How to Connect Xero to ChatGPT

Connect the Xero accounting API to ChatGPT via MCP. Query invoices, bank transactions, and financial reports with natural language using AnythingMCP.

Talk to Your Accounting Data with ChatGPT

Xero has no official MCP connector. With AnythingMCP, you can convert Xero's REST API into an MCP server and let ChatGPT query invoices, bank transactions, and generate financial insights.

Step-by-Step Guide

Step 1: Deploy AnythingMCP

git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && docker compose up -d

Step 2: Get Xero API Credentials

Register at https://developer.xero.com. Create a custom connection app and set the required scopes: accounting.transactions.read, accounting.contacts.read, accounting.reports.read.

Step 3: Create a REST Connector

Create a REST connector with base URL https://api.xero.com/api.xro/2.0. Configure OAuth 2.0 authentication with the Xero tenant ID header.

Step 4: Expose Key Endpoints

  • GET /Invoices — All invoices
  • GET /BankTransactions — Bank transactions
  • GET /Contacts — Customers and suppliers
  • GET /Reports/ProfitAndLoss — P&L report
  • GET /Reports/BalanceSheet — Balance sheet
  • GET /Accounts — Chart of accounts

Step 5: Connect ChatGPT

{
  "mcpServers": {
    "xero": {
      "url": "http://localhost:4000/mcp"
    }
  }
}

Step 6: Query Your Financials

  • "How much do our customers owe us in outstanding invoices?"
  • "What were our total expenses last month?"
  • "Show me the profit and loss for Q1"
  • "Which customers have overdue invoices?"
  • "What's our current bank balance?"

Security Best Practices

  • Use read-only scopes — avoid write permissions
  • Enable AnythingMCP audit logging for compliance
  • Regularly rotate OAuth tokens
