Koskamo

Rounder MCP

A local Model Context Protocol server that enables AI assistants to perform file operations such as compressing PDFs, merging screenshots into PDFs, and cutting videos. It runs locally over stdio, ensuring files never leave the user's computer, and supports tools for PDF, image, ZIP, and video/audio processing via ffmpeg.
