Worked on the mondaycom/mcp repository to enhance board activity analytics by introducing targeted filtering capabilities. Developed new item_ids and user_ids filters for the get_board_activity feature, updating the underlying GraphQL queries to support these refined views. Focused on improving usability and reliability, the implementation allows users to analyze activity related to specific items or users, streamlining the debugging process and enabling more focused insights. Comprehensive tests were added, including scenarios with empty filters, to ensure robustness and maintain high test coverage. The work leveraged JavaScript, TypeScript, and API development skills, emphasizing maintainability and reliability in the analytics workflow.
