Are AI Agents Secure?
Agents are as secure as three layers: credentials, tools, and the money path. Secure the weakest one — it's usually the money path.
The credential layer
Scoped keys per agent, rotation, and secret scanning.
A leaked key is spend before it's a headline.
The tool layer
Vet MCP servers and tools — source, permissions, paid calls.
The money layer
Deterministic gates on the money path: caps, allowlists, velocity limits.
Prompts can be injected; rules can't.
FAQ
What's the biggest agent security risk?
Ungoverned spend — it's the least-guarded layer and the most expensive.
Where should I start?
Secret scanning, MCP vetting, and a spend firewall — in that order.
