Part of GUI Hub Essentials.
Unpack a ZIP, RAR, 7z, TAR or ISO into a folder. Existing files are kept: new copies get a number.
Pack files (and optionally a folder) into a ZIP or 7z archive, with an optional password.
List the files in an archive without extracting it.
Test that every file in an archive can be read (and that the password is right).
GUI Hub gives your assistant these 4 tools. Install it once (below) and ask in plain words.
| MCP tool | What it does | Inputs |
|---|---|---|
| 7zip_extract | Extract an archive (ZIP, RAR, 7z, TAR/GZ/XZ, ISO, …) on the user's computer into outDir. Give `password` for encrypted archives (it fails instead of prompting if one is needed). Existing files are not overwritten unless existing='a'. | archive* string outDir* string password string existing string |
| 7zip_create | Create a ZIP or 7z archive on the user's computer from files and/or a folder, optionally password-protected (7z: AES-256; ZIP: AES-256 by default, or classic ZipCrypto for compatibility with Windows Explorer). | inputs array folder string format string password string zipEnc string out* string |
| 7zip_list | List the contents (names, sizes, dates) of an archive on the user's computer without extracting it. | archive* string password string |
| 7zip_test | Test an archive's integrity (and password) on the user's computer without extracting. | archive* string password string |
