MTG MCP

A Model Context Protocol server for Magic: The Gathering card data using the Scryfall API.

What it does

This MCP server lets LLMs look up MTG cards and search through them. Pretty straightforward - you ask about a card, it fetches the data from Scryfall.

Why use this?

If you're using Claude or another LLM that supports MCP, this gives it access to the entire MTG card database. This means you can:

• Get help building decks for any format (Standard, Modern, Commander, etc.)
• Analyze and tune your existing decks - find better cards, fix your mana curve
• Calculate the right number of lands for your deck based on your curve
• Look up card interactions and rules text while deck building
• Search for cards that fit specific strategies or combos
• Get deck recommendations based on cards you already own

Basically, it turns your LLM into a deck building assistant that actually knows what cards do.
