I think I found a bug in the storefront MCP server. It appears that the search_shop_catalog tool is ignoring the price filter. I had this reported by a customer and replicated with my test shopify store.
Below is the request and response. You will notice that in the response 4/5 of the products’s min price range is above the max requested.
