E2B Advanced Features

Preview Documentation

This section is in preview and not fully ready. The features and instructions may change in future releases.

MiroFlow provides advanced E2B (Execute to Build) sandbox capabilities for enhanced code execution environments with pre-installed packages and custom configurations.

---

Local E2B Sandbox Deployment

Recommended Setup

To achieve our best benchmark results, we recommend using a pre-defined sandbox template that includes the most commonly used Python and apt packages.

If you prefer not to use a sandbox template, you can disable it by commenting out the line template=DEFAULT_TEMPLATE_ID, in libs/miroflow-tool/src/miroflow/tool/mcp_servers/python_server.py (line 145).

Sandbox Setup Guide

Prerequisites

• npm installed locally
• Docker running locally
• E2B API key configured

Step 1: Install E2B CLI

Install E2B Command Line

# Install e2b
npm install -g @e2b/cli

# Verify installation
which e2b 

Step 2: Download Pre-configured Dockerfile

Download our pre-configured Dockerfile from the repository:

Download Dockerfile

wget https://github.com/MiroMindAI/MiroFlow/blob/main/docs/e2b.Dockerfile

Step 3: Build Template

Run the e2b template build command to create your custom template:

Build E2B Template

# Set your E2B access token
E2B_ACCESS_TOKEN=${your-token}

# Build the template with docker build locally
e2b template build -c "/root/.jupyter/start-up.sh" -n "all_pip_apt_pkg" -d ./e2b.Dockerfile

# Verify template was built successfully
E2B_ACCESS_TOKEN=${your-token} e2b template list

Custom Templates

You can create your own custom sandbox template for specific use cases by following similar steps. For more information, refer to the E2B Docker documentation.

E2B Docker Configuration

This custom E2B Docker environment provides a sandboxed environment with pre-installed scientific computing libraries, data analysis tools, and dependencies commonly needed for AI agent tasks.
