Action Summary

The Agent Security Harness is a comprehensive testing framework designed to evaluate the security and decision-making integrity of agent-based systems, such as those utilizing MCP, A2A, L402, and x402 protocols. It automates the detection of vulnerabilities in wire protocols, operational governance, and decision-making processes by simulating adversarial scenarios, including protocol exploits, capability escalations, and policy violations. This tool provides over 400 prebuilt security tests, enabling organizations to proactively identify and mitigate risks in agent behavior and governance.
