EndNote Library Connector
Search, cite, and read PDFs from your EndNote reference library directly in Claude Desktop
EndNote MCP
Connect your EndNote reference library to Claude AI. Search references, read PDFs, format citations, find related papers, and generate bibliographies — all directly in Claude Desktop conversations.
What It Does
Once set up, you can ask Claude things like:
- "Search my library for social capital and Bourdieu"
- "Find papers about how organisations deal with uncertainty" (semantic search)
- "Find references related to paper #3844"
- "Give me the APA citation for reference #1234"
- "Generate a bibliography for references 12, 45, 78, 102"
- "Export references 12, 45, 78 as BibTeX"
- "Read pages 5-7 from that Smith et al. paper"
Claude searches your local library — nothing is uploaded to the cloud beyond the normal conversation.
How It Works
EndNote Library → XML Export → endnote-mcp index → SQLite Database (FTS5 + Embeddings)
↕
Claude Desktop ← MCP Server (12 tools)
Your references and PDF text are indexed into a local SQLite database with full-text search. Optionally, AI embeddings enable semantic search — finding papers by meaning, not just keywords. When semantic dependencies are installed, new references are automatically embedded during indexing. Claude connects through the Model Context Protocol (MCP).
Requirements
- EndNote 20+ (any edition)
- Claude Desktop app
- Python 3.10+
- uv (recommended) or pip
Quick Start
1. Install
# With uv (recommended)
uv tool install endnote-mcp
# Or with pip
pip install endnote-mcp
2. Export your library from EndNote
In EndNote: File → Export → choose XML format → save to a convenient location (e.g., Desktop).
3. Run the setup wizard
endnote-mcp setup
The wizard will:
- Auto-detect your XML export and PDF directory
- Create the configuration
- Index your library
- Configure Claude Desktop automatically
4. Restart Claude Desktop
Quit and reopen Claude Desktop. You'll see "EndNote Library" in your MCP connectors.
That's it. Start asking Claude about your references.
Semantic Search (Optional)
Enable meaning-based search that finds references even when they use different terminology than your query. For example, searching "how companies prepare for uncertain futures" finds papers on scenario planning and strategic foresight.
# Install semantic search dependencies
pip install endnote-mcp[semantic]
# Generate embeddings (~3 min for 4,000 references)
endnote-mcp embed
This uses the lightweight all-MiniLM-L6-v2 model locally — no API keys needed, everything stays on your machine.
Commands
| Command | What It Does |
|---|---|
endnote-mcp setup | Interactive setup wizard |
endnote-mcp index | Re-index after adding new references (incremental) |
endnote-mcp index --full | Full re-index from scratch |
endnote-mcp index --skip-pdfs | Index metadata only (fast, ~1 sec) |
endnote-mcp index --embed | Re-index and generate embeddings |
endnote-mcp embed | Generate semantic search embeddings |
endnote-mcp embed --full | Regenerate all embeddings from scratch |
endnote-mcp status | Show index statistics |
endnote-mcp install | Add to Claude Desktop config |
endnote-mcp serve | Start MCP server (used by Claude Desktop automatically) |
Tools Available to Claude
| Tool | Description |
|---|---|
search_references | Search by author, title, year, keywords, abstract (BM25 ranked, with DOI links) |
search_fulltext | Search inside PDF content — find concepts, quotes, methods |
search_library | Combined metadata + PDF search in one call |
search_semantic | Search by meaning using AI embeddings (requires endnote-mcp[semantic]) |
get_reference_details | Full metadata for a reference (abstract, keywords, DOI, etc.) |
get_citation | Format as APA 7th, Harvard, Vancouver, Chicago, or IEEE |
get_bibtex | Export references as BibTeX entries for LaTeX |
get_bibliography | Generate a formatted bibliography for multiple references |
find_related | Find similar references (uses embeddings when available) |
read_pdf_section | Read specific pages from a PDF attachment |
list_references_by_topic | Broad topic-based listing |
rebuild_index | Re-index after updating your EndNote library |
Adding New References
When you add new references to your EndNote library:
- Re-export XML from EndNote (overwrite the same file)
- Either:
- Run
endnote-mcp indexfrom a terminal, or - Ask Claude: "Rebuild my library index"
- Run
Indexing is incremental — it only processes new references and PDFs, not the entire library again. If semantic search is installed, new references are automatically embedded.
Performance
| Operation | Time (4,000 references) |
|---|---|
| Metadata indexing | ~1 second |
| PDF extraction (first time) | ~1 min per 100 PDFs |
| PDF extraction (incremental) | Only new PDFs |
| Embedding generation | ~3 minutes |
| Keyword search | < 50 ms |
| Semantic search | < 200 ms |
Configuration
Config is stored at:
- macOS:
~/Library/Application Support/endnote-mcp/config.yaml - Windows:
%APPDATA%/endnote-mcp/config.yaml - Linux:
~/.config/endnote-mcp/config.yaml
endnote_xml: /path/to/your/library.xml
pdf_dir: /path/to/your/Library.Data/PDF
db_path: /path/to/library.db # auto-set by setup
max_pdf_pages: 30 # max pages per read request
Citation Styles
Five built-in styles:
- APA 7th —
get_citation(rec_number=42, style="apa7") - Harvard —
style="harvard" - Vancouver —
style="vancouver" - Chicago (Author-Date, 17th ed.) —
style="chicago" - IEEE —
style="ieee"
Use get_bibliography to format multiple references at once, sorted by author or year.
BibTeX Export
Export references as BibTeX entries for use in LaTeX:
- Ask Claude: "Export references 42 and 100 as BibTeX"
- Or use the
get_bibtextool directly with comma-separated record numbers
Generates complete entries with proper entry types (@article, @book, @inproceedings, etc.), cite keys, and all available fields.
Troubleshooting
"No configuration found" — Run endnote-mcp setup
"XML file not found" — Re-export from EndNote: File → Export → XML format
"PDF not found" — Check that pdf_dir in your config points to the correct .Data/PDF directory
Search returns no results — Run endnote-mcp index to rebuild the database
Claude Desktop doesn't show the tool — Run endnote-mcp install, then restart Claude Desktop
"Semantic search is not available" — Run pip install endnote-mcp[semantic] then endnote-mcp embed
