List loaded drivers/modules (lsmod or driverquery).
AI agents call list_kernel_modules to retrieve information from Systems Manager without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs information retrieval about currently loaded kernel modules/drivers. The operations lsmod (Linux) and driverquery (Windows) are standard diagnostic commands that query system state and return data. No side effects, modifications, or external operations are triggered.
From the tool's definition Tool name 'list_kernel_modules' and description 'List loaded drivers/modules (lsmod or driverquery)' indicate a read-only query operation that retrieves system state without modification.
Attacks that exploit this kind of access
List loaded drivers/modules (lsmod or driverquery). It is categorised as a Read tool in the Systems Manager MCP Server, which means it retrieves data without modifying state.
Register the Systems Manager MCP server in PolicyLayer and add a rule for list_kernel_modules: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Systems Manager. Nothing to install.
list_kernel_modules is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_kernel_modules rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_kernel_modules. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_kernel_modules is provided by the Systems Manager MCP server (knuckles-team/systems-manager). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
