Implementation Reference

• src/handlers/smartDelivery.ts:715-754 (handler)

  Main handler function that validates arguments using isSenderAccountsParams, creates a SmartDelivery API client, performs a GET request to retrieve sender accounts for the given spam_test_id, and returns the formatted JSON response or error.

  async function handleGetSenderAccounts(
    args: unknown, 
    apiClient: AxiosInstance,
    withRetry: <T>(operation: () => Promise<T>, context: string) => Promise<T>
  ) {
    if (!isSenderAccountsParams(args)) {
      throw new McpError(
        ErrorCode.InvalidParams,
        'Invalid arguments for smartlead_get_sender_accounts'
      );
    }
  
    try {
      const smartDeliveryClient = createSmartDeliveryClient(apiClient);
      const { spam_test_id } = args;
      
      const response = await withRetry(
        async () => smartDeliveryClient.get(`/spam-test/report/${spam_test_id}/sender-accounts`),
        'get sender accounts'
      );
  
      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:360-374 (schema)

  Tool definition including name, description, category (SMART_DELIVERY), and input schema requiring 'spam_test_id' as integer.

  export const GET_SENDER_ACCOUNTS_TOOL: CategoryTool = {
    name: 'smartlead_get_sender_accounts',
    description: 'Get the list of all sender accounts selected for a specific spam test.',
    category: ToolCategory.SMART_DELIVERY,
    inputSchema: {
      type: 'object',
      properties: {
        spam_test_id: {
          type: 'integer',
          description: 'ID of the spam test to get the sender accounts for',
        },
      },
      required: ['spam_test_id'],
    },
  };

• src/index.ts:217-219 (registration)

  Registers the array of smartDeliveryTools (which includes smartlead_get_sender_accounts) to the tool registry if smartDelivery category is enabled.

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

• src/types/smartDelivery.ts:326-333 (schema)

  Type guard function for validating input parameters matching SenderAccountsParams interface (spam_test_id: number).

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

• src/handlers/smartDelivery.ts:86-88 (registration)

  Switch case in handleSmartDeliveryTool that routes the tool call to the specific handleGetSenderAccounts implementation.

  case 'smartlead_get_sender_accounts': {
    return handleGetSenderAccounts(args, apiClient, withRetry);
  }
