Allowance MCP

Allowance is a payment security layer for AI agents. It lets agents request scoped human approval, receive limited virtual cards, complete checkout, and report receipts without exposing the human's real card.

What agents can do

• Request a spend limit for a specific merchant and reason
• Wait for human approval through Allowance
• Fetch approved contact, shipping, and billing details when checkout requires them
• Issue short-lived virtual cards for approved purchases
• Report purchase success or failure for auditability
• Use remote no-browser checkout where supported
