Smartlead Simplified MCP Server

Instructions

Implementation Reference

• src/handlers/smartDelivery.ts:797-836 (handler)

  Core execution logic for the smartlead_get_email_content tool. Validates arguments using isEmailContentParams, calls the SmartDelivery API GET /spam-test/report/{spam_test_id}/email-content endpoint, and formats the response as MCP tool result.

  async function handleGetEmailContent(
    args: unknown, 
    apiClient: AxiosInstance,
    withRetry: <T>(operation: () => Promise<T>, context: string) => Promise<T>
  ) {
    if (!isEmailContentParams(args)) {
      throw new McpError(
        ErrorCode.InvalidParams,
        'Invalid arguments for smartlead_get_email_content'
      );
    }
  
    try {
      const smartDeliveryClient = createSmartDeliveryClient(apiClient);
      const { spam_test_id } = args;
      
      const response = await withRetry(
        async () => smartDeliveryClient.get(`/spam-test/report/${spam_test_id}/email-content`),
        'get email content'
      );
  
      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:392-406 (schema)

  Tool schema definition specifying the name, description, category, and input schema (requires spam_test_id as integer). Used for MCP tool registration and validation.

  export const GET_EMAIL_CONTENT_TOOL: CategoryTool = {
    name: 'smartlead_get_email_content',
    description: 'Get details for the email content (raw, HTML) along with campaign and sequence details.',
    category: ToolCategory.SMART_DELIVERY,
    inputSchema: {
      type: 'object',
      properties: {
        spam_test_id: {
          type: 'integer',
          description: 'ID of the spam test to get the email content for',
        },
      },
      required: ['spam_test_id'],
    },
  };

• src/index.ts:217-219 (registration)

  Registers the array of smartDeliveryTools (including smartlead_get_email_content schema) to the MCP tool registry if smartDelivery category is license-enabled.

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

• src/types/smartDelivery.ts:344-351 (schema)

  Runtime type guard function isEmailContentParams used in the handler for input validation, matching the tool inputSchema.

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

• src/index.ts:354-356 (registration)

  Registers the category dispatcher handleSmartDeliveryTool for all SMART_DELIVERY tools, which routes to specific handlers based on tool name.

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