简单MCP Client实现

使用 uv 创建项目和依赖

uv init mcp-client-demo

uv add "mcp[cli]"

pip install mcp

编写 mcp_client.py

from mcp import ClientSession, StdioServerParameters
from mcp.client.stdio import stdio_client

# Create server parameters for stdio connection
server_params = StdioServerParameters(
command="python", # Executable
args=[
"mcp_demo1.py"
],# Optional command line arguments
env=None # Optional environment variables
)

async def run():
async with stdio_client(server_params) as (read, write):
async with ClientSession(read, write) as session:
# Initialize the connection
await session.initialize()

            # List available tools
            tools = await session.list_tools()
            print("Tools:", tools)

            # call a tool
            score = await session.call_tool(name="get_weather",arguments={"city": "上海"})

            print("weather: ", score)

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

运行代码，可以看到输出
