Shopify's agent-commerce category filter didn't filter on any of 190 stores
Every Shopify store answers an agent-commerce endpoint whose schema declares a category filter. Sent to 200 live stores with a price-filter control: 186 ignored it, 4 rejected every value, 0 filtered.
One row per Shopify storefront that answered its own agent-commerce endpoint (POST /api/ucp/mcp) on 2 September 2026: 190 of 200 sampled from a corpus of 10,099. Each row records what search_catalog returned with no filter, with the store's own category as a filter, with a foreign category, and with a price ceiling and a price floor as the control.
Method: Each store was asked the same four search_catalog calls through the Model Context Protocol binding the store advertises at /.well-known/ucp. A category filter counts as working only when it removes products outside the category and keeps those inside it; the price filter is the control that shows the same call path can filter.
Columns: store, query, products_no_filter, categories_seen, category_sent, products_impossible_category, products_own_category, products_own_category_bare, products_price_max_1_cent, products_price_min_1000, verdict.
