MCP Python Demo

LLM 使用的 deepseek-chat 因为只有v3有tools属性 (deepseek-reasoner是不行的)

chat_response = client.chat.completions.create(
    model="deepseek-chat", # 通过指定 model='deepseek-chat' 即可调用 DeepSeek-V3 V3有tools属性
    messages=messages,
    tools=available_tools,
    tool_choice="auto"
)

安装

pip install uv
# uv init mcp-demo-python
git clone [email protected]:guobinqiu/mcp-demo-python.git
cd mcp-demo-python
uv venv
source .venv/bin/activate
# uv add "mcp[cli]" httpx
# uv add mcp openai python-dotenv
# rm main.py

运行

运行前把.env文件里的OPENAI_API_KEY换成你自己的

source .venv/bin/activate
python client/main.py server/main.py
