Description

This project provides a ready-to-use .NET boilerplate for building secure Model Context Protocol (MCP) servers integrated with Microsoft Entra ID (Azure AD). It bridges the authentication gap between MCP clients like Claude AI and ChatGPT and Entra ID by implementing dynamic client registration and OAuth proxy flows. The server includes customizable login UI, token mapping, user claims extraction, and supports production-ready features such as CORS, HTTPS, and structured logging.
