tcgmcp MCP server

Which MCP servers are tcgmcp's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry namecom.tcgmcp/tcgmcpverified in the MCP registry

The registry name sits under tcgmcp.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: Estimate the market value of a full decklist; Check the market price of a single card; Connect an AI assistant to look up card prices.
  • Checked on 2 of the 7 days it takes to judge reliability.

Once connected

  • For "Estimate the market value of a full decklist", the likely first call is price_deck.
  • For "Check the market price of a single card", the likely first call is price_card.
  • For "Connect an AI assistant to look up card prices", the likely first call is price_card.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • price_deck

    Prices a pasted decklist (any TCG: Magic, Pokemon, Yu-Gi-Oh, One Piece, Lorcana, and 18+ more) and returns a ready-to-buy TCGplayer cart link. Paste the raw decklist text — one card per line, quantity + name, e.g. '4x Lightning Bolt' or…

  • price_card

    Looks up the current market price of a single TCG card (any of 22+ games: Magic, Pokemon, Yu-Gi-Oh, One Piece, Lorcana, and more). Returns the best match's price and an affiliate-wrapped TCGplayer product link, plus alternates when the…

  • list_printings

    Lists every known printing of a TCG card (any of 22+ games) — every set it was printed in, with per-finish (nonfoil/foil) prices and treatment tags (border, frame, promo, full art). Use this instead of price_card when the buyer wants to…

  • market_index

    Shows the cross-market price trend for a whole game or a single set — a chain-linked index (base 100) with 7/30/90-day movement, the total market value of one-of-every product, the median price, and how many products are priced. Use this…

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "tcgmcp": {
      "type": "http",
      "url": "https://mcp.tcgmcp.com/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http tcgmcp https://mcp.tcgmcp.com/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://mcp.tcgmcp.com/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
