Worked on the keboola/mcp-server repository to implement selective job execution by configuration row IDs in the MCP Tool. This feature allows targeted execution of jobs for specific configuration rows, rather than running all jobs, optimizing operational efficiency and feedback cycles. The approach involved extending the JobsQueueClient to accept optional configuration row IDs and updating the run_job method to utilize this parameter. Developed comprehensive tests to validate row-level execution and ensure API consistency with the underlying Queue API. The work was carried out using Python and focused on backend development, API design, and robust testing to improve reproducibility and maintainability.
