What is the E2B MCP Server?
Connect your AI agent to E2B — the leading sandbox platform for AI code execution, trusted by OpenAI, Anthropic, and thousands of AI companies.
What you can do
- Create Sandboxes — Spin up isolated Linux environments in ~150ms. Each sandbox is a Firecracker microVM with its own kernel, filesystem, and network
- List Sandboxes — Monitor all active sandbox environments, their templates, and resource usage
- Kill Sandboxes — Terminate environments when done to release resources and reduce costs
How it works
- Subscribe to this server
- Enter your E2B API key ($100 free credits to start)
- Your agent can now create and manage isolated code execution environments
Who is this for?
- AI Agent Developers — give agents a safe place to execute generated code without risking your infrastructure
- Data Science Teams — run analysis scripts in isolated environments with guaranteed reproducibility
- EdTech Platforms — let students execute code in sandboxed environments with full isolation
Built-in capabilities (3)
The sandbox is an isolated Linux VM that starts in ~150ms. Use templates like "base" (default), "python3", or "node" for pre-configured environments. Default timeout is 300 seconds. Create a new isolated cloud sandbox for running code securely. Each sandbox is a Firecracker microVM with its own filesystem
The sandbox and its filesystem contents are permanently deleted. Terminate a running sandbox by its ID
Useful for monitoring active environments and managing resources. List all currently active sandboxes in your E2B account
Why Pydantic AI?
Pydantic AI validates every E2B tool response against typed schemas, catching data inconsistencies at build time. Connect 3 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.
- —
Full type safety: every MCP tool response is validated against Pydantic models, catching data inconsistencies before they reach your application
- —
Model-agnostic architecture. switch between OpenAI, Anthropic, or Gemini without changing your E2B integration code
- —
Structured output guarantee: Pydantic AI ensures tool results conform to defined schemas, eliminating runtime type errors
- —
Dependency injection system cleanly separates your E2B connection logic from agent behavior for testable, maintainable code

Frequently asked questions
How secure are E2B sandboxes?
E2B sandboxes run as dedicated Firecracker microVMs — the same technology used by AWS Lambda and Fargate. Each sandbox has its own Linux kernel, filesystem, and network stack, providing hardware-level isolation. Code running in a sandbox cannot access your host system, other sandboxes, or any external resources unless explicitly configured.
What programming languages are supported?
E2B supports Python, JavaScript/TypeScript, R, Java, and Bash out of the box. You can also create custom sandbox templates with any pre-installed tools, libraries, or system dependencies. The base template provides a full Ubuntu Linux environment where you can install anything via apt or pip.
How does E2B pricing work?
E2B uses usage-based pricing billed per second of compute time. The free Hobby plan includes a one-time $100 credit (no credit card required), up to 20 concurrent sandboxes, and 1-hour maximum session length. The Pro plan starts at $150/month with 24-hour sessions and higher concurrency limits.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your E2B MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
