Most enterprises assume their Zero Trust architecture covers their AI agents. It doesn't. Hosts Tova Dvorin and Adrian Culley break down why zero trust breaks against the Model Context Protocol (MCP)—and why "verified" no longer means "safe." They unpack trust decay, the WhatsApp and GitHub MCP exploits, rug-pull tool poisoning, CVE-2025-49596, and the rise of "zero standing trust," then close with three moves for CISOs this quarter: inventory your MCP estate, mandate authentication, and validate your controls.

A security researcher introduced a malicious MCP server into an environment that already had a legitimate WhatsApp integration—and watched it silently expose message history without any user approval. The technique is called a rug pull. The server advertised one behavior at installation. On second usage, it switched to something else entirely. The approval was real. The thing you approved was not. This is what trust decay looks like in practice—and it passes every classical security check.

In a multi-agent AI workflow, one agent's output becomes the next agent's input. That's the design. It's also the attack surface. Researchers have demonstrated that a single poisoned output can cascade across an entire pipeline — triggering unauthorized behavior, data exfiltration, and control flow hijacking across chained MCP processes. The attack class is called toxic flows. And every one of them passes classical zero trust checks.
