listVirtualMachines(4.21) 호출. 주요 필터만 노출(추가 필드는 mold_call 사용).
AI agents call mold_listVirtualMachines to retrieve information from ABLESTACK MOLD 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 and queries virtual machine inventory from CloudStack infrastructure without side effects. It is a read-only operation that exposes filtered listing of existing resources. While the underlying ABLESTACK MOLD system manages cloud infrastructure, this specific tool merely enumerates VMs and poses minimal risk compared to tools that could execute, delete, or modify systems.
From the tool's definition Tool name 'listVirtualMachines' and description explicitly states it is a list/query operation ('listVirtualMachines(4.21) 호출') that retrieves virtual machine data with filtering capabilities.

listVirtualMachines(4.21) 호출. 주요 필터만 노출(추가 필드는 mold_call 사용). It is categorised as a Read tool in the ABLESTACK MOLD MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ABLESTACK MOLD MCP Server MCP server in PolicyLayer and add a rule for mold_listVirtualMachines: 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 ABLESTACK MOLD MCP Server. Nothing to install.
mold_listVirtualMachines 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 mold_listVirtualMachines 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 mold_listVirtualMachines. 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.
mold_listVirtualMachines is provided by the ABLESTACK MOLD MCP Server MCP server (ycyun/ablestack-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
