Implementation Reference

• src/handlers/statistics.ts:267-307 (handler)

  Core execution logic: validates parameters, queries Smartlead API `/campaigns/{campaign_id}/lead-statistics`, returns JSON data or error response.

  async function handleCampaignLeadStatistics(
    args: unknown,
    apiClient: AxiosInstance,
    withRetry: <T>(operation: () => Promise<T>, context: string) => Promise<T>
  ) {
    if (!isCampaignLeadStatisticsParams(args)) {
      throw new McpError(
        ErrorCode.InvalidParams,
        'Invalid arguments for smartlead_get_campaign_lead_statistics'
      );
    }
  
    const { campaign_id, ...queryParams } = args;
  
    try {
      const response = await withRetry(
        async () => apiClient.get(`/campaigns/${campaign_id}/lead-statistics`, {
          params: queryParams
        }),
        'get campaign lead statistics'
      );
  
      return {
        content: [
          {
            type: 'text',
            text: JSON.stringify(response.data, null, 2),
          },
        ],
        isError: false,
      };
    } catch (error: any) {
      return {
        content: [{ 
          type: 'text', 
          text: `API Error: ${error.response?.data?.message || error.message}` 
        }],
        isError: true,
      };
    }
  }

• src/tools/statistics.ts:124-154 (schema)

  Tool metadata and input schema definition specifying parameters for campaign lead statistics query.

  export const CAMPAIGN_LEAD_STATISTICS_TOOL: CategoryTool = {
    name: 'smartlead_get_campaign_lead_statistics',
    description: 'Fetch lead statistics for a campaign.',
    category: ToolCategory.CAMPAIGN_STATISTICS,
    inputSchema: {
      type: 'object',
      properties: {
        campaign_id: {
          type: 'number',
          description: 'ID of the campaign to fetch lead statistics for',
        },
        limit: {
          type: 'number',
          description: 'Maximum number of leads to return (max 100)',
        },
        created_at_gt: {
          type: 'string',
          description: 'Filter by leads created after this date (YYYY-MM-DD format)',
        },
        event_time_gt: {
          type: 'string',
          description: 'Filter by events after this date (YYYY-MM-DD format)',
        },
        offset: {
          type: 'number',
          description: 'Offset for pagination',
