Implementation Reference

src/handlers/smartDelivery.ts:1172-1211 (handler)

The main handler function that validates the input parameters using isGetFolderByIdParams, creates a SmartDelivery API client, makes a GET request to `/spam-test/folder/{folder_id}`, and returns the formatted JSON response or handles errors.

async function handleGetFolderById(
  args: unknown, 
  apiClient: AxiosInstance,
  withRetry: <T>(operation: () => Promise<T>, context: string) => Promise<T>
) {
  if (!isGetFolderByIdParams(args)) {
    throw new McpError(
      ErrorCode.InvalidParams,
      'Invalid arguments for smartlead_get_folder_by_id'
    );
  }

  try {
    const smartDeliveryClient = createSmartDeliveryClient(apiClient);
    const { folder_id } = args;
    
    const response = await withRetry(
      async () => smartDeliveryClient.get(`/spam-test/folder/${folder_id}`),
      'get folder by ID'
    );

    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:548-562 (schema)

Defines the tool metadata including name, description, category, and input schema requiring a 'folder_id' integer parameter.

export const GET_FOLDER_BY_ID_TOOL: CategoryTool = {
  name: 'smartlead_get_folder_by_id',
  description: 'Get details of a specific folder by ID.',
  category: ToolCategory.SMART_DELIVERY,
  inputSchema: {
    type: 'object',
    properties: {
      folder_id: {
        type: 'integer',
        description: 'ID of the folder to retrieve',
      },
    },
    required: ['folder_id'],
  },
};

src/types/smartDelivery.ts:414-421 (helper)

Type guard function that validates the input arguments match the expected GetFolderByIdParams interface (object with numeric 'folder_id').

export function isGetFolderByIdParams(args: unknown): args is GetFolderByIdParams {
  return (
    typeof args === 'object' &&
    args !== null &&
    'folder_id' in args &&
    typeof (args as GetFolderByIdParams).folder_id === 'number'
  );
}

src/index.ts:217-219 (registration)
Registers the smartDeliveryTools array (which includes this tool) to the MCP tool registry if the smartDelivery category is enabled.
```
if (enabledCategories.smartDelivery) {
  toolRegistry.registerMany(smartDeliveryTools);
}
```
src/handlers/smartDelivery.ts:119-121 (registration)
Switch case in handleSmartDeliveryTool that routes calls to this specific tool handler.
```
case 'smartlead_get_folder_by_id': {
  return handleGetFolderById(args, apiClient, withRetry);
}
```
