sauceql
A JSON-schema-defined, agent-safe read-only SQL query DSL and compiler.
Define your tables (columns, relations, and safety restrictions like required
filters, max limit, allowed operators) in a JSON file validated against
db_schema.json. Agents submit queries as JSON matching query_schema.json -
a structured AST (no raw SQL strings), which is validated against your table
definitions and compiled to parameterized PostgreSQL SQL.
Install
pip install sauceql
Usage
from sauceql import SauceEngine
engine = SauceEngine(tables_path="my_tables.json")
query = {
"from": "orders",
"select": ["orders.id", "orders.status"],
"where": {"column": "status", "op": "eq", "value": "paid"},
"order_by": [{"column": "created_at", "dir": "desc"}],
"limit": 20,
}
sql, params = engine.toPGSQL(query, context={"tenant_id": "acme-corp"})
See examples/demo.py and examples/example_tables.json for a full worked
example with joins, aggregates, and tenant-scoping restrictions.
