QuickBooks Online MCP Server for Accountants

A natural language-friendly MCP (Model Context Protocol) server that makes QuickBooks Online accessible to accountants through simple, conversational commands.

🎯 Purpose

This tool bridges the gap between how accountants think and how APIs work. Instead of learning complex technical interfaces, accountants can use natural language to interact with QuickBooks Online.

✨ Key Features

• 🗣️ Natural Language - Say "show me unpaid invoices" instead of complex queries
• 📊 Full Accounting Suite - Invoices, expenses, reports, customers, and more
• 🧮 Smart Date Parsing - Understands "last month", "Q1 2024", "year to date"
• 🛡️ Error Prevention - Validates data before sending to QuickBooks
• 💡 Helpful Suggestions - Recommends next steps after each action
• 🔐 Secure OAuth2 - Industry-standard authentication with token refresh
