What is Tool Monitoring?
Tool Monitoring tool monitoring tracks and controls how AI agents use their available tools and capabilities—such as web browsers, code execution, file access, or API calls. It ensures agents use tools appropriately and detects suspicious or unauthorized tool usage.

What is Tool Monitoring?
Tool monitoring focuses specifically on the capabilities AI agents use to take actions in the world. Modern AI agents often have access to various tools: web browsers, code interpreters, file systems, email clients, databases, and external APIs. Each tool represents both capability and risk. Tool monitoring provides visibility into how these tools are used, enforces policies on tool usage, and detects anomalous or malicious tool invocations. It's the security boundary between AI decision-making and real-world impact.
How Tool Monitoring Works
Tool monitoring systems intercept and log every tool invocation, capturing what tool was called, with what parameters, and what it returned. Policy engines evaluate each invocation against rules: Is this tool allowed? Are these parameters safe? Is this request rate normal? Machine learning models identify unusual tool usage patterns. For sensitive tools, monitoring may require human approval before execution. All data feeds into dashboards where security teams can review tool usage, investigate incidents, and tune policies. Integration with the agent runtime allows blocking of unauthorized tool calls.
Why Tool Monitoring Matters
Tools are where AI agents affect the real world. An agent's reasoning might be compromised through prompt injection, but without tool access, the damage is limited to generated text. Tool monitoring is the critical control point that prevents compromised reasoning from becoming real-world harm. It's particularly important for high-stakes tools like code execution, financial transactions, or administrative access. Even without attacks, tool monitoring helps ensure agents use their capabilities appropriately and efficiently.
Examples of Tool Monitoring
Monitoring detects that a customer service agent is making unusual numbers of database queries, suggesting potential data harvesting. A policy blocks an agent from executing code that imports networking libraries, preventing data exfiltration. Tool logs reveal that an agent is calling a deprecated API, prompting an update. Anomaly detection notices an agent using its web browser tool to access domains it has never visited before, triggering investigation.
