# Open Computer Use for Hermes
开源 macOS Computer Use 服务,基于 Accessibility API,通过 MCP 协议暴露给 AI Agent。
## 安装
```bash
npm i -g open-computer-use
```
若命令找不到:
```bash
npm config get prefix # 检查全局路径
ls {prefix}/bin/open-computer-use
```
## macOS 权限(关键坑)
需授权**两个**权限,对象是 `.app` 包而非 Terminal:
| 权限 | 授权对象 |
|------|---------|
| 辅助功能 | `{npm_prefix}/lib/node_modules/open-computer-use/dist/Open Computer Use.app` |
| 屏幕录制 | 同上 |
**常见错误**:只授权 Terminal → `list-apps` 能用但 `get_app_state` 报 permissionDenied。
原因:`list-apps` 只需 Accessibility,`get_app_state` 需 Screen Recording,必须给 `.app` 本身授权。
### 授权步骤
1. 系统设置 → 隐私与安全性 → 辅助功能 → "+" → 导航到 `.app` 路径
2. 屏幕录制 → 同上
3. 重启终端
### 验证
```bash
open-computer-use doctor
open-computer-use list-apps
open-computer-use snapshot com.apple.finder
```
## 配置 Hermes MCP
参考 `native-mcp` 技能,在 hermes MCP 配置中添加 stdio server:
```yaml
mcp_servers:
open-computer-use:
command: "/full/path/to/open-computer-use"
args: ["mcp"]
timeout: 120
connect_timeout: 60
```
路径获取:`npm config get prefix` → 拼接 `/bin/open-computer-use`。
重启 hermes 或执行 `/reload-mcp`。
## 可用 MCP 工具
| 工具 | 功能 |
|------|------|
| `get_app_state` | 截图 + accessibility 树(**必须首先调用**) |
| `click` | 点击元素/坐标 |
| `drag` | 拖拽 |
| `type_text` | 输入文字 |
| `press_key` | 按键/快捷键 |
| `scroll` | 滚动 |
| `set_value` | 设置输入框值 |
| `list_apps` | 列出运行中的应用 |
| `perform_secondary_action` | 执行辅助操作 |
工具名在 hermes 中自动加前缀:`mcp_open_computer_use_{tool}`
## 排错
- **command not found**:用完整路径
- **permissionDenied on get_app_state**:权限给了 Terminal 没给 `.app`
- **doctor 超时**:手动去系统设置授权
- **MCP tools 未出现**:检查配置缩进,重启 hermes
