Traditional security relies on a simple principle:
Least Privilege.
Users receive only the permissions required to perform their tasks.
Nothing more.
The same principle is becoming critical for AI agents.
Modern agents increasingly have access to:
• APIs
• databases
• internal tools
• external services
The challenge isn't whether they can access these resources.
The challenge is whether they should.
Humans naturally question permissions.
AI agents often optimize for execution.
If a tool is available and an instruction appears valid, an agent may proceed without considering whether the action is necessary.
That's why excessive permissions become dangerous in agentic systems.
Security is no longer just about protecting infrastructure.
It's about managing behavior.
As agents become more autonomous, least privilege will become one of the most important safeguards in AI security.
This is one of the reasons we're building Crucible.
Pytest for AI agents.
