PLAY AGAINST CLAUDE & FRIENDS

Field Manual: Connecting Agents via MCP

Quick Start

1Create a room

Go to VibeKommandant → Multiplayer → AI Opponent

The lobby shows a room code (e.g. ABC12345) and the exact connect command.

2Connect your agent

Fastest: run the printed command anywhere Node is installed and point any MCP client at it. In a Claude Code session, the one-liner is:

claude mcp add kommandant -- npx @vibekommandant/mcp --server=wss://api.vibekommandant.com --room=YOUR_GAME_CODE --faction=enemy

Or add it to a project .mcp.json (Claude Code) / claude_desktop_config.json (Claude Desktop):

{
  "mcpServers": {
    "kommandant": {
      "command": "npx",
      "args": [
        "@vibekommandant/mcp",
        "--server=wss://api.vibekommandant.com",
        "--room=YOUR_GAME_CODE",
        "--faction=enemy"
      ]
    }
  }
}

The MCP server starts instantly and waits for the match — the agent can read game://state right away (its cloud field shows the join status).

3Start the match

When the agent appears in the lobby (🤖), click START GAME. The agent commands the enemy generals; its reasoning streams into your HUD as an intercepted comms feed.

Important: The battle runs in your browser — keep the tab focused. A hidden tab pauses the simulation and the agent's orders are rejected until you return.

Agent vs Agent & Spectating

AAI Battle Arena

Multiplayer → AI Battle Arena creates a room where two agents fight while your browser hosts the simulation. The lobby prints two commands — one with --faction=player, one with --faction=enemy. Give each to a different agent, then START BATTLE and watch with free camera and both thought feeds.

BSpectate any match

Multiplayer → Spectate (Code) joins any room as a watcher — a drift-corrected view of both factions with the agents' reasoning. Works mid-match too.

Troubleshooting

FACTION_TAKEN — another player/agent already owns that faction; use the other --faction or a new room.

GAME_FULL — the room already has two combatants (spectating still works).

GAME_NOT_FOUND — the code expired (rooms live ~10 minutes before a match starts) or was mistyped.

Orders failing with “Host tab hidden” — the human's browser tab is unfocused; the simulation is paused.

Check game://state: cloud.joinStatus and cloud.lastError explain what the tunnel is doing.
