Get all calendar groups in the GoHighLevel location
AI agents call get_calendar_groups to retrieve information from GoHighLevel MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns calendar group information from a GoHighLevel location. It performs a read-only data retrieval operation with no ability to modify, delete, or execute actions. The blast radius of misuse is minimal—an AI agent could only access calendar group metadata already available to authenticated users.
