Headless sandbox control for Claude Code

Use `create_sandbox` to spawn isolated Linux runtimes from your terminal. It works perfectly for automated pipelines where you need a clean environment. Claude Code can specify the template to use, such as Python or Node. This makes it easy to switch environments based on the project requirements.

Track active environments via CLI

The `list_sandboxes` tool outputs a list of currently running microVMs. This is essential for monitoring your resources during CI/CD tasks. You can pipe this output to other tools to manage your infrastructure. It keeps your terminal workflow efficient and transparent.

Destroy sandboxes on command

Run `kill_sandbox` to stop and delete any active environment. It ensures that your temporary compute resources are wiped cleanly. This is critical for automated scripts that shouldn't leave orphaned processes behind. It keeps your cloud usage predictable and cheap.

Common questions about E2B MCP in Claude Code

Use the add command with the server URL and transport flags. Once registered, the tools will be available for use in your terminal.

Yes, the server uses Firecracker microVMs to isolate execution. Your terminal environment is shielded from whatever code runs inside the sandbox.

E2B only manages the ephemeral state of your sandbox. It does not persist your code or project files once the session is terminated.

You should include the kill tool at the end of your scripts. This ensures that every sandbox is destroyed immediately after your task completes.

Yes, you can create and list multiple sandboxes concurrently. Just make sure to track their IDs so you can kill them when finished.
