Thinh Tran enhanced HTTP transport reliability in the modelcontextprotocol/inspector repository by implementing robust handling for 401 Unauthorized responses from the StreamableHTTP transport. Using TypeScript and front end development skills, Thinh introduced logic that detects unauthorized responses and clarifies error semantics, improving client resilience in authenticated flows. The work focused on refining the client’s error handling path, ensuring that unauthorized access is managed gracefully and paving the way for future retry strategies. The changes were delivered as a focused, auditable commit, demonstrating depth in understanding HTTP protocols and client-server interactions while addressing a specific reliability concern within the codebase.
