Connects Claude to blankfiles.com's catalog of minimal valid blank files across dozens of formats. You get tools to list all available file types, filter by category (documents, media, archives, etc.), and retrieve direct CDN download URLs for each format. Useful when you need to generate test fixtures, stub out upload flows, or quickly grab a valid-but-empty PDF, XLSX, MP4, or ZIP without hunting one down manually. The server pulls from a live JSON catalog that includes metadata like MIME types and file sizes, so Claude can recommend the right blank file for your testing scenario and hand you a working URL in one shot.
Laravel application that powers blankfiles.com. Browse and download minimal valid blank files by type and category. File data and assets are served from the filearchitect/blank-files repository via a configurable CDN.
git clone https://github.com/filearchitect/blankfiles-website.git
cd blankfiles-website
composer install
cp .env.example .env
php artisan key:generate
Set CDN_URL in .env (see Configuration). Then build the frontend and run the app:
npm install && npm run build
php artisan serve
Or use Laravel Herd with a .test domain.
