Implementation Reference

• src/tools/audit-utils.ts:183-221 (handler)

  The implementation of the `n8n_export_workflow` tool, which retrieves a workflow by ID, sanitizes it by removing instance-specific fields, and returns the JSON.

    server.registerTool(
      'n8n_export_workflow',
      {
        title: 'Export Workflow JSON',
        description: `Export a workflow as JSON for backup or import elsewhere.
  
  Args:
    - id (string): Workflow ID to export
  
  Returns:
    Complete workflow JSON that can be imported into another n8n instance.`,
        inputSchema: z.object({
          id: z.string().min(1).describe('Workflow ID to export')
        }).strict(),
        annotations: {
          readOnlyHint: true,
          destructiveHint: false,
          idempotentHint: true,
          openWorldHint: false
        }
      },
      async (params: { id: string }) => {
        const workflow = await get<Record<string, unknown>>(`/workflows/${params.id}`);
        
        // Remove instance-specific fields for export
        const exportable = { ...workflow };
        delete exportable.id;
        delete exportable.createdAt;
        delete exportable.updatedAt;
        delete exportable.versionId;
        
        const json = JSON.stringify(exportable, null, 2);

          content: [{ type: 'text', text: `**Exported Workflow: ${(workflow as { name?: string }).name || params.id}**\n\n\`\`\`json\n${json}\n\`\`\`` }],
