🤖 AI Assistant Integration

For optimal AI assistance when working with SFCC projects, copy the sfcc-ai-instructions.md file to your SFCC project directory and rename it to copilot-instructions.md, claude.md, or similar. This file provides comprehensive guidance to AI assistants on:

• When to use MCP tools vs. relying on general AI knowledge
• Specific tool recommendations for common SFCC development tasks
• Workflow patterns for debugging, implementation, and best practices
• Error reduction by encouraging use of current, verified SFCC information

This significantly improves AI assistance accuracy and reduces hallucination when working on SFCC development tasks.

An MCP (Model Context Protocol) server that provides comprehensive access to Salesforce B2C Commerce Cloud development features. This allows AI agents to assist with SFCC development tasks including log analysis, debugging, monitoring, and SFCC documentation querying.

This provides more detailed attribute information than the basic system object definition.
• Search System Object Attribute Definitions: Search for specific attribute definitions within a system object type using complex queries. Supports text search on id/display_name/description, filtering by properties like mandatory/searchable/system, and sorting. Essential for finding custom attributes or attributes with specific characteristics.
• Search Site Preferences: Search site preferences across sites in the specified preference group and instance. Essential for discovering custom site preferences, understanding preference configurations, or when working with site-specific settings. Supports complex queries with text search, filtering, and sorting.
• Search System Object Attribute Groups: Search attribute groups for a specific system object type. Essential for discovering site preference groups (use "SitePreferences" as objectType) needed for the site preferences search API. Supports complex queries with text search, filtering, and sorting on group properties.

Note: System object definition tools require OAuth credentials (clientId and clientSecret) and are useful for discovering custom attributes and site preferences added to standard SFCC objects.

Installation

1. Clone this repository
2. Install dependencies:
   npm install
3. Build the TypeScript code:
   npm run build

Configuration

Overriding the Working Directory

The server uses the current working directory (cwd) to locate documentation files. By default, it expects to find a docs/ folder in the directory where the server is started. If you need to use documentation from a different location, you have several options:

Option 1: Start the server from the correct directory

Option 2: Use the --cwd flag (if your MCP client supports it)

Option 3: Create symbolic links

Expected Directory Structure: The server expects the following structure relative to the working directory:

Using dw.json (Recommended)

The server supports the standard SFCC dw.json configuration format used by Commerce Cloud development tools. Create a dw.json file in your project root:

Required fields:

• hostname: Your SFCC instance hostname
• username: Your SFCC username
• password: Your SFCC password

Optional fields:

• client-id: OAuth client ID (for API access)
• client-secret: OAuth client secret (for API access)
• code-version: Code version to use

Using Environment Variables

Alternatively, you can configure the server using environment variables:

Data API Configuration

Business Manager Setup for System Object Definition Tools

To use the system object definition tools (get_system_object_definitions, get_system_object_definition, get_system_object_attribute_definitions, search_system_object_attribute_definitions, search_site_preferences, search_system_object_attribute_groups), you need to configure Data API access in Business Manager:

Step 1: Create API Client in Account Manager

1. Log into Account Manager (not Business Manager)
2. Navigate to API Client section
3. Click Add API Client
4. Configure the API client:
   • Name: SFCC Dev MCP Server (or any descriptive name)
   • Password: Generate a secure password
   • Scopes: Select SFCC scope
   • Roles: Assign appropriate roles for your organization

Step 2: Configure Data API Access in Business Manager

1. Log into Business Manager for your instance
2. Navigate to Administration > Site Development > Open Commerce API Settings
3. Click on Data API tab
4. Configure the following settings:

Client Configuration:

Required Settings:

• Client ID: Your API client ID (e.g., aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa)
• Resource ID: /system_object_definitions/* (allows access to all system object definition endpoints)
• Resource ID: /site_preferences/preference_groups/*/*/preference_search (allows access to site preferences search)
• Methods: get and post (required for retrieving and searching system objects and preferences)
• Read Attributes: (**) (allows reading all attributes)
• Write Attributes: (**) (may be required for some operations)

Step 3: Update Your Configuration

Add the client credentials to your dw.json:

Troubleshooting Data API Access

Common Issues:

• 403 Forbidden: Check that your API client has the correct scopes and roles
• 401 Unauthorized: Verify your client credentials are correct
• Resource not found: Ensure the resource ID pattern matches /system_object_definitions/* and /site_preferences/preference_groups/*/*/preference_search

Testing Your Configuration: You can test your Data API access using the MCP tools:

Usage

Launch Parameters and Command Line Options

The server supports several command line parameters to customize its behavior:

--dw-json <path>

Specify a custom path to your dw.json configuration file:

--debug <true|false>

Control debug logging output to customize the verbosity of server logs:

Debug logging includes:

• Method entry and exit logs
• Detailed timing information for operations
• Full response previews for debugging
• Additional context for troubleshooting

Production usage: Use --debug false in production environments to reduce log noise and improve performance.

Configuration Loading Priority

The server loads configuration in the following order of preference:

1. Command line --dw-json argument (highest priority)
   • Allows you to specify a custom path to your dw.json file
   • Useful for different environments or project configurations
2. ./dw.json file in current directory
   • Automatically detected if present in the working directory
   • Standard SFCC development workflow
3. Environment variables (lowest priority)
   • Falls back to environment variables if no dw.json is found
   • See the "Using Environment Variables" section below

Starting the Server

Using with npx

You can also run the server directly using npx without installing it locally:

Note: When using npx, make sure your dw.json file is in the current working directory or specify the full path using the --dw-json parameter.

MCP Client Configuration

Add this server to your MCP client configuration. For example, in Claude Desktop's config:

Using Local Installation

Using npx (Recommended)

You can configure the MCP client to use npx, which automatically handles package installation and updates:

Example configurations:

For automatic configuration detection (uses ./dw.json in working directory):

Benefits of using npx in MCP configuration:

• Automatically installs the latest version if not present
• No need to manually clone or build the project
• Automatic updates when new versions are released
• Consistent behavior across different environments
• Easy to share configurations with team members
