Why get_instance_type needs a policy

This tool retrieves read-only information about Linode instance types (specifications and pricing). It has no side effects, does not execute code, does not modify infrastructure, and does not involve financial transactions. It is a straightforward data lookup operation.

From the tool's definition Tool name 'get_instance_type' and description 'Get details for a specific Linode type, including pricing and specifications' indicate a query operation that retrieves information without modifying or executing anything.

POLICY

How to control get_instance_type

PolicyLayer is an MCP gateway — it sits between your AI agents and Linode MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_instance_type:

policy.json

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

get_instance_type is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Linode MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
