Worked on enhancing the reliability of real-time data streams in the modelcontextprotocol/typescript-sdk repository, focusing on backend development and network protocols using TypeScript. Addressed a critical issue affecting Server-Sent Events (SSE) under server-side compression by ensuring that intermediate proxies and caches do not transform SSE connections. This was achieved by adding the 'no-transform' directive to the Cache-Control header in both client and server SSE transport configurations, directly improving connection stability and reducing the risk of dropped events in production. The work emphasized API integration and maintainability, aligning the fix with existing caching and transport strategies for robust real-time streaming.
