}Supplementscanner is a hosted MCP server for supplement price comparison. It gives AI assistants such as Claude, ChatGPT, Cursor and VS Code live prices from supplement web stores across Europe, normalized to a price per kg, per serving or per capsule. It is free and read-only, and it needs no API key or account.
We scan. You save.
A sticker price says little about value. A 2.5 kg tub of whey and a 900 g pouch, or a jar of 60 capsules and one of 240, only become comparable once the price is divided by what the pack holds. Supplementscanner scans supplement stores continuously and does that division for every product, so each category can be ordered by the price you actually pay per unit.
This MCP server gives an assistant the same view. Ask where whey isolate, creatine monohydrate, magnesium bisglycinate or vitamin D3 costs least per unit, and it answers from live prices, with the store, the pack size, the unit price and a link to buy.
All four tools are read-only.
Money comes back as integer cents plus a string formatted for the market's locale. Every response carries last_scraped_at, so an assistant can tell the user how fresh a price is.
In the Netherlands the service is called Supplementenscanner, and in Spain Suplementoscanner.
https://mcp.supplementscanner.eu answers for every market. Without a market argument it answers for the Netherlands; pass market: "be" for Belgian prices, market: "gb" for British ones, and so on. Each country also has an endpoint of its own, which defaults to that country and otherwise works the same way.
Claude.ai and Claude Desktop: open Settings, then Connectors, choose Add custom connector, and paste https://mcp.supplementscanner.eu.

In developer mode, add a connector with the URL https://mcp.supplementscanner.eu and no authentication.

The supplementscanner-mcp npm package is a stdio bridge: it passes every message to the hosted endpoint unchanged and holds no logic of its own. It needs Node.js 18 or later.
It connects to https://mcp.supplementscanner.eu by default. To connect to a country's own endpoint instead, add its market code to args (["-y", "supplementscanner-mcp", "be"]) or set SUPPLEMENTSCANNER_MARKET.
Yes. The hosted server is free to use, with no API key, no account and no sign-up. Connect any MCP client to https://mcp.supplementscanner.eu and call the tools.
Products are compared within their category on one unit: per kg for protein powder, creatine and other powders, per capsule or tablet for capsule products, and per serving where that is how a product is taken. The pack size comes from the store's own listing. A product whose size cannot be read gets no unit price, rather than a guessed one.
The Netherlands, Belgium, France, the United Kingdom, Poland, Denmark, Spain and Austria. Each market is priced in its own currency (euros, pounds, złoty or kroner), and every response states the market it is scoped to. Markets and stores are added over time, and list_categories returns the live store count for each category.
Prices are refreshed continuously, and the products people see most are checked most often. Every response includes last_scraped_at, the time the data was last scanned.
No. find_cheapest orders by price per unit, and search_products by relevance and then price per unit. See Affiliate links.
Yes. The same catalogue is available as a JSON API at https://api.supplementscanner.eu/v1, described by an OpenAPI document.
Buy links are affiliate links: when someone buys through one, the store may pay Supplementscanner a commission. Commission plays no part in the order of results. Every response that shows prices includes an affiliate_disclosure string, and assistants are asked to pass it on.

Find cheapest products
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.
limitmarketcategory_slug必填in_stock_onlySearch products
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.
limitquery必填marketcategory_slugin_stock_onlymax_unit_price_centsList categories
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.
marketGet product details
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.
