Lowvyn tracks prices across Amazon.ca, Walmart.ca, Best Buy.ca, and Canadian Tire. Search for products, compare prices, verify whether sales are genuine, and see price trends over time to make smarter shopping decisions.

Example request: "Is this laptop actually on sale, or has it been cheaper before?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Lowvyn to help me. It is a free service with an MCP server at https://api.lowvyn.com/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- find_cheaper: Given a product (by Lowvyn ID or retailer URL), return the same physical product on other Canadian retailers with their current prices and savings. Uses verified UPC matches. Use this when a user wants to know 'can I get this cheaper somewhere else?'.
- get_categories: List the product categories Lowvyn covers, with item counts. Useful for narrowing search_products calls.
- get_price_history: Return the daily price history for a product as (date, price) pairs, up to N days. Use this to verify whether a 'sale' is genuine or whether the price has been higher in the past, or to show a price trend in an answer to the user.
- get_product: Look up a product by Lowvyn ID OR retailer URL (amazon.ca / walmart.ca / bestbuy.ca / canadiantire.ca). Returns title, current price (CAD), Lowvyn Score (0-100), Deal Verdict, and price summary (current / all-time low / all-time high).
- get_retailers: List the Canadian retailers Lowvyn currently tracks, with item counts and last-update timestamps.
- intent_search: Search the Canadian catalogue by a natural-language description of a NEED rather than keywords. Give it what the shopper actually wants (e.g. 'a quiet gaming laptop under $1500', 'a reliable stroller for travel') and it returns the best-matching products with their current price 
- search_products: Search the Canadian product catalogue. Filter by category slug, max price (CAD), and retailer. Returns up to 20 matching products with current price and Lowvyn Score. Use this when a user is exploring what is available in a category rather than asking about a specific product. Ea
- verify_deal: Given a product (by Lowvyn ID, retailer URL, or a lowvyn.com product URL from another tool's result) and an optional claimed price, return whether the deal is genuine. Compares against Lowvyn's price history and returns a verdict ('real_deal', 'modest_deal', 'average', 'bad_time'
