## About

# QuickBooks MCP Server

Connect Claude Desktop and Claude Code to QuickBooks Online for natural-language accounting. Ask questions about invoices, expenses, reports, and more using plain English.

## What is this?

An [MCP (Model Context Protocol)](https://modelcontextprotocol.io/) server that gives Claude direct access to your QuickBooks Online data. Instead of logging into QuickBooks and clicking through reports, just ask Claude:

> "Show me all overdue invoices sorted by amount"
> "What's our P&L this quarter?"
> "Create an invoice for Acme Corp for $2,500"

The server handles OAuth authentication, API calls, rate limiting, and data formatting.

## Quick Start

### 1. Install

```bash
pip install quickbooks-mcp
```

Or install from source:

```bash
git clone https://github.com/nyxtools/quickbooks-mcp-server.git
cd quickbooks-mcp-server
pip install -e .
```

### 2. Create a QuickBooks Developer App

1. Go to [developer.intuit.com](https://developer.intuit.com/)
2. Create an app and select **QuickBooks Online and Payments**
3. Under **Keys & OAuth**, note your **Client ID** and **Client Secret**
4. Add `http://localhost:8080/callback` as a **Redirect URI**

### 3. Set Environment Variables

```bash
export QBO_CLIENT_ID='your_client_id'
export QBO_CLIENT_SECRET='your_client_secret'
```

### 4. Run OAuth Setup

```bash
python scripts/setup_oauth.py
```

This opens your browser, authorizes with QuickBooks, and stores tokens locally (encrypted). Note the **Realm ID** it prints at the end.

```bash
export QBO_REALM_ID='your_realm_id'
```

### 5. Configure Claude Desktop

Add to your Claude Desktop config (`claude_desktop_config.json`):

```json
{
  "mcpServers": {
    "quickbooks": {
      "command": "quickbooks-mcp",
      "env": {
        "QBO_CLIENT_ID": "your_client_id",
        "QBO_CLIENT_SECRET": "your_client_secret",
        "QBO_REALM_ID": "your_realm_id"
      }
    }
  }
}
```

**Config file locations:**
- macOS: `~/Library/Application Support/Claude/claude_desktop_config.json`
- Windows: `%APPDATA%\Claude\claude_desktop_config.json`
- Linux: `~/.config/Claude/claude_desktop_config.json`

### 6. Start Using It

Restart Claude Desktop and try:
> "What are my current bank account balances?"

## Troubleshooting

### "No QuickBooks tokens found"
Run the OAuth setup:
```bash
python scripts/setup_oauth.py
```

### "Token refresh failed"
Your refresh token may have expired. Re-run OAuth setup.

### "QuickBooks API error (HTTP 403)"
Verify your app has `com.intuit.quickbooks.accounting` scope.

### "Rate limited by QuickBooks"
The server handles rate limiting automatically. If you see this error, wait 60 seconds.

### "This is a premium feature"
Some tools require a license key. [Get one here](https://nyxtools.dev/quickbooks-mcp) or set `LICENSE_KEY` in your environment.

### Sandbox Mode
For testing without affecting real data:
```bash
export QBO_SANDBOX=true
```
Use your Development keys (not Production) from the Intuit developer dashboard.
