MCP Badge License: MIT Python 3.11+ MCP

Scopus MCP Server

Connects any MCP-compatible AI agent to the Elsevier Scopus academic database — search 100+ million scholarly records, retrieve full abstracts, analyze author impact, and track citation trends.

Works with: Claude Desktop · Claude Code · Cursor · VS Code Copilot · Windsurf · Zed · Continue.dev · any MCP client


Quickstart (2 minutes)

1. Get your Scopus API key (free) at dev.elsevier.com → Register → Create API Key

2. Install and run — pick one method:

# Option A: uvx (recommended — no environment setup needed)
uvx scopus-mcp

# Option B: pip
pip install scopus-mcp
scopus-mcp

3. Add to your AI client — see the Configuration section below.


Prerequisites

Python 3.11+

python --version   # needs 3.11 or higher
# Install if missing: https://python.org/downloads

uv (recommended)

# Windows
winget install astral-sh.uv

# macOS / Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

Installation

Option A — uvx (zero configuration)

# Install and run in a single command
uvx scopus-mcp

# Upgrade later
uv tool upgrade scopus-mcp

Option B — pip

pip install scopus-mcp

# Verify installation
scopus-mcp --help

Option C — From source (development)

git clone https://github.com/JOSETRA44/scopus-mcp.git
cd scopus-mcp
uv sync                    # installs all dependencies
cp .env.example .env       # edit .env with your API key
uv run scopus-mcp          # run directly from source

Terminal CLI

Besides running as an MCP server, scopus-mcp also installs three equivalent commands — scopus-mcp, scopus, and the short alias scps — as a standalone command-line tool for one-off lookups, testing your API key, or scripting, no MCP client required.

# Install globally as a uv tool (adds scopus / scps / scopus-mcp to PATH)
uv tool install --editable /path/to/scopus-mcp

scopus --help                 # list all subcommands
scopus check                  # validate your API key live against each endpoint
scopus search 'TITLE-ABS-KEY("machine learning")' --count 5
scps abstract 85180904906 --type scopus_id
scopus author 7401234567
scopus search-authors "AUTHLASTNAME(Smith)"
scopus search-affiliations "AFFIL(MIT)"
scopus citation-count --doi 10.1016/j.cell.2023.01.001
scopus citations 85180904906 --start-year 2020 --end-year 2024

Add --json to any subcommand for raw structured output (useful for piping into jq or scripts).

Running any of the three commands with no subcommand starts the MCP stdio server instead — the mode MCP clients (Claude Desktop, Claude Code, etc.) use. It will sit waiting for input on stdin; that's expected, not a hang.

Subcommand Equivalent MCP tool
search <query> scopus_search
abstract <id> --type ... scopus_get_abstract
author <author_id> scopus_get_author
search-authors <query> scopus_search_authors
search-affiliations <query> scopus_search_affiliations
citation-count --scopus-id/--doi scopus_get_citation_count
citations <scopus_id> scopus_get_citations_overview
check (CLI-only) diagnostic — live-checks your key against every endpoint

Configuration by Client

Replace YOUR_API_KEY_HERE with your actual Elsevier API key in every config block below.

Claude Desktop

Config file:

  • Windows: %APPDATA%\Claude\claude_desktop_config.json
  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "scopus": {
      "command": "uvx",
      "args": ["scopus-mcp"],
      "env": {
        "SCOPUS_API_KEY": "YOUR_API_KEY_HERE"
      }
    }
  }
}

Restart Claude Desktop after saving. A hammer icon (🔨) in the input bar confirms tools are loaded.

Claude Code (CLI)

Add to your project's .mcp.json (or .antigravity.json):

{
  "mcpServers": {
    "scopus": {
      "command": "uvx",
      "args": ["scopus-mcp"],
      "env": {
        "SCOPUS_API_KEY": "YOUR_API_KEY_HERE"
      }
    }
  }
}

From source (local development):

{
  "mcpServers": {
    "scopus": {
      "command": "uv",
      "args": [
        "--directory", "/absolute/path/to/scopus-mcp",
        "run", "scopus-mcp"
      ],
      "env": {
        "SCOPUS_API_KEY": "YOUR_API_KEY_HERE"
      }
    }
  }
}

Run /mcp in the Claude Code prompt to verify — you should see scopus with 7 tools.

