MCP servers for building games with AI

The tools worth handing your agent before it opens an editor. Install them once and they're there every session.

MULTIPLAYER + HOSTING

antics MCP

One tool call turns a vibe-coded game into a hosted multiplayer link — rooms, live state sync, leaderboards, and deploy in a single deploy_game. No servers, no player accounts.

PLAYTESTING

Chrome DevTools MCP

Your agent opens the game in a real browser — takes screenshots, reads console errors, records performance traces — then fixes what it actually saw instead of what it guessed. The fastest debug loop for canvas games.

BROWSER AUTOMATION

Playwright MCP

Scripted playthroughs: click, type, and assert through the whole game loop. Open two pages at once and you've got an automated two-player test of your multiplayer flow — join, sync, score, win screen.

3D ASSETS

Blender MCP

Ask for models, materials, and scenes in plain language, then export them into your Three.js game. Turns “I can't art” from a blocker into a prompt.

Connect antics, then just ask for a game.

“Make a 2-player game and deploy it” — the agent calls deploy_game and returns a playable URL. Free to start, no account needed.
