• 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_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/{or
• 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
• 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

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
