## Quality 90/100 (strong)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 93 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 1 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 7 of 7 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 2,209 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 1 of the 7 days needed

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 7, about 2,209 tokens to load them all
- tool set hash: 4ddbb3f99b8608ba0c8438241f43cf9f
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.hardtab/supercheap-shopping.svg)](https://protogrid.dev/servers/io.github.hardtab/supercheap-shopping)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (7)

- `catalog_get_product`: Get product details, offer, attributes, variants, media, and a SuperCheap deep link. If the item is a supplier preview, this may request background supplier-detail hydration and returns its current status; retry while pending until full product details are available before choosing a configuration or adding it to a cart.
- `catalog_get_similar_products`: Find similar products with stable continuation across catalog and supplier sources. Use nextCursor with the same item and market for subsequent pages. A short page is not exhaustion when continuation is present. If status is pending or supplierExpansion is queued, running, or throttled, retry at retryAfter or supplierRetryAt. Supplier previews must be hydrated with catalog_get_product before choosing a configuration or adding to cart. Present only buyer-market offer prices, never supplier costs.
- `catalog_report_product_impressions`: Record only products that were actually presented to the shopper. Searching alone does not mark products as viewed. This idempotent impression signal is used to demote or exclude products in later searches.
- `catalog_search_products`: Search canonical products with category, attribute, price, provider, vendor, sorting, and bounded pagination filters. Attribute pairs are forwarded to supplier discovery as provider Pid/Vid filters when expansion is needed, so keep the exact attributeId/valueId returned by facets. When the shopper requests N products, set limit=N (1–48); leave it unset to use the default of 12 when no count is specified. Set compact=true when limit exceeds 24; compact changes card payload size, not card selection. The product-card UI displays every returned item and supplier preview, up to 24 cards per result. Do not fetch a larger page and then select fewer only in prose: those returned cards still appear in the UI. If the shopper wants only the existing catalog or says not to search suppliers, set expandSuppliers=false so previews are not added. When product-card UI is attached, do not claim product photos are unavailable solely because the text response lacks inline images; refer to the rendered cards. Set freshOnly=true to exclude products already opened or explicitly exposed to this shopper. Use nextCursor for stable exploration pages, or nextOffset when nextCursor is unavailable; keep using the same query and filters. If status is pending, wait until retryAfter and resume with nextCursor as cursor, or nextOffset as offset when no cursor is returned; never restart a pending search from the first page. Supplier discovery automatically runs in the background for missing, weak, or exhausted results unless expandSuppliers=false. A broad result withholds unconfirmed canonical cards and describes only the current page. Continue with nextCursor when present, otherwise nextOffset; zero supplier previews on a page does not mean the search is exhausted. If supplierExpansion is queued, running, or throttled, wait until supplierRetryAt and repeat the same search. Set waitForSupplierResults=true to have the server poll a queued supplier expansion for up to maxWaitMs before returning.
- `category_get_tree`: Return a bounded category subtree. Use rootCategoryId and maxDepth to avoid loading the entire taxonomy.
- `category_search`: Find canonical SuperCheap categories using lexical and semantic matching.
- `market_list`: Find supported SuperCheap country, language, currency, and checkout availability combinations.
