WHAT IT DOES

What get_kernel does on Linode MCP Server

AI agents call get_kernel 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 get_kernel is rated Low

This tool retrieves kernel information from Linode infrastructure. The verb 'Get' and the absence of any language suggesting modification, deletion, or execution means this is a read-only query operation. The blast radius of misuse is minimal since no resources are created, modified, or destroyed, and no code is executed.

From the tool's definition Tool name 'get_kernel' and description 'Get details for a specific kernel' indicate a retrieval operation with no modification or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

get_kernel Allowed

get_kernel 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": {
    "get_kernel": {}
  }
}

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 get_kernel call is checked against it from then on.
