What is a tool allowlist for an artificial intelligence agent?
Definition
A tool allowlist limits an agent to known capabilities instead of letting it call any discovered command or service. Entries can be further scoped by operation, resource, identity and environment so access matches the task.
Allowlists reduce attack surface and make authorization easier to audit, but inclusion alone does not make a tool safe. Each call still needs input validation, bounded credentials and checks on the resulting side effects.

It blocks access to tools and operations that were not explicitly approved for the workflow.
Is an allowed tool automatically safe?
No. The system must still validate arguments, apply scoped permissions and inspect consequential results.
