Read orders, customers, catalog, stock and availability; add order comments in Twice Commerce. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the Twice Commerce connector, then ask in plain words. The AI picks the tools.
For rental, subscription and resale shops that run their orders and stock in Twice Commerce.
List orders and narrow them by pickup location. Open one order to read its customers, line items and totals.
Check the availability of a catalog item for a date window before you create an order.
Search customers by name or email. Read the contact data and the orders of the customer.
Read the payment transactions and the invoices of one order. The API key needs the Payments area.
List the stock items of one location with SKU, condition and status.
Add an internal comment to an order. The API key needs Write access to Order details.
Changes dataThe login page asks for your TWICE Commerce API key.
Create it in the TWICE admin under Settings → Integrations & API → Create key. Pick Limited access and give Read to the areas you want to ask about (Orders, Customers, Catalog, Inventory, Locations). Add Write on Order details only if you want to add order comments. The key is used only to call the API for you and to derive a private account id.
Team and Enterprise: an Owner adds the connector for the organization first.
No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"twice-commerce": {
"url": "https://twice-commerce.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"twice-commerce": {
"type": "http",
"url": "https://twice-commerce.usefulapi.io/mcp"
}
}
} Run these commands. The second one opens the login page:
Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.
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: the login page asks for your TWICE Commerce API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per user | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this Twice Commerce server only. Ask your AI to run twicecommerce_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with twicecommerce_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with twicecommerce_upgrade before then undoes the cancel. Or write to [email protected].

No. usefulapi is an independent service. It is not affiliated with or endorsed by Twice Commerce. The server calls the Twice Commerce API with your own Twice Commerce access, so it sees only the data that your account can see.
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
The login page asks for your TWICE Commerce API key. See Before you connect for where to find it.
No. 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: the login page asks for your TWICE Commerce API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Twice Commerce API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Twice Commerce.
Yes, if you approve it. 1 of the 20 Twice Commerce tools can create or change data. The other 19 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Twice Commerce server only. Cancel any time: your paid plan then runs to the end of the paid period. Run twicecommerce_usage_status to see how many calls you used.
Ask the AI to run twicecommerce_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run twicecommerce_cancel_subscription. Your paid plan continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with twicecommerce_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
