Which integrations are available for this server?

Provides async [LangChain](/mcp/servers/integrations/langchain) integration for building RAG (Retrieval-Augmented Generation) pipelines with semantic search and LLM-powered responses Offers a premium glassmorphism UI for interacting with the LiveKit documentation search system, featuring real-time chat, animations, and source attribution

💬 LiveKit RAG Assistant v2.0

Enterprise-grade AI semantic search + real-time web integration for LiveKit documentation

🎯 Features

Dual Search: Pinecone docs (3,000+ vectors) + Tavily real-time web
Standard MCP: Async LangChain with Model Context Protocol
Ultra-Fast: Groq LLM (llama-3.3-70b) sub-5s responses
Premium UI: Glassmorphism design with 60+ animations
Source Attribution: Full transparency on every answer

🚀 Quick Start

# Setup conda create -n langmcp python=3.12 conda activate langmcp pip install -r requirements.txt # Configure .env GROQ_API_KEY=your_key TAVILY_API_KEY=your_key PINECONE_API_KEY=your_key PINECONE_INDEX_NAME=livekit-docs # Terminal 1: Start MCP Server python mcp_server_standard.py # Terminal 2: Start UI streamlit run app.py

🏗️ Architecture

Streamlit (app.py) → MCP Server → Dual Search: ├─ Pinecone: Semantic search on embeddings (384-dim) └─ Tavily: Real-time web results ↓ Groq LLM (2048 tokens, temp 0.3) → Response + Sources

🔧 Tech Stack

Layer	Tech	Purpose
Frontend	Streamlit	Premium glassmorphism UI
Backend	MCP Standard	Async subprocess
LLM	Groq API	Ultra-fast inference
Embeddings	HuggingFace	all-MiniLM-L6-v2 (384-dim)
Vector DB	Pinecone	Serverless similarity search
Web Search	Tavily	Real-time internet results

🚨 Troubleshooting

Issue	Solution
No results	Try web mode or different keywords
MCP not found	Start mcp_server_standard.py in Terminal 1
Slow first response	Normal (15-20s) - model initializes once
API errors	Verify all keys in .env file
