Developed an API enhancement for the microsoft/azure-devops-mcp repository, focusing on optimizing the WIT query workflow through backend and API development using TypeScript. The work introduced a responseType parameter to the wit_get_query_results_by_id endpoint, allowing clients to select between full result sets or just work item IDs. This approach reduced data transfer and mitigated LLM context overflow for large queries, while maintaining backward compatibility and a streamlined API surface. The implementation included targeted testing for high-volume scenarios and ensured seamless integration with existing contracts, demonstrating careful attention to scalability, extensibility, and the needs of downstream tooling and clients.
