WHAT IT DOES

What disk_usage_report does on Mcp Hands

AI agents call disk_usage_report to retrieve information from Mcp Hands without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why disk_usage_report is rated Low

Even though disk_usage_report only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

RECOMMENDED RULE

The rule that runs disk_usage_report safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Hands, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For disk_usage_report, this is the rule to start with:

disk_usage_report Allowed

disk_usage_report is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "disk_usage_report": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Hands, apply this rule, and every disk_usage_report call is checked against it from then on.
