ChatGPT listing Claude connector docs cardchain.ai

Overview

What CardChain AI does

CardChain AI supplies market data on sports and Pokemon trading cards from within ChatGPT. A card is identified either from a photograph or through a search, and the response can include current pricing with a 30 day history along with population figures across the grading companies.

The app also estimates return before a card is sent off for grading, and it can total the value of an entire collection at once. Questions about how a player's season is shifting demand for their cards fall within its scope, and cards listed for sale on the CardChain AI marketplace can be browsed in the same conversation.

Who it is for

A card collector weighing a purchase, a sale, or whether to submit something for grading.

What stands out

Population data across graders and pre-grading return estimates sit alongside straightforward price lookups.

Where CardChain AI is listed

CardChain, Inc. ships this on both marketplaces: CardChain AI is listed in the Claude connectors directory and in the ChatGPT apps directory, under the same publisher domain.

Only 392 of the 3,150 products in this directory are listed in both marketplaces. One MCP server can serve both surfaces; what differs is each platform's listing and review process.

Claude listing

In the Claude connectors directory

CardChain AI publishes 11 tools to Claude. That is a mid-sized surface: 48% of the 1,253 Claude-listed connectors expose fewer.

That is exactly the median for Claude-listed connectors under Entertainment & Media, where 13 publish counts and 11 is the middle of the distribution.

It falls in the 11-20 tools band, which holds 22.5% of the Claude directory.

Measured against the live endpoint

A direct call to the endpoint returned 11 tools, matching the 11 the listing publishes. Probed 2026-08-07.

Tools the server actually returns

  • search_cards
  • get_card_price
  • find_card_for_grading
  • should_i_grade
  • find_card_to_add
  • add_to_portfolio
  • get_portfolio
  • get_population
  • get_player_stats
  • get_cardchain_listings
  • get_capabilities

CardChain AI publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.

Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

Snapshot

CardChain AI is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality.
