What patch_system_vm does on CloudStack MCP Server
AI agents invoke patch_system_vm to trigger actions in CloudStack MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why patch_system_vm is rated High
Patching a system VM involves executing patch operations on infrastructure-level virtual machines (like SSVM or CPVM in CloudStack), which can affect system availability and stability. It modifies the running state of critical system VMs. This is Execute-level since it triggers an external operational process, with high severity due to the potential impact on infrastructure-critical components.
From the tool's definition 'Patch system virtual machine' - applying patches to a running system VM triggers external operations that modify system state
Attacks that exploit this kind of access
The rule that runs patch_system_vm safely
PolicyLayer is an MCP gateway: it sits between your AI agents and CloudStack MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For patch_system_vm, this is the rule to start with:
patch_system_vm stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect CloudStack MCP Server, apply this rule, and every patch_system_vm call is checked against it from then on.
Questions about patch_system_vm
Patch system virtual machine. It is categorised as a Execute tool in the CloudStack MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the CloudStack MCP Server MCP server in PolicyLayer and add a rule for patch_system_vm: 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.
patch_system_vm is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the patch_system_vm 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 patch_system_vm. 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.
patch_system_vm 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.
