CARDZ — Collectibles & TCG

CARDZ

Version 1.1.4 is deployed at https://mcp.cardz.game/mcp. Compatible hosts can display the MCP Apps view. Standard MCP hosts continue to receive the same three tools with matching text and structured results; they do not need to load the interface. Marketplace review and approval are separate.

CARDZ is a brand for collectible cards, trading card games and collectibles. This release's data coverage is Pokémon and One Piece PSA 10 cards.

Public Pokémon and One Piece PSA 10 reference prices, population, daily history and market rankings. Operated by Jackz Intelligent Technology Co., Ltd. in Japan. Contact: alex@jackz.ai.

Connect the Streamable HTTP MCP at https://mcp.cardz.game/mcp with no authentication. This package uses Agent Plugins 1.0 and contains connection metadata only.

Three read-only tools:

  • search_cards: find candidate card printings.
  • get_card: read exact-card metrics and daily history.
  • get_market: read published market rankings.

Results preserve USD, metric dates and unavailable values. Daily reference prices are not executable quotes. This package has no player account or transaction tools.

Examples: “Find the different printings of OP05-119”; “Show the selected card's seven-day history”; “Show the top five One Piece cards by published market cap”.

Directory acceptance is platform-specific. This public repository and a working endpoint do not mean that a marketplace listing has been approved.

English MCP App demonstration uses the official AppBridge reference host connected to production.

Gemini CLI extension

The repository-root gemini-extension.json publishes the same CARDZ service for Gemini CLI. The extension identifier is cardz; its public brand and publisher are CARDZ. The legal operator is Jackz Intelligent Technology Co., Ltd. (株式会社 Jackz Intelligent Technology), Japan. Publisher contact: alex@jackz.ai.

gemini extensions install https://github.com/cardzgame/cardz-marketcap-plugin

The extension uses Streamable HTTP and allows only search_cards, get_card and get_market. It needs no CARDZ account, API key or local server process. It includes no extra prompts, hooks or commands. Gemini CLI controls the presentation of the returned text and structured data.

Official gallery publishing process: the public repository, root manifest and gemini-cli-extension topic allow automatic discovery. Gallery inclusion is tracked separately from this Git release. This package targets the Gemini CLI Extension Gallery; Gemini web and mobile Connected Apps use a separate distribution process.

Dify Marketplace plugin

The Dify plugin source exposes the same three public CARDZ tools through Dify's Python SDK. It uses the formal fixed MCP endpoint, has no credentials or extra capabilities, and returns text and JSON. Its README and privacy policy include the Japanese operator and alex@jackz.ai. Dify Marketplace submission and approval are tracked separately from this source release.
