How to validate AI generated SQL with your AI

Connect this MCP to your agent to catch broken queries before they run. Your AI checks the syntax locally so you don't crash your database.

Short answer

How can I stop my AI from writing broken SQL?

Your AI uses local AST parsing to check the structure of a query against standard SQL rules. This catches typos and syntax errors before the code hits your production environment. You'll see exactly where the logic breaks.

The results.

Where every error lands.

The AI handles the heavy lifting of parsing, leaving you to handle the logic.

SYNTAX

Caught typos

The AI identifies missing commas, unclosed parentheses, or misspelled keywords. You get a clean report of what's broken.

STRUCTURE

Valid logic

The parser checks if the query follows proper SQL grammar. This prevents the agent from sending malformed statements.

HUMAN

Manual review

If the syntax is perfect but the query returns no data, you decide if the logic is actually correct. The AI only checks if the code is readable by the engine.

FIXED

Corrected code

The AI uses the error feedback to rewrite the query. You receive a version that is ready to execute.

The workflow

What your AI does when a query is written.

The AI acts as a gatekeeper between the prompt and your database.

  1. Analyze structure

    The agent takes the raw text and builds an Abstract Syntax Tree to understand the query's shape.

    validate_sql

  2. Identify errors

    The tool scans the tree for any violations of SQL syntax rules.

    validate_sql

  3. Report failures

    The AI identifies the exact line and character where the syntax fails.

    validate_sql

  4. Suggest fixes

    The agent uses the error details to propose a corrected version of the query.

FAQ

How this task behaves.

  • 01

    Does this tool actually run the query on my database?

    No. This tool only parses the text to check for syntax errors. It never executes code against your data.

  • 02

    Can the AI fix my database schema?

    No. The AI can only suggest changes to the SQL text itself. It has no permission to modify your tables or data.

  • 03

    What kind of SQL does it support?

    It uses local AST parsing to validate standard SQL syntax patterns.

  • 04

    Will it catch logical errors?

    No. It catches syntax errors, like a missing bracket. It won't know if you're joining the wrong tables or using the wrong filter logic.

  • 05

    Do I need to give it my database password?

    No. Because the validation happens via local parsing, your agent doesn't need a connection to your actual database to check the syntax.
