E2B Connector for AI agents.

Q: How do I manage my costs with the E2B MCP?

You can manage costs by using the kill tool to delete sandboxes as soon as your agent finishes its task. This ensures you only pay for the time your code is actually running.

Q: 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.

Why people use E2B

E2B Secure Sandboxing for AI Code Execution

This Connector changes that by giving your agent its own hands. Your agent can now spin up a Linux environment, run the script, and give you the results in one go. You stop being the middleman for copy-pasting and start being the person who just checks the final output.

What Vinkius changes

E2B gives your agent a secure, disposable workspace to execute any code it generates.

Use it from Claude, ChatGPT, Cursor or another AI client you already have.

01—03

3 capabilities in this set.

Part of 3 available through E2B.

01 Capability
Create sandbox
Use create_sandbox to spin up a new isolated cloud sandbox. This provides your agent with a fresh Linux environment that starts in 150ms.
02 Capability
Kill sandbox
Use kill_sandbox to permanently delete a sandbox and its files. This releases resources and helps you keep your costs down.
03 Capability
List sandboxes
Use list_sandboxes to see all active environments in your account. It helps you monitor resource usage and keep track of what's running.

Set up in minutes

Before you connect

Questions about E2B.

The practical details behind the request, access and result.

What does the E2B MCP actually do?

E2B provides a secure way for your AI agent to execute code in the cloud. It creates isolated Linux environments so your agent can run scripts without touching your personal computer.

Can I use the E2B MCP to run Python scripts?

Yes, you can use pre-configured templates to spin up environments that already have Python installed. This makes it easy for your agent to run data analysis or scripts immediately.

Is the E2B MCP safe for running untrusted code?

It is designed specifically for security. Each sandbox is an isolated microVM with its own kernel and filesystem, meaning the code can't escape to your main system.

How fast does E2B MCP spin up a sandbox?

The sandboxes are built for speed and typically start in about 150ms. This allows your AI agent to jump into a new task almost instantly.

Can I use the E2B MCP for Node.js projects?

Yes, there is a dedicated Node.js template. Your agent can spin up a workspace with Node pre-installed to run JavaScript applications or test your code.

How do I manage my costs with the E2B MCP?

You can manage costs by using the kill capability to delete sandboxes as soon as your agent finishes its task. This ensures you only pay for the time your code is actually running.

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 capabilities, 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.
