check-domain
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 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"

get-product-details
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"

list-categories
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).

{'type': 'object', 'properties': {}}
list-stores
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.

Limit to the deeply audited stores in one category (e.g., "footwear"); see list-categories. Most browsing is better without it.'}, 'platform': {'type': 'string', 'description': 'Restrict to one platform, e.g. "wix", "shopify", "woocommerce".'}}}
search-all
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. 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

Optional.'}, 'category': {'type': 'string', 'description': 'Optional. Limit the fan-out to the deeply audited stores in one category (e.g., "footwear"); see list-categories. Most queries search better without it.'}, 'maxStores': {'type': 'integer', 'description': 'Maximum number of stores to search (default: 5, max: 10)'}}}
search-catalog
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"

Must be a UCP-enabled Shopify store.'}, 'country': {'type': 'string', 'description': 'ISO country code for localized pricing/inventory (e.g., "US", "GB", "CA"). Optional — defaults to store default.'}}}
search-policies
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"
