Roblox Documentation MCP Server

🚀 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 Area	Description	Implementation
🔍 Semantic Search	Natural language queries across all Roblox documentation	ChromaDB + OpenAI embeddings
📖 Content Processing	Processes markdown guides, tutorials, and YAML API references	markdown-it + yaml parsers
🔄 Auto-Updates	Keeps documentation current via git pull from official repository	simple-git integration
🏷️ Smart Classification	Automatically categorizes content (guides, tutorials, API references)	Metadata extraction + classification
⚡ Performance	Fast semantic search with caching and optimized vector storage	Redis caching + ChromaDB
🔒 Production Ready	Built on proven MCP template with comprehensive error handling	Full 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

New Tools: Follow the template pattern in src/mcp-server/tools/
Content Processing: Extend processors in src/services/content-processor/
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
