A4.4/5.0

Scored 2026-10-03 15:35 across 4 tools

Disambiguation5/5

Each tool targets a clearly distinct purpose: discovery (list_categories), category-based price comparison (find_cheapest), catalog text search (search_products), and single-item detail (get_product). Descriptions explicitly disambiguate the one potential overlap, telling users to prefer find_cheapest over search_products when the category is known.

Naming Consistency5/5

All four tools follow a consistent verb_noun snake_case pattern (find_cheapest, get_product, list_categories, search_products). No deviations or mixed conventions.

Tool Count4/5

Four tools is a tight, focused set that covers discovery, search, comparison, and detail for a read-only scanner. It sits at the lower end of the well-scoped 3-15 range, so it is reasonable but somewhat lean.

Completeness4/5

The read-only comparison lifecycle is well covered: category discovery, cheapest-per-unit lookup, typo-tolerant search, and full product detail with price history and bulk tiers. Minor gaps exist (e.g. listing all products in a category or browsing price history across items), but core workflows are fully served.

Available Tools

4 tools

find_cheapestFind cheapest products

Read-onlyIdempotent

Inspect

Find the cheapest supplements by normalized price-per-unit within a category (and all its subcategories). This is the primary tool for "what is the cheapest X?" questions. Use list_categories first to pick a valid category_slug.

ParametersJSON Schema

Name	Required	Description
`limit`	No	Maximum number of products to return (1-50).
`market`	No	Optional country market to query: nl, be. Defaults to nl, the market this endpoint answers for. Any other value is rejected.
`category_slug`	Yes	The category to search within, e.g. "whey-protein" or "creatine". Products in every subcategory are included, so a parent slug like "protein-powder" works too. Get valid slugs from list_categories.
`in_stock_only`	No	When true, only return products currently in stock.

get_productGet product details

Read-onlyIdempotent

Inspect

Get full detail for one product by its id: price, normalized unit price, size, bulk/staffel tiers, buy link, and recent price history. Use the id returned by find_cheapest or search_products.

ParametersJSON Schema

Name	Required	Description	Default
`market`	No	Optional country market to query: nl, be. Defaults to nl, the market this endpoint answers for. Any other value is rejected.
`product_id`	Yes	The numeric product id, as returned in the `id` field by find_cheapest or search_products.

list_categoriesList categories

Read-onlyIdempotent

Inspect

List the supplement categories that currently hold priced products, each with a live product count, store count, lowest normalized unit price, and its comparison basis (per_kg / per_serving / per_capsule). Use this to discover a valid category_slug for find_cheapest.

ParametersJSON Schema

Name	Required	Description	Default
`market`	No	Optional country market to query: nl, be. Defaults to nl, the market this endpoint answers for. Any other value is rejected.

search_productsSearch products

Read-onlyIdempotent

Inspect

Search the whole supplement catalog by product name or brand. Typo-tolerant (e.g. "kreatine", "theanin" still match). Results are ordered by relevance, then cheapest normalized price-per-unit. Use find_cheapest instead when you already know the category.

ParametersJSON Schema

Name	Required	Description
`limit`	No	Maximum number of products to return (1-50).
`query`	Yes	The product name or brand to search for, e.g. "whey isolaat" or "magnesium bisglycinaat".
`market`	No	Optional country market to query: nl, be. Defaults to nl, the market this endpoint answers for. Any other value is rejected.
`category_slug`	No	Optional: restrict results to this category and all of its subcategories, e.g. "protein-powder". Must be a slug from list_categories; an unknown slug is rejected.
`in_stock_only`	No	When true, only return products currently in stock.
`max_unit_price_cents`	No	Optional: only return products whose normalized unit price is at or below this many cents.
