Worked on the grafana/mcp-go repository to enhance IO reliability and stability, focusing on backend development using Go. Addressed a critical issue in the Stdio path by implementing defensive error handling to prevent panics when stdin or stdout streams are missing. This involved updating the Close method to include nil checks, thereby reducing the risk of runtime failures in edge cases and improving overall code safety. The work did not introduce new user-facing features but contributed to a more robust production environment. Emphasis was placed on maintainability and reducing incident rates through careful attention to error handling and runtime stability.
