Tools & capabilities
Zotero MCP tools 3
zotero_item_metadataGet the complete metadata for a specific Zotero item, given the item key. Includes the citation key, publication details, identifiers, and timestamps.zotero_item_fulltextGet the full text content of a Zotero item, given the item key of a parent item or specific attachment.zotero_search_itemsSearch for items in your Zotero library. Returns a summary of each match; look up individual results with zotero_item_metadata or zotero_item_fulltext. Choosing a query mode: - 'titleCreatorYear' (the default) searches titles, creator names, and years. Use it for known-item lookup, where you know roughly what the item is called or who wrote it. - 'everything' additionally searches abstracts, the Extra field, note text, and the full text of attachments. Use it for topic and full-text search, where the term would not appear in a title. Words match by prefix, and space-separated words must all be present though not necessarily adjacent, so 'cybor insect' matches 'Cyborg Insect'. A hyphen separates words and switches the match to OR: 'oxygen-deprived' matches anything containing 'oxygen' or 'deprived', which is far broader than intended. Write hyphenated terms with a space to require both halves.
