klyo games — MCP server for publishing HTML5 browser games

Publish and manage an HTML5 browser game straight from your AI assistant — Claude, ChatGPT, Cursor, VS Code, opencode or any MCP client. Upload a ZIP or point at a game that already runs somewhere else; the game gets its own address g-<name>.klyo.pl, live stats and a place in the klyo games catalogue. You keep the rights, with no exclusivity.

This repository documents the hosted server. There is nothing to install or run.

Server

URL (games)	https://panel.klyo.pl/mcp?profil=gry
URL (full klyo server: games, websites, hosting)	https://panel.klyo.pl/mcp
Transport	Streamable HTTP
Auth	OAuth 2.1 with dynamic client registration — no API key to paste
Official MCP Registry	pl.klyo/games

Account

There is no separate sign-up. The first time your assistant connects, it opens the klyo login page; signing in with Google or with a one-time email link creates the account on the spot. Publishing needs one step that cannot be automated: accepting the developer terms once, in a browser.

Connect

Claude (claude.ai, desktop, mobile) — Settings → Customize → Connectors → + → Add custom connector → paste the URL → Add (leave Client ID and Secret empty) → sign in → Allow. The connector then appears on your phone as well.

Claude Code

claude mcp add --transport http klyo "https://panel.klyo.pl/mcp?profil=gry"

ChatGPT — needs a paid plan (Plus, Pro, Team, Business, Enterprise or Edu) and Developer mode: Settings → Apps & Connectors → Advanced → Developer mode → Create → paste the URL → finish signing in in the pop-up.

Cursor — ~/.cursor/mcp.json:

{
  "mcpServers": {
    "klyo": { "type": "http", "url": "https://panel.klyo.pl/mcp?profil=gry" }
  }
}

VS Code — .vscode/mcp.json (then click Auth above the server entry):

{
  "servers": {
    "klyo": { "type": "http", "url": "https://panel.klyo.pl/mcp?profil=gry" }
  }
}

opencode — opencode.json:

{
  "mcp": {
    "klyo": { "type": "remote", "url": "https://panel.klyo.pl/mcp?profil=gry", "enabled": true }
  }
}

Each of these clients opens the sign-in page itself the first time a klyo tool is used — there is no key to put in the file.

Then just say: "publish this game on klyo, the package is in this folder".

Tools

The list below is taken from the live server (tools/list), not written by hand. Every tool requires signing in; without a token the server returns 401.

What is live and what is not

• Publishing is free and immediate. After the automatic check you play your own game in a preview and release it to the catalogue with one click. A person from klyo looks at it after that.
• Revenue share: 70% of the net ad revenue attributed to your game, payout threshold 100 PLN. It starts the day Google AdSense approves the portal — as of today no ads are shown and nothing has been paid out yet.
• Leaderboards receive scores from the game itself over a signed round, never typed in. A score made offline waits on the device and arrives when the connection returns.

Po polsku

Serwer MCP klyo games pozwala wydać grę HTML5 prosto z asystenta AI: wgrywasz ZIP albo wskazujesz działającą grę, a ona dostaje własny adres g-<nazwa>.klyo.pl, statystyki na żywo i miejsce w katalogu. Konta nie zakładasz osobno — pierwsze logowanie (Google albo link z maila) tworzy je samo. Dokumentacja po polsku: https://games.klyo.pl/pl/mcp/
