The App Store Nightmare: Why AI MCP Stores Are a Trap
The app store nightmare is here – and you’re already in it. AI “helpers” (agents) powered by MCP (a system that lets AI use other tools) can act on your behalf without you seeing it. Host Lieuwe Jan Koning and Rob Maas (Field CTO, ON2IT) show how this “AI convenience” hides an unregulated app store where one bad update can cause a breach. Real cases include the Postmark MCP backdoor that copied emails, Shadow Escape that stole data from a hidden prompt, and kubectl mistakes that wiped servers.
What you’ll learn:
• How The app store nightmare turns AI helpers into new attack paths
• How a tricked document can make AI run silent commands
• Why Zero Trust is your last line of defense
• How to fight back: inventory, least privilege, whitelist-only tools
You thought the AI app store worked for you. It doesn’t – until you take control.

Episode details
From ON2IT HQ, Lieuwe Jan Koning and Rob Maas explain, in plain language, how fast companies are connecting AI to files, chats, and systems through MCP servers. There’s no real gatekeeper yet. No strong vetting. Just many “AI tools” asking for broad permissions. That creates a new supply chain risk where a single update – or a sneaky document – can quietly steal data or even erase systems.
ON2IT’s Zero Trust plan is clear and practical: keep an inventory of every AI tool, limit access to only what each task needs, require human approval for risky actions, and whitelist the few tools you truly trust. Log versions and updates like third-party code. Set token/usage limits to reduce tool sprawl. AI isn’t slowing down – so set the rules now and make the app store work for you, not against you.
