CardNexus MCP Server認証済み注目

Search and value 350,000+ cards. Buy, sell and automate your inventory, just by asking.

CardNexus is a trading card marketplace for 20+ games: Pokémon, Magic: The Gathering, One Piece, Yu-Gi-Oh!, Lorcana, Riftbound and more. Connect it to Claude or ChatGPT and your assistant can price, buy and sell cards for you.

What you get

• 350,000+ cards to search and value, with live market prices and price history.
• A real marketplace: live listings with photos from sellers across the US and Europe, right in your chat.
• Whole decklists at the lowest total: paste up to 400 cards and get the cheapest option, the fewest-sellers option, or a balance of both, shipping counted.
• Inventory on autopilot: add cards in plain English, import a CSV, bulk-edit listings, track your collection's value, ship orders and reply to buyers.

Try asking

Buying

• "What's a Near Mint Charizard ex from 151 worth right now?"
• "Find me the cheapest Near Mint Umbreon VMAX alt art that ships to the US."
• "Here's my Commander deck. What's the cheapest way to buy all of it?"
• "How has this card's price moved over the last year?"
• "Make a $40 offer on that listing."

Selling

• "I just opened a booster box. Add these cards to my inventory."
• "What's my collection worth, and how did it change this month?"
• "Take every damaged card in my inventory off sale."
• "Which orders still need to ship? Mark today's as shipped."
• "Tell the buyer of my last order it ships tomorrow."

In Claude and ChatGPT, results show up as cards with images, prices and an Add to cart button, right in the conversation.
