Tools

check-domain ~341 tokens
Check if a domain supports Universal Commerce Protocol (UCP). Returns the UCP status, protocol 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
discover-store ~140 tokens
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"
get-product-details ~196 tokens
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:

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: "ho
search-policies ~235 tokens
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 pur
