Implementation Reference

• src/tools/scaffold.ts:483-529 (handler)

  The async handler function registered for 'scaffold_macos_project' that handles parameters, calls the core scaffoldProject function, formats success/error responses, and returns MCP content.

  async (params) => {
    try {
      const projectParams: ScaffoldProjectParams = { ...params, platform: 'macOS' };
      const projectPath = await scaffoldProject(projectParams);
  
      const response = {
        success: true,
        projectPath,
        platform: 'macOS',
        message: `Successfully scaffolded macOS project "${params.projectName}" at ${projectPath}`,
        nextSteps: [
          `Open the project: open ${projectPath}/${params.customizeNames ? params.projectName : 'MyProject'}.xcworkspace`,
          `Build for macOS: build_mac_ws --workspace-path "${projectPath}/${params.customizeNames ? params.projectName : 'MyProject'}.xcworkspace" --scheme "${params.customizeNames ? params.projectName : 'MyProject'}"`,
          `Run and run on macOS: build_run_mac_ws --workspace-path "${projectPath}/${params.customizeNames ? params.projectName : 'MyProject'}.xcworkspace" --scheme "${params.customizeNames ? params.projectName : 'MyProject'}"`,
        ],
      };
  
      return {
        content: [
          {
            type: 'text',
            text: JSON.stringify(response, null, 2),
          },
        ],
      };
    } catch (error) {
      log(
        'error',
        `Failed to scaffold macOS project: ${error instanceof Error ? error.message : String(error)}`,
      );
  
      return {
        content: [
          {
            type: 'text',
            text: JSON.stringify(
              {
                success: false,
                error: error instanceof Error ? error.message : 'Unknown error occurred',
              },
              null,
              2,
            ),
          },
        ],
      };
    }

• src/tools/scaffold.ts:62-67 (schema)

  macOS-specific Zod schema for scaffold_macos_project parameters, extending the base schema with deploymentTarget.

  const ScaffoldmacOSProjectSchema = BaseScaffoldSchema.extend({
    deploymentTarget: z
      .string()
      .optional()
      .describe('macOS deployment target (e.g., 15.4, 14.0). If not provided, will use 15.4'),
  });

• src/tools/scaffold.ts:478-482 (registration)

  Registration of the 'scaffold_macos_project' tool using registerTool, specifying name, description, and schema.

  registerTool<ScaffoldmacOSProjectParams>(
    server,
    'scaffold_macos_project',
    'Scaffold a new macOS project from templates. Creates a modern Xcode project with workspace structure, SPM package for features, and proper macOS configuration.',
    ScaffoldmacOSProjectSchema.shape,

• src/tools/scaffold.ts:380-418 (helper)

  Core helper function that performs the actual project scaffolding: validates params, gets template, processes directory recursively, handles cleanup.

  async function scaffoldProject(params: ScaffoldProjectParams): Promise<string> {
    const { projectName, outputPath, platform, customizeNames = true } = params;
  
    log('info', `Scaffolding project: ${projectName} (${platform}) at ${outputPath}`);
  
    // Validate project name
    if (!/^[a-zA-Z][a-zA-Z0-9_]*$/.test(projectName)) {
      throw new ValidationError(
        'Project name must start with a letter and contain only letters, numbers, and underscores',
      );
    }
  
    // Get template path from TemplateManager
    let templatePath: string;
    try {
      templatePath = await TemplateManager.getTemplatePath(platform);
    } catch (error) {
      throw new ValidationError(
        `Failed to get template for ${platform}: ${error instanceof Error ? error.message : String(error)}`,
      );
    }
  
    // Create output directory
    const projectPath = join(outputPath, customizeNames ? projectName : 'MyProject');
  
    if (existsSync(projectPath)) {
      throw new ValidationError(`Project directory already exists at ${projectPath}`);
    }
  
    try {
      // Process the template
      await processDirectory(templatePath, projectPath, params);
  
      return projectPath;
    } finally {
      // Clean up downloaded template if needed
      await TemplateManager.cleanup(templatePath);
    }
  }

• src/tools/scaffold.ts:149-241 (helper)

  Helper function to update .xcconfig files with project parameters, bundle ID, versions, deployment targets, orientations, and platform-specific settings.
