Researchers have developed a new runtime called HCP (Handle-Capability Protocol) designed to enhance the security of AI agent systems that use the Model Context Protocol (MCP) style. This runtime explicitly defines and tests eight security invariants, such as principal binding and data-flow authorization, to prevent attacks. In benchmarks against two other MCP-like systems, HCP successfully blocked all ten modeled attacks while preserving audit evidence, unlike the other systems which allowed various vulnerabilities. AI
