ScreenHand: AI Agent Desktop Automation via MCP

Open-source MCP server for AI agent desktop automation across macOS and Windows apps + Chrome workflows.

Comment

What is ScreenHand?

ScreenHand is an open-source MCP server that gives AI agents real desktop control: screen understanding, UI actions, browser automation, and cross-app workflows on macOS and Windows.

Problem

Most AI automations stop at chat or browser-only scripting. Real work often spans native desktop apps, browser tabs, file managers, and system actions.

Solution

ScreenHand provides one tool layer for end-to-end execution:

  • See: screenshots + OCR + accessibility/UI automation tree
  • Act: click, type, scroll, drag, set values, menu actions
  • Automate web: CDP tabs, DOM actions, JavaScript execution, waits
  • Orchestrate workflows: native app + browser steps in one agent loop

Why this matters for developers and teams

  • Faster QA and UI regression checks
  • Practical onboarding/repetitive task automation
  • Better support ops and growth ops workflows
  • Reusable action memory for repeated tasks

How we built it

  • Native bridge layer (Swift on macOS, .NET on Windows)
  • TypeScript MCP runtime and tool orchestration
  • OS APIs: Accessibility/UI Automation, OCR, Chrome DevTools Protocol, AppleScript (macOS)

Technical proof points

  • 25+ automation tools exposed via MCP
  • Fast UI tree operations for element inspection and interaction
  • Cross-platform architecture with one consistent tool interface
