E2B MCP Gateway

Run multiple isolated MCP servers together in a single E2B sandbox, powered by Groq's ultra-fast inference.

What is E2B MCP Gateway?

E2B's MCP Gateway provides a unified interface to run multiple Model Context Protocol (MCP) servers inside isolated sandboxes. Instead of connecting to each MCP server separately, E2B creates a single gateway endpoint that routes requests to all configured MCPs—giving your AI access to 200+ tools through one connection.

Key Features

• Unified Gateway - One endpoint for multiple MCP servers (Exa, Browserbase, Notion, etc.)
• Isolated Sandboxes - Each workflow runs in its own secure Linux environment
• Combined Capabilities - Mix search, browser automation, data storage, and more
• Type-Safe - Full TypeScript/Python SDK support
• Fast Setup - Configure multiple MCPs in seconds

Quick Start

1. Sign up for services:
   • E2B - Get API key for sandbox management
   • Browserbase - Get API key + Project ID for browser automation
   • Exa - Get API key for web search
   • Groq - Get API key for LLM inference

All services have a free tier that is enough for this demo.

2. Install dependencies:

   pip install e2b openai

3. Set environment variables:

   export E2B_API_KEY='your_e2b_key'
   export BROWSERBASE_API_KEY='your_browserbase_key'
   export BROWSERBASE_PROJECT_ID='your_project_id'
   export EXA_API_KEY='your_exa_key'
   export GROQ_API_KEY='your_groq_key'

4. Run the notebook - Open mcp-e2b.ipynb to see it in action

Why E2B + Groq?

E2B's Advantage: Instead of managing separate connections to Exa's MCP, Browserbase's MCP, and others, E2B creates one gateway that hosts them all. Your AI agent can seamlessly use web search, browser automation, and any other MCP tool through a single endpoint.

Groq's Speed: With up to 500+ tokens/second, Groq handles tool orchestration and response generation in milliseconds—making multi-step research workflows feel instant.
