Accounting connector: invoices, payments, and cash position on request

An MCP connector for Xero that lets finance teams ask an AI assistant who owes what, which invoices are overdue, and what cash looks like, and draft invoices and reminders for approval.

Type: AI agent integration (MCP)
Tools: 5 agent tools
Stack: TypeScript, MCP SDK, Xero API

The problem

Finance teams answer the same questions every week: what's overdue, has this customer paid, what's our cash position? The answers are in the accounting system, behind reports nobody wants to run.

The solution

A connector over the Xero API turns those questions into tools. Reporting is read-only; anything that sends money or messages to customers is drafted and approved by a person.

Tools the agent can use

overdue_invoicesOverdue receivables by customer and ageRead

payment_statusWhether and when an invoice was paidRead

cash_summaryBank balances and expected inflows and outflowsRead

draft_invoiceDraft an invoice for review in XeroNeeds approval

draft_reminderDraft a payment reminder for a person to sendNeeds approval
