SummaryThe paper demonstrates how an authenticated MCP tool can exfiltrate confidential data despite signature verification and runtime controls. It proposes germline execution, which forks each invocation from a data-free process and restricts information available to that invocation, then evaluates the method against attack runs and baseline defences.
Why it mattersProvides comparative attack results, explicit security assumptions, and latency measurements useful for assessing protections around third-party agent tools.
