Worked on the grafana/mcp-go repository to deliver enhanced _meta field type support for text and blob resources, focusing on flexible metadata handling and robust data modeling. The approach involved updating type definitions in Go, implementing optional _meta parsing, and adding comprehensive tests to ensure backward compatibility for resources without _meta fields. Emphasized backend development best practices by strengthening test coverage and maintaining CI-friendly changes, supporting future refactors and metadata-driven workflows. No major bugs were addressed during this period, as the work centered on reliability, maintainability, and preparing downstream tooling for extended metadata scenarios through careful engineering and thorough testing.
