Production-Style Agentic Chatbot with Tool Calling & RAG
Cymbal Air Assistant is a refactored version of the original Google Cloud Cymbal Air Toolbox demo, rebuilt into a modern, modular agentic chatbot system.
Replaces the original Google Toolbox, AlloyDB, and Gemini stack with FastMCP, PostgreSQL + pgvector, and OpenAI/GROQ models. Uses LangGraph to structure the agent into clear, testable nodes with explicit control flow for tool usage, authentication, and booking validation.
