Over a two-month period, contributed backend features to the harness/mcp-server repository, focusing on API development and integration using Go and gRPC. Delivered a Connector Details Retrieval API that introduced new DTOs and a tool endpoint, enabling detailed connector information to be accessed programmatically for improved debugging and observability. Subsequently, implemented pipeline input sets management tools, defining DTOs and client/server methods to support listing and retrieval of pipeline input sets, which streamlined pipeline configuration workflows. The work emphasized robust API design and backend development, enhancing system transparency and lifecycle management without introducing major bug fixes during the reported timeframe.
