🚀 Roblox Documentation MCP Server with RAG Support

MCP server with RAG support for intelligent Roblox documentation search and retrieval

This MCP server enables AI agents to intelligently search and retrieve Roblox documentation through semantic search and vector embeddings. It provides natural language access to the complete Roblox Creator Documentation.

🎯 What This Does

Enable AI agents to:

  • 🔍 Semantic Search: Find relevant documentation through natural language queries
  • 📚 API References: Get specific details about Roblox classes, methods, and properties
  • 🎓 Tutorial Discovery: Locate step-by-step guides and learning materials
  • 💡 Code Examples: Find relevant code snippets and demonstrations
  • 🏷️ Smart Filtering: Search by content type, difficulty, or topic

🏗️ Architecture

✨ Key Features

Feature AreaDescriptionImplementation
🔍 Semantic SearchNatural language queries across all Roblox documentationChromaDB + OpenAI embeddings
📖 Content ProcessingProcesses markdown guides, tutorials, and YAML API referencesmarkdown-it + yaml parsers
🔄 Auto-UpdatesKeeps documentation current via git pull from official repositorysimple-git integration
🏷️ Smart ClassificationAutomatically categorizes content (guides, tutorials, API references)Metadata extraction + classification
⚡ PerformanceFast semantic search with caching and optimized vector storageRedis caching + ChromaDB
🔒 Production ReadyBuilt on proven MCP template with comprehensive error handlingFull TypeScript + Zod validation

🚀 Quick Start

Prerequisites

  • Node.js 20+
  • ChromaDB server (Docker recommended)
  • OpenAI API key

Installation

# Clone the repository git clone https://github.com/christopher-buss/roblox-docs-mcp.git cd roblox-docs-mcp # Install dependencies npm install # Set up environment variables cp .env.example .env # Edit .env with your OpenAI API key and ChromaDB settings # Start ChromaDB (using Docker) docker run -p 8000:8000 chromadb/chroma # Build the project npm run build

Environment Configuration

Create a .env file with the following variables:

# OpenAI Configuration OPENAI_API_KEY=your_openai_api_key # ChromaDB Configuration CHROMA_DB_URL=http://localhost:8000 CHROMA_DB_COLLECTION=roblox-docs # Roblox Documentation ROBLOX_DOCS_REPO_URL=https://github.com/Roblox/creator-docs.git ROBLOX_DOCS_LOCAL_PATH=./data/roblox-docs ROBLOX_DOCS_UPDATE_INTERVAL=24 # Embedding Configuration EMBEDDING_MODEL=text-embedding-3-large MAX_CHUNK_SIZE=1000 CHUNK_OVERLAP=200 # Optional Redis Cache REDIS_URL=redis://localhost:6379

Running the Server

# Start MCP server (stdio transport) npm run start:stdio # Start MCP server (HTTP transport) npm run start:http # Update documentation repository npm run docs:update # Launch MCP inspector for debugging npm run inspector

🔧 Development

Architecture Overview

This project extends the cyanheads/mcp-ts-template with Roblox-specific capabilities:

  • Git Service: Manages the Roblox creator-docs repository
  • Content Processor: Parses markdown and YAML files
  • RAG Service: Handles embeddings and semantic search
  • MCP Tools: Provides search and retrieval capabilities

Adding New Features

  1. New Tools: Follow the template pattern in src/mcp-server/tools/
  2. Content Processing: Extend processors in src/services/content-processor/
  3. RAG Enhancements: Modify search logic in src/services/roblox-rag/

Development Commands

npm run build # Build TypeScript npm run format # Format code with Prettier npm run docs:generate # Generate TypeDoc documentation npm run tree # Generate project structure npm run depcheck # Check for unused dependencies

🧪 Testing

# Test individual components npm run test:unit # Test MCP tools end-to-end npm run test:integration # Test RAG functionality npm run test:rag

📊 Performance

  • Search Latency: < 500ms for semantic queries
  • Memory Usage: < 2GB RAM for full documentation index
  • Document Processing: 100+ docs/minute ingestion rate
  • Cache Hit Rate: > 80% for repeated queries
