List ISOs in the org library — name, source URL, SHA-256, uploader.
AI agents call list_isos to retrieve information from KVMFleet MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a simple enumeration of ISO images with their associated metadata. It retrieves information without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal—an attacker gains visibility into available ISOs but cannot alter infrastructure or trigger actions. This is a straightforward Read operation consistent with the server's read-only design.
From the tool's definition Tool name 'list_isos' and description 'List ISOs in the org library' indicate a query operation that retrieves metadata (name, source URL, SHA-256, uploader) without modification or side effects.
Attacks that exploit this kind of access
List ISOs in the org library — name, source URL, SHA-256, uploader. It is categorised as a Read tool in the KVMFleet MCP Server MCP Server, which means it retrieves data without modifying state.
Register the KVMFleet MCP Server MCP server in PolicyLayer and add a rule for list_isos: 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 KVMFleet MCP Server. Nothing to install.
list_isos 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_isos 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_isos. 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_isos is provided by the KVMFleet MCP Server MCP server (kvmfleet/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
