Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Read Smaregi stores, products, customers, stock and transactions; manage customers, products, stock.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
smaregi_list_storesList the stores (shops) of the Smaregi contract: id, code, name, address, phone. Use the ids to filter stock and transactions. GET /stores.
smaregi_get_storeOne store by id. GET /stores/{store_id}.
smaregi_list_staffsList staff members: id, code, name, role, e-mail. Passwords are never returned. GET /staffs.
smaregi_get_staffOne staff member by id. GET /staffs/{staff_id}.
smaregi_list_categoriesList product categories (departments): id, code, name, parent, level. Use the ids when creating or filtering products. GET /categories.
smaregi_get_categoryOne product category by id. GET /categories/{category_id}.
smaregi_list_productsList products with id, category, code, name, price, cost and update time. Filter by category, code, group code, display flag or update time (a 31-day maximum range). GET /products.
smaregi_get_productOne product by id, optionally with store prices, bundled items, store assignments, reserved stock, attribute items and order settings. GET /products/{product_id}.
smaregi_list_customersList customers (members): id, code, number, name, phone, e-mail, address. Smaregi cannot search by name, phone or e-mail: filter by customer code, member number, id range or update time, or page through. Contains shoppers' personal data. GET /customers.
smaregi_get_customerOne customer by id, optionally with the contract's custom fields. Contains personal data. GET /customers/{customer_id}.
smaregi_list_stockList stock levels per store and product (stockAmount, reserved amount). Filter by store or product. Smaregi only lists a product once its quantity has changed at least once. An update-time filter needs both bounds (31 days at most). GET /stock.
smaregi_list_stock_changesThe stock change history of one product in one store: date, amount, division (sale, purchase, transfer, adjustment...). GET /stock/changes/{product_id}/{store_id}.
smaregi_list_transactionsList sales transactions (receipts) in a time window of at most 31 days: id, date-time, division (1 = normal sale, 2 = deposit, 3 = withdrawal...), store, terminal, customer, totals. Optionally with the line items (limit 100 then). Contains shoppers' personal data. GET /transactio
smaregi_get_transactionOne transaction (receipt) by its transaction id (transactionHeadId), optionally with line items, discounts and payments. Contains personal data. GET /transactions/{transaction_id}.
smaregi_create_customerWRITE: create a customer (member). customerCode, firstName and lastName are required; the contract's own required-column settings may demand more. Not idempotent: calling twice with a different code creates two customers. POST /customers.
smaregi_update_customerWRITE: change fields of one customer (only the fields you pass are changed). Overwrites the old values. PATCH /customers/{customer_id}.
smaregi_create_productWRITE: create a product. categoryId, productName and price are required. Not idempotent. POST /products.
smaregi_update_productWRITE: change fields of one product (only the fields you pass are changed), for example its price or name. Overwrites the old values. PATCH /products/{product_id}.
smaregi_set_stockWRITE: set the absolute stock quantity of one product in one store, replacing the current quantity. Use smaregi_adjust_stock for a relative change. PATCH /stock/{product_id}.
smaregi_adjust_stockWRITE: add (positive) or subtract (negative) a quantity to the stock of one product in one store. Not idempotent: a repeat applies the change again. POST /stock/{product_id}/add.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.12.3) reached the registry yesterday.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

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 the login page asks for your Smaregi credentials.

| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Pro (per account) | $9/mo or $90/yr (2 months free) | Unlimited* |
\*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to support@usefulapi.io.
Pro covers this server only. Subscribe with smaregi_upgrade (it returns a Stripe Checkout link). Cancel any time with smaregi_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running smaregi_upgrade before then undoes the cancel. Or write to support@usefulapi.io.
