Summary

Updates a contractor in Fakturownia by calling the update_contractor MCP tool with the contractor ID and fields parsed from the JSON input.

Inputs

  • Contractor ID (required) — The ID of the contractor to update.
  • Update Fields (JSON) (required) — A JSON object of fields to update. Its properties are spread into the tool arguments alongside id; invalid JSON causes an operation error.

Output shape

A single n8n item containing the parsed MCP result as its JSON body, or multiple items if the result is an array.

Each returned item is paired with its input item. If the MCP result text is not valid JSON, the output body contains it under rawText. With Continue On Fail enabled, errors are returned as an item with an error field.
