langchain-capsule 0.1.1

Capsule sandbox integration for LangChain — run code in isolated WebAssembly sandboxes

langchain-capsule

Capsule integration for LangChain.

What is this?

langchain-capsule gives LangChain agents the ability to safely execute Python and javascript code in an isolated WebAssembly sandbox.

The WebAssembly sandbox files (.wasm) are already bundled inside this package; no configuration or network request is necessary to execute the sandboxes dynamically.

Installation

pip install langchain-capsule

Usage

The package provides tools for executing code inside an isolated environment.

import asyncio
from langchain_capsule import CapsulePythonTool, CapsuleJSTool

# Python Example
python_tool = CapsulePythonTool()
result = python_tool.run("1 + 1")
print(result) # "2"

# JavaScript / TypeScript Example
js_tool = CapsuleJSTool()
result = asyncio.run(js_tool.arun("1 + 2"))
print(result) # "3"
