Get events from a Google Calendar with optional filtering
AI agents call getCalendarEvents to retrieve information from Google Drive MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves calendar event data without modifying, executing, or destroying anything. It is a straightforward read operation that queries existing calendar events with optional filters. The blast radius of misuse is minimal—an AI agent could potentially access calendar information it shouldn't, but cannot cause damage or irreversible changes.
From the tool's definition Tool name 'getCalendarEvents' and description 'Get events from a Google Calendar with optional filtering' indicate retrieval and querying operations only, with no modification, execution, or deletion of data.

PolicyLayer is an MCP gateway — it sits between your AI agents and Google Drive MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for getCalendarEvents:
{
"version": "1",
"default": "deny",
"tools": {
"getCalendarEvents": {}
}
}getCalendarEvents is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
