E2B MCP Server

Production-grade Model Context Protocol servers that enable AI assistants to execute code securely in isolated E2B sandboxes. Bring powerful code interpretation capabilities to Claude Desktop, Cline, and other MCP-compatible clients.

Demo • JavaScript Docs • Python Docs • E2B Platform

Overview

This repository contains production-ready MCP server implementations in both JavaScript/TypeScript and Python. Each server provides a complete toolkit for AI models to interact with secure, isolated code execution environments.

What you can do:

• Execute Python code in Jupyter-style notebooks
• Run shell commands in isolated environments
• Manage files (read, write, list) within sandboxes
• Expose services running in sandboxes via public URLs
• Manage multiple concurrent sandboxes with automatic cleanup
• Monitor sandbox usage with comprehensive logging

Key features:

• 10 Production Tools: Complete sandbox interaction toolkit
• Resource Management: Automatic lifecycle management with configurable limits
• Type Safety: Full validation with Zod (JS) and Pydantic (Python)
• Robust Error Handling: Clear diagnostics and graceful degradation
• Production Logging: Multi-level logging with timestamps
• Graceful Shutdown: Proper cleanup on termination signals

Quick Start

Manual Installation

JavaScript/TypeScript

Security

E2B sandboxes provide secure, isolated execution environments. However, always:

• Keep your E2B API key secure and never commit it to version control
• Use environment variables for sensitive configuration
• Monitor sandbox usage and set appropriate limits
• Review code before execution in production environments

For security concerns, please email security@e2b.dev.
