Just a week ago I was talking about an approach to authenticating into MCP servers with Entra ID. While the approach was OK as a prototype, it had some interesting aspects to it that might or might not work depending on the context. But what if we could improve this a bit?| Hi, I'm Den 👋 on Den Delimarsky
Not too long ago, Anthropic put forward a draft specification that outlines how authentication and authorization works in the context of MCP. It's pretty vanilla in terms of what you'd expect from an OAuth-based implementation, but it gets a bit trickier if we try and integrate Microsoft Entra ID into it.| den.dev
