Jupyter notebooks are the scratchpads that analysts and researchers use for charts and calculations. This server hands your assistant the keys to one you already have running: it can add cells, run them, read what comes back including plots and images, retry a cell that failed, and move between several notebooks in one sitting. It works in Claude Desktop, Cursor, VS Code, Cline and Windsurf. You need a running Jupyter server and its access token.

jupyter-mcp-server FAQ

Which apps does this work in?

Claude Desktop, Cursor, VS Code, Cline and Windsurf are all listed as supported.

Do I need an access token?

Yes. You point it at a running Jupyter server and give it that server's token.

Can I use this to fix a notebook cell that keeps erroring?

Yes — it reads the error that comes back, rewrites the cell and runs it again.

Is setup hard?

It is developer level. You need Jupyter running somewhere, plus Docker, pip or uvx to start the server.

Can it see plots and images?

Yes. Picture output is supported as well as text, so charts come back as pictures.

Does it work with more than one notebook?

Yes, you can switch between open notebooks without restarting anything.
