Tools & capabilities
Buywhere MCP tools 13
search_productsSearch the BuyWhere product catalog by keyword. Treat deliver_to as REQUIRED for buyer-facing use (ISO-3166 country of the end user); it takes precedence over country_code/country and prevents all-market scans. Returns product records with title, description, image, price, and merchant information. Covers e-commerce platforms across Singapore, Malaysia, Indonesia, Thailand, Vietnam, and US. Use compact=true for agent-optimized responses with structured_specs, comparison_attributes, and normalized_price_usd fields. BUY-74597 degraded contract: when the catalog query cannot complete inside the user-facing timeout, this tool returns a 200-OK envelope with `meta.status="degraded"`, `meta.emptiness_reason="api_error"` with `meta.degraded_kind="timeout"` (or `"partial_timeout"` / `"auth_failure"`), `meta.confidence="low"`, and `meta.diagnostic.timed_out_stage` naming the failed stage (catalog_search / offer_aggregation / merchant_join). It never returns an unqualified empty result when the cause is timeout, auth failure, upstream exception, or circuit breaker. Agents should branch on `meta.degraded === true` (or `meta.status === "degraded"`) instead of treating empty `data` as no_match.get_productGet a specific product by its ID, including full details and current price.compare_productsCompare multiple products side-by-side. Returns price, brand, rating, and category for each.get_dealsGet discounted products sorted by discount percentage. Returns schema.org/Product entities with schema.org/Offer properties: price, priceCurrency, availability, originalPrice, and discountPercentage. Covers Singapore, Malaysia, Indonesia, Thailand, Vietnam, and US e-commerce. Supports currency, region (sea, us, eu, au) and country (SG, US, VN, MY, ...) filters. BUY-74597 degraded contract: when the discount-index scan cannot complete inside the user-facing timeout, this tool returns a 200-OK envelope with `meta.status="degraded"`, `meta.emptiness_reason="api_error"` with `meta.degraded_kind="timeout"` (or `"partial_timeout"` / `"auth_failure"`), `meta.confidence="low"`, and `meta.diagnostic.timed_out_stage` (typically `offer_aggregation`). It never returns an unqualified empty result when the cause is timeout, auth failure, upstream exception, or circuit breaker. Branch on `meta.degraded === true` or `meta.status === "degraded"`.list_categoriesList top-level product categories available in the BuyWhere catalog.find_best_priceUse this whenever a user asks about prices, wants to find the cheapest option, or asks "what's the best price for X" or "where can I buy X for the lowest price". Returns schema.org/Product entities with schema.org/AggregateOffer (lowPrice, offerCount, priceCurrency) across all merchants. BUY-74597 degraded contract: when the candidates query cannot complete inside the user-facing timeout, this tool returns a 200-OK envelope with `meta.degraded=true`, `meta.status="degraded"`, `meta.emptiness_reason="api_error"` with `meta.degraded_kind="timeout"` (or `"partial_timeout"` / `"auth_failure"`), `meta.confidence="low"`, and `meta.diagnostic.timed_out_stage="catalog_search"`, with `best_price=null` and `alternatives=[]`. It never returns an unqualified empty result when the cause is timeout, auth failure, upstream exception, or circuit breaker.find_similarFind products similar to a given product using vector similarity. Returns up to 10 nearest neighbours by semantic meaning (title+description embedding). Useful for "more like this" recommendations.ingest_productsIngest (upsert) a batch of products into the BuyWhere catalog. Use this to add or update product listings from any merchant/source. Requires a valid API key with ingest permissions. Accepts up to 1000 products per call with source, SKU, title, price, URL, and optional metadata.search_products_v2REQUIRED deliver_to.

Covers e-commerce platforms across Singapore, Malaysia, Indonesia, Thailand, Vietnam, and US. Use compact=true for agent-optimized responses with structured_specs, comparison_attributes, and normalized_price_usd fields.get_product_v2REQUIRED deliver_to.
