The boundary is the design: it returns products and merchant links and never takes a payment, so an agent can shop without your product inheriting a payments problem.
A hosted, closed-source MCP server for product discovery across independent stores on the open merchant web. One call takes a natural-language shopping intent and returns ranked results — best picks, alternatives, bundles, caveats, prices and merchant links. It stops at discovery: no checkout, no payment, no orders.
- A natural-language shopping intent turned into ranked product results
- Best picks, alternatives, bundles and caveats, with prices and links back to the merchant
- A completed discovery fetched again by result_id
- Feedback reported against a result you were given
- The stores it covers, listed
- A purchase_boundary block on every response, restating that the purchase happens on the merchant's own site
