Xero MCP Server

This is a Model Context Protocol (MCP) server implementation for Xero. It provides a bridge between the MCP protocol and Xero's API, allowing for standardized access to Xero's accounting and business features.

Features

Xero OAuth2 authentication with custom connections
Contact management
Chart of Accounts management
Invoice creation and management
MCP protocol compliance

Prerequisites

Node.js (v18 or higher)
npm or pnpm
A Xero developer account with API credentials

Setup

Create a Xero Account

If you don't already have a Xero account and organisation already, can create one by signing up here using the free trial.

We recommend using a Demo Company to start with because it comes with some pre-loaded sample data. Once you are logged in, switch to it by using the top left-hand dropdown and selecting "Demo Company". You can reset the data on a Demo Company, or change the country, at any time by using the top left-hand dropdown and navigating to My Xero.

NOTE: To use Payroll-specific queries, the region should be either NZ or UK.

Authentication

There are 2 modes of authentication supported in the Xero MCP server:

1. Custom Connections

This is a better choice for testing and development which allows you to specify client id and secrets for a specific organisation. It is also the recommended approach if you are integrating this into 3rd party MCP clients such as Claude Desktop.

Configuring your Xero Developer account

Set up a Custom Connection following these instructions: https://developer.xero.com/documentation/guides/oauth2/custom-connections/

Currently the following scopes are required for all sessions: scopes

Integrating the MCP server with Claude Desktop

To add the MCP server to Claude go to Settings > Developer > Edit config and add the following to your claude_desktop_config.json file:

{
  "mcpServers": {
    "xero": {
      "command": "npx",
      "args": ["-y", "@xeroapi/xero-mcp-server@latest"],
      "env": {
        "XERO_CLIENT_ID": "your_client_id_here",
        "XERO_CLIENT_SECRET": "your_client_secret_here"
      }
    }
  }
}

NOTE: If you are using Node Version Manager "command": "npx" section change it to be the full path to the executable, ie: your_home_directory/.nvm/versions/node/v22.14.0/bin/npx on Mac / Linux or "your_home_directory\\.nvm\\versions\\node\\v22.14.0\\bin\\npx" on Windows

2. Bearer Token

This is 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. In this case, use the following configuration:

{
  "mcpServers": {
    "xero": {
      "command": "npx",
      "args": ["-y", "@xeroapi/xero-mcp-server@latest"],
      "env": {
        "XERO_CLIENT_BEARER_TOKEN": "your_bearer_token"
      }
    }
  }
}

NOTE: The XERO_CLIENT_BEARER_TOKEN will take precedence over the XERO_CLIENT_ID if defined.
