Get recent announcements for a team (broadcast emails, broadcast alerts, and in-app messages unified into one feed, sorted by most recent).
AI agents call teamsnap_get_announcements to retrieve information from TeamSnap MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a data query operation that retrieves announcements without creating, modifying, deleting, or executing any actions. It has no side effects and presents minimal risk if misused by an AI agent—the worst outcome would be accessing announcements that an authenticated user already has permission to view.
From the tool's definition Tool name 'get_announcements' and description 'Get recent announcements' indicates a retrieval operation with no modifications.
