Yes. Xero publishes an official MCP server in two forms: a local server for any MCP client, and, since October 14, 2026, a hosted Remote MCP endpoint that is generally available and works everywhere Xero does. Xero's hosted Claude connector is also available to Canadian subscribers. Of the accounting and practice platforms a Canadian firm might run, Xero is the one where an agent can be connected this afternoon with nothing more than a Xero login. The limits are real, though: the Claude connector is read-only, and none of it reaches TaxCycle, the Canadian tax software Xero owns.
Status, verified October 2026
The official server is at github.com/XeroAPI/xero-mcp-server. It is a local server that runs over stdio, authenticates with a Xero developer app through OAuth 2.0, and exposes tools over contacts, invoices, bills, payments, bank transactions, accounts, journals, and reports including the trial balance and profit and loss. On October 14, 2026 Xero announced that Remote MCP is generally available: the same server hosted by Xero at api.xero.com/mcp/v1, launched with 39 tools including ones that create contacts, quotes and payments, connected through a standard Xero app with PKCE sign-in, which is why it is available everywhere rather than only in the countries where Custom Connections exist. It is included for apps on Xero's Core tier or above, Starter apps can use it against the demo organisation only, tool calls count as API calls, and the local server keeps working. The Remote MCP documentation carries the scopes and the tool list.
The hosted Claude connector is generally available and Xero's Canadian page for it is at xero.com/ca/ai-in-accounting/claude. It is read-only: an agent in Claude can look up and summarise, and cannot post transactions. Xero's ChatGPT app went live on September 15, 2026, powered by JAX, Xero's own assistant. Underneath all of it is the Xero API on OAuth 2.0.
Xero has owned TaxCycle since December 2021. The MCP server and the connectors cover Xero accounting only. TaxCycle has no MCP server and no public API; see the TaxCycle MCP server page.
Status verified October 2026. We re-check this page quarterly.
What an agent can do with Xero today
For a firm's own practice or for a client's business, an agent connected to the local server or the Remote MCP endpoint can pull the year's profit and loss and balance sheet, list unreconciled bank lines, find the invoices and bills behind a figure, and, through either server, create contacts and draft invoices. Through the hosted Claude connector the same questions can be asked in plain language inside Claude with no setup beyond signing in, read-only.
On a T1 file, Xero matters for self-employed clients and rental owners whose books live there. An agent can pull the calendar-year figures for the T2125 or T776, reconcile them against what the client reported on the intake questionnaire, and flag the categories that need a preparer's attention before anything is keyed into the return. For practice-level client questions, Xero's Ask in Xero HQ covers the firm's client list, but it is a Xero feature rather than a tool an outside agent can call.
Where Armada T1 fits
Armada T1 is the system of record for Canadian T1 intake, with its own MCP server. The same agent that reads a client's Xero books can record the business or rental summary, the vehicle and home-office figures, and the supporting statements as validated section records in the client's Armada T1 file, with the source stored alongside each figure. The file tracks what is still outstanding, and the agent routes each open question as a task to the preparer or to the client. Armada T1 does not calculate or EFILE returns; the completed file is handed off to the CRA-certified tax software your firm already runs, TaxCycle included.
How to check for changes
Watch the Remote MCP documentation for new tools and the AI Toolkit FAQ for write access in the Claude connector, and the TaxCycle news page for any sign that Xero's MCP work is reaching its tax product. For the rest of the Canadian stack, see MCP servers for Canadian tax and accounting software.
