README

hearthstone-oracle

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.

Features

Complete card database from HearthstoneJSON — every collectible card, auto-updated
Deck decoding and analysis — paste a deck code, get full card list, mana curve, and archetype breakdown
Strategy knowledge — archetypes, class identities, matchup dynamics, and game concepts
9 MCP tools — search, lookup, decode, analyze, coach

Quick Start

claude mcp add hearthstone-oracle -- npx -y hearthstone-oracle

Card data is downloaded automatically from HearthstoneJSON on first run and stored locally in ~/.hearthstone-oracle/. No API key required.

Claude Desktop

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "hearthstone-oracle": {
      "command": "npx",
      "args": ["-y", "hearthstone-oracle"]
    }
  }
}

Tools

Tool	Description
`search_cards`	Search cards by name, text, class, cost, type, rarity, set, or keyword
`get_card`	Get complete details for a specific card with fuzzy matching
`get_keyword`	Look up keyword/mechanic definitions with related cards
`decode_deck`	Decode a deck code into full card list with mana curve
`analyze_deck`	Analyze a deck's archetype, gameplan, strengths, and matchup profile
`get_archetype`	Learn about deck archetypes (aggro, control, combo, midrange, tempo, value)
`get_class_identity`	Strategic identity of each Hearthstone class
`get_matchup`	Theoretical matchup dynamics between archetypes
`explain_concept`	Fundamental game concepts explained for Hearthstone

How It Works

Two-layer architecture:

Card data layer — Full card database from HearthstoneJSON, stored in a local SQLite database with FTS5 full-text search. Cards are fetched on first run and updated when newer game builds are available.
Strategy layer — Built-in strategy knowledge covering archetypes, class identities, matchup theory, and core game concepts. Enables the server to provide coaching and analysis, not just raw card data.

Data Source

Card data provided by HearthstoneJSON by HearthSim. Auto-extracted from game files. Unrestricted use.
