Crossmint Checkout MCP Server
Crossmint's Checkout API allows programmatic purchase of physical and virtual goods and services, with programmable money: stablecoins. It enables your AI agent to reliably purchase over 1 billion items, without any cost overhead, nor hassle and unreliability of having to use virtual debit cards and browser use to pay in online forms.
If your agent can obtain an item SKU/identifier, this API can let it buy it.
Capabilities
This MCP server takes an item identifier (from URL to SKUs) and allows you to execute a purchase of it in a single API call.
These purchases are real:
- The item is delivered with expedited shipping
- A receipt is generated
- Sales tax is properly collected
- Returns and refunds are allowed
Available Inventory
- Amazon (US only)
- Prime shipping included
- Shopify (Global)
- Buy anything from any shopify store
Coming soon:
- Flights (~May 2)
- Hotels (Mid May)
- Dining
- Tickets
How are purchases paid
This MCP server requires topping up your server with USDC (stablecoins). A future version will allow payments with credit card, with an automatic conversion into stablecoins in the backend.
How to get USDC
USDC is available in crypto exchanges. In addition, this MCP server integrates Coinbase's onramp, that can return a link where you can top up manually.
Setup
In its current version, this server must be ran locally, due to limitations on MCP security features.
Also, the delivery address for the order is hardcoded during set up.
