Rate-Limited Defense: Safeguarding PostgreSQL from Rogue AI Agents

As AI agents increasingly integrate with production systems, uncontrolled database access poses a critical risk—a hallucinated query can delete entire tables before intervention is possible. Rate limiting on MCP tool calls acts as a circuit breaker, giving operators time to catch and stop runaway agents before they cause irreversible damage. This approach represents a practical security pattern for enterprises deploying AI agents in sensitive environments.
