Get disk usage breakdown across all accounts on the server
AI agents call whm_disk_usage to retrieve information from ItchWHMMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries disk usage metrics across accounts without modifying, deleting, or executing anything. It is a straightforward read operation that retrieves monitoring data. The blast radius of misuse is minimal: an agent could gather information about server disk capacity and allocation, which is helpful for system administration but poses no destructive or financial risk.
From the tool's definition Tool name includes 'usage' and description states 'Get disk usage breakdown' — a retrieval operation with no modification or execution
Attacks that exploit this kind of access
Get disk usage breakdown across all accounts on the server. It is categorised as a Read tool in the ItchWHMMCP MCP Server, which means it retrieves data without modifying state.
Register the ItchWHM MCP server in PolicyLayer and add a rule for whm_disk_usage: 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 ItchWHMMCP. Nothing to install.
whm_disk_usage 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 whm_disk_usage 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 whm_disk_usage. 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.
whm_disk_usage is provided by the ItchWHM MCP server (manofsadness/itchwhmmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
