These are the exact actions your AI can choose when you ask it to work with E2B.

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through E2B.

  1. 01

    List sandboxes

    Useful for monitoring active environments and managing resources. List all currently active sandboxes in your E2B account

  2. 02

    Create sandbox

    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

  3. 03

    Kill sandbox

    The sandbox and its filesystem contents are permanently deleted. Terminate a running sandbox by its ID

Connect your client

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 3 capabilities arrive ready to run.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of E2B, so you can see the experience inside your AI.

It does not authenticate your account with E2B. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ

Questions E2B owners ask.

  • 01

    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.

  • 02

    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.

  • 03

    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.
