Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

[](https://smithery.ai/server/mcp-zotero)

A Model Context Protocol server for Zotero integration that allows Claude to interact with your Zotero library.

Setup

  1. Get your Zotero credentials:
# First, create an API key at https://www.zotero.org/settings/keys
# Then use it to get your user ID:
curl -H "Zotero-API-Key: YOUR_API_KEY" https://api.zotero.org/keys/current

The response will look like:

{
"userID": 123456,
"username": "your_username",
"access": {
"user": {
"library": true,
"files": true,
"notes": true,
"write": true
}
}
}

The userID value is what you need.

  1. Set environment variables:
export ZOTERO_API_KEY="your-api-key"
export ZOTERO_USER_ID="user-id-from-curl"
  1. Verify your credentials:
# Test that your credentials work:
curl -H "Zotero-API-Key: $ZOTERO_API_KEY" \
"https://api.zotero.org/users/$ZOTERO_USER_ID/collections"

You should see your collections list in the response.

  1. Install and run:
# Install globally (recommended)
npm install -g mcp-zotero
mcp-zotero

# Or run directly with npx
npx mcp-zotero

Questions

What is the Zotero Connector MCP server?

A connector for Claude Desktop to work with collection and sources on your Zotero Cloud.

What tools does Zotero Connector expose?

5 in total: 5 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Zotero Connector safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Zotero Connector need?

It reads ZOTERO_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does Zotero Connector run?

It speaks stdio, so it runs as a local process your client starts. It is published on npm as mcp-zotero at 1.0.6.

How current is this page?

The grade is for one exact copy of the source (092ca892e19a), read on 2026-10-06. The repository is watched and re-audited when it changes.
