Text-to-SQL AI Agent
Built at PraxiLabs: an agent that converts natural language into SQL against dynamic database schemas with 95%+ query accuracy, wrapped in secure query execution, visualisation, authentication and role-based access control with full permission enforcement.
Non-technical teams needed answers from a database without waiting on an analyst.
A LangGraph agent inspects the live schema, plans a query, validates it against the caller’s permissions, then executes it in a sandboxed read-only session. Results are returned as tables or Chart.js visualisations. Every request is scoped by role, so the agent can never reach data the user is not authorised to see.
Tools: FastAPI, LangGraph, Chroma Server, Chart.js, custom tools.
