What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

• customcat_list_products

  List the products you set up in CustomCat (a design on one or more catalog items) with variants, SKUs, cost, price, stock flag and design images. Use the variant SKUs when placing an order for these products. GET /product.

• customcat_get_product

  One of your CustomCat products by id (e.g. 22-2580581): variants, SKUs, cost, price, options, designs. GET /product/{product_id}.

• customcat_list_designs

  List the designs uploaded to your CustomCat account: id, name, tags, image URLs, default product and last-updated time. GET /design.

• customcat_list_catalog_categories

  The CustomCat catalog categories (Digisoft, Sublimation) and their subcategories (e.g. T-Shirts, Sweatshirts, Bags), to narrow customcat_list_catalog. GET /catalogcategory.

• customcat_list_catalog

  Browse the full CustomCat catalog of printable blank products (the items you can order with your own artwork). Filter by category and subcategory from customcat_list_catalog_categories. The reply carries the total in `total`. GET /catalog.

• customcat_get_catalog_product

  One catalog product by numeric id with its colors, sizes and SKUs. GET /catalog/{catalog_product_id}.

• customcat_get_catalog_sku

  One catalog SKU with its price and stock status. Use it before ordering: a SKU that is out of stock, discontinued or invalid makes the order fail. GET /catalog/sku/{catalog_sku_id}.

• customcat_list_shipping_methods

  The shipping methods CustomCat offers for a destination country (ids and names). The method name is required when placing an order. GET /shipping.

• customcat_get_shipping_cost

  Calculate the shipping cost of one shipping method for a destination and a list of catalog SKUs with quantities. Read-only quote: it places nothing. POST /shipping/{shipping_id} (shipping_id from customcat_list_shipping_methods).

• customcat_get_order_status

  Status of an order by YOUR order id: order status (Pending, Verified, Shipped), per-item production status, shipments with tracking ids, totals and the ship-to address. Set sandbox=true to look up a sandbox test order. GET /order/status/{order_id}.

• customcat_create_order

  WRITE: place an order for CustomCat to print and ship. This CHARGES the payment method on file in your CustomCat account (product cost + shipping; a front+back print adds $5 per line item) unless sandbox=true, which only validates the order. A real order (sandbox=false) also need

• customcat_cancel_order

  WRITE: cancel (delete) an order by YOUR order id. CustomCat can only cancel an order that has not gone into production; one already printed or shipped is refused. Needs the Write API key. Confirm with the user first. DELETE /order/{order_id}.
