快速开始
环境要求
- Python >= 3.10
- uv (推荐) 或 pip
安装
- 克隆项目:
git clone https://github.com/chenchen0611/mcp-python-demo.git
cd mcp-python-demo
- 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
- 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
- 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
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
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
- 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
- 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
-
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
-
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
-
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
