Use with Langchain

It can also be used as Langchain tool. Try below code to try

import httpx
import asyncio
from langchain.tools import Tool
from brave_mcp_langchain import brave_tool

async def test_search():
    result = await brave_tool.search_tool.ainvoke({"query": "LangGraph overview", "max_results": 10})
    print(result)

    result = await brave_tool.fetch_content_tool.ainvoke({
        "url": "https://iamatulsingh.github.io"
    })
    print(result)

asyncio.run(test_search())
