Klent

Klent is an AI agent guardrail system that intercepts tool calls made by AI agents, allowing developers to allow, deny, modify, steer, or pause each call. It solves the problem of uncontrolled, potentially destructive actions by AI agents, such as unintended database writes or refunds. The product targets developers and IT teams in companies of various sizes, particularly those using AI agents in production. It is positioned as a drop-in solution that works with existing tools and agent frameworks, offering a two-line SDK and a full audit trail.
