WHAT IT DOES

What performance_counters does on Mcp Windows

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

RISK

Why performance_counters is rated Low

The name 'performance_counters' strongly suggests reading system performance metrics (CPU, memory, disk, network usage), which is a read-only operation. However, with no description available, confidence is reduced. On a Windows automation server with 200+ tools, this likely queries performance counter data.

From the tool's definition Tool name: 'performance_counters'; description is empty and uninformative.

RECOMMENDED RULE

The rule that runs performance_counters safely

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

performance_counters Allowed

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

policy.json

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

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

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