WHAT IT DOES

What create_event does on AirMCP

AI agents use create_event to create or update resources in AirMCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AirMCP environment.

RISK

Why create_event is rated Medium

This tool creates calendar entries, which is a reversible write operation. The severity is medium rather than high because: (1) calendar events can be deleted or modified to undo mistakes, (2) the tool has intentional limitations (no recurring events, no programmatic attendee addition) that reduce potential for harmful automation, and (3) the blast radius of accidental misuse is limited to calendar clutter rather…

From the tool's definition Tool name is 'create_event' and description states 'Create a new calendar event.' This is an explicit create operation that adds new data to the user's calendar system.

RECOMMENDED RULE

The rule that runs create_event safely

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

create_event Rate-limited

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.

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