# Merchgraph

> A neutral, sourced guide to anime and game merchandise from Japan and around the world: what exists, what it originally cost, and how fans actually get it. Organised by series. Kingdom Hearts, Demon Slayer and One Piece are live. For figures, apparel, accessories, books, music, games and collectibles from Japanese and Western releases, each catalog records official licensing status, the maker's original price by acquisition type, availability, and how each entry was checked.

## What this is
- A curated catalog, not a marketplace: no listings, no transactions, nothing is sold here.
- Each entry links to its primary source (the maker's or official retailer's page, or reliable press such as Famitsu or 4Gamer). Entries are marked verified or not; prices and availability that could only be checked indirectly are labeled as estimates. We aim for accuracy but cannot guarantee it.
- Official licensed merchandise is the core. A few fan-made brands are included on purpose so they can be told apart from official merch; they are clearly labeled "unofficial / fan-made".
- Prices are the maker's original prices (per draw for ichiban-kuji, per capsule for gachapon), not current resale prices. Items released outside Japan keep their original currency and are also shown converted to yen at a fixed rate.
- Not affiliated with, endorsed or sponsored by the rights holders of any series listed (for Kingdom Hearts: Square Enix, Disney; for Demon Slayer: Koyoharu Gotoge, Shueisha, Aniplex, ufotable; for One Piece: Eiichiro Oda, Shueisha, Fuji TV, Toei Animation), or by any maker, shop or marketplace.

## For AI agents (MCP server)
- The same catalog is available as an MCP server that resolves fuzzy product names and listing titles to catalog entries, explains condition terms, and says whether a Japan-only shop needs a shipping-forwarding service.
- MCP endpoint (Streamable HTTP, no auth): https://mcp.merchgraph.app/mcp (the older https://kh-merch-graph.fandex.workers.dev/mcp keeps working)
