Guardrails for agent security
Top 85.2% on sourcepulse
Invariant Guardrails provides a rule-based layer for securing AI agent systems, particularly those powered by LLMs or MCPs. It acts as a proxy between applications and AI providers, enabling continuous monitoring and steering of agent behavior without invasive code modifications. The system is designed for AI developers and researchers seeking to prevent malicious agent actions and ensure robust system operation.
How It Works
Invariant Guardrails operates by intercepting and analyzing communication between an application and its AI backend. It uses a Python-inspired rule syntax to define conditions that trigger alerts or block actions. These rules can inspect message content, tool calls, and tool outputs, leveraging a standard library of operations for pattern matching and threat detection. The system integrates as a proxy or gateway, automatically evaluating rules before and after AI requests.
