Show HN: ClawMoat – Open-source runtime security for AI agents (zero deps, <1ms) (github.com)

ClawMoat has been introduced as an open-source runtime security solution specifically designed for AI agents, providing crucial protection against threats like prompt injection, tool misuse, and data exfiltration. Built to integrate seamlessly with frameworks such as LangChain and OpenAI Agents, ClawMoat offers sub-millisecond scanning capabilities without any external dependencies, making it lightweight and efficient. Key features include advanced prompt injection detection, secret and Personally Identifiable Information (PII) scanning, and a defined policy engine, all essential to safeguarding AI agents that have significant access to sensitive functionalities like web browsing and file management. The significance of ClawMoat lies in addressing notable security vulnerabilities that AI agents face, particularly as their capabilities expand. Based on research from Anthropic regarding "Agentic Misalignment," ClawMoat incorporates specialized detectors for identifying insider threats, behavioral anomalies, and unauthorized data sharing. It also aligns with the OWASP Top 10 risks for Agentic AI, providing comprehensive coverage against common security concerns in this rapidly evolving field. The tool not only enhances AI safety but also encourages collaboration within the developer community by inviting security researchers to test its defenses, fostering a proactive approach to security in AI development.
