import asyncio
from mcp import ClientSession
from mcp.client.sse import sse_client

async def main():
    async with sse_client("http://127.0.0.1:25560/sse") as (read, write):
        async with ClientSession(read, write) as session:
            await session.initialize()
            tools = await session.list_tools()
            print([t.name for t in tools.tools])

asyncio.run(main())
