What Is SeDQL?

SeDQL is a command-line tool that generates LLM-ready schema context from your database.

It reads your database schema and exports a clean, structured JSON file with business names, relationships, PII flags, and validation rules. No cloud. No API keys. No over-engineering.

Reads Your Schema

Tables, columns, foreign keys, constraints.

Maps to Business Names

users -> Customers, orders -> Orders.

Exports JSON

Ready for any LLM, agent, or RAG pipeline.

How It Works

Three simple steps. No complicated setup. No cloud.

Install

One command. No dependencies. Works on any system.

pip install sedql-cli

Initialize

Point it at your database. It reads your schema automatically.

sedql init --db "postgresql://..."

Query or Export

Ask questions with templates, or export JSON for your AI.

sedql export --output context.json
