Why it is in this group
- The name "search_deals" says "search": a word for reading.
Description, as the server wrote it
Search active (not expired) deals on Pechincha.ai, 10 per page by default (`limit` up to 25); with `query` the most relevant come first, without it the newest, unless `sort` says otherwise. Each result has price and old price in BRL, discount %, store, coupon code if any, publication date, the deal page URL and the product photo URL. Content is Brazilian Portuguese, so search in Portuguese: `query` matches whole words (and their start: "celular" finds "celulares") plus meaning ("blusa de frio" finds hoodies), so describe the item in a few words, e.g. "moletom de capuz azul"; with 3+ words one may be missing. Accessories that mention the term also match ("notebook" returns backpacks and cables too), so check titles. For a budget ("até R$ 3.000"), pass `max_price`; for a floor or a range ("entre R$ 100 e R$ 200"), pass `min_price` too. For seasonal events, gift ideas and niches (Black Friday, Dia das Crianças...), pass `theme` from list_themes.

3 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
