Commerce Bridge is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

search_ebaySearch live eBay listings by keyword and/or category across 8 sites (US, GB, DE, AU, CA, FR, IT, ES), built on eBay's official Browse API. Returns id, title, price, condition, seller feedback, shipping, image, categories, and URL per listing. Returns an honest `credentials_requirget_ebay_itemGet one eBay item's full detail — description, brand/MPN/GTIN, color, item specifics, images, return terms, availability, item end date — by REST item id or legacy numeric id. Returns an honest `credentials_required` error until the upstream deployment has eBay app credentials prget_ebay_itemsBulk-fetch full item detail for up to 20 eBay items in a single call, given comma-separated item ids. Returns an honest `credentials_required` error until the upstream deployment has eBay app credentials provisioned.search_ebay_soldSold/completed-item price comps. This needs eBay's Marketplace Insights API, which is a limited-release approval separate from the base Browse API. Until that is enabled on the upstream deployment, this always returns a 501 `not_enabled` gate rather than a fabricated result — thasearch_shopify_productsList any public Shopify store's product catalog straight from that store's own /products.json — no keys, no auth, works today. Returns title, vendor, product type, tags, price range, variants, images, and URL per product. Pass a bare storefront domain, e.g. `allbirds.com`.get_shopify_productGet one product from a public Shopify store by its handle (slug), from that store's own /products.json — keyless, live now.get_shopify_collectionsList a public Shopify store's collections (id, handle, title, product count, image) — keyless, live now.search_shopifyFilter a public Shopify store's catalog by keyword across title, vendor, product type, and tags — keyless, live now.search_bestbuySearch Best Buy's US product catalog by keyword and/or category, built on Best Buy's official Products API. Returns sku, title, sale/regular price, rating, manufacturer/model, image, online/in-store availability, and UPC per product. Errors honestly until this engine is fully livget_bestbuy_productGet one Best Buy product by SKU, full detail. Errors honestly until this engine is fully live upstream: currently returns `not_found` (route not yet redeployed on the production commerce-api), then `credentials_required` once deployed without BESTBUY_API_KEY provisioned.search_etsySearch Etsy's site-wide active listings by keyword, built on Etsy's official Open API v3 (app-only, no OAuth). Returns title, description, price, quantity, tags/materials, favorites, images, and shop per listing. Errors honestly until this engine is fully live upstream: currentlyget_etsy_listingGet one Etsy listing by id, full detail — the only endpoint where Etsy's API populates `views` (search and shop-listings results always have `views: null`, since Etsy doesn't carry that field there). Errors honestly until this engine is fully live upstream: currently returns `notget_etsy_shopGet one Etsy shop by shop_id or shop_name — name, listing counts, favorites, total sold, aggregate review count/average. Errors honestly until this engine is fully live upstream: currently returns `not_found` (route not yet redeployed on the production commerce-api), then `credenget_etsy_shop_listingsList one Etsy shop's active listings, optionally keyword-filtered within the shop.
