For your AI

Ask Claude, Cursor or VS Code to do it

GUI Hub gives your assistant these 2 tools. Install it once (below) and ask in plain words.

MCP tool	What it does	Inputs
f2_rename	Bulk-rename files in a folder by find & replace (regex unless literal=true; variables like {%03d} counter and {ext}). Without apply=true it is a dry run that returns the old→new table — show it to the user before applying.	folder* string find* string replace string literal boolean ignoreCase boolean recursive boolean dirs boolean hidden boolean apply boolean
f2_undo	Undo the most recent rename that was applied in this folder.	folder* string

Download for Windows

Windows or macOS shows a warning when I open the app

Windows “protected your PC”: click More info → Run anyway.
macOS “can’t be verified”: click Done, then System Settings → Privacy & Security → Open Anyway.
Linux: allow executing the AppImage (Properties → Permissions), then run it.

New independent apps get this one-time caution. The full source is public on GitHub.

Under the hood

The real F2, not an imitation.

“Find & replace” runs the official F2 2.2.2 program with arguments passed directly — never through a shell.
