Worked on the Azure/azure-mcp repository to address a reliability issue in MCP Client Annotation discovery. Focused on backend development and API refactoring using C#, the developer corrected the search logic for McpServerToolAttribute by moving it from the GetCommand method to ExecuteAsync. This adjustment ensured that tool annotations are properly discovered and propagated to MCP clients, reducing the risk of missing annotations and improving integration reliability. The work included updating the CHANGELOG.md for traceability and maintaining clear documentation. Over the month, the primary contribution was a targeted bug fix, demonstrating attention to detail and a methodical approach to backend problem-solving.
