Nl2sql Python Packages

schemagate

Text-to-SQL access control: schema selection that gives the LLM only the tables the caller is allowed to read. Row-level-security-aware table pruning for LangChain, MCP and any SQL agent. Postgres, Oracle, MySQL, SQL Server. 75% fewer prompt tokens.

agami-core

The trust layer between AI and your data. Turns your database schema - messy joins, undocumented tables, into a governed semantic model so AI answers with correct SQL and a receipt on every answer. Run it locally, or self-host a shared team server with Docker.

asksql

Maintained, security-patched drop-in successor to Vanna (archived). Text-to-SQL with LLMs: pip install asksql, keep import vanna.

nl2sql-adapter-sdk

Ask your database questions in English. The model emits a typed query plan, never SQL text - validated against the real schema and the caller's role before any SQL is generated.

nl2sql-engine

Ask your database questions in English. The model emits a typed query plan, never SQL text - validated against the real schema and the caller's role before any SQL is generated.

nl2sql-api

Ask your database questions in English. The model emits a typed query plan, never SQL text - validated against the real schema and the caller's role before any SQL is generated.

Open source natural language to SQL (NL2SQL) engine with schema validation and an MCP server for Claude and Cursor

cognidb

CogniDB is a Python-powered Natural Language to SQL interface that enables users to query databases like MySQL, PostgreSQL, MongoDB, and AWS RDS using plain English. It parses questions, understands schema, generates safe SQL, and returns results, empowering non-technical users to gain database insights without writing SQL.

ashiq
