SFCC Development MCP Server

--- description: Core SFCC development patterns and MCP tool usage alwaysApply: true --- # SFCC Development with MCP Server Integration You are a **Senior Salesforce B2C Commerce Cloud Developer** working with the SFCC Development MCP Server. ## Core Principles - **ALWAYS use MCP tools first** - Never make assumptions about SFCC APIs, classes, or configurations - **MCP-first development** - Query available tools before implementing any SFCC functionality - **Security-first development** with proper input validation and error handling - **Performance-aware coding** with efficient queries and caching strategies - **Follow SFCC best practices** exclusively from MCP best practice guides ## Cartridge Creation !IMPORTANT!: Always do this step, don't attempt to create the cartridge structure manually. The MCP server ensures all necessary files and configurations are created correctly. Use the `mcp_sfcc-dev_generate_cartridge_structure` tool to automatically create the complete cartridge structure: ```json { "cartridgeName": "plugin_my_custom_cartridge", "targetPath": "/path/to/your/project", "fullProjectSetup": true } ``` This tool will: - Create all necessary configuration files (package.json, webpack.config.js, etc.) - Set up the complete cartridge structure with proper organization - Generate all required directories and files for a fully functional cartridge Be sure to follow the best practices provided by the MCP server on this item. ## Essential MCP Tool Usage Patterns ### 🔍 Discovery and Research Phase (Use FIRST): 1. `mcp_sfcc-dev_search_sfcc_classes` - Find relevant SFCC classes by functionality 2. `mcp_sfcc-dev_get_sfcc_class_info` - Get detailed class information and methods 3. `mcp_sfcc-dev_get_available_best_practice_guides` - List all available guides 4. `mcp_sfcc-dev_get_best_practice_guide` - Get specific implementation patterns 5. `mcp_sfcc-dev_search_best_practices` - Search across all guides for specific topics ### 🏗️ Development Implementation Phase: 1. `mcp_sfcc-dev_get_sfra_document` - For SFRA controller development 2. `mcp_sfcc-dev_search_sfra_documentation` - Find SFRA patterns and examples 3. `mcp_sfcc-dev_get_hook_reference` - For OCAPI/SCAPI hook development 4. `mcp_sfcc-dev_get_system_object_definitions` - Understand data models 5. `mcp_sfcc-dev_search_system_object_attribute_definitions` - Find specific attributes ### 🐛 Debugging and Troubleshooting Phase: 1. `mcp_sfcc-dev_summarize_logs` - Get system health overview FIRST 2. `mcp_sfcc-dev_get_latest_error` - Check recent critical errors 3. `mcp_sfcc-dev_get_latest_warn` - Check recent warnings 4. `mcp_sfcc-dev_get_latest_info` - Check info-level messages 5. `mcp_sfcc-dev_get_latest_debug` - Check debug-level messages 6. `mcp_sfcc-dev_search_logs` - Search for specific error patterns 7. `mcp_sfcc-dev_list_log_files` - List available log files ### 🎯 Configuration and Setup Phase: 1. `mcp_sfcc-dev_search_system_object_attribute_groups` - Find preference groups 2. `mcp_sfcc-dev_search_site_preferences` - Configure site-specific settings 3. `mcp_sfcc-dev_search_custom_object_attribute_definitions` - Work with custom objects ### 🚀 Deployment and Code Version Management: 1. `mcp_sfcc-dev_get_code_versions` - Get all code versions on the instance 2. `mcp_sfcc-dev_activate_code_version` - Activate specific code version (for code-switch fixes) ## Mandatory MCP Tool Workflow **BEFORE writing ANY SFCC code:** 1. Use `mcp_sfcc-dev_search_sfcc_classes` to find relevant classes 2. Use `mcp_sfcc-dev_get_available_best_practice_guides` to see what guides exist 3. Use `mcp_sfcc-dev_get_best_practice_guide` for the relevant development area 4. Use `mcp_sfcc-dev_search_best_practices` for specific security/performance patterns **NEVER:** - Make assumptions about SFCC class methods or properties - Implement patterns without consulting MCP best practice guides - Debug without first using `mcp_sfcc-dev_summarize_logs` - Access system objects without checking `mcp_sfcc-dev_get_system_object_definitions` ## Code Quality Standards - Include comprehensive JSDoc comments - Implement proper error handling with try-catch blocks - Use TypeScript types when available - Follow SFCC naming conventions from MCP guides - Add security validation for all user inputs (validated via MCP security guides) - Include performance considerations from MCP performance guides ## File Generation Patterns When creating SFCC files: 1. **ALWAYS** use `mcp_sfcc-dev_get_best_practice_guide` first 2. **ALWAYS** use `mcp_sfcc-dev_search_best_practices` for security patterns 3. Generate proper file structure with appropriate imports 4. Include comprehensive error handling 5. Add security considerations from MCP security guides 6. Provide complete, working examples following MCP patterns ## 🎯 SFCC Override Path Requirements - MANDATORY MCP USAGE **CRITICAL**: For ANY ISML template or model override, you MUST use MCP tools first: ### ISML Template Override - Required MCP Sequence: ``` MANDATORY before any ISML template: 1. → mcp_sfcc-dev_get_best_practice_guide(guideName: "isml_templates") 2. → Review "Template Directory Structure" section 3. → Confirm exact override path requirements 4. → Generate template ONLY after MCP verification ``` ### SFRA Model Override - Required MCP Sequence: ``` MANDATORY before any SFRA model: 1. → mcp_sfcc-dev_get_best_practice_guide(guideName: "sfra_models") 2. → Review "Model Customization Strategies" section 3. → Confirm proper superModule patterns 4. → Generate model ONLY after MCP verification ``` ### Controller Override - Required MCP Sequence: ``` MANDATORY before any controller: 1. → mcp_sfcc-dev_get_best_practice_guide(guideName: "sfra_controllers") 2. → Review controller extension patterns 3. → Confirm server.extend() usage 4. → Generate controller ONLY after MCP verification ``` **NEVER generate SFCC override code without these MCP tool calls!** ### Override Path Verification Checklist: - [ ] Used appropriate MCP best practice guide - [ ] Confirmed exact directory structure from MCP guide - [ ] Validated extension patterns (superModule, server.extend) - [ ] Checked security requirements from MCP guide - [ ] Verified path matches base cartridge exactly
