# 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. Source: https://elaichi.ai/connectors/square/ ## Facts | | | | --- | --- | | Application | Square | | Category | Payment Gateway | | AI tools | 287 | | Authentication | Connects over OAuth | | Needs your own OAuth app | Yes | | MCP endpoint | https://api.elaichi.ai/mcp | | Works with | Claude, ChatGPT, Cursor, any MCP client, and the Elaichi Agent | | Tools advertised by name | No. 287 tools is past the 30-tool threshold, so clients use `search_tools` and `execute_tool` | ## What you can ask once Square is connected - Show Square payments over 500 dollars from last week. - Which Square orders have open refunds right now? - Summarize Square refund totals by location this month. ## Connect Square in Elaichi This happens once for the organization, before any client is involved. 1. Open Connections, choose Add connection, and pick Square. 2. Optionally set Share with, then press Connect. 3. Supply your own Square app, then approve. Square needs an OAuth app you register yourself, so bring its client ID and secret. One person does this once for the organization. Credentials are vaulted and nobody, including the AI, reads them back. The connection becomes a toolbox immediately, so you can curate which Square tools are exposed, rename them, or freeze arguments before anyone points a client at it. ## Connect Square to Claude Endpoint: https://api.elaichi.ai/mcp 1. Open Customize, then Connectors. 2. Press Add. 3. Name it, paste the MCP server URL, then Continue. 4. Sign in and approve. On Team and Enterprise, an Owner adds it once. Everyone else turns it on for themselves. ## Connect Square to ChatGPT Endpoint: https://api.elaichi.ai/mcp 1. Open Plugins, then press the + button. 2. Name it and paste the endpoint into Server URL. 3. Leave Authentication on OAuth, then tick the risk acknowledgement. 4. Press Create, then sign in and approve. Works on the web today. The plugin directory lives at chatgpt.com/plugins. ## Connect Square to Cursor Endpoint: https://api.elaichi.ai/mcp 1. Open `~/.cursor/mcp.json`. 2. Add the endpoint under `mcpServers`. 3. Reload Cursor, then sign in and approve. Set up per machine, so repeat it on each computer you work from. ## Connect Square to any MCP client Endpoint: https://api.elaichi.ai/mcp 1. Add the endpoint as a remote MCP server. 2. Sign in and approve. The Elaichi Agent already has these tools, with nothing to set up. ## What the consent screen decides Only Read is granted by default, which is not enough to call a Square tool. Over MCP there is no trusted place to confirm a write in the moment, so the consent screen is the standing approval rather than a formality. Grant Read and Run tools. Think hard before granting Delete, which reaches into connected apps and cannot be undone. ## What teams do with Square through Elaichi ### Find the charge a customer is asking about Support. A customer emails about a payment they do not recognize. Pull up the Square payment by amount, date, or card details and tell them exactly what it was for. ### Issue a refund without leaving the conversation Support. When a return is approved, create the Square refund against the original payment and note the reason, all in the same thread where you are helping the customer. ### Reconcile yesterday's payments and refunds Finance. List every Square payment and refund for a date range, spot the ones that failed or were canceled, and get a clean picture before closing the books. ### Build and price an order before it is paid Operations. Create a Square order for a phone or catering request, calculate the total with taxes and discounts, and take the payment once the customer confirms. ### Repeat a standing order in one step Operations. Clone last week's Square order for a regular customer, adjust the quantities that changed, and send it through to payment. ### Tag orders with the details you track Leadership. Add custom fields to Square orders, such as event name or sales channel, so every order carries the context your reports need. ## 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 my team share one Square connection? Yes. One person connects Square in Elaichi and shares the connection with a team, and nobody else needs to handle the client ID, secret, or any other credential. Each teammate still signs in as themselves, so the audit log records who issued a refund or changed an order, not just that the shared Square connection did. ### 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. ## All 287 Square tools Every tool below is callable through https://api.elaichi.ai/mcp once Square is connected, subject to the toolbox it is in and the restrictions on the caller. - **List all Square payments** (List).
