WHAT IT DOES

What list_capacity does on CloudStack MCP Server

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

RISK

Why list_capacity is rated Low

This tool retrieves system capacity data for informational purposes only. 'List' is a classic read operation with no side effects, and capacity information is non-sensitive infrastructure metadata. No data is created, modified, deleted, or executed. Blast radius if misused is minimal (information disclosure only).

From the tool's definition Tool name is 'list_capacity' and description states 'List system capacity information' — a clear read/query operation that retrieves capacity metrics without modification.

RECOMMENDED RULE

The rule that runs list_capacity safely

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

list_capacity Allowed

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

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

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

The button opens the PolicyLayer dashboard: create your workspace, connect CloudStack MCP Server, apply this rule, and every list_capacity call is checked against it from then on.
