96actions available

Three actions you can hand over today

Every action runs live through MCP. Nothing to build, nothing to maintain.

  • Create customer

    Lyro creates a new customer profile in Square with contact details. Support agents set up customer records without leaving the chat.

  • Cancel invoice

    Lyro cancels a Square invoice to stop payment collection immediately. Agents resolve billing errors without contacting the billing team.

  • Search orders

    Lyro searches for orders across Square locations using various filters. Agents quickly find customer orders to answer questions or process adjustments.

How businesses use Square + Lyro

Each card is one request a support team gets, and the Square actions Lyro runs to close it.

  • Trace a payment back to the customer who made it

    Lyro searches customers by the detail a person gives, lists the payments on the account, and searches the orders behind them, so a charge someone does not recognise is identified from Square's record.

  • Keep the customer record worth searching

    Lyro creates the customer if they are new, adds them to the group that drives their segment or pricing, and writes a custom attribute so the detail survives the conversation.

  • Answer an invoice question and act on it

    Lyro retrieves the invoice in question, lists what else is outstanding for that customer, and cancels one that should never have gone out, so a billing query does not need a second person.

  • Answer a chargeback with evidence attached

    Lyro retrieves the dispute, writes the text evidence describing what happened, attaches the supporting file, and submits it, so a chargeback is contested rather than conceded by default.

How it works

Get started in 3 steps

Connect once, then just ask. There is no workflow builder to learn and nothing to maintain — Lyro reads the Square actions it has and picks the ones a request needs.

  1. 01

    Connect Square

    Authorize the Square account your team already uses — one consent screen, no API keys, no mapping tables. Lyro can only do what you granted that account, and you can disconnect it at any time.

  2. 02

    Tell your agent what you need

    Describe the job the way you would hand it to a teammate. Lyro maps it to the Square actions that close it and chains as many as the request needs.

  3. 03

    Watch it work

    The agent runs the actions inside the conversation the customer is already in, so nobody copies data between tabs and your team can take over at any point.

Everything else about Square

Setup, permissions, and the limits of what Lyro can do inside Square.

  • Not with this toolkit. The payment actions exposed are List Payments and Cancel Payment, with no create-payment or refund action, so Lyro reads and cancels rather than charges. Create Card only stores a card on a customer profile; the card data itself stays in Square.
