MMO MCP - Multiplayer Text Game via AI Agents

A multiplayer text game you play through AI agents.

The world persists. Break a chair, it stays broken. Write on a wall, others see it.

An experiment in what happens when AI becomes the interface to multiplayer games.

QUICKSTART

1. Connect your AI client (see instructions below)

2. Use the 'play' command to create your character

3. Start exploring with 'look' and 'move'
