快速开始

环境要求

  • Python >= 3.10
  • uv (推荐) 或 pip

安装

  1. 克隆项目:
git clone https://github.com/chenchen0611/mcp-python-demo.git
cd mcp-python-demo
  1. 使用 uv 安装依赖:
uv venv
source .venv/bin/activate  # Linux/Mac
# 或
.venv\Scripts\activate  # Windows
uv pip install -e .

配置

  1. 创建 .env 文件并配置必要的环境变量:
# 智谱AI配置
ZHIPU_API_KEY="your-zhipu-api-key"
ZHIPU_MODEL="glm-4-plus"
ZHIPU_BASE_URL="https://open.bigmodel.cn/api/paas/v4/"

# 腾讯地图API配置
TENCENT_MAP_API_KEY="your-tencent-map-api-key"
TENCENT_MAP_API_BASE="https://apis.map.qq.com/ws/"

运行

Web 界面(推荐)

cd src/mcp_python_demo
streamlit run web_client.py

访问以下地址之一:

  • 本地访问:http://localhost:8501
  • 局域网访问:http://[your-local-ip]:8501
  • 外网访问:http://[your-public-ip]:8501
页面配置
  • 直接输入server.py,点击连接 config
  • 新建一个terminal,运行下方命令然后在web页面输入http://127.0.0.1:8000
    cd src/mcp_python_demo
    uv run server.py
    
    config

命令行界面

cd src/mcp_python_demo
# 使用本地服务器
uv run client.py --agent server.py

# 或使用远程服务器
uv run server.py
uv run client.py --agent http://127.0.0.1:8000

config

可用工具

1. 天气查询

async def query_weather(adcode: str, search_type: str = "now") -> str:
    """获取中国城市天气信息"""

2. 地理编码查询

async def query_adcode(region_name: str) -> str:
    """获取行政区划代码"""

3. 网络搜索

async def web_search(search_query: str, search_engine: str = "search_std") -> str:
    """使用智谱AI进行网络搜索"""

开发说明

添加新工具

  1. 在 server.py 中使用 @mcp.tool() 装饰器添加新工具:
@mcp.tool()
async def your_tool(param1: str, param2: str = "default") -> str:
    """工具描述"""
    # 实现逻辑
    return result
  1. 工具会自动在客户端可用

环境变量

  • 所有敏感信息和配置都应该放在 .env 文件中
  • 不要将 .env 文件提交到版本控制系统
  • 参考 .env.example 进行配置

常见问题

  1. 连接错误

    • 检查服务器地址是否正确
    • 确认所有环境变量都已正确配置
    • 确保服务器正在运行且端口可访问
  2. API 调用失败

    • 验证 API 密钥是否有效
    • 检查网络连接
    • 确认 API 调用频率是否超限
  3. Web UI 无法访问

    • 检查防火墙设置
    • 确认端口是否开放
    • 验证服务器 IP 地址是否正确
