Worked on deployment stability for the keboola/mcp-server repository, focusing on improving the Sync Actions flow by ensuring accurate image tagging during deployments. Addressed a bug where the runtime.image_tag from saved configurations was not consistently applied, which previously led to unintended use of default tags. The solution involved preserving the root runtime block within configData, allowing runtime fields such as image_tag to be honored by default without introducing new parameters. This backend improvement, implemented using Python and leveraging skills in API development and testing, enhanced deployment reliability by making image pinning explicit and reducing tag drift across different environments.
