DotNet Entra ID Proxy FAQs

Question 1

Can I use this proxy with MCP clients other than Claude AI?

Accepted Answer

While the proxy implements the standard MCP OAuth specification and may be compatible with other clients, it has only been explicitly tested and verified with Claude AI. Other MCP clients might use different OAuth flows that don't require this specific proxy.

Question 2

What are the primary benefits of using this proxy?

Accepted Answer

It provides a ready-to-use, secure foundation for MCP servers, simplifies Entra ID integration for complex clients like Claude AI, ensures secure user identity management, and includes a customizable login UI with branding options.

Question 3

What key security features does this proxy provide?

Accepted Answer

The proxy implements Dynamic Client Registration, supports Dual PKCE Flows for enhanced security, and enables token mapping from Entra ID to secure internal JWTs with rich user claims. It's built with production-ready components like CORS and HTTPS.

Question 4

What is the DotNet Entra ID Proxy?

Accepted Answer

It's a .NET-based OAuth 2.1 proxy designed to bridge the authentication gap between Model Context Protocol (MCP) servers and Microsoft Entra ID (Azure AD), specifically enabling secure integration for clients like Claude AI.

Question 5

Why is this proxy necessary for Claude AI and Microsoft Entra ID?

Accepted Answer

Claude AI requires RFC 7591 Dynamic Client Registration, a feature not directly supported by Microsoft Entra ID. This proxy translates these requirements, allowing Claude AI to securely authenticate against your Entra ID tenant.
