Check whether any domain supports the Universal Commerce Protocol, find verified UCP storefronts by category or intent, and read their catalogs and policies. Every store is re-checked daily and linked to its public conformance record. Read-only: this server never creates carts or checkouts — you transact with the merchant directly.

list-stores	List verified UCP storefronts across every platform, best-evidenced first. Use when the user wants to browse stores — e.g., "what stores can I shop at?" or "show me Wix stores". To find stores that sell something, prefer search-all. Each store carries what we have actually observed about it, not what it claims: - `transactable` — declares checkout and we have read its catalogue - `catalogued` — we have read its catalogue - `resolvable` — its endpoint resolves, we have not probed it yet - `declared` — a valid manifest, nothing observed beyond it Filter by `platform` (shopify, wix, woocommerce, bigcommerce, shopware…). `category` narrows to the smaller set of deeply audited stores (see list-categories), so leave it out unless the user asks for a category. Developer previews and staging hosts are not listed.
list-categories	List store categories with store counts. Categories exist only for the deeply audited subset of verified stores, so this is a way to browse, not the whole index: list-stores and search-all cover every verified storefront. Sorted by number of stores (most first).
check-domain	Check if a domain supports Universal Commerce Protocol (UCP). Returns the UCP status, manifest version, capabilities, response latency, and AI bot access policies (GPTBot, ClaudeBot, Google-Extended, etc.). If the store's edge rate-limits the live attempt, the result says so and reports the last OBSERVED state and when it was observed — an unobserved attempt is never presented as a verdict about the store. The domain is automatically normalized (removes protocol, www, paths). Examples: "shopify.com", "https://www.example.com/path" → "example.com" A negative result is information, not permission. It reports what UCP Checker has observed — it does not say a store cannot be used, and it is not a reason to stop. If a store matters to your task, try discover-store or connect to it directly regardless of what this returns.
discover-store	Discover available shopping tools on a UCP-enabled store. Connects to the store's MCP endpoint and lists all available tools (search, cart, shipping, etc.). Use this to understand what a store supports before shopping. Example: domain: "allbirds.com"
search-catalog	Search for products on any UCP-enabled Shopify store. Searches the store's live product catalog via UCP/MCP and returns matching products with titles, prices, variants, and images. Examples: - domain: "allbirds.com", query: "tree topper" - domain: "gymshark.com", query: "hoodie"
search-all	Search for products across verified UCP stores at once. Fans the query out, concurrently, to the stores whose observed catalogue best matches it, and returns results grouped by store with each store's UCP score and evidence. If no store's catalogue matches, it searches the best-evidenced stores instead and says so. Slow or failing stores are skipped. `category` narrows the fan-out to the smaller set of deeply audited stores; leave it out for most queries. Example: query: "mattress topper", maxStores: 5
search-policies	Search store policies on any UCP-enabled Shopify store. Query return policies, shipping policies, refund policies, privacy policies, terms of service, or any other store policy. Returns the matching policy text. Use this when a user asks about a store's policies before or after purchase — e.g., "what is the return policy?", "do they offer free shipping?", "refund window?" Example: domain: "allbirds.com", query: "return policy"
get-product-details	Get full product details including variant IDs from a UCP-enabled store. Use after search-catalog to see a product's full declared detail, including its variants. Pass the Product ID from search results to get all variants with their IDs. Example: domain: "allbirds.com", productId: "gid://shopify/Product/123456"
