      {
        title: 'Import Workflow JSON',

        }).strict(),

      async (params: { workflowJson: Record<string, unknown> }) => {
        const workflow = await post<Record<string, unknown>>('/workflows', params.workflowJson);
        
        return {
          content: [{ type: 'text', text: `✅ Workflow imported!\n\n- ID: ${workflow.id}\n- Name: ${workflow.name}` }],
