EU supplement prices per 1000 mg of the element, compared within one chemical form.
Scored across 4 tools
Each tool has a clearly distinct role: browsing elements, browsing forms within an element, ranking products within a form, and fetching one product by slug. The relationships between these operations are explicit, so an agent can choose correctly without confusion.
All names use snake_case and are readable, with get_* and list_* following a familiar verb_noun pattern. cheapest_in_form is an understandable exception but does not follow the same verb-first convention as the others.
Four tools is well-scoped for a focused supplement price-comparison server. Each tool supports a distinct step in the browse-and-rank workflow, and none feels redundant.
The surface covers the core lifecycle of discovering elements, finding forms, ranking products, and retrieving product details. Minor gaps exist around free-text product search or broader catalogue listing, but the main workflow is workable.
