Questions

What can the AI do in Frihet?

It can search and read customers, invoices, quotes, expenses, suppliers and products, download invoice PDFs and get a financial summary and a snapshot of your business. It can create and update invoices, quotes, customers and expenses, create suppliers and products, add customer notes, mark invoices as paid and email invoices and quotes.

Does the AI see my Frihet credentials?

No. Your Frihet API key is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start read-only. Sending an invoice or a quote emails your client, so those tools can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT, open Settings › Apps & Connectors › Advanced, turn on Developer mode and add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Frihet account.

Does marking an invoice as paid move any money?

No. It only records the payment in Frihet, with a payment date that defaults to today. No money is collected or transferred. Use it once the client has actually paid you.
