KH Merch Graph MCP Server

Identify a Kingdom Hearts item from a marketplace listing (Mercari, Yahoo! Auctions, Suruga-ya, Mandarake, eBay…). Paste the listing title as-is (Japanese or English), e.g. {title: "一番くじ キングダムハーツ A賞 ソラ フィギュア 箱なし", price_jpy: 4500}. Returns candidates[] (sku_id, name_en, confidence 0-1, why, source_url; several when the title is ambiguous), weak_matches[] when unsure, conditions[] (Japanese condition words such as 未使用/箱なし explained), flags[] (bootleg caution notes, not a verdict), price (original price and listing-to-original ratio when price_jpy is given), shipping (whether a shipping-forwarding service is needed from abroad; set platform for a precise answer; for Mercari/Suruga-ya a note that Mercari's global app may allow direct purchase in some countries), acquisition notes and next_checks_en (what to ask the seller). Listing text is not stored. For many listings at once use resolve_listings_batch.

Run resolve_listing on up to 5 listings in one call, e.g. when comparing search results from a marketplace. Example: {listings: [{title: "…", price_jpy: 3000}, {title: "…"}]}. Returns an array in the same order; each element has the same shape as a resolve_listing result (or {error} for that one listing only). For more than 5, split into several calls. For a single listing use resolve_listing.

Browse the merchandise catalog of one series (Kingdom Hearts) by character, budget and purpose. Use it to answer "what merch exists for X?" or "gift ideas under ¥5,000". Example: {ip: "kingdom-hearts", character: "Sora", budget_jpy: 5000, purpose: "display"}. Returns items[] (sku_id, name_en/name_ja, official, original price msrp_jpy plus price_local/currency, price_basis, region, availability_hint, typical_channels, source_url) and total_matches. If a character has no solo merch (e.g. Xigbar), the result also has suggested_character_group and suggested_items for their group (e.g. Organization XIII). Lists catalog entries only; it does not mean anything is for sale right now. Use explain_product with a sku_id for full details.

Estimate the total cost of buying an item in Japan and having it forwarded abroad. Example: {price_jpy: 4500, sku_id: "ichiban-kuji-kh-2018-a", dest_country: "US"}. Returns routes[] (forwarding service × shipping method, with fees and total_jpy, cheapest first) and cheapest. Rough figures only: fee and shipping tables currently cover US, GB, DE and FR (other countries return no routes), come from third-party comparison guides (mid-2026) and exclude duties. Not a quote; we are not affiliated with any forwarding service.

Get the full record for one catalog item (Kingdom Hearts). Pass a sku_id from discover/resolve_listing (e.g. {sku_id: "ichiban-kuji-kh-2018-a"}), or a free-text query such as {query: "Sora Bring Arts Halloween Town"} to get the best match. Returns names (en/ja), product line (maker, line type, release date), characters, original price (msrp_jpy, price_local, currency, price_basis), acquisition_type (retail, kuji, prize, …), availability (hint + confidence), typical_channels, shipping (whether it is only sold at shops that ship within Japan, so a shipping-forwarding service is needed from abroad; costs are not calculated; for Mercari/Suruga-ya items a note that Mercari's global app may allow direct purchase in some countries), size/weight, re-release dates, official (licensed or fan-made), verified (checked against the source) and source_url.

Report a mistake or missing item in the catalog (reviewed by hand before anything changes). Example: {sku_id: "ichiban-kuji-kh-2018-a", field: "msrp_jpy", proposed_value: "750", source_url: "https://…"}. Please include a primary source (maker, official shop or reliable press) when you can. Returns {accepted, correction_id}.
