WHAT IT DOES

What list does on Vultr MCP

AI agents call list 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 is rated Low

Given the Vultr MCP context (cloud infrastructure management) and the 'list' naming convention alongside sibling tools focused on analysis and retrieval, this tool most likely retrieves or enumerates resources (instances, IPs, databases, etc.) without modifying state.

From the tool's definition Tool name 'list' with empty description suggests a data retrieval operation. Sibling tools include 'analyze_*' and 'add_*' operations across cloud infrastructure, indicating this server provides listing/querying capabilities. No evidence of side effects.

RECOMMENDED RULE

The rule that runs list 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, this is the rule to start with:

list Allowed

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

View as policy code

policy.json

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

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 call is checked against it from then on.
