Why mark_notifications_read needs a policy

This tool modifies notification state (read status) for the authenticated user, which is a reversible write operation. It does not execute arbitrary code, delete data permanently, or move money. While it changes state in the system, the scope is limited to the user's own notification preferences and the change is easily reversible (notifications can be marked unread again).

From the tool's definition Tool name 'mark_notifications_read' and description 'Mark all notifications as read for the authenticated user' indicate a state change operation that modifies notification records.

How to control mark_notifications_read

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "mark_notifications_read": {
      "limits": [
        {
          "counter": "mark_notifications_read_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

mark_notifications_read 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.
