首先，感谢慢雾，很好的工具分享！！
反馈一个小问题，claude 中导入MasterMCP后，给MasterMCP发送请求时，发现claude中会有日志报错。
claude 相关日志如下：
2025-06-23T07:04:59.417Z [MasterMCP] [info] Message from server: {"jsonrpc":"2.0","id":24,"result":{"prompts":[{"name":"analyze_json","description":"Generate detailed analysis prompt for JSON data","arguments":[{"name":"url","required":true},{"name":"format_type","required":true}]}]}} { metadata: undefined }
2025-06-23T07:08:44.072Z [MasterMCP] [error] Unexpected token 'I', "INFO: "... is not valid JSON {
metadata: {

' at Readable.push (node:internal/streams/readable:392:5)\n' +
' at Pipe.onStreamRead (node:internal/stream_base_commons:189:23)'
}
}
分析原因：
MasterMCP log info日志写入stdio，与MCP Server采用的传输层stdio冲突，也就是MasterMCP会将收到的log也当做json来处理，所以触发上述问题。
解决方案：
在MasterMCP中奖log配置中增加stream设置为sys.stderr,与stdio区分开，避免日志数据和MCP传输的数据混淆。
Configure logging system
logging.basicConfig(
level=logging.INFO,
stream=sys.stderr,
format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
datefmt='%Y-%m-%d %H:%M:%S'
)
