### Description (declared)

# Sandbox MCP

<!-- mcp-name: io.github.scooter-lacroix/sandbox-mcp -->

> General-purpose Python execution sandbox for MCP clients, with persistent execution, artifact capture, Manim rendering, guarded shell access, and lightweight web app workflows.

Sandbox MCP is designed to stay broadly useful across coding assistants and MCP directories. It can run Python, generate plots and files, render Manim animations, launch or export small Flask/Streamlit demos, and expose prompts/resources that help an LLM discover how to use the sandbox well.

## 🎬 Demo: Manim Animation in Action

See the Sandbox MCP server creating beautiful mathematical animations with Manim:

</div>

**Alternative formats**: [MP4 Video](examples/SquareToCircle.mp4) | [GIF Animation](examples/SquareToCircle.gif)

*Example: 3D mathematical animation generated automatically by the sandbox*

## 🚀 Quick Start

```bash
# Clone the repository
git clone https://github.com/scooter-lacroix/sandbox-mcp.git
cd sandbox-mcp

# Install with uv (recommended)
uv venv && uv pip install -e .

# Run the MCP server
uv run sandbox-server-stdio
```

## ✨ Features

### 🔧 **Enhanced Python Execution**
- **Code Validation**: Automatic input validation and formatting
- **Virtual Environment**: Auto-detects and activates `.venv`
- **Persistent Context**: Variables persist across executions
- **Enhanced Error Handling**: Detailed diagnostics with colored output
- **Interactive REPL**: Real-time Python shell with tab completion

### 🎨 **Intelligent Artifact Management**
- **Automatic Capture**: Matplotlib plots and PIL images…
