Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
제작자가 쓴 설명(영어 원문)
Read sales, products, stock, balance and payouts; create products in Zettle.
이 세 가지는 절대 하나의 점수로 합치지 않아요. 의견, 측정, 인기는 서로 다른 것이니까요.
이 서버는 아직 쉬운 말로 된 요약을 쓰지 못했어요. 아래는 레지스트리에서 읽어 온 사실이에요.
쓰고 있는 AI 앱을 고른 다음 설정을 복사하세요.
필요한 것
어떤 앱을 쓰세요?
위에서 앱을 고르세요. 기억해 두었다가 다음부터는 버튼에 “…에 설치”라고 표시해요.
웹, 데스크톱, 모바일의 Claude에서 쓸 수 있어요:
https://zettle.usefulapi.io/mcp터미널에서 이 명령어를 실행하세요
claude mcp add --transport http zettle https://zettle.usefulapi.io/mcp프로젝트의 .cursor/mcp.json 또는 ~/.cursor/mcp.json에 붙여 넣으세요
{
"mcpServers": {
"zettle": {
"url": "https://zettle.usefulapi.io/mcp"
}
}
}브라우저가 앱을 열지 물어본 다음, 앱이 설정을 보여 주고 확인을 요청해요. 키 값은 비워 두니 직접 입력하세요.
프로젝트의 .vscode/mcp.json에 붙여 넣으세요

}
}

ChatGPT는 인터넷에 있는 서버에만 연결할 수 있어요:
https://zettle.usefulapi.io/mcp메뉴 이름은 요금제나 시기에 따라 조금 다를 수 있어요.
선택한 앱은 이 기기의 쿠키에만 저장돼요. 계정은 필요 없어요.
이 설정은 제작자의 레지스트리 정보로 만들었어요. README와 다르면 README를 따르세요.
도구 이름과 설명은 서버가 2026년 11월 6일에 알려 준 그대로예요. 우리가 아니라 제작자가 쓴 글이고, 일반 텍스트로만 보여 드려요.
zettle_get_accountThe Zettle user and organization this API key belongs to (uuid, organizationUuid). GET oauth.zettle.com/users/self.
zettle_list_purchasesList POS purchases (sales and refunds) with amount, currency, timestamp, products, discounts, payments, refund info and the cashier. Needs READ:PURCHASE. Amounts are in the smallest currency unit. Default window is the last 3 years. Page with next_page_hash (pass it back as last_
zettle_get_purchaseOne purchase (sale or refund) in full by its purchase UUID (the purchaseUUID1 field of zettle_list_purchases; the older short purchaseUUID is deprecated and not accepted): line items, VAT, payments, refund links. Needs READ:PURCHASE. GET /purchase/v2/{purchaseUuid}.
zettle_list_productsList the products in the POS product library with variants (SKU, barcode, price, cost price, VAT), category, online status and ETag. Zettle returns the whole library at once; this tool slices it with limit/offset and filters by name. Needs READ:PRODUCT. Prices are in the smallest
zettle_get_productOne product by UUID with all variants, prices, VAT, category, images and online-store data. Needs READ:PRODUCT. GET /organizations/self/products/{productUuid}.
zettle_list_categoriesList the product categories (uuid, name). Needs READ:PRODUCT. GET /organizations/self/categories/v2.
zettle_get_libraryThe product library together with its discounts (name, amount or percentage), paginated. Returns products, discounts and next_offset (pass it back as offset). Needs READ:PRODUCT. GET /organizations/self/library.
zettle_create_productWRITE: add a new product to the Zettle product library (it appears in the POS and, if enabled, the online store). Not idempotent: calling twice creates two products. Needs READ:PRODUCT and WRITE:PRODUCT. vat_percentage must be one of the VAT rates enabled in the merchant's Zettle
zettle_list_inventoriesList the stock locations (inventories): inventoryUuid, name, type (STORE, SOLD, SUPPLIER, BIN) and which is the default. Use the STORE inventoryUuid with zettle_get_stock. Needs READ:PRODUCT. GET /v3/inventories.
zettle_get_stockStock balances per product variant (balance, low-stock level and alert, last update). With inventory_uuid: that STORE inventory only; without: all stores. Only products with inventory tracking enabled appear. Needs READ:PRODUCT. Page with next_cursor. GET /v3/stock or /v3/stock/{
zettle_get_stock_for_productsStock balances of a few specific products in one inventory (read-only lookup, nothing is changed). Needs READ:PRODUCT. Page with next_cursor (send the same product_uuids again). POST /v3/stock/{inventoryUuid}/products with the product UUIDs.
zettle_get_account_balanceThe merchant's Zettle account balance (totalBalance in the smallest currency unit, currencyId). LIQUID = money available for payout; PRELIMINARY = payments not yet settled. Optional point in time. Needs READ:FINANCE. GET /v2/accounts/{LIQUID|PRELIMINARY}/balance.
zettle_list_account_transactionsTransactions (payments, fees, payouts, adjustments) in the LIQUID or PRELIMINARY account between start and end (end exclusive), with timestamp, amount (smallest currency unit, can be negative), type and originating transaction UUID. Needs READ:FINANCE. Page with next_offset. GET
zettle_get_payout_infoPayout information of the LIQUID account: totalBalance, currencyId, nextPayoutAmount, discountRemaining and payout periodicity. Needs READ:FINANCE. GET /v2/payout-info.

레지스트리에서 이 카테고리의 활성 서버 전체와 비교했어요. 스타는 게시자가 저장소를 소유한 경우에만 세요.
해당하는 기본 점검 3개 중 3개를 통과했어요. 코드는 읽지 않았어요. 키나 토큰을 넣기 전에 서버가 어떤 권한을 요구하는지 확인하고, 꼭 필요한 권한만 있는 키를 쓰세요.
레지스트리에 필수 키가 나와 있지 않아요. 다만 처음 쓸 때 로그인을 요구하는 서버도 있어요.
제작자의 클라우드에서 실행돼요. 설치 없이 인터넷으로 연결하지만, 보내는 내용은 제작자의 서버를 거쳐요.
GitHub 저장소는 마지막으로 – 변경됐고, 최신 버전(1.4.3)은 어제 레지스트리에 올라왔어요.
Claude Desktop, Claude Code, Cursor, VS Code처럼 MCP를 지원하는 앱에서 쓸 수 있어요. URL로 연결되기 때문에, 원격 MCP 서버를 지원하는 앱(예: 개발자 모드의 ChatGPT)에서도 쓸 수 있어요.
같은 카테고리에는: Spec Driven Development, Remote Desktop Commander, dotnet-mcp

Use your Zettle account from Claude, Cursor, or any MCP client. Read sales, refunds, products, stock, balance and payouts, and create products. Hosted, no local install: connect with your own credentials.
Live endpoint: https://zettle.usefulapi.io/mcp · Homepage: https://usefulapi.io
https://zettle.usefulapi.io/mcp.claude mcp add --transport http zettle https://zettle.usefulapi.io/mcp, then run /mcp to log in.{

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and you sign in with your Zettle account.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/zettle/
On first connect you sign in to Zettle and approve access. Only the Zettle account owner can approve it. You can disconnect it any time in Zettle. No keys go in config files.
