Why confirm_user_compromised needs a policy

This tool modifies the security state of a user account in Entra ID Identity Protection by marking them as compromised. This is a Write action (modifying user state/attributes) that could trigger automated responses like blocking sign-ins or requiring MFA reset. Misuse could lock out legitimate users or disrupt operations, warranting high severity.

From the tool's definition Mark an Entra ID user as compromised in Identity Protection. Sets the user

POLICY

How to control confirm_user_compromised

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

policy.json

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

confirm_user_compromised 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 Response 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.

Questions about confirm_user_compromised

What does the confirm_user_compromised tool do? +

How do I enforce a policy on confirm_user_compromised? +

Register the Response MCP Server MCP server in PolicyLayer and add a rule for confirm_user_compromised: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Response MCP Server. Nothing to install.

What risk level is confirm_user_compromised? +

confirm_user_compromised is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit confirm_user_compromised? +

Yes. Add a rate_limit block to the confirm_user_compromised rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block confirm_user_compromised completely? +

Set action: deny in the PolicyLayer policy for confirm_user_compromised. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides confirm_user_compromised? +

Enforce policy on every Response MCP Server tool call.

Start from Response MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
