Mythic Index MCP Server

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"
