Get CPU, memory, and disk metrics from the system
AI agents call get_system_metrics to retrieve information from Log Analyzer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves system performance information for monitoring or diagnostic purposes. It performs a query-like operation with no side effects, no code execution, and no data modification. The blast radius of misuse is minimal: an agent could gather system telemetry, but cannot alter system state or trigger actions.
From the tool's definition Tool name and description indicate it 'Get[s] CPU, memory, and disk metrics from the system' — a retrieval operation with no modification or execution of external code.
Attacks that exploit this kind of access
Get CPU, memory, and disk metrics from the system. It is categorised as a Read tool in the Log Analyzer MCP Server, which means it retrieves data without modifying state.
Register the Log Analyzer MCP server in PolicyLayer and add a rule for get_system_metrics: 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 Log Analyzer. Nothing to install.
get_system_metrics 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 get_system_metrics 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 get_system_metrics. 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.
get_system_metrics is provided by the Log Analyzer MCP server (yufeizhou666/my_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
