Loyverse for AI agents

Loyverse is free point-of-sale software for small retail and hospitality businesses to manage sales, inventory, employees, and customer loyalty from a single register. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

EVERY LOYVERSE CALL, ON THE RECORD
01 · USE CASES

What agents do in Loyverse.

01

Look up an item's stock

Check an item's current inventory details before confirming it is available to sell at the register.

02

Create a sales receipt

Record a new receipt for a completed sale coming from another channel.

03

Approve before deleting an item

Require approval before deleting a catalog item, since it removes it from past receipts and reports.

02 · ACTIONS

58 Loyverse actions, graded by risk.

Every Loyverse action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

await arc0.policies.set('loyverse', {
  read: 'allow',

04 · AUTH AND DATA

How Loyverse connects.

Users add their Loyverse api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

The same Loyverse connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

Loyverse and Arc0, answered.

Q01

Can I use Loyverse with Claude, ChatGPT or Cursor?

Yes. Connect Loyverse to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Loyverse actions you allow.

Q02

How do users connect Loyverse?

Users add their Loyverse api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

Q03

Which Loyverse actions can my agent take?

58 in total: 33 read, 13 write and 12 destructive, such as “create Receipt”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Loyverse?

Yes. Actions like “delete Tax” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call Loyverse too?

Yes. The same Loyverse connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
