项目使用了deepseek的api_key,请在.env文件中添加你的api_key

如果使用其他LLM服务,请在env文件中添加相应的API_KEY,请选择支持MCP服务的LLM服务

创建虚拟环境

uv venv

# Activate virtual environment

# On Windows:
.venv\Scripts\activate

# On Unix or MacOS:
source .venv/bin/activate

安装依赖

## 使用openai格式来访问
uv add mcp openai python-dotenv

创建.env文件

touch .env

Add API key to .env file

echo "OPENAI_API_KEY=your_api_key" >> .env
echo "OPENAI_BASE_URL="https://api.deepseek.com/v1"" >> .env
echo "OPENAI_MODEL="deepseek-chat" >> .env

编辑server.json文件来指定mcp-server

{
    "servers": [
      {
        "command": "uv",
        "args": ["run","../server/tasklist.py"],
        "env": null
      },
      {
        "command": "uv",
        "args": ["run","../server/weather.py"],
        "env": null
      },
      {
        "command": "npx",
        "args": ["-y","../server/stock.js"],
        "env": null
      }
    ]
  }

运行mcp-demo

cd client
uv run client.py server.json

然后输入用户query即可
