Keboola MCP Server Updates: v1.38–v1.48
A comprehensive roundup of MCP Server improvements from v1.38 to v1.48, including AI-powered flow scheduling, role-based access controls, job log fetching, smarter search, and significant performance improvements.
We're excited to share a comprehensive roundup of improvements to the Keboola MCP Server, spanning versions 1.38 through 1.48. These updates bring new scheduling capabilities, role-based access controls, smarter search, and significant reliability improvements—making it easier than ever to interact with your Keboola projects through AI assistants like Claude, ChatGPT, and others.
AI-Powered Flow Scheduling
You can now schedule flows directly through your AI assistant using the new Scheduler API integration. Set up recurring runs with cron expressions, preview schedules before applying them, and manage multiple schedules per flow—all without leaving your conversation.
Role-Based Access & Read-Only Mode
The MCP Server now supports role-based access controls. Users with guest or read-only roles receive a tailored, read-only toolset, ensuring they can explore project data safely without making unintended changes. The share role now has access to the modify_flow tool.
Job Logs & Workspace Management
The get_jobs tool now supports log retrieval directly from the Storage API, letting you inspect execution logs without switching to the Keboola UI. Workspace creation is now scoped beneath configurations to support accurate billing attribution.
Smarter Search & Discovery
Search capabilities have been expanded significantly. You can now search across configurations, column names, and column descriptions—making it easier to find the exact data assets you need. Tool prompting now favors search over enumeration for better performance and more relevant results.
Data App Improvements
Data apps now support the is_disabled parameter for toggling app state, and SQL and data type guidelines have been added to the modify_data_app tool to help prevent common mistakes. Data apps are also automatically disabled on dev branches.
Performance & Reliability
Table and bucket listings now use a compact output format, reducing response sizes and improving readability. Retry logic with exponential backoff has been added to handle deadlock errors gracefully. Queries are automatically cancelled on timeout to prevent resource waste, and the Streamable-HTTP transport now uses stateless mode for improved compatibility.
Note: the legacy SSE transport is deprecated and will be removed on March 31, 2026. We recommend migrating to Streamable-HTTP now.
