What McSH is

McSH is a free terminal launcher for Minecraft on Linux and Windows, aimed at managing separate game installations without graphical-launcher overhead. It can create, run, rename, clone, configure, and delete isolated instances. Each instance can keep its own resolution, RAM, JVM arguments, environment variables, and pre- or post-launch hooks. World saves can be zipped manually or automatically before every launch. Modrinth integration handles mods, modpacks, resource packs, shaders, plugins, and data packs, while a built-in catalog helps find modpacks. McSH imports Prism Launcher and MultiMC instances and exports instances as Modrinth packs. It can download and manage a modpack’s required JDK or use a custom Java path. Microsoft Device Code authentication supports token refresh and multiple accounts. Local skin PNGs, account skins, capes, six themes, and English or Spanish translations are included. The maker says it uses under 30 MB of RAM and starts in about one second. Version 1.0.6 downloads are listed at about 35 MB for each platform.
