List all option groups in CiviCRM
AI agents call list_option_groups to retrieve information from CiviCRM 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 simple read operation to enumerate option groups (CiviCRM's configuration metadata for dropdown lists and enumerations). It has no capability to modify, delete, or execute operations. The data retrieved is non-sensitive configuration information. Misuse by an AI agent would be limited to information disclosure with minimal blast radius.
From the tool's definition Tool name 'list_option_groups' and description 'List all option groups in CiviCRM' indicate a query operation that retrieves configuration data without modification or side effects.
