Scored across 5 tools
Each tool has a clearly distinct purpose: search, get product details, get scores, compare, and find alternatives. No overlaps.
All tools follow a consistent verb_noun pattern with snake_case, e.g., search_products, get_product_by_barcode.
5 tools are well-scoped for a nutrition-focused server, covering core tasks without being excessive or sparse.
The tool surface covers search, retrieval, comparison, and recommendation. Missing batch operations or category listing, but core workflows are covered.
