing_info vs get_product_catalog, get_market_data_endpoint vs get_workflow_endpoint, and list_instruments vs search_pairs all cover overlapping catalog/endpoint/pricing territory. The verbose descriptions help, but an agent would still need to read carefully to avoid selecting the wrong one.

Naming Consistency4/5

Names generally follow a lowercase snake_case verb_noun pattern (get_market_data_endpoint, list_instruments, recommend_account_plan), so the set is predictable. The exceptions are the generic single-word verbs fetch and search, which lack the noun object used elsewhere.

Tool Count5/5

With 9 tools, the server is well-scoped for a discovery/API-planning assistant; each tool has a defined job and none add sheer bulk. The number is comfortably in the ideal range and matches the breadth of the domain.

Completeness4/5

For its stated purpose of helping agents search Blocksize docs, understand pricing/plans, discover instruments, and build x402 endpoint templates, the surface is quite complete. The only notable gap is that it intentionally stops short of fetching live data or executing payments, so users must leave the server to do the actual market-data call.
