From df64010253d59f2de8662fd033091c435321b7be Mon Sep 17 00:00:00 2001 From: unraid Date: Fri, 3 Apr 2026 22:33:00 +0800 Subject: [PATCH] feat: enable Computer Use with Windows support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 1: Replace @ant/computer-use-mcp stub with full implementation (12 files, 6517 lines from reference project). Phase 2-3: Refactor @ant/computer-use-input and @ant/computer-use-swift from single-file to dispatcher + backends/ architecture: - backends/darwin.ts — existing macOS AppleScript (unchanged logic) - backends/win32.ts — new Windows PowerShell (SetCursorPos, SendInput, CopyFromScreen, GetForegroundWindow) Add CHICAGO_MCP to default build features. Verified on Windows x64: mouse control, dual-monitor detection, full-screen screenshot, foreground app info, running process list.
