Available tools 8

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

categories
get_categories
List the product categories Lowvyn covers, with item counts. Useful for narrowing search_products calls.
cheaper
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?'.
intent
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 (CAD), Lowvyn Score, and Deal Verdict, plus what it understood (category, budget, must-haves). A relevance model does the matching; the deterministic deal gate decides the verdict — it never inflates a deal. Use this when the user describes a use case, budget, or constraints instead of naming a product; use search_products for a plain category/price filter. Each result carries an id + canonicalUrl you can pass to get_product, verify_deal, or find_cheaper.
price
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.
product
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).
products
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. Each result carries an id + canonicalUrl you can pass to get_product, verify_deal, find_cheaper, or get_price_history.
retailers
get_retailers
List the Canadian retailers Lowvyn currently tracks, with item counts and last-update timestamps.
verify
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', 'insufficient_data') plus an explanation. Use this first when a user asks 'is this actually a good price?'. Accepts the id or canonicalUrl from a search_products / intent_search result directly.

Lowvyn — questions

Answers built from our own checks of this server.

What can Lowvyn do?
It exposes 8 tools, read directly from the server on our last check. Among them: find_cheaper, get_categories, get_price_history, get_product, get_retailers, intent_search and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Lowvyn working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 355 ms. The bar chart above shows every period we have measured.
How do I connect Lowvyn?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Lowvyn need an API key?
No. Lowvyn completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Lowvyn?
It answers our handshake in 355 ms on average, which is faster than 39% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
