WHAT IT DOES

What list_groups does on Vultr MCP

AI agents call list_groups to retrieve information from Vultr MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_groups is rated Low

The tool appears to retrieve or enumerate groups within the Vultr infrastructure, consistent with a Read operation. No modification, execution, deletion, or financial action is suggested by the name. The low severity reflects the minimal risk of a simple listing operation—it exposes information but cannot modify or damage resources.

From the tool's definition Tool name 'list_groups' indicates a listing/retrieval operation with no apparent side effects. The naming convention matches the Read category pattern (list*, get*, fetch*).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_groups safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Vultr MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_groups, this is the rule to start with:

list_groups Allowed

list_groups is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_groups": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Vultr MCP, apply this rule, and every list_groups call is checked against it from then on.
