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:

   hljs language-bash

   Copy

   # 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:

   hljs language-json

   Copy

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

   The userID value is what you need.

2. Set environment variables:

   hljs language-bash

   Copy

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

3. Verify your credentials:

   hljs language-bash

   Copy

   # 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.

4. Install and run:

   hljs language-bash

   Copy

   # Install globally (recommended)
   npm install -g mcp-zotero
   mcp-zotero
   
   # Or run directly with npx
   npx mcp-zotero
