Read KiotViet products, customers, invoices, orders and stock; create customers and orders. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the KiotViet connector, then ask in plain words. The AI picks the tools.
For Vietnamese shops and retailers that sell and manage stock with KiotViet.
The AI shows stock on hand and reserved quantities per product and branch, so you can see what is running low where.
The AI lists sales invoices for a date range with totals and payment status, and opens one invoice with its lines and payments.
The AI finds a customer by code, name or phone, shows debt and totals, and lists the latest orders of that customer.
The AI creates a sales order with lines of existing products in a branch, after you confirm the products, quantities and prices.
Changes dataThe AI checks by phone number whether the customer exists, and creates a new customer record when it does not.
Changes dataThe AI lists goods receipts and supplier orders for a period, with suppliers, totals and lines, so you can see what you bought.
The login page asks for your KiotViet Client ID, KiotViet secret (Mã bảo mật) and Shop name (tên gian hàng).
In KiotViet, a shop administrator opens Thiết lập → Cửa hàng → Kết nối API (Settings, Store, API connection), verifies the contract phone number, generates the secret (Mã bảo mật), accepts the terms and ticks access to customer, invoice and order data. Copy the Client ID and secret from there. The shop name is the store name (tên gian hàng) you log in with, for example minhanhshop. They are used only to call the KiotViet API on your behalf; they are never shown to anyone.
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": {
"kiotviet": {
"url": "https://kiotviet.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"kiotviet": {
"type": "http",
"url": "https://kiotviet.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 KiotViet Client ID, KiotViet secret (Mã bảo mật) and Shop name (tên gian hàng). 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 store account | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per store account | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this KiotViet server only. Ask your AI to run kiotviet_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 kiotviet_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 kiotviet_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 KiotViet. The server calls the KiotViet API with your own KiotViet 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 KiotViet Client ID, KiotViet secret (Mã bảo mật) and Shop name (tên gian hàng). See Before you connect for where to find them.
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 KiotViet Client ID, KiotViet secret (Mã bảo mật) and Shop name (tên gian hàng). 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 KiotViet 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 KiotViet.
Yes, if you approve it. 2 of the 29 KiotViet tools can create or change data. The other 27 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 KiotViet server only. Cancel any time: your paid plan then runs to the end of the paid period. Run kiotviet_usage_status to see how many calls you used.
Ask the AI to run kiotviet_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 kiotviet_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 kiotviet_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.
