Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• list-stores open 7h ago

  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 open 7h ago

  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 unknown never probed

  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 unknown never probed

  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 unknown never probed

  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"

  arguments 21 lines copy
• search-all unknown never probed

  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. Rare query words count for more than common ones. If no store's catalogue matches well enough, it searches no one and says "No strong match", naming the words no store carries and the closest weak matches, so you can go to a store you know instead of rewording. 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 unknown never probed

  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 unknown never probed
