Pop Pay

Pop Pay is an MCP server and CLI tool providing a secure runtime layer for AI agent-driven commerce, focused on preventing hallucinated or unauthorized purchases. It enables AI assistants and agents (e.g., Claude, Cursor, Windsurf, OpenClaw) to safely complete commerce actions, such as filling payment forms, requesting virtual cards, and handling API-based payments (via x402 protocol), by strictly controlling credential flow. With browser/CDP-based credential injection, encrypted local vault, vendor/category whitelisting, and transaction guardrails (keyword or LLM-based), Pop Pay is ideal for developers, organizations, and anyone integrating AI agents with payment/checkout flows needing robust runtime payment security and hallucination mitigation.
