During May 2025, Andres Otarola focused on backend reliability for the MichaelCade/mcp-go repository, addressing a key issue related to API-forward compatibility. He resolved a deprecation in the test server’s HTTP context handling by replacing the outdated WithSSEContextFunc with WithHTTPContextFunc, ensuring alignment with the intended API usage and preventing future runtime errors. Working primarily in Go, Andres applied his skills in API development and testing to implement a concise, targeted code change that minimized disruption while maintaining stability. This work improved the maintainability of the codebase and reduced the risk of breakages as the HTTP context evolved.
