Python 实现 MCP 客户端调用高德地图天气查询示例

Python SDK 客户端

安装依赖：

pip install mcp

代码示例：

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

server_params = StdioServerParameters(
    command="npx",
    args=["-y", "@amap/amap-maps-mcp-server"],
    env={"AMAP_MAPS_API_KEY": "xxxxx"}
)

async def run():
    async with stdio_client(server_params) as (read, write):
        async with ClientSession(read, write) as session:
            await session.initialize()
            tools = await session.list_tools()
            print("工具列表:", tools)
            result = await session.call_tool("maps_weather", arguments={"city": "福州"})
            print("调用结果:", result)

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