MCP support
Penni exposes QuickBooks bookkeeping capabilities to MCP-compatible clients such as Claude Desktop and Cursor. Users can query financial information and, on the paid plan, create expenses and invoices.

Local server config is the same for every client. Copy it into your client’s MCP config file.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

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:

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

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.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
