开源安卓应用 Buddy 让 Codex 操控手机
AI 总结
开发者 /u/3amae404 在 r/OpenAI 发布开源应用 Buddy（Apache 2.0），它以一个悬浮聊天气泡的形式运行在 Android 上，用户下达指令后由 Codex 读取屏幕并在各应用中点击、输入。据开发者介绍，Codex CLI 运行在应用内置的小型 Linux 环境中，无需 root 或 Termux，并通过 Android 无障碍服务把手机能力作为 MCP 工具暴露出来；应用使用用户的 ChatGPT 套餐登录，Claude Code 和 OpenCode 也可使用。对于发送、发布或购买类操作，应用会先弹出审批卡片，且授权仅对当次具体消息有效，未获批准的通知回复会留在列表中而不会发出。
深度见解
该应用展示了如何借 Android 无障碍服务把手机变成 Codex CLI 的 MCP 工具，并为发送、发布或购买等敏感操作设置逐条审批。
| Buddy is a floating chat bubble on Android. You tell it what you want, and Codex does it on the phone: it reads the screen and taps and types in your apps. In the video: Codex turns on my living room lights (you can see the approval card), and OpenCode on a free model adds a Switch 2 to my Amazon cart. Things it handles: replying to messages, filling in forms, digging through settings, and notification rules that draft an answer when a chat comes in. How it works: Codex CLI runs in a small Linux inside the app (no root, no Termux) and gets the phone as MCP tools through Android's accessibility service. It signs in with your ChatGPT plan. Claude Code and OpenCode work too if you want to compare. The part I spent the most time on: anything that sends, posts or buys shows an approval card first, and the OK only covers that exact message. A notification reply you don't approve waits in a list instead of going out.
