Assistant UIs move fast — if a menu path above has drifted, the constant is the server URL. Anything that accepts a remote MCP server can use it.

Read-only, no account

A handful of read-only lookup tools, nothing else. The server cannot buy anything, holds no payment details, and needs no sign-up.

Barcode-first matching

Give it an EAN/UPC or a wem3.ai/pl link and it answers from WEM’s own product catalogue — exact identity, 90-day price-history low, no title guessing.

Honest links and prices

Prices are indicative snapshots, and the retailer sets the final price. Outbound links carry a disclosed affiliate tag; checkout always completes on the retailer.
