Cursor App Tunneling
Cursor on your phone and tablet.
Steer agent chats from anywhere. A Windows PC still runs the AI — CAT Host on the computer, phone or tablet talks over HTTPS.
What CAT is
CAT (Cursor App Tunneling) is a phone and tablet remote for the Cursor IDE on a Windows PC. Open projects stay on the desktop; you approve, prompt, and watch agents from your pocket or a tablet. Your repo stays on the PC. Host runs there; the remote reaches it through CAT over HTTPS.
How it works
- 1
Install CAT Host on each Windows PC
Every computer that runs Cursor needs its own Host. Leave it in the tray. Extra PCs are a later paid tier (Nerd / Institution); unlocked for everyone today.
- 2
Point Cursor at CAT
Shortcut Target: quoted Cursor.exe, then --classic --remote-debugging-port=9222. After a Host or Cursor update, relaunch from the tray so those flags come back.

Sign in on your phone or tablet
When CAT Host is live, tap Connect. No extra VPN or port-forwarding.
