About
Claude (or any MCP client) runs a full checkout on acp-sandbox through a hosted MCP server and pays with a real PayPal sandbox payment that a human approves. No real money, no signup. A live dashboard shows every request and response the agent sends, so you can see exactly what it did.
Under the hood it is a free mock merchant implementing the Agentic Commerce Protocol (ACP, from OpenAI and Stripe): the checkout_sessions lifecycle (create, update, complete, cancel). Already used by a payment-infrastructure founder building AI-agent payment governance, who said it "did exactly what I needed."
