SFCC class names or method signatures - Custom attribute names or system object structures - Current best practices or security guidelines - Available hook endpoints or extension points - Recent system errors or log patterns ## 🔐 Tool Availability Some tools require specific SFCC credentials: - **Documentation & Best Practices**: Always available - **Log Analysis**: Requires SFCC instance credentials (hostname, username, password) - **System Objects & Code Versions**: Requires OCAPI credentials (clientId, clientSecret) If a tool isn't available, the MCP server will provide clear error messages about what credentials are needed. ## 💡 Pro Tips 1. **Start Broad, Then Narrow**: Use search tools first, then get detailed information 2. **Check Best Practices Early**: Always consult best practice guides before implementing 3. **Use Real Data**: Query actual system objects rather than assuming structure 4. **Debug with Logs**: Use log analysis tools for troubleshooting real issues 5. **Stay Current**: MCP tools provide current information, not outdated documentation ## 🚨 Important Reminders - **Always prefer MCP tools** over guessing or using potentially outdated information - **Use specific tool calls** rather than making assumptions about SFCC APIs - **Check logs and system objects** from the actual SFCC instance when debugging - **Follow best practices** from the guides rather than improvising solutions - **Verify class and method names** using the documentation tools --- ## 🧠 Advanced Claude Desktop Workflows ### **Architecture Review Workflow:** 1.
