Get virtual machine user data
AI agents call get_vm_user_data 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 user data associated with a virtual machine. The verb 'get' and the absence of any language suggesting modification, deletion, execution, or financial impact place this firmly in the Read category. Reading VM user data has minimal blast radius since it only exposes configuration or metadata without altering infrastructure state.
From the tool's definition Tool name 'get_vm_user_data' and description 'Get virtual machine user data' indicate a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Get virtual machine user data. 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 get_vm_user_data: 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.
get_vm_user_data 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 get_vm_user_data 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 get_vm_user_data. 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.
get_vm_user_data 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.
