MCP Server Weather
基于和风天气API的一个获取实时天气的MCP服务端,使用Java来实现。和风天气API文档:https://dev.qweather.com/docs/api/weather/weather-now/
可用的工具列表
- 获取实时天气
getWeather
使用方法
- 下载项目到本地
- 打包项目,生成jar包
mvn clean package -Dmaven.test.skip=true
Claude使用方法:
{
"mcpServers": {
"mcp-server-weather": {
"command": "java",
"args": [
"-Dspring.ai.mcp.server.stdio=true",
"-jar",
"你的jar包路径",
"--weather.api.api-key=YOUR API KEY"
]
}
}
}
