Weather MCP Server

一个基于官方 MCP Python SDK FastMCP 的天气查询 MCP 服务器。服务通过 wttr.in 获取实时天气数据,支持中文城市名映射,也支持直接传入英文城市名。

功能

  • get_weather(city: str): 查询指定城市当前天气。
  • list_supported_cities(): 列出内置支持的中文城市。
  • get_server_info(): 查看服务器名称、版本、工具列表和数据来源。

环境要求

  • Python 3.10+
  • 可访问 https://wttr.in

本地运行

pip install -r requirements.txt
python server.py

服务器默认使用 stdio transport,适合由支持 MCP 的客户端以子进程方式启动。容器环境默认使用 streamable-http transport,监听 0.0.0.0:8000

MCP 客户端配置示例

{
  "mcpServers": {
    "weather": {
      "command": "python",
      "args": ["/absolute/path/to/weather_mcp_server/server.py"]
    }
  }
}

Docker 运行

docker build -t weather-mcp-server .
docker run --rm -i weather-mcp-server

如需在本地用 HTTP transport 运行:

MCP_TRANSPORT=streamable-http MCP_HOST=0.0.0.0 PORT=8000 python server.py

发布到 Smithery
