## Best for
Data work where an agent should run code and inspect results in a notebook you can watch.

## About Jupyter MCP Server
Datalayer's Jupyter MCP Server connects agents to Jupyter notebooks so they can add, edit and execute cells and read outputs in real time, against any Jupyter server you run, from a laptop to JupyterHub, or remote sandboxes. It is BSD-licensed and needs no account; Datalayer also offers a hosted endpoint and a Claude Code plugin.

## Connect to an MCP client
Launch command from the project's README: `JUPYTER_URL=http://localhost:8888 JUPYTER_TOKEN=<your-token> uvx jupyter-mcp-server@latest`

### Claude Code (Run in your terminal)

```shell
claude mcp add jupyter-mcp-server -e JUPYTER_URL=http://localhost:8888 -e 'JUPYTER_TOKEN=<your-token>' -- uvx jupyter-mcp-server@latest
```
