Description as the publisher wrote it.
| Tool | What it does |
|---|---|
compare_offers | Exact multi-retailer offers for one product from WEM's own catalogue, cheapest first, with a 90-day price-history low. Identity is resolved by barcode or catalogue slug — no text matching — so every offer IS the product, and the lookup spen Inputs: gtin, slug |
compare_products | Compare 2-5 products side by side. Returns a structured comparison of price, rating, shipping, and key features. Use when the user is deciding between options. Inputs: products |

Uses AI embeddings for semantic understanding — handles vague requests like "comfortable shoes for standing all day" or "gift for a 10 year old who likes science". Falls back to keywo Inputs: description, category, min_price, max_price, limit |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://wem3.ai/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
