Query Loyverse POS receipts, shifts, items, inventory and customers, and update stock and customers. Hosted by usefulapi — connect from Claude, ChatGPT, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"loyverse": {
"url": "https://loyverse.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"loyverse": {
"type": "http",
"url": "https://loyverse.usefulapi.io/mcp"
}
}
}No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run these commands. The second one opens the login page:
Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see Before you connect.
The login page asks for your Loyverse personal access token.
Create one in the Loyverse Back Office → Integrations → Access tokens → Add access token. Works on every Loyverse plan, including free. Your token is used only to call the API on your behalf and to derive a private account id; it is never shown to anyone.
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 Loyverse personal access token. 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.
Turn on the Loyverse connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
loyverse_get_merchant | read | Get the merchant Fetch the merchant account this token belongs to — business name, email, country and currency. A cheap way to confirm the token works. Loyverse: GET /merchant/. |
loyverse_list_stores | read | List stores List the merchant's stores (locations) with their addresses. Store ids are what the receipt, shift and inventory filters take. Loyverse: GET /stores. |
loyverse_list_employees | read | List employees List employees, with the stores each can access and whether they are the owner. Loyverse: GET /employees. |
loyverse_list_receipts | read | List receipts List sales and refund receipts, newest first, with line items, payments, discounts and taxes. Filter by store, time range or receipt numbers — the core of any sales question. Loyverse: GET /receipts. |
loyverse_get_receipt | read | Get one receipt Fetch a single receipt by its receipt number (e.g. 2-1008), with line items, modifiers, discounts, taxes and payments. Loyverse: GET /receipts/{receipt_number}. |
loyverse_list_shifts | read | List shifts List cash-register shifts with their cash, gross/net sales, refunds, discounts, taxes, per-payment-type totals and pay-in/pay-out movements — the end-of-day view. Loyverse: GET /shifts. |
loyverse_list_items | read | List items List catalog items with their variants (SKU, barcode, price, cost, per-store pricing), category, taxes and modifiers. Loyverse: GET /items. |
loyverse_get_item | read | Get one item Fetch a single catalog item by id, with its variants. Loyverse: GET /items/{item_id}. |
loyverse_list_variants | read | List item variants List item variants — the sellable SKUs — optionally for given items or one SKU. Variant ids are what inventory levels are keyed on. Loyverse: GET /variants. |
loyverse_list_categories | read | List categories List item categories. Loyverse: GET /categories. |
loyverse_list_inventory | read | List inventory levels List current stock (`in_stock`) per variant per store. Filter by stores and/or variants — the answer to 'what is running low?'. Loyverse: GET /inventory. |
loyverse_list_customers | read | List customers List loyalty customers, newest first, with visits, total spent and points balance. Filter by email or ids. Loyverse: GET /customers. |
loyverse_get_customer | read | Get one customer Fetch a single customer by id, with visits, total spent and points balance. Loyverse: GET /customers/{customer_id}. |
loyverse_list_payment_types | read | List payment types List the payment types (cash, card, integrated terminals…) and the stores where each is available. Receipt payments reference these ids. Loyverse: GET /payment_types. |
loyverse_list_discounts | read | List discounts List configured discounts (fixed/variable percent or amount, discount-by-points) and where they apply. Loyverse: GET /discounts. |
loyverse_list_taxes | read | List taxes List taxes with their rate, whether they are INCLUDED in or ADDED to the price, and the stores they apply in. Loyverse: GET /taxes. |
loyverse_list_suppliers | read | List suppliers List suppliers with their contact details. Loyverse: GET /suppliers/. |
loyverse_upsert_customer | write | Create or update a customer Create a loyalty customer, or update one by passing its `id`. Loyverse does not document whether omitted fields survive an update, so on update fetch the customer first and send the full record. Loyverse: POST /customers. |
loyverse_upsert_category | write | Create or update a category Create an item category, or rename/recolor one by passing its `id`. Loyverse: POST /categories. |
loyverse_upsert_supplier | write | Create or update a supplier Create a supplier, or update one by passing its `id`. Loyverse does not document whether omitted fields survive an update, so on update send the full record. Loyverse: POST /suppliers/. |
loyverse_set_inventory_levels | write | Set inventory levels Set the ABSOLUTE stock (`stock_after`) of one or more variants at given stores — e.g. after a stock count. This overwrites the current level rather than adding to it; read the current levels with loyverse_list_inventory first so they can be restored. Loyverse: POST /inventory. |
loyverse_usage_status | Usage status (free-tier meter) Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter. | |
loyverse_request_feature | Request a missing feature Tell usefulapi that the user needs something the Loyverse tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter. | |
loyverse_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on Loyverse (the free tier caps monthly usage). Plans: "monthly" — $9/month; "yearly" — $90/year (2 months free). Cancel any time: Pro then runs to the end of the paid period, so it also suits a one-time job. *A fair use limit applies. For heavy use (near Pro's limit): "plus" or "plus_yearly" — Pro+, $19/month or $190/year, unlimited tool calls (fair use limit: 100,000 a month); an existing Pro subscription changes to Pro+ in place (needs confirm: true; the price difference for the rest of the period is charged at once). Otherwise returns a short link to open in your browser (it opens Stripe Checkout); after payment the account upgrades automatically. Does not count against the meter. | |
loyverse_cancel_subscription | Cancel the Pro subscription Cancel the caller's Loyverse Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run loyverse_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | Unlimited* |
*Pro fair use limit: 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this Loyverse server only. Subscribe with loyverse_upgrade (it returns a Stripe Checkout link). Cancel any time with loyverse_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running loyverse_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 Loyverse. The server calls the Loyverse API with your own Loyverse 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 Loyverse personal access token. 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 Loyverse personal access token. 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 Loyverse 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 Loyverse.
Yes, if you approve it. 4 of the 21 Loyverse tools can create or change data. The other 17 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 unlimited tool calls (fair use limit: 10,000 tool calls a month), for this Loyverse server only. Cancel any time: Pro then runs to the end of the paid period. Run loyverse_usage_status to see how many calls you used.
Ask the AI to run loyverse_upgrade: it returns a Stripe Checkout link. To cancel, run loyverse_cancel_subscription. Pro continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with loyverse_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.
