LangChain tool for Sandflare Firecracker microVM sandboxes — run agent-generated code safely

sandflare-langchain

LangChain tool integration for Sandflare — run agent-generated code in isolated Firecracker microVM sandboxes.

Installation

pip install sandflare-langchain

Usage

from langchain.agents import AgentExecutor, create_openai_tools_agent
from langchain_openai import ChatOpenAI
from sandflare_langchain import SandflareCodeInterpreter

tool = SandflareCodeInterpreter(api_key="sf-...")

llm = ChatOpenAI(model="gpt-4o")
agent = create_openai_tools_agent(llm, [tool], prompt)
executor = AgentExecutor(agent=agent, tools=[tool])

result = executor.invoke({"input": "Plot a sine wave and save it as plot.png"})

How it works

Each tool call creates a fresh Sandflare microVM sandbox, executes the code, streams stdout/stderr back to LangChain, and auto-deletes the sandbox when done.
