THE RISK

Medium Risk

Why disable_two_factor needs a policy

Disabling two-factor authentication is a reversible account configuration change (can be re-enabled), not permanent deletion, making it Write rather than Destructive. However, it significantly weakens account security and could enable unauthorized access if misused by an AI agent. The high severity reflects the security risk to the account, even though the action itself is not irreversible.

From the tool's definition Tool name is 'disable_two_factor' and description states it 'Disable two-factor authentication for your account'. This modifies account security settings by removing an authentication mechanism.

POLICY

How to control disable_two_factor

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 disable_two_factor:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "disable_two_factor": {
      "limits": [
        {
          "counter": "disable_two_factor_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

disable_two_factor stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. 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.
