An MCP server is a small service that stands in front of a business system and offers it to an AI chat as a fixed list of tools. Atso is one of these: it gives a business one MCP connection that lets the AI chats their team already uses, such as Claude, ChatGPT and Gemini, read their business software across every account and organisation they own, with control over who can see and change what.
The question worth asking about your own software is narrow: does the company that sells it publish an MCP server. A vendor’s own server is the one that gets first access to their API, moves when the API moves, and is supported by the people who built it. Everything below is about first-party servers, checked on 14 September 2026, and that date is part of the claim. This field moves quickly.
Which vendors ship an MCP server, and which ship nothing?
Among the systems small and mid-sized businesses in New Zealand and Australia actually run on, Shopify publishes several and Xero one, Capsule has one in private beta, and four more, Infusion, Unleashed, Cin7 and MYOB, publish nothing at all. MYOB is in this list because businesses run on it; it is not one of the seven Atso connects, and the four named at the end of this post are the four of those seven, which is a different set.
| System | Does the vendor ship an MCP server | Shape of it |
|---|---|---|
| Shopify | Yes, several | Mostly hosted, built for shoppers and app developers, none for merchant data |
| Xero | Yes | Self-hosted, you run it |
| Capsule | Yes, private beta | Higher plan, by request, two AI clients |
| MYOB | No | Nothing from MYOB |
| Infusion | No | Nothing from Infusion |
| Unleashed | No | Nothing from Unleashed |
| Cin7 Core and Cin7 Omni | No | Nothing from Cin7 |
Three honest notes on that table. A “yes” does not mean the server does the job you want: Shopify’s are the clearest case, and the next section is about why. Servers built by other companies exist for several of these systems, with their own terms and trade-offs, and this post takes no view on them. And a “no” is a statement about one day. Any of these vendors could ship next month.
Does a vendor’s MCP server do the job I need?
Not always, and Shopify is the example worth knowing. It publishes more first-party MCP servers than any other vendor on this list, most of them hosted with nothing to install, and none of them answers a merchant’s question about their own store.
They are built for the two audiences that are not the merchant. Shoppers and the agents buying on their behalf: the storefront server exists to “Connect to a store’s catalog, cart, and policies to help customers shop with that merchant”, and a customer accounts server to “Help customers track orders, manage returns, and access their account information”. And developers: the Dev MCP server, for people writing Shopify apps, “runs locally and doesn’t require authentication”.
That is a serious commitment, and the hosted ones are exactly the right shape. A merchant asking which products sold best last quarter across three stores is asking an admin question, and none of what Shopify publishes is built to answer it.
So “does my vendor ship an MCP server” is really two questions. Does one exist, and does it reach the data you want. A yes to the first with a no to the second is the most confusing answer to land on, because every directory will tell you that you are covered. Shopify is the clearest case of it, and it is worth checking for before you assume either way.
Does my accounting system’s vendor ship one?
Xero does, MYOB does not, and the difference matters less than it first sounds, because Xero’s is a developer tool rather than a product you can simply switch on.
Xero publishes an official MCP server at XeroAPI/xero-mcp-server. That is a genuine
commitment and worth crediting. What it asks of you is the subject of the next section.
MYOB publishes nothing. There was no native Claude connector for MYOB as of April 2026, and a search of MYOB’s own developer material on 14 September 2026 turned up no MCP server from MYOB.
Why does an official MCP server sometimes still not help me?
Because “official” covers two very different shapes. Some vendors host the server and give you an address. Others publish a repository you run yourself, started by your AI client on your own computer, with credentials you create in a developer portal. Xero’s is the second kind.
Xero’s server is set up by adding an npx command to claude_desktop_config.json. Before
that works you create an app in the Xero developer portal and set up a Custom Connection,
which Xero describes as “a better choice for testing and development which allows you to
specify client id and secrets for a specific organisation”. A business with four Xero
organisations is looking at four of those.
