## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 46/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 6 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 406, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 66/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1571 tokens (~261/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 43/100
  - Stability observed for 13 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (6)

### `resolve_listing` (~349 tokens)

Resolve listing

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), 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.

Input parameters:

- `description` (string): Part of the listing description, e.g. condition notes such as 開封済み. Optional; improves condition and bootleg checks.
- `platform` (string): Where it is listed. Optional.
- `price_jpy` (number): Listing price in Japanese yen. Optional; enables the comparison with the original price.
- `src` (string): Traffic-source tag for usage statistics, used by the website (optional; only the tag and time are logged). Agents can omit it.
- `title` (string, required): The listing title, copied as-is (required).
- `url` (string): Listing URL. Optional; not stored and not fetched.

### `resolve_listings_batch` (~134 tokens)

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.

Input parameters:

- `listings` (array, required): Listings to check (1–5); each takes the same arguments as resolve_listing.

### `explain_product` (~259 tokens)

Explain product

Get the full record for one Kingdom Hearts catalog item. 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), size/weight, re-release dates, official (licensed or fan-made), verified (checked against the source) and source_url.

Input parameters:

- `query` (string): Free-text product name in English or Japanese when you have no sku_id, e.g. "一番くじ キングダムハーツ A賞".
- `sku_id` (string): Catalog SKU ID, e.g. "ichiban-kuji-kh-2018-a". Either sku_id or query is required.

### `discover` (~367 tokens)

Discover

Browse the Kingdom Hearts merchandise catalog 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.

Input parameters:

- `budget_jpy` (number): Maximum original price in Japanese yen (overseas items are compared at a fixed rate), e.g. 5000. Optional.
- `character` (string): Character name in English or Japanese, e.g. "Sora", "ソラ", "Organization XIII". Partial match. Optional.
- `ip` (string, required): Franchise ID. Currently only "kingdom-hearts".
- `limit` (number): Maximum number of items to return (default 10). total_matches always gives the full count.
- `purpose` (string): "display" = figures, plush, prizes, acrylic stands; "wear" = apparel; "read" = books; "play" = games and cards; "any" (default).
- `terms` (object): Filter by series vocabulary (factions, worlds, keyblades, songs…) found in item names, aliases or notes. Optional.

### `estimate_landed_cost` (~252 tokens)

Estimate landed cost

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.

Input parameters:

- `dest_country` (string, required): Destination country as an ISO 3166-1 alpha-2 code, e.g. "US", "GB", "AU".
- `price_jpy` (number, required): Item price in Japanese yen (required).
- `proxy` (string): Only show one forwarding service, e.g. "buyee". Optional.
- `sku_id` (string): Catalog sku_id, used to look up the weight. Optional.
- `weight_g` (number): Package weight in grams, when there is no sku_id or the catalog has no weight.

### `report_correction` (~210 tokens)

Report correction

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}.

Input parameters:

- `field` (string, required): What is wrong, as a catalog field name, e.g. "name_en", "msrp_jpy", "availability_hint", "official", or "new_item".
- `note` (string): Anything else worth knowing. Optional.
- `proposed_value` (string, required): The correct value (or, for a new item, its name and details).
- `sku_id` (string): The item's sku_id. Leave empty to suggest a new item.
- `source_url` (string): URL of a primary source that confirms it. Optional but strongly preferred.
