Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

products
list_products_in_shop
1 つのショップの公開中の商品をすべて返す。価格（JPYC 建て）・在庫・バリエーション・配送要否・対応チェーンを含む。list_shops でショップを見つけたあと、その品揃えを見るのに使う。
search_products
JPYC EC Platform 上の公開商品を横断検索する。減農薬米・地酒・伝統工芸品など、生産者から直接 JPYC で購入できる商品が対象。text は自然言語のキーワード（例: 『丹波 米』）で、商品名と説明に部分一致する。category / tag（産地・認証種別など）、価格帯（min_price / max_price、JPYC）、shop_slug で絞り込める。売上順で最大 50 件返す。
order
get_order_status
ウォレットアドレスの注文履歴を新しい順で返す。x402 で購入した注文は即時に order_status=3（決済完了）となり tx_hash を持つ。
product
get_product
1 つの商品の詳細を product_id で取得する。価格（JPYC 建て）・在庫・SKU・バリエーション・配送要否・対応チェーンを返す。購入の前に必ず呼んで、requires_shipping（配送先が必要か）と has_variants（オプション選択が必要か）を確認すること。
quote
quote_checkout
カートの内容で x402 チェックアウトの 1 回目を実行する。在庫を 5 分間仮押さえし、小計・割引・送料・合計（JPYC）と reservation_id、および署名対象の x402 PAYMENT-REQUIRED チャレンジ（base64url）を返す。エージェントはこのチャレンジを自分のウォレットで EIP-3009 TransferWithAuthorization 署名し、submit_payment に渡す。全 item は同一ショップである必要がある。配送が必要な商品があれば shipping を、贈答なら gift_recipient を必ず渡すこと。
shop
get_shop
1 つのショップ（生産者・職人）の詳細を slug で取得する。ショップのストーリーや説明、対応ブロックチェーン、x402 決済が有効かどうかを返す。
shops
list_shops
JPYC EC Platform に出店している公開ショップの一覧を返す。減農薬の農産物・地酒・伝統工芸品など、生産者から直接買えるショップが中心。各ショップの name / slug / 説明 / 対応チェーン / 商品点数を含む。商品を探す起点として最初に呼ぶとよい。
submit
submit_payment
quote_checkout で得た reservation_id と、エージェントが署名した x402 PaymentPayload（base64url）を渡して決済を確定する。サーバは facilitator 経由で on-chain settle し、確定した注文（order_number / tx_hash）を返す。署名は quote_checkout が返した payment_required の 内容に対する EIP-3009 TransferWithAuthorization であること。

Ec Storefront — questions

Answers built from our own checks of this server.

What can Ec Storefront do?
It exposes 8 tools, read directly from the server on our last check. Among them: get_order_status, get_product, get_shop, list_products_in_shop, list_shops, quote_checkout and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Ec Storefront working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 56 of 91 checks got a reply (61.5%), average response time 410 ms. The bar chart above shows every period we have measured.
The registry lists Ec Storefront as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Ec Storefront?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Ec Storefront need an API key?
No. Ec Storefront completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Ec Storefront?
It answers our handshake in 410 ms on average, which is faster than 32% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
