What you get

  • Free — ask for cards in plain language with search_cards / get_card. No Scryfall syntax required.
  • Pro — build-around seeds (find_synergies), inventory a list and pull gap fillers (deck_gaps), check format legality (validate_deck).
  • Your AI stays in charge of the brew. The MCP returns cards and deck facts — not canned “search plans” — so you don’t get lost across tens of thousands of names.
  • Responses include ready-to-render markdown card tiles (Scryfall art) instead of raw JSON dumps.
