Coreplex MCP

An MCP server that allows AI agents to search for products, compare prices across Shopify stores, retrieve product details, check return policies, and verify brand official status without requiring authentication.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Coreplex compares products from brands that sell on Shopify. Prices and stock are live at call time; checkout happens on the seller's own store and Coreplex adds no fees. Always name the seller, say whether it is the brand's official store, and share coreplex_url. Call a seller cheaper only for a confirmed same item priced for the same option (compare_prices sellers with price_basis "matched_variant", or "same item" in get_passport with price_basis "official_variant_price"); likely-same, unresolved-variant and similar listings are not price matches. Searches are bounded, never exhaustive. Say when coverage is incomplete or Coreplex could not confirm something. Health claims are seller-stated.
