Why auth_status needs a policy

This tool performs a simple status check—a read-only operation that returns information about whether the user is authenticated. It has no side effects, does not create, modify, or delete data, does not execute code or commands, and does not involve financial transactions. The blast radius of misuse is minimal, as authentication status queries cannot harm the user's data or trigger unintended actions.

From the tool's definition Tool name 'auth_status' and description 'Check authentication status with Google Photos' indicate a query operation that retrieves authentication state without modifying, executing external actions, or affecting data.

POLICY

How to control auth_status

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "auth_status": {}
  }
}

auth_status is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Google Photos 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.
