An MCP server for computer use on native desktop and mobile apps — macOS, Windows, Android, and Chrome/Electron via CDP.
Add to your client in one click:
Claude Code: claude mcp add native-devtools -- npx -y native-devtools-mcp
native-devtools-mcp gives AI agents and MCP clients direct control over native desktop apps, Chrome/Electron browsers, and Android devices — screenshots, OCR, accessibility-first element lookup, input simulation, window management, Chrome DevTools Protocol (CDP), and ADB — all in one local server. Works with Claude Desktop, Claude Code, Cursor, and other MCP-compatible clients.
Quickstart
npx -y native-devtools-mcp
🚀 Features
- 👀 Computer Vision: Screenshots of screens, windows, or regions with built-in OCR (Vision on macOS, Windows Media OCR on Windows).
- 🖱️ Input Simulation: Click, drag, scroll, type — global coordinates, window-relative, and screenshot-relative targeting.
- 🎯 Element-Precise AX Dispatch (macOS):
take_ax_snapshot→ax_click/ax_set_value/ax_select— dispatch against Accessibility-tree elements without moving the mouse or stealing focus. The preferred path for native macOS apps. - 🌐 Browser Automation (CDP): Chrome DevTools Protocol for Chrome and Electron apps (Signal, Discord, VS Code, Slack) — DOM-level click, fill, navigate, and JS evaluation without a separate Node.js server.
- 📱 Android (ADB): Screenshots, uiautomator-based text lookup, input, and app management over USB or Wi-Fi.
- 🧩 Template Matching:
load_image+find_imagefor icons, toggles, and custom controls OCR can't identify. - 🪟 Window Management: List, focus, launch, and quit apps; record windows as timestamped JPEG frames.
- 🔍 Hover Tracking: Observe user navigation patterns with dwell-filtered hover events — designed for LLMs watching a user work.
- 🔒 Local & Private: 100% local execution. Screenshots and input never leave your machine.
🧭 Three Approaches to Interaction
Pick the approach that matches your target app.
| Approach | Best for | Key tools |
|---|---|---|
| Visual (universal) | Any app — games, Qt, custom renderers, anything without an AX tree | take_screenshot, find_text, click, type_text, find_image |
| AX Dispatch (macOS — preferred for native macOS apps) | AppKit / SwiftUI apps — System Settings, Finder, Mail, Xcode, Notes | take_ax_snapshot, ax_click, ax_set_value, ax_select |
| CDP (Chrome / Electron) | Web content, Electron apps with --remote-debugging-port |
cdp_connect, cdp_find_elements, cdp_take_dom_snapshot, cdp_click, cdp_fill |
For macOS native apps, AX Dispatch is the preferred path — it's element-precise, doesn't move the mouse, and doesn't steal focus. See the Native App AX Dispatch recipe.
