The official MCP C# SDK now supports OAuth 2.0 authentication and RFC 9728 Protected Resource Metadata, making secure AI integrations simpler for .NET developers.

Tired of agents making wrong assumptions about user input? Visual Studio Code now supports MCP elicitations, where servers can request structured input through the client’s native UI, completely eliminating guesswork and tedium of interpreting LLM input.

Recent experiences with Model Context Protocol development, including conferences, security work, and community updates from Build, MCP Developer Summit, and AI Engineer World’s Fair.

Learn how to implement secure authentication for MCP servers using Microsoft Entra ID with session-based tokens. This improved approach uses confidential clients and JWT session tokens for better security than public client methods.

Learn how to integrate Microsoft Entra ID authentication with Model Context Protocol (MCP) servers. This step-by-step guide explores the challenges and solutions for implementing OAuth-based flows between AI tools and MCP servers, with practical code examples.

To remove the toil of writing authentication code directly, our team at Microsoft has been working on adding a new tool to the developer toolbox - an authentication broker.
