List the saved hashtag groups in the workspace. Each group has a name and a list of hashtags the user can append to posts. Use this to discover hashtag group ids before referencing them in schedule_post.
AI agents call list_hashtag_groups to retrieve information from Viraly MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists existing hashtag group data without modifying, deleting, or executing any actions. It is purely informational, used to enumerate workspace resources. No data is created, modified, or destroyed, and no external operations are triggered. This is a straightforward Read operation with minimal security risk.
