🔒 Minimal Entra ID-authenticated MCP Server

Minimal server showing how to implement Entra ID authentication with MCP and HTTP+SSE transport. Unlike the previous server implementation, this relies on a confidential client living inside the MCP server, and then using "session mapping" to make sure that the client gets a session assignment through, what looks like, a JWT token (since we can't use cookies).

Run server

npm install
npm run build
npm run start

Testing

You will need to use MCP Inspector or a tool that supports HTTP+SSE transport for MCP servers and authentication.
