About

Provides a health check and a get_weather tool to query current weather by city name via HTTP, designed for integration with Dify.

README

这是一个最小可用的 MCP Server,提供 2 个工具:

  • health:连通性检查
  • get_weather(location):按城市名查询当前天气

1)安装依赖

如果你有系统 Python:

pip install -r requirements.txt

如果你要使用 Codex 内置 Python 运行时:

C:\\Users\\86318\\.cache\\codex-runtimes\\codex-primary-runtime\\dependencies\\python\\python.exe -m pip install -r requirements.txt

2)启动 MCP Server

python server.py

默认监听:

  • Host:0.0.0.0
  • Port:8787
  • MCP URL:http://127.0.0.1:8787/mcp

可选环境变量覆盖:

  • MCP_HOST
  • MCP_PORT
  • MCP_PATH

示例:

$env:MCP_PORT='8800'; python .\\server.py

3)在本地 Dify 接入

在 Dify 的 MCP Server(HTTP)配置里填写:

  • Server URL:http://127.0.0.1:8787/mcp
  • Name:local-weather
  • Server ID:local_weather

保存后,Dify 应该能自动发现以下工具:

  • health
  • get_weather

4)调用示例

在 Agent 或 Workflow 中让模型调用:

  • health
  • get_weather,参数 location = "Shanghai"

5)常见问题

  • 如果 Dify 运行在 Docker 容器里,127.0.0.1 指向容器本身,不是宿主机。
    • 通常改用:http://host.docker.internal:8787/mcp
  • 如果连接失败:
    • 检查端口 8787 是否被占用
    • 检查防火墙规则
    • 确认 URL 包含 /mcp 路径
