Card search, rules lookup, deck analysis, and Commander intelligence. Provides 14 tools for AI assistants to answer questions about Magic cards, game rules, combos, synergies, and format meta via the [Model Context Protocol](https://modelcontextprotocol.io). **Not just another Scryfall wrapper.** mtg-oracle downloads card data, comprehensive rules, and combo databases locally into SQLite for fast offline queries, and ships with curated MTG knowledge (archetypes, format primers, commander strategies, mana base guidelines) that makes LLMs genuinely competent at Magic. ## Installation ```bash npm install -g mtg-oracle ``` Or run directly with npx: ```bash npx mtg-oracle ``` ## Claude Desktop Configuration Add to your Claude Desktop config (`~/Library/Application Support/Claude/claude_desktop_config.json` on macOS): ```json { "mcpServers": { "mtg-oracle": { "command": "npx", "args": ["-y", "mtg-oracle"] } } } ``` Or if installed globally: ```json { "mcpServers": { "mtg-oracle": { "command": "mtg-oracle" } } } ``` ## Claude Code Configuration ```bash claude mcp add mtg-oracle -- npx -y mtg-oracle ``` ## Data On first run, mtg-oracle downloads card data from Scryfall and rules data from Academy Ruins.
