Worked on the modelcontextprotocol/registry repository to enhance backend stability and user experience by addressing error handling for client cancellations in the ListServers API. Focused on mapping Go’s context.Canceled to HTTP 499, the update ensured that graceful client disconnects no longer generated error-level logs, reducing unnecessary log noise and clarifying cancellation reporting. This approach improved observability and simplified incident triage for operators without altering the API’s public contract. The work demonstrated skills in Go, API development, and backend error handling, and was merged following maintainer review, with further refinements documented for future follow-up in the project’s issue tracker.
