ASP.NET Core MCP server built with OAuth 2.1 and security best practices

By PulseAugur Editorial · [1 sources] ·

A developer at Nextoria Information Technology LLC has detailed the process of building a remote Model Context Protocol (MCP) server using ASP.NET Core. The post highlights the necessity of implementing full OAuth 2.1 for client registration, including support for both Dynamic Client Registration (RFC 7591) and Client ID Metadata Documents. Key security measures discussed involve stateless transport, PKCE with S256, short-lived access tokens, and secure storage of secrets. A critical security consideration addressed is the need for a redirect URI allowlist to prevent malicious client registration attacks. AI

IMPACT Provides technical guidance for integrating AI models like Claude and ChatGPT into custom applications via a remote MCP server.
