Overview

What is Robust new jupyter server?

This server provides a Docker-based client that connects to a Jupyter server using multi-collaborative protocol support, enabling MCP clients (such as Claude Desktop) to execute code in a Jupyter notebook.

How to use Robust new jupyter server?

Set up a Python 3.12.10 environment, install dependencies (jupyterlab, jupyter-collaboration, etc.), start a Jupyter server with a token, build the Docker image named notebook-client, and add the appropriate configuration to your Claude Desktop config.json. Key commands include jupyter lab --port 8888 --IdentityProvider.token MY_TOKEN --ip 0.0.0.0 and docker build -t notebook-client ..

FAQ from Robust new jupyter server

What dependencies are required?

Python 3.12.10, Docker, Git, and packages including jupyterlab, jupyter-collaboration, ipykernel, pycrdt, jupyter_server_ydoc, and the two client libraries.

How does authentication work?

The server uses a token set via --IdentityProvider.token MY_TOKEN. The same token must be passed as the TOKEN environment variable in the Docker client configuration.

What should I do if I get a WebSocketClosedError?

Delete the existing notebook.ipynb, create a new notebook from the Jupyter UI, and rename it to notebook.ipynb. This issue is known to occur on macOS.

How is the client configured for Claude Desktop?

Add an entry to config.json with command "docker" and arguments that run the container with environment variables for notebook path, server URL, and token.

Where does the notebook data live?

The notebook file (notebook.ipynb) resides on the host machine, and the client container reads/updates it over HTTP from the running Jupyter server.

Frequently asked questions

What dependencies are required?

Python 3.12.10, Docker, Git, and packages including jupyterlab, jupyter-collaboration, ipykernel, pycrdt, jupyter_server_ydoc, and the two client libraries.

How does authentication work?

The server uses a token set via `--IdentityProvider.token MY_TOKEN`. The same token must be passed as the `TOKEN` environment variable in the Docker client configuration.

What should I do if I get a WebSocketClosedError?

Delete the existing `notebook.ipynb`, create a new notebook from the Jupyter UI, and rename it to `notebook.ipynb`. This issue is known to occur on macOS.

How is the client configured for Claude Desktop?

Add an entry to `config.json` with command `"docker"` and arguments that run the container with environment variables for notebook path, server URL, and token.

Where does the notebook data live?

The notebook file (`notebook.ipynb`) resides on the host machine, and the client container reads/updates it over HTTP from the running Jupyter server.
