What is the MCP Zotero MCP server?

A Model Context Protocol server for Zotero integration that allows Claude to interact with your Zotero library. The mcp zotero mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 5 defined tools rather than through you.

Its toolset

Everything the assistant can do here goes through one of these:

  • get_collections — List all collections in your library
  • get_collection_items — Get items in a specific collection
  • get_item_details — Get detailed information about a paper
  • search_library — Search your entire library
  • get_recent — Get recently added papers

Adding it to your client

npx on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Configuration

You will need 4 environment variables: ZOTERO_API_KEY, ZOTERO_USER_ID, YOUR_API_KEY, YOUR_USER_ID. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

When to reach for it

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. MCP Zotero's toolset — get_collections, get_collection_items, get_item_details and 2 more — is a fair guide to whether it matches your workflow. It is maintained by kaliaboi; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the mcp zotero mcp server does with a few real requests.

Frequently asked questions

It connects MCP Zotero to MCP-compatible AI assistants such as Claude and Cursor, exposing 5 tools (get_collections, get_collection_items, get_item_details, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with MCP Zotero directly.
