What it can do
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.
twicecommerce_get_merchantGet the merchant account: name, country, currency, timezone, languages, plan and enabled features. Good first call. Admin API: GET /v1/admin/merchant.

twicecommerce_list_tagsList tags used on inventory, catalog, customers or orders. Admin API: GET /v1/admin/tags.
twicecommerce_list_ordersList orders with status, customers, line items, totals and dates. The API does not paginate this list, so the result is cut to `limit` rows (newest as returned by the API); the full count is in totalCount. Narrow it with location_ids. Admin API: GET /v1/admin/orders.
twicecommerce_get_orderGet one order by id: status, customers, line items, stock items, comments, totals and pricing. Admin API: GET /v1/admin/orders/{orderId}.

twicecommerce_list_discount_codesList discount codes with usage and validity, with paging. Admin API: GET /v1/admin/discount-codes.

Common questions
Is Twice Commerce MCP by usefulapi safe?
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.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
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.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.5.3) reached the registry yesterday.
Which apps can use it?
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.
What can I use instead?
In the same category: Spree Commerce: open-source B2B and marketplace ecommerce, Stripe MCP, MCP Cn Commerce

Twice Commerce MCP by usefulapi
Use your Twice Commerce account from Claude, Cursor, or any MCP client. Read orders, customers, catalog items, stock, locations and availability, and add comments to orders. Hosted, no local install: connect with your own credentials.
Live endpoint: https://twice-commerce.usefulapi.io/mcp · Homepage: https://usefulapi.io
Connect
- Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste
https://twice-commerce.usefulapi.io/mcp. - Claude Code:
claude mcp add --transport http twice-commerce https://twice-commerce.usefulapi.io/mcp, then run/mcpto log in. - VS Code: Add to VS Code.
- Cursor and other clients: add the URL as a remote MCP server:
{
"mcpServers": { "twice-commerce": { "url": "https://twice-commerce.usefulapi.io/mcp" } } }
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 Twice Commerce credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/twice-commerce/
On first connect you provide a TWICE Commerce API key (TWICE admin → Settings → Integrations & API → Create key; choose Limited access and give Read to the areas you need). The server validates it and stores it per user. No keys go in config files.
