Summary

Connects QuickBooks Online to Claude Desktop so you can query financials and manage books through natural language. Free tier gives you read access: bank balances, P&L reports, invoice status, and basic account data. Paid tier ($149/mo) adds write operations like creating expenses, generating invoices, and AI-powered bookkeeping analysis. Uses a secure API that keeps your data in your own QuickBooks account. Setup is straightforward with npx, and you'll need an API key from their dashboard. Useful if you're already on QuickBooks and want to skip the web interface for routine bookkeeping tasks.

penni-mcp

Penni — AI bookkeeper for small businesses. Connect your QuickBooks and manage your books through Claude Desktop or Cursor.

Quick Start

npx penni-mcp

On first run, you'll be prompted for your API key. Get yours at app.penni.so/dashboard/mcp.

Claude Desktop Setup

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "penni": {
      "command": "npx",
      "args": ["penni-mcp"]
    }
  }
}

Config file location:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json

Then restart Claude Desktop and ask: "What's my bank balance?"

Cursor Setup

Settings → MCP → Add Server:

  • Name: penni
  • Command: npx penni-mcp

What You Can Do

Free (connect QBO and go)

  • "What's my bank balance?" — real-time balances from QuickBooks
  • "Show me my P&L for this month" — Profit & Loss report
  • "Who owes me money?" — open and overdue invoices

Paid ($149/mo at penni.so)

  • "Create a $500 expense for AWS under Software" — post expenses to QBO
  • "Invoice Acme Corp $2,000 for consulting, due May 1st" — create and send invoices
  • "Ask Penni: what's my biggest expense category?" — AI-powered bookkeeping Q&A

How It Works

Penni connects to your QuickBooks Online account through a secure API. Your data lives in YOUR QuickBooks — not on our servers. If you stop using Penni, your books are exactly where they've always been.

API Key

You can also set your API key via environment variable:

PENNI_API_KEY=your_key_here npx penni-mcp

Or pass it as a flag:

npx penni-mcp --key your_key_here

The key is saved to ~/.penni/config.json after first run.
