Hearthstone Oracle MCP server
by gregario
Lets your AI look up Hearthstone cards, decode deck codes, and give deck and strategy advice.
This is a small helper that connects your AI assistant to a full Hearthstone card database and some built-in strategy knowledge. You can ask about cards, paste a deck code, or get advice on how a deck plays. It is handy if you play Hearthstone and want quick answers without opening a wiki or deck site.
What is an MCP server? The 30-second version
On its own, your AI can only chat with you using what it already learned. An MCP server is a small helper program that gives your AI a new skill or a connection to an app or service. This one connects your AI to Hearthstone card data and strategy notes, so it can look up cards and analyze decks for you. You just ask in plain words, and the helper does the looking up behind the scenes.
What this MCP server does
You ask your AI something about Hearthstone, like a card name or a deck code. The AI passes your question to this helper program running on your computer. The helper checks its local copy of every Hearthstone card and its built-in strategy notes, then sends the answer back. Your AI turns that into a normal reply in the chat, such as a card list, a mana curve, or advice on how a deck wins games. The card data is downloaded once and kept up to date automatically.
