Xero Automation

Xero Automation

Automate Xero accounting operations including managing invoices, contacts, payments, bank transactions, and chart of accounts for small business bookkeeping.

Toolkit docs: composio.dev/toolkits/xero

Setup

This skill requires the Composio MCP server connected at http://localhost:8787/mcp.

Before executing any tools, ensure an active connection exists for the xero toolkit. If no connection is active, initiate one via COMPOSIO_MANAGE_CONNECTIONS.

Multi-tenant: If you manage multiple Xero organizations, first call XERO_GET_CONNECTIONS to list active tenants and obtain the correct tenant_id for subsequent calls.

Core Workflows
