使用方法

启动服务端

python main.py

客户端调用示例

from mcp import ClientSession, StdioServerParameters
from mcp.client.stdio import stdio_client
import asyncio

async def main():
    server_params = StdioServerParameters(
        command="python",
        args=["main.py"],
        env=None,
    )
    async with stdio_client(server_params) as (read, write):
        async with ClientSession(read, write) as session:
            await session.initialize()
            result = await session.call_tool(
                "recognize_captcha",
                arguments={"image_path": "E:/code/bug/service/ocr/captchaImage.jpg"}
            )
            print("识别结果:", result)

if __name__ == "__main__":
    asyncio.run(main())

工具接口

• recognize_captcha(image_path: str)
  识别本地图片验证码，返回内容对象
