# Your Square sales. Read in one answer. Source: https://corespeed.io/integrations/square Connect Square to Claude Code, Codex, Cursor or any MCP agent through CoreSpeed. Your agent searches orders, reads payments and refunds, and works with customers, catalog items and draft invoices in your own Square seller account. It cannot take a payment or issue a refund, and publishing an invoice is a separate call that approvals can hold. ## Set up an agent Give your agent this line: `set up https://corespeed.io/SKILL.md (read it raw, e.g. with curl)` It fetches the skill at https://corespeed.io/SKILL.md, adds the CoreSpeed MCP server, signs you in (or up), and keeps the skill for next time. Connect Square after setup. Access follows the connected account and its permissions. Create an account: https://app.corespeed.io/sign-up ## Know how the day went. Without the export Ask your agent for a location's orders, sales and refunds, and get a short summary you can share. You ask your agent: "Summarize yesterday's orders at our Valencia Street location: the total, the best sellers, and any refunds. Change nothing." It calls CoreSpeed: - `square__list_locations`: ok, 296 ms - `square__search_orders`: ok, 577 ms - `square__list_refunds`: ok, 341 ms It reads from: Square. ### Daily sales: Valencia Street, yesterday. 38 orders brought in $2,914. One cold brew was refunded. **Best sellers** - Oat latte, 41 sold. - Almond croissant, 27 sold. **Refunds** - One order, $18: a cold brew made wrong. _Illustrative location · No order, invoice or customer changed_ All connectors: https://corespeed.io/docs/connectors ## From the counter to a clear summary Requests you can make once Square is connected.

No. Your agent can read payments and refunds, but the Square connection cannot create either. ### Does publishing an invoice send it? Yes. Publishing makes Square act on the invoice, usually by emailing it. It is a separate call from the draft, and approvals can hold it. How approvals work: https://corespeed.io/docs/approvals ### Which Square account does my agent use? The seller account you authorize with Square's own sign-in. Your agent sees the locations, orders and customers that account can see. ### Do I have to switch agents? No. CoreSpeed adds tools to the agent you already use: Claude Code, Codex, Cursor, or another MCP client. Each one signs in once. ### Can my agent access every account in our organization? No. Access follows your CoreSpeed identity, each connection's visibility, and the app's own permissions. Personal connections stay private. ### Does this work without connecting an account? No. Connect the app's account first; your CoreSpeed workspace shows what each app needs. The examples on this page use fictional data.
