Your agent plays the game and fixes what breaks.

It plays with input events, reads the live scene tree, the profiler and Godot’s errors, fixes what it finds and plays again.

Saved to assets/Audio/Music

Placeholder music, until yours is ready.

Your agent makes looping tracks in your game’s style, saved into your project, for you to swap for your own.

Making game music with AI

Godot, with the AI you choose.

Flockbay’s own AI, your Claude Code or ChatGPT, any agent over MCP, or 100+ models on a plan or your own key.

Which models you can use

In Flockbay: Connectors › Connect your agent (MCP) › Turn on, pick Claude Code or Codex and press Copy. Paste that line here, then check that flockbay is listed:

PS C:\> claude mcp list
PS C:\> codex mcp list

In Flockbay: Connectors › Connect your agent (MCP) › Turn on writes the line with this Mac’s paths. Paste it in Terminal, then check that flockbay is listed:

% claude mcp list

In Flockbay: Connectors › Connect your agent (MCP) › Turn on, pick Cursor and press Add to Cursor, or Copy and add it to %USERPROFILE%\.cursor\mcp.json. The entry has this shape, with your machine’s paths:

{
  "mcpServers": {
    "flockbay": {
      "command": "<node>",
      "args": [
        "<coordinator>",
        "--external-stage-mcp"
      ],
      "env": {
        "FLOCKBAY_MCP_DESCRIPTOR": "<descriptor>"
      }
    }
  }
}

In Flockbay: Connectors › Connect your agent (MCP) › Turn on, pick VS Code and press Copy. Add it to .vscode/mcp.json in your game folder, or run MCP: Open User Configuration and add it there.

Paste this into Claude Code, Codex or Cursor in your game folder. Your agent checks the connection and reads the project before it changes anything.

Connect Flockbay to this session. Flockbay is installed on this Windows computer and serves Godot tools over MCP.

1. I registered its MCP server with the line the Flockbay app wrote (Connectors › Connect your agent (MCP) › Copy). If it is not registered, ask me to paste that line in a terminal.
2. Check it: `claude mcp list` or `codex mcp list` lists flockbay. If flockbay is listed but the flockbay_status tool is its only tool, ask me to open the Flockbay app with this game and turn on Connect your agent (MCP), then start a new session.
3. Call flockbay_project_info and tell me in a few lines what this Godot project is: its main scene, its autoloads and the scripts that run the main loop.
4. Change nothing yet. Ask me what to work on.

Your own agent, free

Free on your own Claude Code, Codex, Cursor or API key. Flockbay sets no limit of its own; your plan’s limits apply.

How Flockbay sits on Godot

Questions.

What Flockbay is, what it costs, and what it does with your project.

What an AI game maker is

What is Flockbay?
Flockbay is a free AI game maker built on Godot: a desktop app for Windows, macOS and Linux whose AI builds and play-tests a real Godot 4 project inside the full Godot editor, on free AI to start or your own Claude or ChatGPT. The project is an ordinary Godot project on your own disk, on the official engine, not a fork, and the game runs locally. Building needs an internet connection. There is no browser version.
What the AI does
Flockbay's AI, on its free hosted model or your Claude or ChatGPT in the chat, or your own agent over MCP, writes GDScript and scenes into your Godot project. It places props, builds rigged 3D models with the modeler, finds Godot plugins for you to install, and playtests the game: a headless run, stdout and parse errors, viewport capture, input events and the live scene tree. You judge the result by playing it.
Platform
Windows, macOS and Linux: the current release runs on 64-bit Windows with an Intel or AMD processor, on Macs with Apple Silicon, and as an x86_64 Linux AppImage. There is no web version, no browser editor, no browser preview, and no mobile app.
Who writes the code
Your AI does, and you can: it writes the GDScript into a real Godot 4 project, and Flockbay hosts the full Godot editor, Script editor included, beside the chat. You can open, read and change every file there, in stock Godot or in your own code editor.
Where the game runs
Output is a normal Godot project in a normal folder on local disk. Games run locally on the copy of Godot bundled with the app. No streaming, no cloud rendering, no cloud building.
Pricing
Free, AI included. Every account starts with free usage on Flockbay's hosted AI. Or build on your own AI: your Claude plan (Pro or Max) or your ChatGPT account (any plan, Free included) in the app, your own agent over MCP, or your own API key (OpenAI or Anthropic), and you pay the company that runs your model, never Flockbay. Optional plans add more hosted AI: Hobby at $20, Indie Developer at $60 and Studio at $200 a month. There is no team, per-seat, or enterprise plan. Projects and assets are private.
AI models
Free AI runs on Flockbay's hosted model, which Flockbay picks and the model menu names. On your Claude plan, Flockbay runs Claude Code, and the model menu lists the models and effort levels Claude Code gives you. On your ChatGPT plan, it runs your account's models through the bundled Codex engine. On an API key, it runs any model the key reaches, and an agent over MCP uses whatever model that agent runs.

Beautiful games, never slop

We build Flockbay for games worth playing: made with AI, played by people, and polished until they are beautiful. We put that in writing, along with how we will be open about AI in games.
