Pop Pay

Overview

Pop Pay is a Model Context Protocol (MCP) server: Runtime security for AI agent commerce. CLI + MCP server blocks hallucinated purchases. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.

It runs locally: the npm package pop-pay speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.5.7, published under the MIT license, with source at 100xPercent/pop-pay on GitHub.

You'll find Pop Pay in the AI & Agents category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
