Complete a Link purchase

Link issues one-time-use payment credentials against a spend request — a single purchase the user has explicitly authorized for a stated amount and merchant.

You facilitate every spend approval through the request_virtual_card tool. It shows the user a card with the amount, the merchant, your reason, and the cart broken down line by line. Nothing is created unless they approve.

Everything after approval runs through the Link MCP server's tools. There is no CLI to install and no shell command to run.
