Policy And Guardrail Rule Definition And Enforcement

Security scanner for AI agents, MCP servers and agent skills.

Unique: Implements rule-based policy enforcement for MCP traffic with support for stateful policies (preventing toxic tool chains across multiple calls) and built-in policy templates; integrates with proxy mode for real-time enforcement

vs others: Provides declarative policy definition and enforcement without requiring code changes to agents or MCP servers, enabling security policies to be deployed and updated independently

OpenAI Guardrails: A TypeScript framework for building safe and reliable AI systems

Unique: Uses a declarative YAML/JSON schema approach for guardrail definition rather than imperative code, enabling non-developers to modify safety policies and providing version-controllable policy artifacts separate from application code

vs others: More accessible than hand-coded validation logic and more flexible than hard-coded safety checks, allowing policy iteration without code deployment cycles
