Coreplex searches products sold on Shopify stores, shows which sellers are official brand retailers, compares prices across sellers, and filters health products by certifications like USP and NSF. Checkout happens directly on each seller's Shopify store with no added fees.

Example request: "Find the cheapest place to buy an Owala water bottle from an official store."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Coreplex to help me. It is a free service with an MCP server at https://coreplex.ai/api/apps/6a9567482e969b1ab43e0c49/functions/coreplexMcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- search_products: Find products from Shopify brands; results name the seller and flag official stores. Example: {"query":"Owala FreeSip 24oz","limit":5}
- get_product: One listing: price per option, stock, seller, official-store flag, policy links. Example: {"product_url":"https://owalalife.com/products/freesip"}
- get_return_policy: Seller's return terms (window, condition, opened items, return shipping), each with the policy's exact sentence. Example: {"product_url":"https://owalalife.com/products/freesip"}
- compare_prices: Other sellers of the exact same item (catalog ID or barcode), priced for one variant; similar listings kept apart. Pass variant_id (from get_product) or a ?variant= URL for multi-option products. Example: {"product_url":"https://owalalife.com/products/freesip","variant_id":"4321"
- get_passport: Brand's own listing, then other matching stores found in a catalog search, marked same, likely same or not, with evidence. Example: {"product_url":"https://owalalife.com/products/freesip"}
- list_brands: Brands with a confirmed official Shopify store, optionally by category. Example: {"category":"beauty"}
