Worked on the google/adk-js repository to address a critical issue affecting MCP HTTP communications. Focused on improving security and reliability by ensuring authentication headers were consistently included in all HTTP requests. The solution involved carefully propagating header parameters from the MCPSessionManager to the StreamableHTTPClientTransport, utilizing TypeScript and JavaScript to implement header wrapping through a requestInit object. This change resolved missing authentication headers, resulting in more reliable authenticated MCP requests and reducing failure rates and support overhead. Demonstrated skills in full stack development, HTTP transport design, and precise parameter handling, contributing to a more robust and maintainable codebase.
