使用说明

气象桥MCP

春靴 模型上下文协议（MCP）服务器 它将实时天气数据与 OpenWeatherMap AI代理。将其连接到 克劳德桌面版 或 克劳德代码 用简单的英语问天气问题——客服会自动调用正确的工具。

"What's the weather in Tokyo?" → getCurrentWeather("Tokyo") → 18°C, partly cloudy
"3-day forecast for Berlin?"   → getForecast("Berlin", 3)  → Mon 12°C, Tue 10°C, Wed 14°C

MCP工具

工具 说明 参数
getCurrentWeather 一个城市的现状 city --例如。 "London"
getForecast 多日预报 city, days (1–5)

这两个工具都返回了一个人类可读的摘要，人工智能模型使用该摘要来编写其响应。

快速开始

使用Docker （不需要Java）：

git clone https://github.com/mm-camelcase/weather-bridge-mcp.git
cd weather-bridge-mcp
cp .env.example .env           # add your OPENWEATHERMAP_API_KEY
docker-compose up

连接克劳德桌面 --添加到 ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "weather-bridge": {
      "type": "sse",
      "url": "http://localhost:8080/sse"
    }
  }
}

重新启动Claude Desktop并询问： “纽约的天气怎么样？”

看 claude-config/README.md 有关Claude Code（CLI）设置说明。

入门指南（不含Docker）

先决条件

配置

cp .env.example .env
# edit .env — set OPENWEATHERMAP_API_KEY=your_key_here
export $(cat .env | xargs)

或者直接设置属性：

mvn spring-boot:run -Dopenweathermap.api-key=your_key_here

跑

mvn spring-boot:run

验证服务器是否已启动：

curl http://localhost:8080/weather/health
# → {"status":"UP","service":"weather-bridge-mcp"}

手动工具测试（无需MCP客户端）：

curl "http://localhost:8080/weather/current/London"
curl "http://localhost:8080/weather/forecast/Paris?days=3"
