Overview

Description from the maker (original English)

Hearthstone card search, deck analysis, strategy coaching, and archetype classification

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Search & AI memory

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

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

Run this in your terminal

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

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

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

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "hearthstone-oracle": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "hearthstone-oracle"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Hearthstone Oracle safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

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

ToolDescription
search_cardsSearch cards by name, text, class, cost, type, rarity, set, or keyword
get_cardGet complete details for a specific card with fuzzy matching
get_keywordLook up keyword/mechanic definitions with related cards
decode_deckDecode a deck code into full card list with mana curve
analyze_deckAnalyze a deck's archetype, gameplan, strengths, and matchup profile
get_archetypeLearn about deck archetypes (aggro, control, combo, midrange, tempo, value)
get_class_identityStrategic identity of each Hearthstone class
get_matchupTheoretical matchup dynamics between archetypes
explain_conceptFundamental game concepts explained for Hearthstone

How It Works

Two-layer architecture:

  1. 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.
  2. 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.
