Xero's official server connects an agent to a Xero organisation for contacts, the chart of accounts, and invoices. It uses Xero OAuth, and the README recommends a demo company before a live one.
“Using the demo company, list unpaid sales invoices and their contact names. Do not create an invoice.”
The README requires Node.js 18 or newer and a Xero developer app. Custom connections, with a client id and secret for one organisation, are the mode it recommends for clients such as Claude Desktop. A second auth mode is also documented in the repo.
The feature list names contacts, chart of accounts, and invoices. It suggests Xero's demo company, which has sample data, for early use. Payroll-specific queries need an NZ or UK organisation. The license is MIT. A real Xero organisation is a paid product, so the cost label is paid account.

MCP server
Stripe's AI repository documents a hosted MCP server at mcp.stripe.com that signs in with OAuth, plus official skills and plugins for several AI apps. The README does not include a tool-by-tool list, so this entry does not invent one.
