Make browser games by chatting with your AI assistant. The assistant writes a Godot 4.8 game; arcadegnt builds it, publishes it at its own web address, and plays it in a real browser on desktop and phone so the assistant sees screenshots and fixes what is wrong.

Connect your assistant

Claude (web and desktop)

1. Open Settings, then Connectors.
2. Choose Add custom connector, name it arcadegnt and paste the URL:

https://arcadegnt.com/mcp

3. Press Connect, enter the code we email you, and choose Allow.
4. Ask: “Make me a one-button arcade game with arcadegnt.”

ChatGPT

1. In a ChatGPT Business or Enterprise/Edu workspace, ask an admin to enable Developer mode for connected data. Pro supports read-only custom MCP apps.
2. Open Settings → Apps → Create, enter arcadegnt and this MCP server URL:

https://arcadegnt.com/mcp

3. Choose OAuth, scan the tools, complete arcadegnt sign-in and consent, then create the app. Start a new chat and select arcadegnt from its tools menu.

ChatGPT labels and availability vary by plan and workspace policy. Full write actions currently require Business or Enterprise/Edu.

Claude Code

claude mcp add --transport http arcadegnt https://arcadegnt.com/mcp

Then run /mcp in Claude Code, pick arcadegnt and sign in.

Codex

codex mcp add arcadegnt --url https://arcadegnt.com/mcp
codex mcp login arcadegnt

The login opens a browser to sign in with your email.

Cursor

Add to ~/.cursor/mcp.json (or the project's .cursor/mcp.json), then sign in when Cursor asks:

{
  "mcpServers": {
    "arcadegnt": {
      "url": "https://arcadegnt.com/mcp"
    }
  }
}

OpenCode

Add to opencode.json in the project (or ~/.config/opencode/opencode.json), then sign in:

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "arcadegnt": {
      "type": "remote",
      "url": "https://arcadegnt.com/mcp"
    }
  }
}

opencode mcp auth arcadegnt

The login opens a browser to sign in with your email.

VS Code

Add to .vscode/mcp.json, start the server from the file and sign in:

{
  "servers": {
    "arcadegnt": {
      "type": "http",
      "url": "https://arcadegnt.com/mcp"
    }
  }
}

Manus

1. Open Settings, then Connectors (in some versions, Integrations).
2. Choose Add connectors, then Custom MCP. Name it arcadegnt, pick the HTTP transport and paste the URL:

https://arcadegnt.com/mcp

3. When Manus asks you to log in, enter the code we email you and choose Allow.

OpenClaw

openclaw mcp add arcadegnt --url https://arcadegnt.com/mcp --transport streamable-http --auth oauth
openclaw mcp login arcadegnt

The login opens a browser to sign in with your email. openclaw mcp doctor arcadegnt --probe confirms the tools load.

Hermes Agent

Add to ~/.hermes/config.yaml; Hermes opens a browser to sign in the first time it connects (/reload-mcp in a running session):

mcp_servers:
  arcadegnt:
    url: "https://arcadegnt.com/mcp"
    auth: oauth

Any other MCP client

Point a client that supports remote servers (Streamable HTTP) with OAuth at the URL; it registers itself and opens the sign-in page. No API key, header or token to paste.

Tools

Tool	What it does
create_game	Start a new game from the arcadegnt starter: a Godot 4.8 project set up for the web (Compatibility renderer, 1280x720 stretched), with keyboard, gamepad and multitouch controls already wired and a tiny playable scene.
list_games	The user's games with their ids, addresses and whether they are live.
get_game	One game with its address and the result of its latest build.
get_guide	How arcadegnt games are built: the starter project, the web rules the build and the browser enforce, touch and gamepad controls, getting high-fidelity art and sound (generators, CC0 packs, code), and how to work with these tools.
list_files	Every file in the game's project with its size.
read_files	The contents of up to 40 project files at once (text files up to 256 KB).
write_files	Create or replace up to 60 files in one call (scripts, scenes, SVG art, project.godot), and optionally delete files.
edit_file	Change part of one file by exact text replacement.
build	Import the project, load every script and scene, run the game headless for a few seconds, export it for the web and publish it at its address.
get_build	The status and errors of a build (the latest one by default).
check_game	Play the game's latest build (its play address) in headless Chrome: on desktop (1280x720, keyboard and mouse) and on a phone held sideways (844x390, touch) by default.
get_check	The result of a check_game that was still running.
submit_to_arcade	Submit the game's latest build and its game page (set_arcade_page) to the Arcade, the public games gallery (arcade.arcadegnt.com and random mode).
set_arcade_page	The game's page in the Arcade (arcade.arcadegnt.com/<slug>): a description for players and up to 6 screenshots chosen from this game's check_game results (by check_id and label, e.g.
remove_from_arcade	Take the game out of the Arcade, drop any pending submission and unlock it: the latest build goes back to its own address and builds publish there again.
get_stats	Plays, players and players' ratings (1-5 stars) for a game (lifetime and the last 14 days, split by where plays started: the Arcade (gallery), random mode (feed) or its own address (direct)), plus its Arcade status (gallery).
get_game_scores	Every high score board of a game (VbgntScores): counted entries best first, one entry per player, top 100, and `held` entries: suspect scores (over the rules in vbgnt_scores.json, no timed run, or far ahead of the board) that only their sender sees until approved.
delete_game_score	Remove one entry (entry_id from get_game_scores, counted or held) from a board, or with no entry_id reset the whole board (needs confirm=true).
approve_game_score	Count a held score (entry_id from get_game_scores `held`): it joins the public board, replacing that player's counted entry when it beats it.
get_asset_upload_link	A page where the user drops their OWN files into the game: art, sprite sheets, music and sound effects, fonts, 2D and 3D models (glTF/GLB, OBJ, FBX), whole folders or.zip asset packs.
import_asset	Download a public https file or.zip asset pack (e.g.
create_asset_upload	For agents that run commands (Claude Code, Codex): a one-hour upload slot for a file on this machine and the curl command that sends it (replace <LOCAL_FILE>).
finish_asset_upload	After uploading a.zip with create_asset_upload: unpack it into assets/.
list_assets	The game's media files with what is known about each: image size and alpha and a sprite-sheet hint, audio length, a 3D model's meshes, rig and animation names and lengths, a font's name; plus recent imports and how much of the 150 MB is used.
view_asset	See a file you cannot open yourself: an image (pixel art scaled up), a font sample, or a 3D model rendered from four sides with Godot's -Z (forward) marked, so you can tell which way it faces and how big it is.
set_game_images	Use an image in the project as the loading screen (splash: PNG/JPG/WebP/SVG, best 1280x720 or larger, shown while the game downloads and starts; the build converts it to PNG), or splash_from_check: a check_game screenshot (e.g.
download_source	A one-hour link to a zip of the Godot project (opens in the Godot 4.8 editor, 4.8-dev7 or newer).
delete_game	Permanently delete a game, its files and its web page.
whoami	The signed-in account's email, its game count and limits.

Plus the resource arcadegnt://guide (the build guide the assistant reads first) and the prompt make_game (describe a game; the assistant builds it and puts it online).
