Authoryze MCP server

What it does

Authoryze is a remote MCP server that lets AI agents request purchases through a human-approval workflow and single-use virtual cards. It is aimed at developers who want to give agents a payment method with defined merchant, category, and spending-limit controls, built on Visa Intelligent Commerce and Mastercard Agent Pay for US-issued cards.

• An agent requests a purchase from a specific merchant and amount, triggering an approval flow before any card details are issued.
• After a purchase is approved, the agent retrieves a single-use virtual card number, expiry, and CVV to complete the transaction.
• A developer checks how much an agent has spent against configured daily, weekly, monthly, or total limits using the spending summary tool.

Tools this server exposes

check_status	Looks up the current status of a previously submitted purchase request without exposing any card details.
get_spending_summary	Returns how much has been spent against configured limits (daily, weekly, monthly, and total) for the agent and account.
retrieve_card	Returns the card number, expiry, and security code for an approved purchase; can only be called once per approval.

Before you enable it

An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
