Mendeley MCP Server

An MCP (Model Context Protocol) server that connects your Mendeley reference library to LLM applications like Claude Desktop, Cursor, and other MCP-compatible clients.

Features

Search your library - Find papers by title, author, abstract, or notes

Search global catalog - Access Mendeley's 100M+ paper database
DOI lookup - Find papers by their DOI

Prerequisites

Mendeley Account - Sign up at mendeley.com (uses Elsevier authentication)
Mendeley API App - Register at dev.mendeley.com/myapps.html
- Sign in with your Elsevier credentials
- Click "Register a new app"
- Set redirect URL to http://localhost:8585/callback
- Select "Authorization code" flow (not Legacy)
- Note your Client ID and Client Secret

Installation

Using pip

pip install mendeley-mcp

Using uv (recommended)

uv tool install mendeley-mcp

Using Docker

docker run -it \
  -e MENDELEY_CLIENT_ID="your-client-id" \
  -e MENDELEY_CLIENT_SECRET="your-client-secret" \
  -e MENDELEY_REFRESH_TOKEN="your-refresh-token" \
  ghcr.io/pallaprolus/mendeley-mcp

Or build locally:

git clone https://github.com/pallaprolus/mendeley-mcp.git
cd mendeley-mcp
docker build -t mendeley-mcp .

From source

git clone https://github.com/pallaprolus/mendeley-mcp.git
cd mendeley-mcp
pip install -e .

Quick Start

1. Authenticate with Mendeley

Run the authentication wizard:

mendeley-auth login

This will:

Prompt for your Client ID and Client Secret
Open your browser to authorize the app
Save your credentials securely in your system keyring

2. Add to Claude Desktop

Edit your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Linux: ~/.config/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "mendeley": {
      "command": "mendeley-mcp"
    }
  }
}

If installed with uv:

{
  "mcpServers": {
    "mendeley": {
      "command": "uvx",
      "args": ["mendeley-mcp"]
    }
  }
}

3. Restart Claude Desktop

The Mendeley tools should now be available in Claude.

Available Tools

Tool	Description
`mendeley_search_library`	Search documents in your library
`mendeley_get_document`	Get full details of a specific document
`mendeley_list_documents`	List documents, optionally filtered by folder
`mendeley_list_folders`	List all folders/collections
`mendeley_search_catalog`	Search Mendeley's global paper database
`mendeley_get_by_doi`	Look up a paper by DOI
`mendeley_add_document`	Add a new document to your library

Example Usage

Once configured, you can ask Claude things like:

"Search my Mendeley library for papers about transformer architectures"
"What papers do I have in my 'Machine Learning' folder?"
"Find the paper with DOI 10.1038/nature14539 and summarize it"
"Search the Mendeley catalog for recent papers on protein folding"
"Add this paper to my library: [title, authors, etc.]"

Configuration

Environment Variables

If you prefer not to use mendeley-auth login, you can configure credentials via environment variables:

# Required
export MENDELEY_CLIENT_ID="your-client-id"
export MENDELEY_CLIENT_SECRET="your-client-secret"

# One of the following (refresh token recommended - access tokens expire quickly)
export MENDELEY_REFRESH_TOKEN="your-refresh-token"
# OR
export MENDELEY_ACCESS_TOKEN="your-access-token"

Or in your MCP config:

{
  "mcpServers": {
    "mendeley": {
      "command": "mendeley-mcp",
      "env": {
        "MENDELEY_CLIENT_ID": "your-client-id",
        "MENDELEY_CLIENT_SECRET": "your-client-secret",
        "MENDELEY_REFRESH_TOKEN": "your-refresh-token"
      }
    }
  }
}

Auth Commands

Important: This server runs locally on your machine. Your credentials and data never pass through any third-party servers - all communication is directly between your computer and Mendeley's API.

Credential Storage: Your OAuth tokens and client secret are stored securely in your system's native keyring (macOS Keychain, Windows Credential Locker, or Linux Secret Service). Only the non-sensitive client ID is stored in ~/.config/mendeley-mcp/credentials.json.

Rate Limits

Mendeley API rate limits are per-user. If you hit rate limits:

The server implements automatic token refresh
Wait a few minutes and retry
For heavy usage, consider spreading requests over time

Troubleshooting

"No credentials found"

Run mendeley-auth login to authenticate.

"Token expired"

Your access token has expired. The server will attempt to refresh it automatically using your refresh token. If this fails, run mendeley-auth login again.
