ipybox is a unified execution environment for Python code, shell commands, and programmatic MCP tool calls.
Overview
ipybox executes code blocks in a stateful IPython kernel. A code block can contain any combination of Python code, shell commands, and programmatic MCP tool calls. Kernels can be sandboxed with sandbox-runtime, enforcing filesystem and network restrictions at OS level.
It generates Python APIs for MCP server tools via mcpygen, and supports application-level approval of individual tool calls and shell commands during code execution. ipybox runs locally on your computer, enabling protected access to your local data and tools.
[!NOTE] Next generation ipybox This is the next generation of ipybox, a complete rewrite. Older versions are maintained on the [0.6.x branch](https://g

SAFEgrade B · trust 89/100 Nothing in the source contradicts what it says it does. Grade A is reserved for packages that have also passed the behavioural sandbox.

The server itself is configured with permissions to access all files in the current directory (`"."`), but the sandbox additionally blocks read access to `.env`. The sandbox also allows access to `reg

Questions
What is the Ipybox MCP server?
Unified execution environment for Python code, shell commands, and programmatic MCP tool calls.
Is Ipybox safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does Ipybox need?
No credential environment variables were found in its source, so it appears to need none.
How does Ipybox run?
It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on PyPI as ipybox.
How current is this page?
The grade is for one exact copy of the source (5f460cfb3a07), read on 2026-10-07. The repository is watched and re-audited when it changes.
