Server tool list (14)
Raw names from tools/list. Only developers need these.
| search_ebay | Search live eBay listings by keyword and/or category across 8 sites (US, GB, DE, AU, CA, FR, IT, ES), built on eBay's official Browse API. Returns id, title, price, condition, seller feedback, shipping, image, categories, and URL per listing. Returns an honest `credentials_required` error until the upstream deployment has EBAY_CLIENT_ID/EBAY_CLIENT_SECRET provisioned. |
| get_ebay_item | Get one eBay item's full detail — description, brand/MPN/GTIN, color, item specifics, images, return terms, availability, item end date — by REST item id or legacy numeric id. Returns an honest `credentials_required` error until the upstream deployment has eBay app credentials provisioned. |
| get_ebay_items | Bulk-fetch full item detail for up to 20 eBay items in a single call, given comma-separated item ids. Returns an honest `credentials_required` error until the upstream deployment has eBay app credentials provisioned. |
| search_ebay_sold | Sold/completed-item price comps. This needs eBay's Marketplace Insights API, which is a limited-release approval separate from the base Browse API. Until that is enabled on the upstream deployment, this always returns a 501 `not_enabled` gate rather than a fabricated result — that is expected, honest behavior, not a bug. |
| search_shopify_products | List any public Shopify store's product catalog straight from that store's own /products.json — no keys, no auth, works today. Returns title, vendor, product type, tags, price range, variants, images, and URL per product. Pass a bare storefront domain, e.g. `allbirds.com`. |
| get_shopify_product | Get one product from a public Shopify store by its handle (slug), from that store's own /products.json — keyless, live now. |
| get_shopify_collections | List a public Shopify store's collections (id, handle, title, product count, image) — keyless, live now. |
| search_shopify | Filter a public Shopify store's catalog by keyword across title, vendor, product type, and tags — keyless, live now. |
| search_bestbuy | Search Best Buy's US product catalog by keyword and/or category, built on Best Buy's official Products API. Returns sku, title, sale/regular price, rating, manufacturer/model, image, online/in-store availability, and UPC per product. Errors honestly until this engine is fully live upstream: currently returns `not_found` (route not yet redeployed on the production commerce-api), then `credentials_required` once deployed without BESTBUY_API_KEY provisioned. |
| get_bestbuy_product | Get one Best Buy product by SKU, full detail. Errors honestly until this engine is fully live upstream: currently returns `not_found` (route not yet redeployed on the production commerce-api), then `credentials_required` once deployed without BESTBUY_API_KEY provisioned. |
| search_etsy | Search Etsy's site-wide active listings by keyword, built on Etsy's official Open API v3 (app-only, no OAuth). Returns title, description, price, quantity, tags/materials, favorites, images, and shop per listing. Errors honestly until this engine is fully live upstream: currently returns `not_found` (route not yet redeployed on the production commerce-api), then `credentials_required` once deployed without ETSY_KEYSTRING/ETSY_SHARED_SECRET provisioned. |
| get_etsy_listing | Get one Etsy listing by id, full detail — the only endpoint where Etsy's API populates `views` (search and shop-listings results always have `views: null`, since Etsy doesn't carry that field there). Errors honestly until this engine is fully live upstream: currently returns `not_found` (route not yet redeployed on the production commerce-api), then `credentials_required` once deployed without ETSY_KEYSTRING/ETSY_SHARED_SECRET provisioned. |
| get_etsy_shop | Get one Etsy shop by shop_id or shop_name — name, listing counts, favorites, total sold, aggregate review count/average. Errors honestly until this engine is fully live upstream: currently returns `not_found` (route not yet redeployed on the production commerce-api), then `credentials_required` once deployed without ETSY_KEYSTRING/ETSY_SHARED_SECRET provisioned. |
| get_etsy_shop_listings | List one Etsy shop's active listings, optionally keyword-filtered within the shop. Errors honestly until this engine is fully live upstream: currently returns `not_found` (route not yet redeployed on the production commerce-api), then `credentials_required` once deployed without ETSY_KEYSTRING/ETSY_SHARED_SECRET provisioned. |
