Square MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Square and the rest of your systems. It gives your agent 308 Square actions (142 reads, 114 writes and 52 that wait for a confirmation) and holds the Square credential itself, so the agent never does. It paces Square's limits and records every call.

Set up

Connect Square in three steps.

  1. 01

    Add actionlake to Claude.

    Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us.

    https://connect.actionlake.com/mcp
  2. 02

    Connect Square.

    Bearer token. No consent screen: your agent can connect it for you, but the key then passes through your chat. To keep it out of the model's context, paste it in the console instead. actionlake stores what you paste write-only, sealed under your tenant's key.

  3. 03

    Make the first call. Check before a write.

    Ask in plain words; Claude picks the action. Before anything changes, check validates the call and prices it, for free.

Square's own MCP server

Square's MCP server, or actionlake?

Square runs a remote MCP server at mcp.squareup.com, in beta, signed in with OAuth, and a local one that takes an access token.

Use Square's server when one person wants to work in Square from their own AI client. Use actionlake when you also want Square behind the same endpoint as your other systems: a key per agent with allowed actions and a spending cap, a named person's approval before destructive actions, a sealed record of every call, and one ask across Square and another system.

Source: Square's documentation, checked 22 October 2026.

Top actions

The Square API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 204 of Square's 221 action names are shared with at least one other connector, so an agent learns them once.

Governance for Square

Destructive actions wait for a yes.

52 Square actions are destructive. The first 10:

  • Delete Catalog Objectsquare.catalog.delete_catalog_object
  • Batch Delete Catalog Objectssquare.catalog.batch_delete_catalog_objects
  • Pay Ordersquare.orders.pay_order
  • Create Paymentsquare.payments.create_payment
  • Delete Customersquare.customers.delete_customer
  • Bulk Delete Customerssquare.customers.bulk_delete_customers
  • Delete Invoicesquare.invoices.delete_invoice
  • Cancel Invoicesquare.invoices.cancel_invoice
  • Cancel Loyalty Promotionsquare.loyalty.cancel_loyalty_promotion
  • Refund Paymentsquare.refunds.refund_payment

A destructive action runs only with confirm: true. Under the human policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after.

Questions

The Square MCP server, answered.

Is there a Square MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 308 Square actions across customers, bookings, POS and inventory, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Square.

Does Square have its own MCP server?

Square runs a remote MCP server at mcp.squareup.com, in beta, signed in with OAuth, and a local one that takes an access token. (Square's documentation, checked 22 October 2026.) Use Square's server when one person wants to work in Square from their own AI client. Use actionlake when you also want Square behind the same endpoint as your other systems: a key per agent with allowed actions and a spending cap, a named person's approval before destructive actions, a sealed record of every call, and one ask across Square and another system.

What do I need to connect Square?

Square access token. Plus your api host. The free call account { op: "connections.requirements", service: "square" } lists exactly what to paste.

Can an AI agent delete or change things in Square?

Only if its key allows it, and only with an explicit confirmation. 52 Square actions are destructive, including delete Catalog Object, batch Delete Catalog Objects and pay Order. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it.

Will an AI agent use up my Square API limit?

actionlake paces every call to the limits in the Square service file: 100 calls a minute per connection. Repeated reads are answered from cache (141 Square actions can be), which never reaches Square.

What does a Square action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (308 Square actions page). Cache hits, searches, dry runs and calls Square refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Which Square API does it cover?

The Square API 2026-08-19 at connect.squareup.com/v2 by default, or the base URL set when you connect. It is built from Square's documentation as read on 15 September 2026. 308 actions in 24 areas, each one in the signed service file (version 2.0.0).

Does actionlake keep my Square data, and where?

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to an hour, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Square credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.

Which AI clients can use it?

Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
