pop-pay MCP

A runtime security layer for AI agent commerce that prevents hallucinated purchases. It acts as a CLI and MCP server that injects card credentials directly into the browser DOM via CDP, ensuring they never enter the agent's context window, thereby protecting user wallets from unauthorized transactions.
