Connect in one step

Paddock is a remote MCP server. Add this address to your assistant and start asking for cards:

https://api.paddock.so/agent-commerce/mcp

Claude (web, desktop or mobile): Customize › Connectors › Add custom connector › paste the address › No sign-in › Add.

Claude Code:

claude mcp add --transport http paddock-cards https://api.paddock.so/agent-commerce/mcp

Compatible MCP clients can use the same address. The guide has the official steps for each client, says which clients Paddock has tested, and includes a connection check and a plain HTTP recipe.

Optional, to keep Link connected: an assistant that supports sign-in can use https://api.paddock.so/agent-commerce/mcp/connected instead and connect your Stripe Link account once. You still approve each purchase in Link. Tested in Claude Desktop on October 29, 2026; see Keep Link connected.

Try it

Once connected, ask your assistant:

Find me a thank-you card for a coworker. Nothing funny, no words printed on the art.

You get a few matching cards with a description of the art, the price per format and a picture link. Choose one, give the message and the mailing address, and your assistant prepares the order.

Current catalog prices

Live prices per card, postage and applicable tax included. The price depends on where the card is going: US addresses have agent prices, other countries the standard prices. The table shows the price your assistant pays for each destination, format and artwork. Your assistant reads the current price with every search, and the exact total for each card's address is quoted when the order is prepared. If you do not name a format, Paddock selects the flat card in an envelope and says so.

Send one card or up to 500 in one order. Each card keeps its own design, message, recipient, format and mailing date, so a birthday card, three thank-you postcards and a holiday card can go out as one purchase.

Review and pay once

Your assistant gives you a private link. Open it to see each card rendered, the schedule and the full total, then pay by card at a secure checkout page. Your assistant can also show you the finished card in the conversation and change an unpaid draft before you pay. Looking at the previews is optional. Preparing an order never charges you.

Follow your order

Use the same private link, or ask your assistant, to check payment, printing and mailing status. Eligible cards can be cancelled for a refund before the production cutoff. Other cards in the same order keep their schedule.

Can my assistant pay for me?

Yes, through Stripe Link. You approve the exact purchase in Link, then your assistant completes the payment with pay_order and reports the paid order. One live purchase was completed this way in Claude Desktop on October 29, 2026. You can also pay at the secure checkout page. See the Link payment setup.
