Implementation Reference
- The core handler function for the 'view_current_cart' tool. It loads locally tracked cart data from JSON file, computes summary statistics (total items, quantities, split by pickup/delivery), and returns the cart contents and summary. Note that it only tracks items added via this MCP server, not the actual Kroger cart.
