Worked on the modelcontextprotocol/typescript-sdk repository to enhance the reliability of Authorization Server metadata discovery. Focused on stabilizing the login and discovery process by addressing a critical bug that previously caused failures across different environments. The solution involved adopting path-based URLs exclusively for metadata retrieval, ensuring consistent and correct behavior regardless of deployment context. This change was implemented using TypeScript and required a strong understanding of API integration and full stack development principles. The update reduced incident risk and improved the robustness of authentication flows, with the technical approach documented and consolidated through a dedicated commit in the project’s codebase.
