Clipboard to Supabase

Clipboard to Supabase MCP Helper is a cross-platform local agent that monitors the system clipboard for images, automatically uploads them to Supabase Storage, and writes the public URL back to the clipboard. Built with Node.js, it supports macOS, Windows, and Linux through platform-specific clipboard access methods, and exposes MCP endpoints for AI assistants to trigger image uploads and manage file retention. The implementation features efficient change detection through hash-based deduplication, automatic cleanup of older files, and can be configured to run at system startup, making it particularly valuable for users who frequently need to share screenshots or images without manual upload steps.
