Claude Code finally works fine with Jupyter

Last year, I've had bad experiences of using Jupyter with Claude Code. Many others told me the same.

Recently, I tried it with the open source Jupyter MCP Server (no affiliation). Setup took a bit of fiddling, but once it was up, it worked really well.

The big difference is kernel access. Claude can now talk directly to my live IPython kernel and edit notebook cells properly (without messing the JSON).

I just let it write notebooks, run top to bottom, debug & fix errors & only ping me when everything is working.

Has anybody tried JupyterLab AI extensions (jupyter-ai, notebook-intelligence etc.) ? I wonder how those compare to my Jupyter MCP based workflow.
