Tasks these servers can do
Will this Shopify product CSV import cleanly?
Call csv_import_preflight on Catalog QA Desk (https://catalogqa.openkrill.app/mcp). Blocking problems and warnings by row. The CSV is read in memory and not stored. Send a product export, not an order export.
Install steps: ChatGPT, Claude, Cursor, VS Code, Pi.
What products and prices does allbirds.com publish right now?
Call check_store_prices on Store Price Tracker (https://stores.openkrill.app/mcp). A reading of the public /products.json feed, after robots.txt, identified as StorePriceTracker. A store you ask about can be added to a daily snapshot list of public product data.

What they will not do
Candidate tariff codes, when you need them, come from Tariff & HS Code Duty Finder and are not a customs ruling. Catalog QA does not upload a feed or promise that Merchant Center will accept a row.
