65 Commits • 24 Features
Mar 1, 2026March 2026 monthly summary for keboola/mcp-server focused on reliability, extensibility, and business value. Delivered targeted fixes and major feature work across validation, tooling, metastore access, and semantic tooling, driving improved developer experience, reproducibility, and external integration readiness. Key outcomes include robust validation error handling with conversion to tool errors, code quality enhancements with isort formatting and explicit export of component tool functions, and UV lock synchronization to ensure reproducible installs. The metastore client was implemented, exported for external use, and accompanied by a comprehensive unit and integration test suite, with a version bump to 1.50.0. Semantic tooling gained core features, refactor, multi-model validation support, and expanded test coverage alongside documentation updates. Additional reliability improvements covered cron day-of-month validation, Snowflake query_data pagination fixes, and ongoing test stabilization and style/documentation maintenance.
