Summary

Create a Fakturownia invoice by sending the supplied JSON object to the create_invoice MCP tool. The JSON must include client_id and a positions array; the default example adds one service position.

Inputs

  • createData (required) — Invoice data as JSON, including client_id and positions. For example, a position can specify name, quantity, total_price_gross, and tax.

Output shape

One or more n8n items containing the parsed MCP result.

If the MCP result is a JSON array, each element becomes a separate item; otherwise, the parsed result becomes one item. Non-JSON text is returned as { "rawText": "…" }. Invalid input JSON or an MCP error fails the operation unless Continue On Fail is enabled.
