MouseKeyProxy.Repl 0.5.5

MouseKeyProxy

Free hotkey-only alternative to PowerToys Mouse Without Borders for exactly two Windows 11 systems.

MouseKeyProxy provides a Windows service, a user-session tray/dashboard agent, and the mkp .NET tool for pairing two machines and transferring keyboard/mouse ownership with an explicit hotkey.

Quick Start

dotnet tool install --global MouseKeyProxy.Repl
mkp --version
mkp --help
mkp service install
mkp pair status
mkp toggle

Default hotkey: Ctrl+Alt+F1.

Features

• Explicit hotkey toggle only; no mirror mode and no edge-of-screen switching.
• Exclusive input forwarding so one machine receives keyboard and mouse at a time.
• Pairing, status, service lifecycle, emergency release, logs, clipboard, and remote-control commands through the canonical mkp CLI/REPL surface.
• User-session dashboard for pairing state, active peer, service state, clipboard state, recent errors, and emergency release.
• Windows Event Log diagnostics.
• LIFO clipboard sync with bounded history and privacy skips.
