Medium Risk

Why security-disable-user needs a policy

Disabling a user account is a state change that can be reversed (re-enabled), making it a Write action rather than Destructive. However, it has high severity because unauthorized disabling of user accounts could block legitimate access, disrupt operations, and impact multiple users depending on the account's role and permissions in the Sitecore system.

From the tool's definition The tool description states it 'Disables the Sitecore user account,' which is a reversible modification of user state/configuration rather than permanent deletion. The action modifies account status but does not destroy data or permanently remove the user.

POLICY

How to control security-disable-user

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Sitecore, and nothing reaches the server without passing your rules. This is the rule we recommend for security-disable-user:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "security-disable-user": {
      "limits": [
        {
          "counter": "security-disable-user_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

security-disable-user 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 Mcp Sitecore — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
