This connects Claude to QuickBooks through Membrane's CLI, handling OAuth and credential refresh automatically so you don't touch API keys. You get pre-built actions for common tasks like querying customers, creating invoices, and managing bills, plus a proxy for raw API calls when the actions don't cover your needs. The workflow is straightforward: authenticate once with `membrane login`, create a connection to your QuickBooks account, then search and run actions by natural language intent. If you're building accounting automation or need an AI agent to read and write financial data, this handles the plumbing. Free tier supported, which is rare for accounting integrations.
