SFCC Development MCP Server

An AI-powered Model Context Protocol (MCP) server that provides comprehensive access to Salesforce B2C Commerce Cloud development tools, documentation, and best practices.

✨ Key Features

• 🔍 Complete SFCC Documentation Access - Search and explore all SFCC API classes and methods
• 📚 Best Practices Guides - Curated development guidelines for cartridges, hooks, controllers, client-side JavaScript, and more
• 🏗️ SFRA Documentation - Enhanced access to Storefront Reference Architecture documentation
• 📊 Log Analysis Tools - Real-time error monitoring, debugging, and job log analysis for SFCC instances
• ⚙️ System Object Definitions - Explore custom attributes and site preferences
• 🚀 Cartridge Generation - Automated cartridge structure creation

🚀 Quick Start

Option 1: Documentation-Only Mode (No SFCC credentials needed)

{
  "mcpServers": {
    "sfcc-dev": {
      "command": "npx",
      "args": ["sfcc-dev-mcp"]
    }
  }
}

Option 2: Full Mode (With SFCC credentials for log and job analysis)

{
  "mcpServers": {
    "sfcc-dev": {
      "command": "npx",
      "args": ["sfcc-dev-mcp", "--dw-json", "/path/to/your/dw.json"]
    }
  }
}

Create a dw.json file with your SFCC credentials:

{
  "hostname": "your-instance.sandbox.us01.dx.commercecloud.salesforce.com",
  "username": "your-username",
  "password": "your-password", 
  "client-id": "your-client-id",
  "client-secret": "your-client-secret"
}

� Architecture Overview

This server is built around a capability-gated, modular handler architecture that cleanly separates tool routing from domain logic:

Core Layers

• Tool Definitions (src/core/tool-definitions.ts): Declarative schemas grouped by category (documentation, best practices, SFRA, logs, job logs, system objects, cartridge generation, code versions).
• Handlers (src/core/handlers/*.ts): Each category has a handler extending a common base for timing, structured logging, and error normalization (e.g. log-handler, docs-handler, system-object-handler).
• Clients (src/clients/): Encapsulate domain operations (OCAPI, SFRA docs, best practices, modular log analysis). Handlers delegate to these so orchestration and computation remain separate.
• Services (src/services/): Dependency-injected abstractions for filesystem and path operations — improves testability and isolates side effects.
• Modular Log System (src/clients/logs/): Reader (range/tail optimization), discovery, processor (line → structured entry), analyzer (patterns & health), formatter (human output) for maintainable evolution.
• Configuration Factory (src/config/configuration-factory.ts): Determines capabilities (canAccessLogs, canAccessOCAPI) based on provided credentials and filters exposed tools accordingly (principle of least privilege).

Why This Matters

• Extensibility: Adding a new tool usually means adding a schema + minimal handler logic (or a new handler if a new domain).
• Security: Tools that require credentials are never exposed when capability flags are false.
• Testability: Unit tests target clients & modules; integration/MCP tests validate handler routing and response structure.
• Performance: Tail log reads + lightweight caching (cache.ts, log-cache.ts) reduce unnecessary I/O.

Adding a New Tool (High-Level)

1. Add schema object to the correct exported array in tool-definitions.ts.
2. Implement domain logic in a client/service (avoid bloating handlers).
3. Extend an existing handler or create a new one if it's a new category.
4. (Only for a new category) register the new handler inside registerHandlers() in server.ts.
5. Discover actual response shape with npx mcp-aegis query before writing tests.
6. Add Jest unit tests + YAML MCP tests (docs vs full mode if credentials required).
7. Update documentation (Development Guide + README counts if changed).

�🤖 AI Interface Setup

Choose your preferred AI assistant:

| Interface | Best For | Setup Guide | |-----------|----------|-------------| | Claude Desktop | Multi-turn conversations, debugging | 📖 Setup Guide | | GitHub Copilot | VS Code integration, inline suggestions | 📖 Setup Guide | | Cursor | Modern AI-powered editor | 📖 Setup Guide |

📦 Installation

Using npx (Recommended)

Tip: Add -y (or --yes) to suppress the interactive prompt npx shows before downloading a package. This prevents AI clients (Claude Desktop, Copilot, Cursor) from hanging waiting for confirmation.

# Test the server
npx -y sfcc-dev-mcp

# Use with your configuration
npx -y sfcc-dev-mcp --dw-json /path/to/your/dw.json

Global Installation

npm install -g sfcc-dev-mcp
sfcc-dev-mcp --dw-json /path/to/your/dw.json

🐛 Debug Mode & Logging

Enable Debug Logging

# Enable debug mode for detailed logging
npx -y sfcc-dev-mcp --debug

# Or with configuration file
npx -y sfcc-dev-mcp --dw-json /path/to/your/dw.json --debug

Log File Locations

The server writes logs to your system's temporary directory:

• macOS: /var/folders/{user-id}/T/sfcc-mcp-logs/
• Linux: /tmp/sfcc-mcp-logs/
• Windows: %TEMP%\sfcc-mcp-logs\

Log Files Created:

• sfcc-mcp-info.log - General application logs and startup messages
• sfcc-mcp-debug.log - Detailed debug information (only when --debug is enabled)
• sfcc-mcp-error.log - Error messages and stack traces
• sfcc-mcp-warn.log - Warning messages

Finding Your Log Directory

// The exact path varies by system - to find yours:
node -e "console.log(require('os').tmpdir() + '/sfcc-mcp-logs')"
