python code --mcp server tools

bash 复制代码

import logging

from mcp.server.fastmcp import FastMCP

logging.basicConfig(
    level=logging.INFO,
    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s'
    )
logger: Final = logging.getLogger(__name__)
# Create an MCP server
mcp: FastMCP = FastMCP("Demo", json_response=True)

# Add an addition tool 
@mcp.tool()
def add(a: int, b: int) ->int:
    """计算两个数相加的结果"""
    return a + b

# Add a dynamic greeting resource
@mcp.resource("greeting://{name}")
def get_greeting(name: str) -> str:
    """Return a greeting message for the given name"""
    return f"Hello, {name}!"

def main():
#   print("Hello from mcpserver!")    
    #mcp.run(transport="streamable-http") ## sse
    try:
        logger.info("正在启动MCP服务器...")
        mcp.settings.host = "0.0.0.0"
        mcp.run(transport="streamable-http") # sse stdio streamable-http
    except KeyboardInterrupt:
        logger.info("接收到中断信号，正在关闭服务器...")
    except Exception as e:
        logger.error(f"服务器运行时发生错误: {str(e)}", exc_info=True)
        raise
    finally:
        logger.info("服务器已关闭")
 
if __name__ == "__main__":
    main()

使用不同的协议需要更改代码：

mcp.run(transport="sse")

stdio

mcp.run(transport="stdio")

streamable-http

mcp.run(transport="streamable-http")

启动

python main.py

测试

测试发送消息：计算两个数相加的结果,1加3等于几

思考过程：

结果：

python 创建与发布

**mcp-server

mk mcp_server && cd mcp_server
uv init . -p 3.13 3.13.4
uv add "mcp[cli]"

写完程序后，测试OK,打包
type：stdio 发布方式：
uv build
然后发布到：https://pypi.org，申账号，邮件认证，保存好验证码：，下载微软认证工具，双重认证一下，apikey token
uv publish --token apikey

type:sse 发布方式;
将main.py 文件和pyproject.toml 得制到服务器中的目录，
然后执行：uv venv ,
再执行uv pip install .
再然后，uv run main.py
