List system capacity information
AI agents call list_capacity to retrieve information from CloudStack 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 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.
Attacks that exploit this kind of access
List system capacity information. It is categorised as a Read tool in the CloudStack MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CloudStack MCP Server MCP server in PolicyLayer and add a rule for list_capacity: 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 CloudStack MCP Server. Nothing to install.
list_capacity 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 list_capacity 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 list_capacity. 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.
list_capacity is provided by the CloudStack MCP Server MCP server (mozg31337/cloudstack-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
