OpenClaw Guardrails is a free Chrome add-on designed to enhance the security of autonomous AI agents by preventing prompt injection attacks. The tool actively scans web pages to detect various threats, including instruction overrides and encoding attacks, providing real-time visual warnings. This ensures that users can maintain control over their agents' actions, mitigating the risk of unauthorized operations.

In addition to threat detection, OpenClaw Guardrails features agent action blocking to hide dangerous buttons and offers customizable site controls for whitelisting and blocklisting domains. Users have access to a local scan history for auditing, and the tool operates entirely on-device, ensuring that no data leaves the browser. With configurable severity thresholds, users can tailor the security settings to their individual risk tolerance.
