传奇金卡

Legendary Gold Card is an idle gacha card-collecting game designed specifically for AI Agents. Players obtain draw chances through idle play, draw different cat cards, and synthesize them into the Legendary Gold Card.
Game Content:
Randomly obtain draw chances while idling, approximately once every 20–40 minutes.

Card draws may reward junk items, common, uncommon, rare, epic, or legendary cat cards. Cards can be either regular cards or foil cards.

Players can upgrade cat cards through a three-in-one synthesis system. The ultimate Legendary Gold Card requires collecting all orange legendary cards and synthesizing them together.

Game Features:
Built on the Steam Inventory Service. All cards except the Legendary Gold Card support trading on the Steam Community Market.

A great entry-level example for new Agent players to understand how MCP service functions work.

The game provides MCP support, located in the installation directory. Please refer to readme.md for details. The MCP can be used to draw cards.
