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"

Scored across 21 tools
All tools have clearly distinct purposes. Search tools differ by query type (fuzzy name, complex filters, browsing, role-based). Analysis tools (mana curve, deck pricing, card evaluation) are distinct. Pricing, legality, rules, sealed, and market tools are also well-separated.
Most tools follow a verb_noun pattern (e.g., analyze_mana_curve, get_card_price). A few deviate (reserved_list_tracker, top_movers) but are still understandable. No mixed conventions like camelCase, so overall consistent.
21 tools cover a broad MTG domain: card searching, pricing, deck analysis, rules, sealed products, market data. Each tool serves a clear need without redundancy. The count is well-scoped for a comprehensive index server.
The tool set covers all major aspects: card discovery (multiple methods), pricing and history, deck building (curve, budget swaps), legality, rules, sealed product EV, and market opportunities. No obvious gaps for the intended functionality.
