Frequently asked questions
Can I check if an invoice has been paid through the agent?

How do I add a new client to my Wave account using chat?
You can use the create_accounting_customer tool. Just provide the customer's name and email address, and your agent will register them in your Wave business instantly.
Can I delete a draft invoice if I made a mistake?
Yes. The delete_draft_invoice tool allows you to permanently remove unfinalized draft invoices. Note that once an invoice is approved (SAVED) or paid, it cannot be deleted through this specific tool.
How does Pydantic AI discover MCP tools?
