Let me rewrite this headline following the rules.
Original: This is how I started using coding agents for DS/ML workflows [D]
Short summary
Lemma is an open-source MCP server that connects coding agents like Claude Code, Cursor, and Copilot CLI to live Jupyter kernels for DS/ML workflows, replacing static .ipynb file reads with real-time kernel access. It ships a rules-based persona enforcing ML best practices—baselines before complexity, time-ordered splits, seed everything—plus nine skills covering EDA, causal analysis, inference, leakage review, and more. Installation is a single npm command with clean uninstall, supporting VS Code, PyCharm, and JupyterLab.
