🏗️ Architecture Overview

This is a dual-component system bridging Roblox Studio with AI assistants:

Key Components:

• 🧠 MCP Server (Node.js/TypeScript) - Exposes 15 tools via stdio for AI integration
• 🔗 HTTP Bridge - Request/response queue on localhost:3002 with 30s timeouts
• 🎮 Studio Plugin (Luau) - Polls every 500ms, executes Studio API calls, handles errors
• 📊 Smart Caching - Efficient data transfer with intelligent response limiting

🛠️ 15 Powerful AI Tools

📁 File System Tools

• get_file_tree - Complete project hierarchy with scripts, models, folders
• get_file_content - Extract source code from any script
• search_files - Find files by name, type, or content patterns
• get_file_properties - Script metadata, parent/child relationships

🎯 Studio Context Tools

• get_place_info - Place ID, name, game settings, workspace info
• get_services - All Roblox services and their child counts
• get_selection - Currently selected objects in Studio Explorer
