MCPersist is a Minecraft mod that extends e4mc's LAN world sharing by allowing worlds to persist as headless servers after the host leaves, maintaining a stable address via relay. It targets casual multiplayer with friends, reducing the need for dedicated servers or port forwarding. The project is in alpha and heavily AI-assisted, but fills a specific gap in the Minecraft modding ecosystem.

Target audience: Minecraft players and server admins
