GUI Hub
For Claude, Cursor, VS Code & other MCP clients

Can Claude unzip a file or open a RAR?

Not on its own. a chat AI can't run programs or write files on your computer. With the GUI Hub Essentials MCP server installed, Claude (Desktop or Code), Cursor, VS Code and other MCP clients can unzip a ZIP, RAR or 7z file locally: the assistant calls the 7zip_extract tool, which runs 7-Zip on your machine. Files are not uploaded.

Set it up (2 minutes)

  1. Claude Code / Cursor / VS Code / Windsurf: add the MCP server
    npx -y https://guihub.cc/mcp.tgz --product=essentials
    Claude Code: claude mcp add gui-hub-essentials -- npx -y https://guihub.cc/mcp.tgz --product=essentials
  2. Claude Desktop: download the one-file extension and double-click it.
  3. No AI? GUI Hub Essentials is also a point-and-click desktop app.

Then ask

“Unzip the RAR in Downloads into a new folder.”

What the AI gets

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'.

InputType
archive*string
outDir*string
passwordstring
existingstring (u, s, a)

Cost

Free to install; each tool has 3 free uses. Then $9 once for all of GUI Hub Essentials (no subscription). The tool tells the assistant when free uses run out and how to unlock.

Powered by 7-Zip (LGPL-2.1 (+ unRAR restriction)), the official release, verified by SHA-256. GUI Hub is independent and not affiliated with 7-Zip, Anthropic, Cursor or Microsoft.
