Xero MCP Server

Model Context Protocol (MCP) server for the Xero Accounting API. Enables Claude and other MCP-compatible clients to manage Xero contacts, invoices, payments, accounts, and reports.

Quick Start

Prerequisites

• Node.js >= 20
• Xero OAuth2 app credentials (requires a Xero developer account)

Install and Build

npm install
npm run build

Run (stdio mode)

XERO_ACCESS_TOKEN=your-access-token XERO_TENANT_ID=your-tenant-id npm start

Run (HTTP mode)

MCP_TRANSPORT=http XERO_ACCESS_TOKEN=your-access-token XERO_TENANT_ID=your-tenant-id npm start

The server listens on http://0.0.0.0:8080/mcp by default.

Docker

docker build -t xero-mcp .
docker run -p 8080:8080 \
  -e MCP_TRANSPORT=http \
  -e XERO_ACCESS_TOKEN=your-access-token \
  -e XERO_TENANT_ID=your-tenant-id \
  xero-mcp

Environment Variables

Gateway Mode

When AUTH_MODE=gateway, credentials are passed per-request via HTTP headers instead of environment variables:

• X-Xero-Access-Token — OAuth2 access token
• X-Xero-Tenant-Id — Xero tenant ID

This allows a gateway/proxy to manage multi-tenant credentials.
