WHAT IT DOES

What list_calendars does on AirMCP

AI agents call list_calendars to retrieve information from AirMCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_calendars is rated Low

This tool retrieves metadata about calendars (names, colors, writable status) without creating, modifying, deleting, or executing any operations. It is a straightforward query/list operation with no capability to alter system state. The severity is low because calendar enumeration presents minimal risk even if misused by an AI agent.

From the tool's definition Tool description states it 'List all calendars with name, color, and writable status' — a purely informational retrieval operation with no modification or side effects.

list_calendars Allowed

list_calendars is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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