Worked on the microsoft/teams.py repository to enhance the reliability and maintainability of the MCP HTTP transport layer. Delivered a focused refactor that unified the application of MCP-recommended timeouts across both authenticated and unauthenticated endpoints, addressing silent timeout issues and improving user experience during tool calls. The approach involved consolidating HTTP client creation using Python and asynchronous programming techniques, simplifying the transport logic by removing conditional branches between different client flows. This backend development effort ensured that all endpoints, regardless of authentication method, now consistently use a 300-second read timeout, resulting in more predictable and robust API integration behavior.
