Agent Tool Permission Design: Least Privilege for Autonomous Systems
An agent with broad tool access has a broad blast radius when it goes wrong. Designing tool permissions following least-privilege principles is the single most important agent safety control.
10 min · Reviewed 2026
The premise
Tool permission design is the agent equivalent of IAM — get it wrong and the blast radius is enormous.
What AI does well here
Scope tool capabilities to the minimum required for each task
Use ephemeral credentials with short TTLs scoped to the agent's task
Maintain audit logs of every tool invocation with the prompt context that triggered it
What AI cannot do
Substitute for understanding what the agent is actually authorized to do
Replace the human review of high-stakes actions
Make permissions prevent every misuse — they reduce risk, they don't eliminate it
