langchain-e2b

Quick Install

After the package is published:

pip install langchain-e2b

from e2b import Sandbox

from langchain_e2b import E2BSandbox

sandbox = Sandbox.create()
backend = E2BSandbox(sandbox=sandbox)

try:
    result = backend.execute("echo hello")
    print(result.output)
finally:
    sandbox.kill()

What is this?

langchain-e2b adapts an existing E2B sandbox to the Deep Agents sandbox protocol. It uses the low-level e2b SDK so Deep Agents can run shell commands and move files through the standard Deep Agents backend interface.

This package intentionally does not hide E2B sandbox lifecycle management. Use the E2B SDK to create, connect to, configure, and kill sandboxes, then pass the connected sandbox object to E2BSandbox.

Contributing

Contributions are welcome. Keep the adapter focused on implementing the Deep Agents sandbox backend protocol over the official E2B SDK.
