Minecraft AI Companion MCP
Early-alpha local Streamable HTTP MCP bridge that gives an AI companion its own Mineflayer-backed player in a Minecraft Java LAN world. It exposes explicit Minecraft action tools through a localhost bearer-token bridge, has been live-tested on Java 1.21.11, and keeps the model subscription outside the server. Public GitHub repository created September 9, 2026.
