One Piece TCG MCP server with card search, deck analysis, and set browsing

VerifiedSTDIODesktop only

Overview

AI-generated overview

Lets an assistant search One Piece TCG cards, browse sets and leaders, and analyze deck lists using community card data.

What you can do
Provides read-only tools over a bundled One Piece Trading Card Game dataset of roughly 4,348 cards. Tools include full-text card search with filters for color, type, cost, power, rarity, attribute, character type and set; set browsing with card counts; card version and alternate-art listings; leader browsing by color; deck cost-curve analysis with color, type and counter breakdowns; and counter-card lookup for defensive deck building.
When to use it
Useful for One Piece TCG players and deck builders who want an assistant to look up cards, check printings, or summarize a deck list's cost curve and color spread. Worth adding if you regularly discuss deck construction and want answers grounded in a card database rather than model memory.
Requirements
Runs locally over stdio as an npm package, so Node.js and npx are needed. No accounts, API keys, environment variables or headers are declared. Desktop-only; not available as a web executable.
Before you install
Read-only lookup and analysis tools; no writes, payments or credentials are involved. Card data comes from community-maintained databases, so accuracy and completeness are not guaranteed. It is a fan-made, non-commercial project unaffiliated with the trademark owners.

Installation

In SourceWeft

  1. Open Onepiece Oracle in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients
