WHAT IT DOES

What list_instance_types does on Linode MCP Server

AI agents call list_instance_types to retrieve information from Linode MCP Server 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_instance_types is rated Low

This tool retrieves or enumerates available Linode instance type configurations (likely CPU, RAM, pricing, etc.). Listing instance types has no side effects—it does not create, modify, delete, or execute anything. It is a safe informational query suitable for AI agents to call without risk.

From the tool's definition Tool name 'list_instance_types' uses the verb 'list', indicating a retrieval operation. The sibling tools on this Linode server include 'list_instances' and 'list_regions', establishing a pattern where 'list_*' tools are read-only queries.

RECOMMENDED RULE

The rule that runs list_instance_types safely

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

list_instance_types Allowed

list_instance_types 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_instance_types": {}
  }
}

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

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