What it does

Written by AI from the README

Runs an MCP server inside Zotero so an agent such as Claude Code can manage your library. It can search, cite, edit items, organise collections, add by DOI or ISBN, and find duplicates. It also works with Better BibTeX and exports attachment files to a folder tree that follows your collections.

Lets an AI agent maintain your library directly, with a preview and confirmation step before bulk changes. Needs Zotero 10 and Better BibTeX, and covers My Library only.

Your rating of Zotero MCP v0.1.2

Your review is public, under the name you give, and published with the directory's data under CC BY 4.0. Links are removed. We never store your IP address: a scrambled code made from it is kept for 30 days to catch fake reviews. Every review is checked before it's published; how fake ones are spotted isn't published, so it can't be gamed.
