🤖 NeuroBot: Agentic RAG Research Assistant

NeuroBot is a production-grade conversational AI system designed for deep technical document analysis and research. It utilizes LangGraph for sophisticated multi-step orchestration and the Model Context Protocol (MCP) for a modular, scalable tool architecture.

🚀 Core Features

• Agentic Orchestration: Uses LangGraph to implement Corrective RAG (CRAG) and self-correction loops.
• Intelligent Retrieval: Combines local PDF indexing (FAISS) with real-time ArXiv and DuckDuckGo web search recovery.
• Automated Quality Audit: Integrated RAGAS evaluation to measure Faithfulness and Answer Relevancy in real-time.
• Session Persistence: Robust multi-tenant session management using SQLite checkpointing.
• Modular Tooling: Fully decoupled tool execution via local and remote MCP servers.

🛠️ Technology Stack

• Brain: LangGraph, LangChain
• LLM: Groq (Llama 3.3 70B)
• Vector Search: FAISS
• Embeddings: HuggingFace (all-MiniLM-L6-v2)
• Interface: Streamlit (Dashboard), FastAPI (REST API)
• Persistence: SQLite
