Comprehensive health check: CPU, RAM, Disk space and Inode usage
AI agents call plesk_server_health_detailed to retrieve information from Plesk 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 on server health metrics (CPU, RAM, Disk, Inode usage) without modifying any system state, executing commands, or triggering external operations. It is a passive read/monitoring operation. The low severity reflects that unauthorized access to performance metrics poses minimal risk compared to tools that modify system configuration or data.
From the tool's definition Tool name and description indicate retrieval of server metrics: 'Comprehensive health check: CPU, RAM, Disk space and Inode usage' — these are queries of system state with no modification or side effects.
Attacks that exploit this kind of access
Comprehensive health check: CPU, RAM, Disk space and Inode usage. It is categorised as a Read tool in the Plesk MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Plesk MCP Server MCP server in PolicyLayer and add a rule for plesk_server_health_detailed: 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 Plesk MCP Server. Nothing to install.
plesk_server_health_detailed 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 plesk_server_health_detailed 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 plesk_server_health_detailed. 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.
plesk_server_health_detailed is provided by the Plesk MCP Server MCP server (klan1/plesk-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
