update_cart_item
shallowio.kifly/mcp · Verify this server
Requires `checkout:write` scope. Change the quantity of a line item in an open cart, or remove it entirely. Set `quantity` to 0 to remove the item. Get the `item_id` from `get_cart` or the `cart` field in the `add_to_cart` response. Returns the updated cart state. **The per-item quantity ceiling applies here too — call `get_platform_limits` to check the current limit.** Exceeding it returns 400 `QUANTITY_EXCEEDS_LIMIT`.
