It can create and update organizations, contacts, products, draft quotes and draft invoices, convert a quote into an invoice, finalize invoices and quotes, set an invoice to final or paid, create credit notes and email documents to customers.

Does the AI see my Sinao API key?

No. Your Sinao 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. Finalizing an invoice gives it a definitive number and locks it, and emailing documents sends real emails right away. These actions can require your approval before they run. Every tool call is logged.

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 Sinao account.

What is the company (app) ID?

A Sinao API key is tied to one company, and the company ID is the number Sinao uses for that company in its API addresses. If you do not know it, the AI can call the List apps tool, which shows the companies your key can access with their IDs.
