This repository is the public listing for the hosted remote server (README, server.json for the Official MCP Registry). Hosted remote server; source not public.

CARDZ MCP is a hosted, read-only MCP server that brings CardZ Marketcap's graded Pokémon and One Piece card data into any MCP-compatible AI conversation. It exposes three tools over Streamable HTTP — no API key, no account, no login.

What it does

searchcards finds candidate printings by name or collector number, returning language, set and canonical card-page links. getcard returns a single printing's dated PSA 10 reference price, PSA 10 population, market capitalisation (reference price × population), percentage changes, and up to 365 days of daily price history. get_market returns published market-cap rankings for Pokémon, One Piece, or the combined tracked index.

All prices are daily reference observations in USD — not live executable quotes. Null values mean unavailable data; the server never substitutes zeros.

Interactive view in supported hosts

In MCP Apps-capable hosts such as ChatGPT and Claude, each tool renders an interactive in-chat view showing card artwork, a printing selector and price-history controls. Other hosts receive the same structured data alongside card-page links users can open directly.

Data scope and freshness

Current coverage is graded Pokémon and One Piece PSA 10 cards tracked by CardZ Marketcap. Data dates are included in every response and may differ from the time of query. Successful responses may be cached at the Cloudflare edge for 60 seconds; card images may be cached for 24 hours.

Privacy

Public lookup requires no CARDZ.Game account. The tools never request passwords, addresses, payment details or wallet information. Search terms are sent to the CardZ Marketcap public API. The service uses source IP addresses for rate limiting only and does not create player profiles or maintain a query-history database.

What it is not

CARDZ MCP is data only. It provides no trading, buying, pack-opening, auction, shipping or payment functionality.

Features

  1. Three focused tools — search cards, read per-printing metrics, explore market-cap rankings.
  2. Zero authentication — no API key, no account, no login; connect and query immediately.
  3. Interactive in-chat view — MCP Apps-capable hosts (e.g. ChatGPT, Claude) render card artwork, printing selection and price-history controls inline.
  4. Daily PSA 10 reference prices — dated USD observations with up to 365 days of history per printing.
  5. Market-cap rankings — published rankings for Pokémon, One Piece, or the combined tracked index, with effective dates.
  6. Privacy-first — no player profiles, no query-history database, no analytics or browser storage in the interactive view.
  7. Streamable HTTP transport — single URL endpoint, compatible with any MCP client that supports the protocol.
