# XposedOrNot Breach Intelligence (MCP server)

> XposedOrNot Breach Intelligence is an MCP server that adds messaging tools to AI assistants such as Claude Code, Cursor and VS Code. Real-time data-breach lookup and analytics for emails and domains from XposedOrNot. It has 96 GitHub stars, is released under the MIT license and runs as a remote server at https://api.xposedornot.com/mcp.

Data breaches happen constantly, and most people only find out long after their email and passwords are already circulating. I built XposedOrNot so you don't have to wonder. Check an email or domain and know right away whether it's turned up in a known breach.
