WHAT IT DOES

What revoke_entra_sessions does on Response MCP Server

AI agents invoke revoke_entra_sessions to trigger actions in Response MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

THE RISK

High Risk

Why revoke_entra_sessions needs a policy

This tool triggers an external identity platform operation that invalidates active sessions and tokens across all devices and apps, forcing re-authentication. It is not purely destructive (sessions can be re-established via login), but it executes a significant external action with broad blast radius — misuse could lock out legitimate users across all their active sessions.

From the tool's definition Revoke all Entra ID (Azure AD) sign-in sessions and refresh tokens for a user. Forces re-authentication on all devices and applications.

POLICY

How to control revoke_entra_sessions

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 revoke_entra_sessions:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "revoke_entra_sessions": {
      "limits": [
        {
          "counter": "revoke_entra_sessions_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

revoke_entra_sessions stays usable, but rate-capped — a runaway agent can't fire it dozens of times 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.
