🔧 Advanced Configuration

Using Web API Instead of Local API

For accessing your Zotero library via the web API (useful for remote setups):

Environment Variables

• ZOTERO_LOCAL=true: Use the local Zotero API (default: false)
• ZOTERO_API_KEY: Your Zotero API key (for web API)
• ZOTERO_LIBRARY_ID: Your Zotero library ID (for web API)
• ZOTERO_LIBRARY_TYPE: The type of library (user or group, default: user)

Command-Line Options

📑 PDF Annotation Extraction

Zotero MCP includes advanced PDF annotation extraction capabilities:

• Direct PDF Processing: Extract annotations directly from PDF files, even if they're not yet indexed by Zotero
• Enhanced Search: Search through PDF annotations and comments
• Image Annotation Support: Extract image annotations from PDFs
• Seamless Integration: Works alongside Zotero's native annotation system

For optimal annotation extraction, it is highly recommended to install the Better BibTeX plugin for Zotero. The annotation-related functions have been primarily tested with this plugin and provide enhanced functionality when it's available.

The first time you use PDF annotation features, the necessary tools will be automatically downloaded.
