Claude MCP

A multi-agent AI assistant powered by Gemini LLM using the ReAct pattern to orchestrate specialized agents through Model Context Protocol (MCP). Features a LangGraph supervisor with streaming Streamlit and Gradio UIs.

✨ Features

• ReAct-based supervisor – dynamically routes queries to specialized agents
• 5 Specialized Agents – crypto, stocks, portfolio tracking, RAG document Q&A, web search
• Real-time streaming – see AI reasoning steps as they happen
• Document upload – chat with PDFs, TXT, and DOCX files
• Cloud integration – ChromaDB Cloud for vectors, Google Cloud SQL for portfolio data
• Docker support – containerized MCP servers

🛠️ Tech Stack

• AI/LLM: Google Gemini 2.5 Pro, LangChain, LangGraph
• UI: Streamlit (main), Gradio 5.0+ (for demos)
• Agent Protocol: FastMCP (Model Context Protocol)
• Databases: ChromaDB Cloud (vectors), Google Cloud SQL (PostgreSQL)
• APIs: Alpha Vantage, CoinGecko, DuckDuckGo
• DevOps: Docker, Docker Compose

⚙️ How It Works

The ReAct supervisor uses a reasoning loop (max 5 steps):

1. Think – Analyze query and determine needed information
2. Act – Call appropriate agent(s)
3. Observe – Process agent responses
4. Repeat – Continue until sufficient information gathered
5. Synthesize – Generate final answer
