Manage Square merchants, locations, customers, catalog, orders, payments, refunds, and invoices

The Square integration provides access to manage Square merchants, locations, customers, catalog, orders, payments, refunds, and invoices through the Integrate MCP server.

Installation

The Square integration is included with the SDK:

import { squareIntegration } from "integrate-sdk/server";

Setup

1. Create a Square OAuth App

Create an OAuth application for Square
Configure your redirect URI
Note your Client ID and Client Secret

2. Configure the Integration on Your Server

Add the Square integration to your server configuration. The integration automatically reads SQUARE_CLIENT_ID and SQUARE_CLIENT_SECRET from your environment variables:

import { createMCPServer, squareIntegration } from "integrate-sdk/server";

export const { client: serverClient } = createMCPServer({
  apiKey: process.env.INTEGRATE_API_KEY,
  integrations: [
    squareIntegration({
      scopes: ["MERCHANT_PROFILE_READ", "PAYMENTS_READ", "PAYMENTS_WRITE", "CUSTOMERS_READ", "CUSTOMERS_WRITE", "ORDERS_READ", "ORDERS_WRITE", "ITEMS_READ", "ITEMS_WRITE", "INVOICES_READ", "INVOICES_WRITE"], // Optional
    }),
  ],
});

You can override the environment variables by passing explicit values:

squareIntegration({
  clientId: process.env.CUSTOM_SQUARE_ID,
  clientSecret: process.env.CUSTOM_SQUARE_SECRET,
      scopes: ["MERCHANT_PROFILE_READ", "PAYMENTS_READ", "PAYMENTS_WRITE", "CUSTOMERS_READ", "CUSTOMERS_WRITE", "ORDERS_READ", "ORDERS_WRITE", "ITEMS_READ", "ITEMS_WRITE", "INVOICES_READ", "INVOICES_WRITE"], // Optional
});

3. Client-Side Usage

The default client automatically includes all integrations. You can use it directly:

import { client } from "integrate-sdk";

await client.authorize("square");
const result = await client.square.getMerchant({});

console.log(result);

If you're using a custom client, add the integration to the integrations array:

import { createMCPClient, squareIntegration } from "integrate-sdk";

const customClient = createMCPClient({
  integrations: [squareIntegration()],
});
