Kyvenza 5.0 turns Mac VMs into AI agent workspaces with MCP file, shell and mouse tools
ScholarBackground836 · reddit · 2026-11-15
Kyvenza 5.0, a VM app for Apple Silicon Macs (macOS/Linux/Windows 11 ARM guests), ships a local MCP server (off by default) that lets AI agents do real work inside a VM.
New tools
- uploadfile/downloadfile (16 MB cap), deliberately with no host-path argument so an agent can't be tricked into reading arbitrary disk files
- execshell with background=true for long builds/tests, plus gettaskoutput and canceltask that kills child processes
- waitforvm so agents stop retrying blindly after startvm
- Windows keyboard/mouse control from screenshot pixel coordinates, working even at the sign-in screen and UAC prompts
- clonevm makes a throwaway copy in 1 second with its own MAC, machine ID, ports and SSH key; execshell works 20 seconds after boot
Safety: restore-snapshot/force-stop sit behind the same allow-create/delete switch (tools vanish from tools/list when off), per-endpoint tokens (NAT guests can reach the host's localhost), and startvm auto-snapshots first.
Limits: keyboard/mouse are Windows-only; sendkeys assumes US key positions; Linux shell runs as root via a guest agent; 16 MB file cap.
Tested on Mac mini M4 with Windows 11 ARM and Ubuntu 24.04 guests. $49 one-time with 7-day trial, on the Mac App Store.
