OpenAI Codex MCP 服务器集成依旧故障，用户反映每线程附加设置导致持续问题，修复公告仍为兑现
英文摘要
A user reports that OpenAI Codex's MCP server installation is broken, with servers installed in one thread becoming invisible in another. They spent four hours attempting to diagnose a configuration issue but concluded the feature is simply not functioning. A fix announced on June 9th has not been deployed in the Microsoft Store version. The per-thread attachment model for MCP servers is considered a design flaw; the user ultimately switched to Claude to complete the task.
