## Description

Better-Auth MCP Server provides tools for setting up, migrating to, and maintaining Better-Auth authentication systems in web applications. It offers capabilities for analyzing project structures, configuring Better-Auth implementations, testing authentication flows, and debugging security issues. The server implements the Model Context Protocol to expose tools for project analysis, migration planning from existing auth systems (like auth.js/next-auth), security testing, and real-time monitoring of authentication processes. Configuration requires a Better-Auth project ID and API key, and the server can be deployed using Docker or run directly with Node.js, making it valuable for developers implementing or troubleshooting authentication in their applications.
