Square makes Squaremates generally available and opens a CLI and MCP for sellers’ own agents

Squaremates is generally available to US sellers at no additional cost. The agent, which Square opened as Managerbot in an open beta on 28 April, now opens as the default landing page in Square Dashboard. Alongside it, the company has launched a Square command-line interface and an updated Model Context Protocol server, so a seller can work with their Square account from an AI assistant they already use. The CLI and MCP are in beta. Squaremates itself isn’t available to sellers on Square’s Multi-Account Suite.

Say hello to Squaremates, the AI partner built for your business. Squaremates is always keeping up with what’s selling, who’s coming back, and what’s running low. And because it’s connected to everything in Square, it can show you what deserves your attention, then take the busywork off your plate.

Squaremates is built into Square, so it works from the sales, payments, inventory, customer, staff and marketing data already in a seller’s account. There’s nothing to export or upload first. Square says each seller’s agent runs in its own workspace with access to cloud compute, which lets it take on jobs that span several steps and more than one part of the business. The examples it gives include finding customers who have lapsed over a stretch of sales and drafting a campaign or discount to bring them back, making bulk catalogue updates to prices, descriptions, channel visibility and images, and weighing labour costs against sales to propose a staffing schedule.

When a task finishes, Squaremates can hand back a finished file, such as a graphical sales breakdown or a designed, on-brand email campaign. Square’s product documentation says the agent asks for approval by default, and that a seller can ask it to handle simpler tasks on its own. Access follows the roles, permissions and locations already set in the account. Owners, managers and staff can use it, and a seller can turn a teammate’s access off in Dashboard Permissions.

It’s available on Square Dashboard on the desktop and in the mobile app. Square’s support documentation says it uses data from the Square account and publicly available information on the web, that it can make mistakes, and that sellers should check responses before acting on them, especially for big decisions. It doesn’t provide financial, tax or legal advice. Many changes can be reversed by asking Squaremates to undo them; a marketing campaign that has already been sent cannot.

Running a business is an endless string of judgment calls that are all on the owner. How to price a new menu item, whether to add a shift, what to do about a slow week. We built Squaremates to help share that load, and now it can take on more of the work than ever before: longer, more complex tasks that used to mean manual reconciliation and hours at a desk, now handled start to finish and handed back as something a seller can actually use.

Fraser Thompson, who leads strategy and operations at Los Angeles restaurant Burgers Never Say Die, is quoted in Square’s announcement describing how he used the agent to look at attachment rates and customer segments for the restaurant’s house-made cheese sauce. He said regulars already loved it, the team started promoting it more openly on social media, and that a few months later “we’d 12x’d our cheese sauce.”

Squaremates is also starting to work outside Square’s own software. A capability still in beta can check what’s running low, prepare an order, and build it on a supplier’s website for the seller to complete. Square says a daily briefing will later be able to pull in a seller’s inbox, with permission, alongside what’s happening in the business.

A CLI and MCP for the agent a seller already uses

Sellers who want to stay in another AI tool can connect a Square account to it through an updated remote MCP server at mcp.squareup.com/mcp, or through the new Square CLI, published as @square/cli on npm, with standalone binaries for macOS, Linux and Windows. Avé said the CLI is in beta. Square’s developer documentation also marks the MCP server as in beta. Square already offered an MCP server; this launch describes the new one as improved.

npm install -g @square/cli

The remote MCP signs in with OAuth and talks to production resources. A local copy can be pointed at a seller’s sandbox, which Square recommends before using the server in production. Square’s agents page lists Claude Code, ChatGPT, Cursor and other MCP clients. It says a seller picks an access level when they connect, that every request runs through Square’s public APIs and the permission checks behind them, and that access can be revoked. The same page says the MCP keeps read-only tools separate from write tools, and that the CLI asks before any delete or cancel.

The CLI signs in through the browser with OAuth and stores credentials in ~/.config/square-cli/credentials.json with file mode 0600. It doesn’t accept access tokens, and it ignores the SQUARE_ACCESS_TOKEN environment variable. Commands cover catalog, orders, payments, customers, inventory and other parts of the public Square API, print JSON by default, and ship a machine-readable command manifest and skill files that can be synced into an agent. Standalone Linux binaries need glibc, so Alpine and other musl-based distributions aren’t supported.

If you already have an AI agent you love, you can now run your Square business from it. The Square CLI and MCP give your agent access to orders, catalog, customers, payments, inventory and more. The CLI is available in beta today.

Custom apps, hosted on Square

Sellers can also build Squaremates Apps: custom applications connected to the business, either by describing what they need to Squaremates or by using the CLI with a coding agent, then deploy and host them on Square. Square’s examples include a cash tip splitter based on timecards, and a live staffing board across locations.

Donnie McClanahan, who runs four cafes around Knoxville, Tennessee, and consults for restaurants through Table & Ledger, is quoted describing an app he built with the CLI and a coding agent. “When you run multiple locations, a lot of the morning used to be playing catch-up just figuring out who’s where and whether every location is covered,” he said. “With the Square CLI and an AI coding agent sitting at my desk, I built a labor board app that pulls my team’s schedules and timecards into one live view across all of my locations. I can see who’s in, who’s working at another cafe, and who’s off, without checking each location separately.”

Square’s support documentation says only account owners and admins can create, manage and view Squaremates Apps. The apps can read and change Square account data in both preview and published versions, and restoring an earlier app version doesn’t reverse changes already made to Square data. The CLI documentation says the apps platform runs in production only, so a production seller account has to be used to sign in first.

Square also plans a Squaremates mobile app built on Buzz, described as a team communication and task management tool where staff can work with AI agents. Sellers can join a waitlist for alpha access.

The CLI, the MCP server and the supplier restocking feature remain in beta, and the Buzz-based mobile app is still on a waitlist. Squaremates itself is generally available to US sellers, except those on the Multi-Account Suite. Squaremates can also answer questions about a seller’s current Square subscription and recommend a paid upgrade when a requested feature isn’t on their plan.
