AI Agent Security: Move Access Controls Before Tool Selection

By PulseAugur Editorial · [1 sources] ·

This article argues that access controls for AI agents should be implemented before the model selects a tool, rather than within the tool handler. The author explains that current methods, which check permissions after a tool has been selected and arguments constructed, are too late. This allows untrusted input to influence tool selection, creating a security vulnerability. The proposed solution involves resolving the caller's identity, mapping it to an explicit allowlist of tools, and only exposing those allowed tools to the model, thereby preventing the model from selecting unauthorized capabilities.
