# 🪐🔧 Jupyter MCP Server Sandboxes Extension

</div>

`jupyter_mcp_sandboxes` is an optional extension for
[jupyter-mcp-server](https://github.com/datalayer/jupyter-mcp-server) that adds
sandbox-backed code execution. It is discovered automatically through the
`reactor.mcp.extensions` entry point (powered by
[`reactor`](https://github.com/datalayer/reactor) and
[`reactor_mcp_server`](https://pypi.org/project/reactor-mcp-server/)) once
installed. Its four tools are in the `sandboxes` toolset, so a client that
wants them and nothing else connects to `/mcp?only=sandboxes`.

## Features

Installing this extension exposes four additional MCP tools:

- `launch_sandbox` — launch a code sandbox (`eval`, `docker`, `jupyter-server`,
  `datalayer`, `daytona`, `e2b`, `coreweave`, `cloudflare`, `google-colab`,
  `kaggle`, `monty`, `modal`).
- `list_sandboxes` — list launched sandboxes and their state.
- `use_sandbox` — select (or clear) the active sandbox used by `execute_code`.
- `terminate_sandbox` — stop and unregister a sandbox.

It also lets `SANDBOX_VARIANT` route the standard notebook/cell execution tools
through a non-`jupyter` backend via the sandbox's plain kernel client when the
selected variant exposes one.

## Installation

```bash
pip install jupyter_mcp_sandboxes
```

Backend-specific extras are provided by the underlying
[`code-sandboxes`](https://github.com/datalayer/code-sandboxes) package, e.g.:

```bash
pip install "code-sandboxes[modal]"       # Modal
pip install "code-sandboxes"              # Google Colab (included in base)
pip install "code-sandboxes[kaggle…
