Onepiece Oracle

Onepiece Oracle is an open-source Model Context Protocol (MCP) server that provides powerful search, analysis, and browsing tools for the One Piece Trading Card Game (TCG). It leverages a community-maintained card database, allowing users to perform full-text card searches with comprehensive filters, browse all card sets and printings, analyze deck lists (cost curve, color, type, counters), and identify defensive cards for building or optimizing decks. Designed primarily for players, collectors, and developers integrating TCG data into apps, it serves as an API backend or tool for TCG analysis and deck building.
