Checks system health (disk space, memory) and identifies potential
AI agents call scan_system_health to retrieve information from Virtualbox MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and reports system metrics (disk space, memory usage) and diagnostic information. These are read-only queries with no side effects on the system state. The verb 'scan' in the context of health checks indicates monitoring and reporting rather than execution, modification, or destruction of resources.
From the tool's definition Tool name is 'scan_system_health' and description indicates it 'Checks system health (disk space, memory) and identifies potential...' — uses verbs like 'Checks' and 'identifies' which are read-only operations that query system state without modification.
Attacks that exploit this kind of access
Checks system health (disk space, memory) and identifies potential. It is categorised as a Read tool in the Virtualbox MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Virtualbox MCP Server MCP server in PolicyLayer and add a rule for scan_system_health: 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 Virtualbox MCP Server. Nothing to install.
scan_system_health 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 scan_system_health 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 scan_system_health. 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.
scan_system_health is provided by the Virtualbox MCP Server MCP server (usemanusai/virtualbox-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
