EndNote Library Connector

Search, cite, and read PDFs from your EndNote reference library directly in Claude Desktop

EndNote MCP

Tests PyPI Python License

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.

Tools Available to Claude

ToolDescription
search_referencesSearch by author, title, year, keywords, abstract (BM25 ranked, with DOI links)
search_fulltextSearch inside PDF content — find concepts, quotes, methods
search_libraryCombined metadata + PDF search in one call
search_semanticSearch by meaning using AI embeddings (requires endnote-mcp[semantic])
get_reference_detailsFull metadata for a reference (abstract, keywords, DOI, etc.)
get_citationFormat as APA 7th, Harvard, Vancouver, Chicago, or IEEE
get_bibtexExport references as BibTeX entries for LaTeX
get_bibliographyGenerate a formatted bibliography for multiple references
find_relatedFind similar references (uses embeddings when available)
read_pdf_sectionRead specific pages from a PDF attachment
list_references_by_topicBroad topic-based listing
rebuild_indexRe-index after updating your EndNote library

Adding New References

When you add new references to your EndNote library:

  1. Re-export XML from EndNote (overwrite the same file)
  2. Either:
    • Run endnote-mcp index from a terminal, or
    • Ask Claude: "Rebuild my library index"

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

OperationTime (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 7thget_citation(rec_number=42, style="apa7")
  • Harvardstyle="harvard"
  • Vancouverstyle="vancouver"
  • Chicago (Author-Date, 17th ed.) — style="chicago"
  • IEEEstyle="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_bibtex tool 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
