Xero

Cursor plugin that connects agents to Xero through Xero's official Model Context Protocol server, run locally by Cursor.

Read and write a Xero organisation's accounting and payroll data — invoices, contacts, chart of accounts, payments, quotes, journals, reports, and timesheets.

Install

1. Open Cursor Settings → Plugins.
2. Search for Xero.
3. Click Install, then set the Xero client ID and client secret (below).

Or run /add-plugin xero in chat.

Xero does not publish a hosted MCP endpoint. Its official server runs locally over stdio and authenticates with a Custom Connection — Xero's machine-to-machine OAuth 2.0 flow — so the plugin takes a client ID and secret rather than prompting for browser sign-in.

Before you connect

1. Sign in at developer.xero.com and create an app with the Custom Connection option.
2. Select the scopes up front. Connections created before 2026-04-29 use the bundled scope list; newer ones use the granular list. The server tries the bundled set first and falls back, so you usually do not need to set XERO_SCOPES.
3. Authorize the connection from the email Xero sends, and pick the organisation to connect.
4. Copy the Client ID, generate a Client Secret, and set both in Dashboard → Plugins → Configure.

A Custom Connection is bound to a single Xero organisation and is a paid add-on per organisation. Payroll tools require an NZ or UK organisation.

What agents can do

Category	Capabilities
Accounts & contacts	Chart of accounts, contacts, and contact groups
Sales & purchases	Invoices, quotes, credit notes, and payments
Banking	Bank transactions and manual journals
Items & tracking	Items and tracking categories
Reports	Profit and loss, balance sheet, trial balance, and aged receivables/payables
Payroll	Employees, leave, leave types, and timesheets (NZ and UK organisations)

The server is the source of truth for tool names and schemas.

Notes

• This is a local stdio server, so npx has to be available on the machine running Cursor. It downloads @xeroapi/xero-mcp-server on first run.
• Xero's own FAQ says the server works with any client supporting local stdio servers, and that its testing was done with Claude Desktop and Cursor.
• Tool calls run with the scopes granted to the Custom Connection, against the one organisation it is bound to. To work with several organisations, create a connection per organisation.
• To narrow the surface further, add a space-separated XERO_SCOPES value to the server's env — for example accounting.invoices accounting.contacts accounting.settings.
• xero-mcp by john-zhang-dev is a community package, and JAX is Xero's in-product assistant. Neither is this server.
