Frequently asked questions about the Lexware Office (Accounting & Invoicing) MCP Server
Can I create a new customer record through my agent?
Yes. Use the create_contact tool by providing the company name, contact person, and email. Your agent will format the data according to Lexware Office standards and assign the correct role ('customer' or 'vendor') instantly.
How do I check the payment status of an invoice?
The get_invoice tool retrieves the complete document structure, including the current status (e.g., 'paid', 'open', or 'overdue'). Your agent can summarize these details for you directly in the conversation.
