SMP-GPT turns a plain-English server idea into a generated, configured, launch-ready local Minecraft server. Built it in under 10 hours at DDCx. A Fabric mod replaces the Realms entry point with the SMP-GPT flow. An AI Architect proposes plugins and explains its decisions. An Electron dashboard takes over for launch, logs, plugin review, and AI-assisted admin commands.
