🪐 ✨ Jupyter MCP Server

Jupyter MCP Server is a Model Context Protocol (MCP) server implementation that provides interaction with Jupyter notebooks 📓 running in a local JupyterLab 💻.

Start JupyterLab

Make sure you have the following installed. The modifications made on the notebook can be seen thanks to Jupyter Real Time Collaboration (RTC).

pip install jupyterlab jupyter-collaboration ipykernel

Then, start JupyterLab with the following command:

jupyter lab --port 8888 --IdentityProvider.token MY_TOKEN --ip 0.0.0.0 

[!NOTE]
The --ip is set to 0.0.0.0 to allow the MCP server running in a Docker container to access your local JupyterLab.

Usage with Claude Desktop

To use this with Claude Desktop, add the following to your claude_desktop_config.json:

[!IMPORTANT]
Ensure the port of the SERVER_URLand TOKEN match those used in the jupyter lab command.
The NOTEBOOK_PATH should be relative to the directory where JupyterLab was started.
