What is MCP invoicing?
Invoicing through the AI assistant you already use, over an open standard called Model Context Protocol. You describe the work in chat, the assistant prepares the invoice, and you approve and send it.
Is it really free?
Yes. There is no subscription, no monthly fee, and no invoice limit. You pay 5.9% + $0.59 only when a client pays an invoice through Stripe.
Can the assistant send invoices without my approval?
No. Drafts never send on their own. You approve every send in the chat before anything goes to a client.
