What is Magic Skill?

Magic Skill is a bridge between Cursor Agent and your real desktop. It combines:

Component	Role	Stack
Magic Mouse	A Cursor-style desktop pet that roams your screen, shows status, and physically moves mouse & keyboard	Tauri 2 · Rust · Svelte
Magic Skill (MCP)	Cursor Skill + MCP server — exposes 17+ mm_* tools to the Agent	Node 20+ · TypeScript · MCP SDK

You in Cursor  →  Agent calls mm_* tools  →  MCP Server  →  ws://127.0.0.1:3721  →  Magic Mouse  →  Windows OS

Inspired by Codex Computer Use and Agent-S: screenshot → reason → single action → verify → loop (≤30 steps).

Features

• 🐭 Desktop pet — Cursor isometric cube avatar, roam, drag, double-tap reactions
• 🖱️ Full computer use — screenshot, click, type, hotkey, scroll, drag, app launch, window focus
• 🤖 Cursor integration — auto Skill install, MCP registration, local token pairing
• 🛡️ Safety first — localhost-only Hub, audit log, approval gates, Ctrl+Shift+. emergency stop
• 💬 DeepSeek tab — optional on-device API chat in the pet panel
• 📋 Clipboard history, custom YAML actions, i18n UI

Quick start (developers)

npm run setup
npm run dev:mouse      # Vite :1420 + Hub :3721

Verify in Cursor:

Click pet / tray icon	Open Magic Mouse panel
Double-click pet	Poke animation
Ctrl+Alt+P	Toggle panel
Drag pet	Move (position persisted)
Ctrl+Shift+.	Emergency stop
Ctrl+Shift+Y / N	Approve / deny pending action

Safety

• WebSocket binds to 127.0.0.1 only, token-authenticated
• Mutating actions logged to ~/.magic-skill/audit.log
• Destructive ops require user approval in the pet panel

Magic Skill 是什么？

Magic Skill 让 Cursor Agent 拥有操作你整台电脑的能力。它由两部分组成：

组件	作用	技术栈
Magic Mouse	Cursor 风格桌宠，在桌面上漫游、展示状态，并驱动真实鼠标键盘	Tauri 2 · Rust · Svelte
Magic Skill (MCP)	Cursor Skill + MCP 服务，向 Agent 暴露 17+ 个 mm_* 工具	Node 20+ · TypeScript · MCP SDK

你在 Cursor 说话  →  Agent 调用 mm_*  →  MCP Server  →  ws://127.0.0.1:3721  →  Magic Mouse  →  操作系统

设计思路融合 Codex Computer Use 与 Agent-S：截图 → 推理 → 单步动作 → 验证 → 循环（约 ≤30 步）。

核心功能

• 🐭 桌面宠物 — Cursor 立体方块形象，漫游、拖动、双击互动
• 🖱️ 完整 Computer Use — 截图、点击、输入、快捷键、滚动、拖拽、启动应用、聚焦窗口
• 🤖 Cursor 深度集成 — 自动安装 Skill、写入 MCP、本地令牌配对
• 🛡️ 安全可控 — 仅本机 Hub、审计日志、操作审批、Ctrl+Shift+. 紧急停止
• 💬 问 DeepSeek — 面板内可选的本机 API 对话
• 📋 剪贴板历史、YAML 自定义动作、中英界面

开发者快速开始

npm run setup
npm run dev:mouse      # Vite :1420 + Hub :3721

在 Cursor 聊天验证：
