This tool retrieves calendar data without creating, modifying, or deleting events. Retrieval operations are classified as Read category with low severity since they do not alter state or have side effects. The minimal risk is that an AI agent could read calendar data it shouldn't, but the operation itself is non-destructive and reversible.

From the tool's definition Tool name includes 'get_events' and description states 'Retrieve upcoming events from Google Calendar' — both indicate a query/retrieval operation with no modifications.

POLICY

How to control google_calendar_get_events

policy.json

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

google_calendar_get_events 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 MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
