AI SQL Guardrail API

Build a developer-facing API and SDK that validates LLM-generated SQL before execution. The product would enforce single-statement, read-only, dialect-aware rules and optionally sanitize prompt context, solving the most acute risk discussed.

Pourquoi c'est important

You are trying to let users ask questions in plain language and have an AI generate SQL against a real database. The problem is that the model can be influenced by unsafe user text or by values pulled from the database itself, and the resulting SQL may include writes or multiple statements. Existing framework helpers make the happy path easy, but the safety layer still falls on you. You end up stitching together parser libraries, custom wrappers, and one-off checks because a mistake could damage data or create a security incident.

  • · Conçu pour Engineering teams shipping AI assistants, text-to-SQL features, and internal copilots that query production or analytics databases..
  • · Monétisation la plus probable : SaaS subscription.

Périmètre MVP · 1–2 semaines

Semaine 1
  • Build a Python service that strips markdown fences and normalizes SQL input
  • Integrate a parser library to detect statement boundaries for Postgres and SQLite
  • Implement a policy engine that allows only single SELECT or WITH queries
  • Create a basic Python SDK wrapper for pre-execution validation
  • Publish a landing page with example integrations and a waitlist form
Semaine 2
  • Add JavaScript SDK support for common agent frameworks
  • Implement schema and sample-row sanitization helpers for prompt assembly
  • Add logging dashboard for accepted and rejected queries
  • Create test fixtures for attack cases across multiple SQL dialects
  • Onboard 5 design partners and instrument validation metrics
Fonctions MVP: Dialect-aware SQL parsing and policy enforcement · Single-statement and read-only query validation · Sanitization of schema and sample-row prompt context · SDKs for Python and JavaScript AI frameworks · Execution audit logs and policy alerts

Différenciation

Solutions existantes
LangChain legacy SQL chainRegex-based SQL validatorsCustom agent implementations
Notre angle
There is a gap for a plug-in security layer that sits between LLMs and databases, enforces deterministic SQL policy, and reduces prompt-injection risk without forcing teams to rebuild their application architecture.

Pourquoi cela pourrait échouer

Auto-contre-argument — le signal de confiance le plus important

  1. 1Teams may prefer to use open-source parser libraries directly and avoid another paid infrastructure dependency.
  2. 2Native framework improvements could close enough of the gap that standalone guardrails feel redundant.
  3. 3If the validator blocks legitimate queries too often, developers will bypass it to preserve product velocity.

Résumé des preuves

Comment l'IA a synthétisé cet aperçu — pas de citations textuelles

The discussion repeatedly focused on unsafe SQL reaching execution without deterministic checks. Several comments separated prompt injection risks from SQL policy risks and emphasized that parser-based validation is more robust than keyword filters. The strongest signal is that contributors are already proposing custom wrappers and parser libraries, indicating clear pain and active effort to solve it.
