AgentGuard is an LLM-as-a-judge HTTP proxy designed to secure AI agents in production environments. Inspired by the “CrabTrap” concept, it acts as an intermediary, validating and sanitizing inputs and outputs of AI agents to prevent malicious attacks, data leaks, or unintended behaviors. This protects against prompt injection, data exfiltration, and ensures agents operate within defined ethical and functional boundaries, similar to how a proxy can manage network traffic.
