RISK

Why calendar_create_event is rated Medium

This tool creates new calendar entries, which is a reversible write operation. It modifies calendar state by adding an event but does not execute arbitrary code, delete data, or move money. Severity is medium because misuse could create numerous unwanted calendar events causing schedule disruption and confusion, but the impact is contained to calendar data and can be undone by deletion.

From the tool's definition Tool description states "Create a new event in Google Calendar" with parameters for title, start time, end time, and optional attendees. The verb "create" and action of adding a calendar event represents data modification.

RECOMMENDED RULE

The rule that runs calendar_create_event safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Dialogbrain, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For calendar_create_event, this is the rule to start with:

calendar_create_event Rate-limited

calendar_create_event 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.

View as policy code

policy.json

{

          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Dialogbrain, apply this rule, and every calendar_create_event call is checked against it from then on.
