Retrieve top-level items in a collection.
AI agents call collection_items_top to retrieve information from Mcp Zotero 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 collection items without modifying, deleting, or executing any operations. It is a straightforward Read operation with minimal security risk—even if called with unexpected arguments, it simply returns information rather than changing state.
From the tool's definition The tool description states it 'Retrieve[s] top-level items in a collection' — a read-only query operation with no side effects. The verb 'retrieve' and the context of querying library contents align with data retrieval.
