What NLSQL is
NLSQL turns plain-English questions into SQL for analytics and reporting, returning answer templates and, through chat interfaces, answers, charts, and visualizations. People can use Microsoft Teams, Slack, a standalone web app, or web chat without writing SQL. Developers have a REST API, Python client, and an MCP server configurable with Claude, Cursor, OpenClaw, and other compatible agents. Listed database connections include MySQL, Microsoft SQL, PostgreSQL, Amazon Redshift, BigQuery, SQLite, Snowflake, Google Spreadsheets, and Cassandra CQL. Administrators first model the database structure and map KPI calculations to columns. NLSQL returns SQL for the customer’s client to run rather than executing analytical queries itself. Safeguards include parse, policy, literal, SELECT-only, and schema allow-list checks. Deployment can run in a customer’s Azure subscription or through AWS Marketplace; the maker says Azure tenant data remains in the customer environment. Pricing is on request, with a free 30-day trial and no credit card required.
