### Tool changes

- 2026-11-06 `search_products` changed (description)
  - before: Search every site's catalogue at once for a product, brand or kind of product (typos are corrected per site). Returns products with their site, page URL, manufacturer list price and a summary of current shop offers in the locale's market (shops, buyable, lowest total incl. known shipping). Use compare_prices for the shops and their links.
  - after: Search every site's catalogue at once for a product, brand or kind of product (typos are corrected per site). Returns products with their site, page URL, manufacturer list price and a summary of current shop offers in the locale's market (shops, buyable, lowest total incl. known shipping). Name one or a few `sites` for more of their matches (they share `limit`). Use compare_prices for the shops and their links.

## Tools (5)

- `best_deals`: The largest real price drops right now in the locale's market across the sites: a shop's price against its own lowest price of the 30 days before (never a shop's own "was" price), with the site, product page and shop link.
- `compare_prices`: Shop prices of one product version side by side in the locale's market on the site that lists it (cheapest total first, out of stock last; price, shipping, stock, when checked and the shop link), plus the same version's best price in that site's other markets.
- `find_by_code`: Exact identity lookup on every site: a GTIN/EAN barcode, a manufacturer item number or a LEGO set number. Returns each site's matching product with its current shop offers in the locale's market (cheapest total first, each with its link) and the best price overall. Never a guess: no match means no site lists that exact product.
- `list_sites`: The independent price-comparison sites this server searches (furniture and lighting, tools, toys, LEGO, board games, games, baby, pets, perfume, books, smart home and more): key, name, what each covers, its markets and languages, its home page and its own MCP server for deeper questions (categories, brands, guides, toplists).
- `search_products`: Search every site's catalogue at once for a product, brand or kind of product (typos are corrected per site). Returns products with their site, page URL, manufacturer list price and a summary of current shop offers in the locale's market (shops, buyable, lowest total incl. known shipping). Name one or a few `sites` for more of their matches (they share `limit`). Use compare_prices for the shops and their links.
