# Mythic Index MCP Server

<!-- mcp-name: io.github.wizkid17/mythic-index-mcp -->

Magic: The Gathering card prices, deck analysis, and investment intelligence — powered by live data from 5 vendors covering 99K+ cards.

Connect this MCP server to Claude Desktop, Claude Code, or any MCP-compatible AI assistant to get real-time MTG card pricing, deck cost analysis, sealed product EV calculations, and investment insights.

## What You Can Do

**Ask about prices:**
> "What's the current price of Sheoldred, the Apocalypse?"

**Build decks on a budget:**
> "Find me black creatures with deathtouch under $5 legal in Modern"

**Price a full decklist:**
> "Price this deck: 4 Lightning Bolt, 4 Goblin Guide, 20 Mountain — check Modern legality"

**Evaluate sealed products:**
> "Is the Modern Horizons 3 Collector Booster Box worth buying at $280?"

**Track investments:**
> "What cards spiked this week? Show me Reserved List cards under $50"

**Understand strategy:**
> "What role does Counterspell play? Find me blue counter spells for Commander under $3"

## Quick Start

### Prerequisites

- Python 3.10+ (the MCP SDK requires 3.10 or newer)
- Claude Desktop, Claude Code, or any MCP-compatible client

### Install

The published package runs with no manual install via [`uv`](https://docs.astral.sh/uv/):

```bash
uvx mythic-index-mcp
```

Or install from source:

```bash
git clone https://github.com/wizkid17/mythic-index-mcp.git
cd mythic-index-mcp
pip install -r requirements.txt

### Configure Claude Desktop

Edit your Claude Desktop config file:

**macOS:** `~/Library/Application Support/Claude/claude_desktop_config.json`

      "command": "uvx",
      "args": ["mythic-index-mcp"],
      "env": {
