List Virtual Machine Manager guests with their state and resource allocation.
AI agents call list_virtual_machines to retrieve information from Synology 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 displays data about virtual machines (state, resource allocation) with no side effects. It is a read-only operation that falls clearly into the Read category. Severity is low because listing VM information poses minimal risk—it merely exposes metadata about existing VMs without triggering actions, deleting data, or moving money.
From the tool's definition Tool name 'list_virtual_machines' and description 'List Virtual Machine Manager guests with their state and resource allocation' indicate a query/retrieval operation that returns information about VMs without modifying or executing anything.

List Virtual Machine Manager guests with their state and resource allocation. It is categorised as a Read tool in the Synology MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Synology MCP Server MCP server in PolicyLayer and add a rule for list_virtual_machines: 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 Synology MCP Server. Nothing to install.
list_virtual_machines 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_virtual_machines 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_virtual_machines. 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_virtual_machines is provided by the Synology MCP Server MCP server (rafalr100/synology-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
