WHEN AI AGENTS USE THIS TOOL

AI agents call explain_sql_statement to perform operations in Neon. While the risk category is not fully classified, applying a rate limit gives you visibility into how often the tool is called and prevents unexpected bursts of activity from autonomous agents.

WHY ENFORCE A POLICY ON EXPLAIN_SQL_STATEMENT

Applying a policy to explain_sql_statement gives you an audit trail of every call an AI agent makes. Even for low-risk tools, visibility into agent behaviour helps you debug issues, optimise workflows, and maintain compliance with your organisation's security requirements.

RECOMMENDED POLICY

Apply a rate limit to control usage and monitor for unexpected behaviour.

neon.yaml 
tools:
  explain_sql_statement:
    rules:
      - action: allow
        rate_limit:
          max: 60
          window: 60
