A reply by Smarthouse (@localyzapp) on X to a question about the best harness for connecting local models to a Minecraft server. It suggests an MCP server that wraps RCON plus a small agent loop. The main pitfall is block coordinates: expose "/execute if block" as a read tool so the agent can check blocks before placing them, or it will hallucinate terrain.

TL;DR Suggests an RCON-wrapping MCP server and small agent loop for Minecraft agents, with a block-check read tool to prevent hallucinated terrain.