Cursor

Global config: %APPDATA%\Cursor\User\globalStorage\cursor.mcp\mcp.json (Windows)

{
  "mcpServers": {
    "scopus": {
      "command": "uvx",
      "args": ["scopus-mcp"],
      "env": {
        "SCOPUS_API_KEY": "YOUR_API_KEY_HERE"
      }
    }
  }
}

VS Code + GitHub Copilot

Create .vscode/mcp.json in your workspace:

{
  "servers": {
    "scopus": {
      "type": "stdio",
      "command": "uvx",
      "args": ["scopus-mcp"],
      "env": {
        "SCOPUS_API_KEY": "YOUR_API_KEY_HERE"
      }
    }
  }
}

Windsurf

Config: %APPDATA%\Codeium\windsurf\mcp_config.json (Windows)

{
  "mcpServers": {
    "scopus": {
      "command": "uvx",
      "args": ["scopus-mcp"],
      "env": {
        "SCOPUS_API_KEY": "YOUR_API_KEY_HERE"
      }
    }
  }
}

Zed

Edit ~/.config/zed/settings.json:

{
  "context_servers": {
    "scopus": {
      "command": {
        "path": "uvx",
        "args": ["scopus-mcp"],
        "env": {
          "SCOPUS_API_KEY": "YOUR_API_KEY_HERE"
        }
      }
    }
  }
}

Continue.dev

Edit .continue/config.yaml:

mcpServers:
  - name: scopus
    command: uvx
    args:
      - scopus-mcp
    env:
      SCOPUS_API_KEY: "YOUR_API_KEY_HERE"

Generic stdio (any MCP client)

command:  uvx
args:     ["scopus-mcp"]
env:      SCOPUS_API_KEY=YOUR_API_KEY_HERE

TITLE-ABS-KEY("machine learning" AND cancer) AND PUBYEAR > 2020

# Reviews only
TITLE-ABS-KEY("federated learning") AND DOCTYPE(re)

# By author ID
AU-ID(7401234567) AND SUBJAREA(COMP)

Rate Limits

The server tracks rate limits from response headers and sleeps automatically before making calls when quota is exhausted.

Endpoint Weekly Quota
Scopus Search 20,000
Abstract Retrieval 5,000
Author Retrieval 5,000
Citation Count 50,000
Citations Overview 5,000

Tip: Use scopus_get_citation_count (50K quota) for bulk citation checks. Reserve scopus_get_abstract (5K quota) for the papers you actually need in detail.


Verify It's Working

# Fastest check: validates your API key live against every endpoint
scopus check

# Interactive browser UI (recommended for MCP-specific debugging)
npx @modelcontextprotocol/inspector uvx scopus-mcp

# Quick smoke test (server starts and exits cleanly)
echo "" | SCOPUS_API_KEY=your_key uvx scopus-mcp

# Unit tests (from source)
uv sync --group dev
uv run pytest tests/ -v
# Expected: 19 passed

Troubleshooting

command not found: uvx Install uv: https://docs.astral.sh/uv/getting-started/installation/

Configuration error: Missing required environment variable: SCOPUS_API_KEY Make sure your config's "env" block has "SCOPUS_API_KEY": "your_actual_key" — not a placeholder.

Tools fail with HTTP 401 API key is invalid or expired. Regenerate at dev.elsevier.com.

Tools fail with HTTP 403 Your key may lack Scopus access. An institutional subscription is required for most endpoints. Ask your librarian about SCOPUS_INST_TOKEN.

First run is slow uv downloads and caches the package on first run. Subsequent starts take ~0.2s.

Tools appear but return empty results Try broadening your query: replace TITLE(...) with TITLE-ABS-KEY(...) or remove PUBYEAR constraints.
