Implementation Reference

• src/handlers/smartDelivery.ts:428-467 (handler)

  Core handler function that executes the tool: validates input using isProviderWiseReportParams, calls SmartDelivery API POST /spam-test/report/{spam_test_id}/providerwise, returns formatted JSON response or error message.

  async function handleGetProviderWiseReport(
    args: unknown, 
    apiClient: AxiosInstance,
    withRetry: <T>(operation: () => Promise<T>, context: string) => Promise<T>
  ) {
    if (!isProviderWiseReportParams(args)) {
      throw new McpError(
        ErrorCode.InvalidParams,
        'Invalid arguments for smartlead_get_provider_wise_report'
      );
    }
  
    try {
      const smartDeliveryClient = createSmartDeliveryClient(apiClient);
      const { spam_test_id } = args;
      
      const response = await withRetry(
        async () => smartDeliveryClient.post(`/spam-test/report/${spam_test_id}/providerwise`),
        'get provider wise report'
      );
  
      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/smartDelivery.ts:248-262 (schema)

  Tool definition with input schema: requires spam_test_id (integer). Used for MCP tool registration and validation.

  export const GET_PROVIDER_WISE_REPORT_TOOL: CategoryTool = {
    name: 'smartlead_get_provider_wise_report',
    description: 'Get detailed report of a spam test sorted by email providers.',
    category: ToolCategory.SMART_DELIVERY,
    inputSchema: {
      type: 'object',
      properties: {
        spam_test_id: {
          type: 'integer',
          description: 'ID of the spam test to get the provider-wise report for',
        },
      },
      required: ['spam_test_id'],
    },
  };

• src/index.ts:217-219 (registration)

  Registers the smartDeliveryTools array (including this tool) to the MCP toolRegistry if smartDelivery category enabled by license.

  if (enabledCategories.smartDelivery) {
    toolRegistry.registerMany(smartDeliveryTools);
  }

• src/index.ts:354-355 (registration)

  Top-level tool dispatch in CallToolRequest handler: routes SMART_DELIVERY tools to handleSmartDeliveryTool.

  case ToolCategory.SMART_DELIVERY:
    return await handleSmartDeliveryTool(name, toolArgs, apiClient, withRetry);

• src/handlers/smartDelivery.ts:65-67 (registration)

  Dispatches this specific tool name to the handleGetProviderWiseReport function within handleSmartDeliveryTool switch.

  case 'smartlead_get_provider_wise_report': {
    return handleGetProviderWiseReport(args, apiClient, withRetry);
  }

• src/types/smartDelivery.ts:263-270 (schema)

  Type guard function for input validation: checks for object with spam_test_id as number.

  export function isProviderWiseReportParams(args: unknown): args is ProviderWiseReportParams {
    return (
      typeof args === 'object' &&
      args !== null &&
      'spam_test_id' in args &&
      typeof (args as ProviderWiseReportParams).spam_test_id === 'number'
    );
  }
