Payment Gateway
Square MCP connector
The Square connector brings payments, refunds, and orders into Elaichi, so once Square is connected your team can look up a charge, issue a refund, or build an order from Claude, ChatGPT, Cursor, or the Elaichi Agent, each person signed in as themselves.

FAQ
Frequently asked questions
How do I connect Square to Claude?
Connect Square in Elaichi first, then in Claude go to Customize, then Connectors, then Add, and paste https://api.elaichi.ai/mcp as the endpoint. Square requires an OAuth application registered inside Square, so one person on your team creates it in the Square developer dashboard and enters its client ID and secret in Elaichi once. After that, everyone else simply signs in with their own Square login when prompted and never sees those details.
Does Square work with ChatGPT and Cursor as well as Claude?
Yes. Once Square is connected in Elaichi, the same endpoint, https://api.elaichi.ai/mcp, works in Claude, ChatGPT, Cursor, any MCP client, and the Elaichi Agent. You connect Square once and it is available everywhere your team already works.
What can an AI agent actually do with my Square data?
With Square connected, an agent can look up a payment, list the payments and refunds from a given day, create or cancel a payment, issue a refund, and build, price, clone, or pay a Square order. It can also manage the custom fields you attach to orders. Short, specific asks such as "refund payment ending 4421 from Tuesday" work better than long paragraphs.
Does connecting Square give the AI access to every location and every transaction?
No. Everything an agent does in Square runs under the Square permissions of the person who signed in, so it can only see the locations and transactions that person can already see. Elaichi can narrow that further, for example to read-only or to a subset of actions, but it can never grant more than the person already has in Square.
Can I stop an agent from deleting or changing things in Square?
Yes. Restrictions in Elaichi work per action, so you can allow reading Square payments and orders while blocking refunds, cancellations, or edits. A blocked action is never shown to Claude, ChatGPT, or any other client at all, so no prompt, however worded, can reach it.
What happens to a Square connection when someone leaves?
When you offboard a person in Elaichi, their access to Square through every connected client ends immediately. If they connected a shared Square connection, it keeps working for everyone else on the team. If you ever want Square gone entirely, disconnecting it once in Elaichi removes it from Claude, ChatGPT, Cursor, and every other client at the same time.
