Get all tags used in your Zotero library.
AI agents call zotero_get_tags to retrieve information from Zotero MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries and returns tag metadata from the Zotero library without creating, modifying, or deleting any data. It has no side effects and poses minimal risk if called by an AI agent, making it a low-severity Read operation.
