smithery badge

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

Setup

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.

Set environment variables:

export ZOTERO_API_KEY="your-api-key"
export ZOTERO_USER_ID="user-id-from-curl"

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.

Install and run:

# Install globally (recommended)
npm install -g mcp-zotero
mcp-zotero

# Or run directly with npx
npx mcp-zotero
