Implementation Reference

• src/handlers/smartDelivery.ts:920-959 (handler)

  The core handler function that validates input parameters using isScheduleHistoryParams, creates a SmartDelivery API client, fetches the schedule history from `/spam-test/report/${spam_test_id}/schedule-history` endpoint using retry logic, and returns formatted JSON response or error message.

  async function handleGetScheduleHistory(
    args: unknown, 
    apiClient: AxiosInstance,
    withRetry: <T>(operation: () => Promise<T>, context: string) => Promise<T>
  ) {
    if (!isScheduleHistoryParams(args)) {
      throw new McpError(
        ErrorCode.InvalidParams,
        'Invalid arguments for smartlead_get_schedule_history'
      );
    }
  
    try {
      const smartDeliveryClient = createSmartDeliveryClient(apiClient);
      const { spam_test_id } = args;
      
      const response = await withRetry(
        async () => smartDeliveryClient.get(`/spam-test/report/${spam_test_id}/schedule-history`),
        'get schedule history'
      );
  
      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:444-458 (schema)

  Defines the tool metadata including name, description, category (SMART_DELIVERY), and input schema that requires a single 'spam_test_id' parameter of type integer.

  export const GET_SCHEDULE_HISTORY_TOOL: CategoryTool = {
    name: 'smartlead_get_schedule_history',
    description: 'Get the list and summary of all tests that ran for a particular automated test.',
    category: ToolCategory.SMART_DELIVERY,
    inputSchema: {
      type: 'object',
      properties: {
        spam_test_id: {
          type: 'integer',
          description: 'ID of the automated spam test to get the schedule history for',
        },
      },
      required: ['spam_test_id'],
    },
  };

• src/index.ts:217-219 (registration)

  Registers the smartDeliveryTools array (which includes smartlead_get_schedule_history) to the tool registry if the smartDelivery category is enabled by license/features.

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

• src/handlers/smartDelivery.ts:101-103 (registration)

  Routes the tool call to the specific handleGetScheduleHistory implementation within the SmartDelivery tool dispatcher.

  case 'smartlead_get_schedule_history': {
    return handleGetScheduleHistory(args, apiClient, withRetry);
  }

• src/types/smartDelivery.ts:373-380 (helper)

  Type guard function used for input validation, ensuring args is an object containing 'spam_test_id' as a number.

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