# Supplementscanner

> Supplementscanner continuously scans 48 supplement stores across 2 markets and normalizes every product to a price
> per unit (per kg, per serving, or per capsule), so an agent can name the lowest real price per unit, not
> just the lowest sticker price.

This is the brand's international address. It lists no products itself: each market
has its own site, catalogue and currency, and every response states the market it
is scoped to.

## Markets

- NL: Supplementenscanner, https://supplementenscanner.nl (EUR, nl). MCP: https://mcp.supplementenscanner.nl
- BE: Supplementscanner, https://supplementscanner.be (EUR, nl-BE). MCP: https://mcp.supplementscanner.be

## MCP server (recommended)

One streamable HTTP endpoint (anonymous, read-only) answers for every market:

- https://mcp.supplementscanner.eu

Without a `market` argument it answers for nl. Pass `market` (nl, be) to read
another, or connect to a market's own endpoint above.

Tools: `find_cheapest` (lowest price per unit in a category), `search_products`
(typo-tolerant catalogue search), `list_categories` (discover category slugs),
`get_product` (detail and price history).

## Notes

- Money is integer cents plus a preformatted string in the market's locale.
- Compare products on `unit_price_cents` / `unit_price_display`.
- Each `buy_url` is an affiliate link; relay the `affiliate_disclosure` beside prices.
- Both channels are rate-limited per IP; no key required.