There is a second mode, and it deserves saying plainly rather than leaving out. Xero also supports a bearer token, which it calls “a better choice if you are to support multiple Xero accounts at runtime and allow the MCP client to execute an auth flow (such as PKCE) as required”. Multiple accounts are possible. What the sentence does not mention is that something still has to perform that flow and keep a valid token for every account, and that something is you.
Either way, the server runs where you started it. In the stdio transport, “The client launches the MCP server as a subprocess”, so it lives on one machine, stops when that machine does, and keeps its credentials in a file on it. The wider set of limits this creates applies to every self-hosted server, not only Xero’s.
For a developer this is a short evening. For an operations lead it is a wall.
Is a private beta the same as having an MCP server?
No. Capsule announced one on 26 June 2026, and on the day of the announcement it was a private beta, on the Growth plan and above, for two AI clients, granted by request.
Capsule’s own wording sets the conditions: “You’ll need to be on a Growth plan or above to access the Capsule MCP beta”, and “Currently, the Capsule MCP integration works with Claude and Cursor”. Access comes by logging into Capsule, opening Integrations, searching for “Capsule MCP Server” and clicking Request early access.
That is a real product step, and more than most vendors in this list have done. It is also four conditions between an announcement and a working connection. When you read that a vendor has shipped an MCP server, the questions worth asking are which plan, which AI clients, read or write, and whether there is a public address.
Why is my inventory system hard to get a straight answer about?
Partly because two different products share most of a name. Unleashed Software is an inventory and manufacturing system used by wholesalers in New Zealand and Australia. Unleash, without the d, is an unrelated feature-flag product for software teams, and it does publish an MCP server. A search for one will surface the other, so check which company a result belongs to before drawing a conclusion.
On the vendor question the answer is clean: Unleashed Software publishes no MCP server of its own, checked on 14 September 2026.
Infusion has the opposite problem, too little written about it rather than too much. It is a New Zealand accounting and business management system used by trade, wholesale and job-based businesses, and its own site carries no developer MCP documentation at all. We built the connector Atso uses, which is a post of its own.
What can you do when your vendor ships nothing?
Five options, and they suit different people.
- Wait for the vendor. Free, and reasonable if your system is large enough to be on somebody’s roadmap. Ask their support team whether MCP is planned. The answer is useful either way.
- Ask for the beta. Where one exists, as with Capsule, the request costs a few minutes.
- Run a server yourself. Workable if you have a developer. It means the server lives on one machine, and somebody owns keeping it alive.
- Use a server built by another company. For several of the systems above this is the only option that exists today. Terms, hosting and how current the data is vary a great deal, so read those three things before you commit.
- Use a hosted MCP service. One address, several accounts, nothing installed on your machine. This is the category Atso is in, and the honest caveat is that it only helps if the connection you need has been built.
Which connections has Atso built, and which are still missing?
Seven platforms were connectable on 14 September 2026, and eight more appear in the catalogue as coming soon with no date attached to any of them.
Read from Atso’s own atso_list_connectors tool on 14 September 2026, the connectable
platforms were Xero, Shopify, Infusion, Unleashed, Google Search Console, Capsule, and Cin7
in both its Core and Omni forms. Every one of them reads and none of them writes. For
Infusion that is enforced in code rather than by convention, because Infusion has no test or
demo company, so every request goes against a real client’s live books, and the HTTP client
is built so it can only send a GET.
The same tool listed eight platforms as coming soon: MYOB, QuickBooks, Stripe, HubSpot, Mailchimp, WooCommerce, Pipedrive and Klaviyo. Coming soon means listed in the catalogue and not connectable. No date is promised for any of them, and a date from anyone in this market is worth treating with suspicion.
Four of those seven, Infusion, Unleashed, Cin7 and Google Search Console, have no MCP server from their vendor. Google is the one to be careful about, because it publishes MCP servers for other products and none for this one: “There’s no official Google Search Console MCP server”, checked on 14 September 2026.
Of the three that do publish something, none of Shopify’s reach a merchant’s own data and Capsule’s is a private beta, which leaves Xero as the one system on this list where a business could reasonably use the vendor’s own server today. Building the other six is the part of this work worth doing.
