The Agent Security Harness is a testing tool designed for evaluating the security and integrity of payment agent protocols, with a specific focus on identifying manipulative behaviors even when agents are properly authenticated and authorized. It features 603 executable security tests across 44 modules that cover a wide range of protocols, including MCP, A2A, and Visa/Mastercard specific tests, along with mechanisms for detailed reporting on test results. The tool supports a taxonomy-driven evidence approach to classify and validate security claims, enhancing confidence in security assessments carried out on agentic payment systems.
