Why remove_user_from_group needs a policy

Removing a user from a group modifies their access permissions and group membership in Okta. While this action could potentially be reversed by re-adding the user, it can immediately revoke access to resources and applications tied to that group. This qualifies as a Write operation (reversible modification), but carries high severity due to the security and access control implications of unintended group removal.

POLICY

How to control remove_user_from_group

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

policy.json

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

remove_user_from_group 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.
