IntentProbe: The First Activation-Probe-Based MCP/Tool Scanner. It Reads the Model's Brain, Not Just the Text.
A new tool called IntentProbe has been released, offering a novel approach to detecting malicious AI tool descriptions. Unlike traditional text-based scanners or LLM-as-judge methods, IntentProbe analyzes the internal activation states of a frozen model when processing tool descriptions. This method aims to identify hidden intents like credential access or data exfiltration, which can be masked by seemingly innocuous vocabulary. AI
IMPACT Enhances AI agent security by providing a novel method to detect malicious tool descriptions that evade traditional text-based analysis.
