LangChain tools backed by cocoon microVM sandboxes

cocoonstack-sandbox-langchain

LangChain tools backed by cocoon microVM sandboxes: a CocoonToolkit claims one sandbox lazily on first tool use and exposes it as StructuredTools an agent can call — shell exec, file read/write, and directory listing, with disk state persisting across calls.

from cocoonsandbox_langchain import CocoonToolkit

with CocoonToolkit("10.0.0.5:7777", api_token="...") as kit:
    agent = create_react_agent(model, kit.get_tools())
    agent.invoke({"messages": [("user", "run the tests in /work")]})

from_checkpoint="ck_..." branches the sandbox from a checkpoint's captured moment instead of a clean template — agents resume from prepared state (dependencies installed, repo cloned) in milliseconds.

Sync-native (_run calls the stdlib-only cocoonstack-sandbox SDK directly); async agents get _arun bridged via asyncio.to_thread.
