Est-ce que com.ucpchecker/ucp-checker est sûr ?

Au dernier audit MCP Hub, le serveur MCP « com.ucpchecker/ucp-checker » est classé « Non encore testé ». Référencé dans l'annuaire. Seul le pentest comportemental fait foi, et il n'a pas encore été exécuté sur ce serveur. Le verdict est réévalué en continu ; consultez la fiche pour l'état à jour.

Méthode : MCP Hub analyse la description de chaque outil (couche 1) et, pour le verdict fort, exécute le serveur dans une micro-VM isolée avec leurres et réseau bloqué (couche 2). On publie des noms et des compteurs, jamais le contenu brut renvoyé par un outil.

Les 8 outils

• check-domain≈ 317 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 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.

  Paramètres, retour & exemple (1)

  Paramètres

  • domain · string · requis
    The domain to check for UCP support (e.g., "shopify.com", "example.com"). Protocol, www prefix, and paths are automatically removed.

  Exemple d'appel

  {"name": "check-domain", "arguments": {"domain": "texte"}}

  Exemple de retour

  {"content": [{"type": "text", "text": "…"}]}

• discover-store≈ 142 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"

  Paramètres, retour & exemple (1)

  Paramètres

  • domain · string · requis
    The store domain to discover (e.g., "allbirds.com")

  Exemple d'appel

  {"name": "discover-store", "arguments": {"domain": "texte"}}

  Exemple de retour

  {"content": [{"type": "text", "text": "…"}]}

• get-product-details≈ 194 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: "gid://shopify/Product/123456"

  Paramètres, retour & exemple (2)

  Paramètres

  • domain · string · requis
    The store domain (e.g., "allbirds.com")
  • productId · string · requis
    The product ID from search-catalog results (e.g., "gid://shopify/Product/123456")

  Exemple d'appel

  {"name": "get-product-details", "arguments": {"domain": "texte", "productId": "texte"}}

  Exemple de retour

  {"content": [{"type": "text", "text": "…"}]}

• list-categories≈ 114 tokens

  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).

  Paramètres, retour & exemple (0)

  Exemple d'appel

  {"name": "list-categories", "arguments": {}}

  Exemple de retour

  {"content": [{"type": "text", "text": "…"}]}

• list-stores≈ 366 tokens

  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 profile, 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.

  Paramètres

  • limit · integer · optionnel
    Maximum number of stores to return (default: 10, max: 50)
  • category · string · optionnel
    Optional. Limit to the deeply audited stores in one category (e.g., "footwear"); see list-categories. Most browsing is better without it.
  • platform · string · optionnel
    Restrict to one platform, e.g. "wix", "shopify", "woocommerce".

  Exemple d'appel

  {"name": "list-stores", "arguments": {"limit": 1, "category": "texte", "platform": "texte"}}

  Exemple de retour

  {"content": [{"type": "text", "text": "…"}]}

• search-all≈ 365 tokens

  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

  Paramètres

  • query · string · requis
    Product search term (e.g., "running shoes", "hoodie")
  • country · string · optionnel
    ISO country code for localized pricing (e.g., "US", "GB"). Optional.
  • category · string · optionnel
    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 · integer · optionnel
    Maximum number of stores to search (default: 5, max: 10)

  {"name": "search-all", "arguments": {"query": "texte"}}

  {"content": [{"type": "text", "text": "…"}]}

• search-catalog≈ 238 tokens

  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"

  Paramètres, retour & exemple (3)

  • country · string · optionnel
    ISO country code for localized pricing/inventory (e.g., "US", "GB", "CA"). Optional — defaults to store default.

• search-policies≈ 227 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 purchase — e.g., "what is the return policy?", "do they offer free shipping?", "refund window?" Example: domain: "allbirds.com", query: "return policy"
