MTG MCP Servers

MTG MCP Servers is an MCP server suite that connects LLM clients to Magic: The Gathering game mechanics and the Scryfall card database. Written in Swift, the project provides two core components: a deck management engine and a Scryfall API integration server. Magic: The Gathering players, deck builders, and game developers use it to test opening hands, manage game states, review official comprehensive rules, and query card statistics directly from AI assistants. The deck manager handles parsing text-based decklists, drawing cards with shuffling logic, executing London mulligans, and moving cards between mainboards and sideboards. Meanwhile, the Scryfall server provides card information including mana costs, images, legality formats, and text search across the card library. Users can simulate plays, inspect curve statistics, and clarify rule interactions inside conversational environments like Claude Desktop.

How to install and configure MTG MCP Servers

Follow these steps to build and register MTG MCP Servers with Claude Desktop: 1. Ensure you have Swift 6.2 or later and macOS 13 or later installed. 2. Clone the repository and build the release binaries: bash git clone https://github.com/ericraio/mtg-mcp cd mtg-mcp swift build -c release 3. Open your Claude Desktop configuration file (located at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS). 4. Add the built executables to your mcpServers configuration using absolute paths: json { "mcpServers": { "mtg-deck-manager": { "command": "/path/to/mtg-mcp/.build/release/mtg-mcp", "args": ["--transport", "stdio"] }, "scryfall-api": { "command": "/path/to/mtg-mcp/.build/release/scryfall-mcp", "args": ["--transport", "stdio"] } } } 5. Restart Claude Desktop to enable the tools.

What you can do with MTG MCP Servers

• Simulating opening hands: Load a decklist, draw initial card hands, and execute London mulligans to test starting consistency. - Searching Magic cards: Query the Scryfall API using exact names, fuzzy matching, or syntax filters to locate card text and legalities. - Consulting game rules: Look up specific MTG comprehensive rule numbers or search key concepts like priority and the stack. - Testing sideboard plans: Swap cards between your main deck, hand, and sideboard to prepare for specific competitive match-ups. - Analyzing deck statistics: View real-time distributions, card counts, and mana metrics directly through AI conversational prompts.
