What you can do with Loyverse in Claude and ChatGPT

For shop and cafe owners who run their point of sale with Loyverse.

Sum up sales receipts by store and period

The AI lists sales and refund receipts filtered by store or time range, reads line items, payments and discounts, and totals the sales.

Review the cash register shifts

The AI lists shifts with cash, gross and net sales, refunds, discounts, per-payment-type totals and pay-in and pay-out movements.

Find items that are running low

The AI lists the current stock per variant per store and matches it with the catalog items, SKUs and prices.

Set the stock of items after a count

The AI sets the exact stock of variants at stores. This overwrites the old level, so it first reads the current levels.

Changes data

Look up loyalty customers or add and update one

The AI lists loyalty customers with visits, total spent and points, and reads one customer. It can create a customer or update an existing one.

Changes data

Add or update item categories and suppliers

The AI lists categories and suppliers, creates new ones, or renames and changes existing ones by id.

How do I connect Loyverse?

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.

Claude claude.ai · Desktop

  1. Open Customize → Connectors, then click + Add → Add custom connector.
  2. Enter the name Loyverse and this URL, then click Add:
    https://loyverse.usefulapi.io/mcp
  3. Claude opens the login page: enter your Loyverse personal access token.
  4. In a chat, click + → Connectors and turn on Loyverse.

Team and Enterprise: an Owner adds the connector for the organization first.

ChatGPT chatgpt.com

  1. Open Plugins, click +, then Add custom MCP server.
  2. Enter the name Loyverse and this URL, choose OAuth as the authentication, confirm the warning and create it:
    https://loyverse.usefulapi.io/mcp
  3. ChatGPT opens the login page: enter your Loyverse personal access token.
  4. In Plugins, install Loyverse, then choose it in a chat.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http loyverse https://loyverse.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "loyverse": {
      "url": "https://loyverse.usefulapi.io/mcp"
    }
  }
}

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "loyverse": {
      "type": "http",
      "url": "https://loyverse.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add loyverse --url https://loyverse.usefulapi.io/mcp
codex mcp login loyverse

Other clients

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.

https://loyverse.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: 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.

Pricing

PlanPriceLimit
Free$050 tool calls / month
Proper user$9/mo · $90/yr10,000 tool calls / month
Pro+per user$39/mo · $390/yr100,000 tool calls / month

Each paid plan covers this Loyverse server only. Ask your AI to run loyverse_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 loyverse_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 loyverse_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

  • Create or update a customerloyverse_upsert_customer

    Create an item category, or rename/recolor one by passing its `id`.
  • Create or update a supplierloyverse_upsert_supplier

Your usefulapi plan · 4

  • Usage status (free-tier meter)loyverse_usage_status
    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.
  • Request a missing featureloyverse_request_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.
  • Upgrade to Pro or Pro+loyverse_upgrade
    Get a paid plan for Loyverse (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter.
  • Cancel the Pro subscriptionloyverse_cancel_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.

FAQ

What can I do with Loyverse in Claude or ChatGPT?

Sum up sales receipts by store and period. Review the cash register shifts. Find items that are running low. Set the stock of items after a count. Look up loyalty customers or add and update one. Add or update item categories and suppliers. See what you can do for the details.

Is this an official Loyverse product?

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.

Can I connect Loyverse to Claude or ChatGPT?

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.

What do I need to connect?

The login page asks for your Loyverse personal access token. See Before you connect for where to find it.

Do I put my Loyverse key or an Authorization header in the client config?

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.

How do you keep my Loyverse credentials?

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.

Can the AI change my Loyverse data?

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.

What does it cost?

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 Loyverse server only. Cancel any time: your paid plan then runs to the end of the paid period. Run loyverse_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run loyverse_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 loyverse_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Loyverse tool that I need is missing?

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.

Which AI clients can I use?

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.
