List Virtual Private Clouds
AI agents call list_vpcs 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.
The 'list' operation retrieves existing VPC data without creating, modifying, or deleting any resources. This is a passive read operation that only queries the state of Virtual Private Clouds. No side effects or irreversible actions are performed.
From the tool's definition Tool name 'list_vpcs' and description 'List Virtual Private Clouds' indicate a retrieval/query operation with no modification of infrastructure.

Register the CloudStack MCP Server MCP server in PolicyLayer and add a rule for list_vpcs: 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_vpcs 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_vpcs 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_vpcs. 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.
