Why it matters

MCP is becoming the control plane for autonomous AI agents while lacking built-in identity and access controls, expanding the enterprise attack surface through prompt injection, tool poisoning, and data exfiltration that traditional controls fail to catch.

An analysis piece synthesizing MCP (Model Context Protocol) security risks for CISOs, drawing on a Darktrace blog and an arXiv paper (arXiv:2511.20920) by Errico, Ngiam, and Sojan. It categorizes threats such as content-injection attackers embedding malicious instructions into agent-consumed data, supply-chain attackers distributing compromised MCP servers, and over-privileged agents enabling data-driven exfiltration, tool poisoning, and cross-system privilege escalation, and proposes controls including scoped per-user authentication, sandboxing, provenance tracking, DLP, and centralized governance.
