How it works

• Public catalog scrapes HTML from yandex.ru/games — Yandex Games renders game data server-side in __appData__ JSON and game-card elements. No API key required.

• Console API calls games.yandex.ru/console/api/application* with Session_id cookie and X-CSRF-Token header for authentication.

• Transport: stdio (standard MCP protocol). The server speaks JSON-RPC 2.0.
