AI agents call run_system_health_check to retrieve information from Arch Linux without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs read-only diagnostics and monitoring — checking disk space, failed services, updates, orphan packages, and news. It does not modify, execute, delete, or commit any financial operations. The medium severity reflects that it runs on the host OS and reads potentially sensitive system state information, but has no write or destructive side effects.
From the tool's definition 'Run a comprehensive system health check', 'Integrates multiple diagnostics to provide a complete overview of system status', 'Only works on Arch Linux'
Documented attack patterns abuse exactly the kind of access run_system_health_check gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Arch Linux, and nothing reaches the server without passing your rules. This is the rule we recommend for run_system_health_check:
{
"version": "1",
"default": "deny",
"tools": {
"run_system_health_check": {}
}
}run_system_health_check is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

[MONITORING] Run a comprehensive system health check. Integrates multiple diagnostics to provide a complete overview of system status, including disk space, failed services, updates, orphan packages, and more. Only works on Arch Linux. Comprehensive check: Updates available, disk space, failed services, database freshness, orphans, and critical news. It is categorised as a Read tool in the Arch Linux MCP Server, which means it retrieves data without modifying state.
Register the Arch Linux MCP server in PolicyLayer and add a rule for run_system_health_check: 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 Arch Linux. Nothing to install.
run_system_health_check 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 run_system_health_check 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 run_system_health_check. 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.
run_system_health_check is provided by the Arch Linux MCP server (nihalxkumar/arch-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
