What the publisher says

From the Zotero Library repository's README, as published. We do not edit it. Read it on GitHub

zotero-library-mcp

An MCP server that lets Claude, Codex, and ChatGPT add papers and books to your Zotero library by DOI, arXiv ID, or ISBN — and manage your collections, tags, and items.

The server supports both MCP transports used by these clients:

  • stdio (default) for Claude Code, Claude Desktop, Codex CLI/IDE, and the ChatGPT desktop app
  • Streamable HTTP for a hosted ChatGPT app or any remote MCP client

Tools

Adding papers

  • addpaperbydoi** — Resolve a DOI via CrossRef and add the paper to Zotero (with duplicate detection)
  • addpapersbydois** — Batch-add up to 50 papers at once
  • addpaperbyarxivid — Add a preprint by arXiv ID (uses DOI when available, falls back to arXiv metadata)
  • additemfrommetadata** — Create any supported Zotero item type from validated manual metadata

Adding books

  • addbookbyisbn** — Resolve an ISBN via Open Library and add the book to Zotero (with duplicate detection)

Searching & browsing

  • list_libraries — Discover the API key owner's personal library and shared group libraries, with IDs and key permissions
  • searchlibrary** — Search your Zotero library by title, author, tag, etc., paginated via start/limit (falls back to fuzzy matching when the exact search returns no results)
  • getitemdetails — View full metadata for any item
  • getrecentitems — List recently added items
  • getunfileditems — Get items not in any collection
  • searchfulltext** — Search Zotero metadata and indexed full text
  • findduplicates** — Find duplicate items by DOI, ISBN, or normalized title
  • listattachments** — List every attachment and choose a specific PDF key
  • healthcheck** — Verify library credentials, access, and storage configuration

Reading & annotating

  • getitemfulltext — Return bounded plain text from Zotero's index or a PDF, without leaking temporary paths
  • getbibtex** — Read-only BibTeX/BibLaTeX export for items, a collection, or the full library
  • savebibtex** — Save an export to an authorized local path
  • getannotations** — List all highlights and annotations on a paper's PDF
  • createannotation** — Highlight a text passage in a PDF (searches for the exact text, creates a visible highlight in Zotero's reader, and returns a preview image for verification). Smart overlap handling: exact duplicates update the existing comment; sub-passages get a contrasting highlight color automatically.
  • addnote** — Add a note to an item
  • listnotes, updatenote, deletenote** — Manage existing notes
  • updateannotation, deleteannotation — Edit or remove annotations

File attachments

  • attachfile** — Attach a local file over stdio or a ChatGPT file input over HTTP
  • downloadpdf** — Return a remote-safe MCP file resource
  • savepdf** — Save a PDF to an authorized local path

Collections

  • listcollections** — List all collections (with nesting)
  • createcollection** — Create a new collection (optionally nested under a parent)
  • getcollectionitems — Browse items in a collection, paginated via start/limit
  • addtocollection — Add an existing item to a collection
  • removefromcollection — Remove an item from a collection (keeps it in your library)
  • renamecollection, movecollection — Reorganize collections

Tags

  • listtags** — List all tags in your library
  • addtags** — Add one or more tags to an item (with optional color)
  • removetags** — Remove tags from an item
  • deletetags** — Delete tags from the entire library
  • settagcolor — Assign a color to a tag (appears in Zotero's tag selector)
  • renametag** — Rename a tag across all items in your library
  • unsettagcolor — Remove a tag color without deleting the tag
