aport-agent-guardrails vs aport-spec
AI agent authorization tools compared
aport-agent-guardrails applies policy checks to supported AI agent actions through runtime integrations and repository checks. aport-spec defines the Open Agent Passport draft specification and materials for implementing interoperable authorization; it is not a drop-in enforcement service.
aport-agent-guardrails: Authorize AI Agent Actions Before Execution
APort Agent Guardrails checks supported AI agent tool calls against a passport and policy before execution. It provides runtime hooks and plugins for agent frameworks, plus a GitHub Actions repository guard; Node.js 18 or newer is required for the setup wizard.
aport-spec: Define Pre-Action Authorization for AI Agents
aport-spec is the Open Agent Passport (OAP) v1.0 draft, a specification for cryptographically verifiable AI agent credentials and authorization decisions before sensitive actions. It is aimed at platform builders and developers who need a shared runtime trust model for agentic commerce.
