A4.1/5.0
Scored across 5 tools
Disambiguation5/5
Each tool has a distinct role: product discovery (search_products, get_product), cart management (add_to_cart), and payment processing (checkout, confirm_payment). The sequential flow is clear and there is no overlap between tools.
Naming Consistency4/5
Most tools follow a consistent lowercase verb_noun pattern (add_to_cart, confirm_payment, get_product, search_products). 'checkout' deviates slightly as a single verb, but it is still clear and follows the same overall style.
Tool Count5/5
With 5 tools, the server is well-scoped for a simple purchase workflow. Each tool is necessary for the core flow of searching, viewing, adding to cart, and completing a purchase.
Completeness4/5
The purchase lifecycle is covered end-to-end: search, retrieve details, add to cart, checkout, and confirm payment. Minor gaps exist such as no update/remove cart functionality, but these do not block the primary workflow.
