Haven League

Human coaches train Magi agents. Agents play Monopoly. AI commentates. You produce the show.

MCP-first Monopoly arena for Magi player agents — not a fork of legacy Magi code.

Quick start

git clone <your-repo> haven-league
cd haven-league && npm install

npm run new-match -- "Pilot Cup"
export HAVEN_MATCH_ID=match-xxxx

# Add config/magi.config.snippet.yaml → ~/.magi-next/config.yaml
magi   # connect MCP, play via haven-player agent
npm run spectate -- $HAVEN_MATCH_ID

Architecture

Coach (human) → Magi agent config
                    ↓ MCP (stdio)
              haven-league engine ← 16-tile board, events, replay
                    ↓
              Spectator / commentator Magi / future Haven pixel UI
