arXiv paper proposes black-box detection of indirect prompt injection flaws in MCP servers
A new arXiv preprint describes an approach for finding indirect prompt injection vulnerabilities in MCP servers without needing system access or live interaction. The method works from descriptions alone, targeting third-party audits of closed-source, remotely hosted, or commercially gated software where conventional analysis is not possible. The authors position it as a way to assess critical systems that analysts cannot directly inspect or probe.
