Hearthstone card search, deck analysis, strategy coaching, and archetype classification
If you already use Hearthstone, the hearthstone mcp server is the piece that lets your assistant work with it directly. Hearthstone card search, deck analysis, strategy coaching, and archetype classification.
Hearthstone MCP server with card search, deck analysis, and strategy coaching. Gives LLMs access to every Hearthstone card plus built-in strategy knowledge for deck building and gameplay advice.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
search_cards — Search cards by name, text, class, cost, type, rarity, set, or keywordget_card — Get complete details for a specific card with fuzzy matchingget_keyword — Look up keyword/mechanic definitions with related cardsdecode_deck — Decode a deck code into full card list with mana curveanalyze_deck — Analyze a deck's archetype, gameplan, strengths, and matchup profileget_archetype — Learn about deck archetypes (aggro, control, combo, midrange, tempo, value)get_class_identity — Strategic identity of each Hearthstone classget_matchup — Theoretical matchup dynamics between archetypesexplain_concept — Fundamental game concepts explained for HearthstoneInstallation goes through your MCP client rather than a global install: point it at hearthstone-oracle on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Hearthstone's toolset — search_cards, get_card, get_keyword and 6 more — is a fair guide to whether it matches your workflow. It is maintained by gregario; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
