Manage Your Square Payments, Orders, and Invoices Through Your Muse

Through an AnythingMCP custom connector, your muse can run everyday checks on your Square business in plain words: what you took in, what was refunded, what is in stock, and which invoices are unpaid.

What it does

The connector adds 34 tools. The muse can list payments newest first, open one with its tip, fees, and receipt link, and list refunds with reasons. It can search orders across up to ten locations. It can find a customer by email or phone and show their recent orders. It can search your catalog by name or stock level, read an item's stock count at each location, and, after you confirm, update a catalog item. It builds invoices safely: first an open order, then a draft that reaches nobody until you approve it. Three delete tools, for customers, catalog items, and draft invoices, start switched off.

How to use it

1. Start an AnythingMCP account and add the Square connector.
2. Sign in to the Square developer site, create an application, and open its Credentials page.
3. Enter the access token only where the connector asks. Start with the Sandbox token: practice, no real money.
4. Ask the muse to show the token's merchant. It returns your business name, country, and currency, proving the connection works.
5. In Muse, open Settings, then Connectors, and add a custom connector with the address AnythingMCP gives you. Sign in and approve.
6. Start with a read: which payments the main location took yesterday.

What you need

• A Muse account that can add custom connectors
• An AnythingMCP account with the Square connector added
• A Square account and an access token from its developer site

What to watch for

• The token from the Credentials page has full access to your Square account and never expires. Keep it secret. If it leaks, replace it there and update the connector.
• A refund sends money back and cannot be undone, and publishing an invoice emails it to the customer. Before either, the muse states the amount, customer, and record IDs and waits for your yes.
• A catalog update replaces the whole item, so the muse reads it fully first and sends back a complete copy.
• Most records belong to one location. Offline orders can take up to 72 hours to appear. The connector does not take card payments and does not handle gift cards, loyalty, bookings, or payouts. This is a custom connector, and Meta does not review custom connectors. You can disconnect it in Settings at any time. The muse prepares, you decide.
