Hearthstone Oracle
Connects Claude to the complete Hearthstone card database via HearthstoneJSON with nine tools for search, deck analysis, and strategy coaching. You can search cards by any attribute (class, cost, keywords, card text), decode deck codes into full lists with mana curves, and get archetype analysis with matchup theory. The server maintains a local SQLite database with FTS5 search and includes built-in strategy knowledge covering class identities, archetypes like aggro and control, and core game concepts. Reach for this when you need Claude to build decks, evaluate card synergies, or provide gameplay advice without manually copying card databases or explaining Hearthstone mechanics yourself. No API key required since it pulls directly from HearthstoneJSON and caches locally.
