What is mcp_use?

mcp_use is an open source library that enables developers to connect any LLM to any MCP server, allowing the creation of custom agents with tool access without relying on closed-source or application-specific clients.

Just like this

import asyncio
from langchain_openai import ChatOpenAI
from mcp_use import MCPAgent, MCPClient

async def main():
    client = MCPClient(config= {"mcpServers":{
    "playwright": {
        "command": "npx",
        "args": ["@playwright/mcp@latest"],
        "env": {"DISPLAY": ":1"}
    }}})
    # Create LLM
    llm = ChatOpenAI(model="gpt-4o", api_key=...)
    # Create agent with tools
    agent = MCPAgent(llm=llm, client=client, max_steps=30)
    # Run the query
    result = await agent.run("Find the best restaurant in San Francisco")

if __name__ == "__main__":
    asyncio.run(main())
