Get ISO by name or filename.
AI agents call get_iso_by_name to retrieve information from Vultr MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about an ISO image based on its name or filename. It is a query/fetch operation that returns data without side effects, state changes, or triggering external operations. Even in a cloud infrastructure context, retrieving metadata about available ISO images poses minimal risk—it does not execute, modify, delete, or allocate resources. Classified as Read with low severity.
From the tool's definition Tool name 'get_iso_by_name' and description 'Get ISO by name or filename' indicate a retrieval operation with no modification or execution of code.

PolicyLayer is an MCP gateway — it sits between your AI agents and Vultr MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_iso_by_name:
{
"version": "1",
"default": "deny",
"tools": {
"get_iso_by_name": {}
}
}get_iso_by_name is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get ISO by name or filename. It is categorised as a Read tool in the Vultr MCP MCP Server, which means it retrieves data without modifying state.
Register the Vultr MCP server in PolicyLayer and add a rule for get_iso_by_name: 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 Vultr MCP. Nothing to install.
get_iso_by_name 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_iso_by_name 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_iso_by_name. 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_iso_by_name is provided by the Vultr MCP server (rsp2k/mcp-vultr). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Vultr MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
