Hypr MCP Gateway: Simplifying OAuth2 Authentication for Your MCP Servers
The Hypr MCP team built an MCP Server Gateway, a reverse proxy that simplifies adding OAuth2 authentication to LLM-based workflows. This gateway addresses shortcomings in existing Identity Provider (IdP) software's support for the MCP specification's authorization framework, such as lack of support for Dynamic Client Registration (DCR) and Authorization Server Metadata (ASM). The article details the gateway's implementation, including using Dex as an IdP, handling CORS, and building OAuth2 middleware. It also discusses challenges encountered, like inconsistencies in client handling of dynamic client registration and error responses. The Hypr MCP Gateway offers an easy-to-use, robust solution for securely connecting internal applications to LLM workflows. Check out their open-sourced project on Github.
