publish_event · Eventbrite MCP Server MCP: Risk & Policy

WHAT IT DOES

What publish_event does on Eventbrite MCP Server

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

WHY IT NEEDS A POLICY

Why publish_event needs a policy

Publishing an event transitions it from draft state to live state, making it visible and available to the public. This is a state modification (Write category) rather than destructive, as the event can be unpublished or modified afterward.

From the tool's definition Tool description states 'Publish a draft event to make it live' — this modifies the state of an event from draft to published/live, which is a reversible state change that affects event visibility and availability.
