Deep Research MCP Server

An advanced scholarly research MCP server that provides a uniform set of tools for discovering, fetching, processing, and managing scholarly content across multiple sources.

Overview

Deep Research is a Model Context Protocol (MCP) server that enables AI assistants like Claude to access and process scholarly literature from multiple sources, generate summaries, analyze citation networks, extract relationships between concepts, and more.

Scholarly Sources

The server integrates with multiple academic repositories:

• arXiv
• PubMed
• Semantic Scholar
• Google Scholar
• Google Drive (for document storage) (wip, annoying to setup)

Core Capabilities

• Cross-source paper search: Find papers across multiple repositories with a single query
• Full-text retrieval: Download and process complete academic papers
• AI-powered analysis: Generate structured summaries, highlight key information, and extract relationships
• Citation network analysis: Build and explore citation graphs
• Document management: Store research papers and notes to Google Drive

Installation & Setup

Installation

First, clone this repository and install the package:

# Clone the repository
git clone https://github.com/yourusername/mcp-deepresearch.git
cd mcp-deepresearch

# Install the package in development mode
pip install -e .

Configuration

The server requires configuration for API keys and credentials:

1. For Google Drive integration:

   • Create a deepresearch_credentials.json file with your Google API credentials
   • The first time you use Drive features, it will prompt for authentication

2. For API rate limits:

   • Some sources (especially Google Scholar) may require proxies for high-volume usage

Starting the Server

You can run the server in two ways:

1. Using the Python module:

python -m deepresearch

2. Using the start_server script:

python start_server.py

Connecting to Claude Desktop

To use the server with Claude Desktop:

1. Edit the Claude Desktop configuration file (located at ~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "deepresearch": {
      "command": "/path/to/python3",
      "args": [
        "-m",
        "deepresearch"
      ],
      "workingDir": "/path/to/mcp-deepresearch"
    }
  }
}

2. Replace /path/to/python3 with the path to your Python executable
3. Replace /path/to/mcp-deepresearch with the absolute path to your project
4. Restart Claude Desktop
5. Select “deepresearch” from the MCP server dropdown in Claude Desktop

5. Analyze citation network:

   @deepresearch get_citation_graph(paper_ids=["arxiv:2106.14843"], depth=2)
   

6. Compare papers:

   @deepresearch compare_papers(paper_ids=["arxiv:2106.14843", "arxiv:2103.12116"])
   

7. Save to Google Drive:

   @deepresearch store_to_drive(document=<pdf content>, paper_id="arxiv:2106.14843")
   

Debugging

You can debug the server using the Model Context Protocol Inspector:

npx @anthropic-ai/mcp-inspector@latest

Upon launching, the Inspector will display a URL that you can access in your browser to begin debugging.

Connector Testing

The project includes several test scripts for validating the functionality of connectors:

1. test_connectors.py: Basic validation for all connectors
2. test_connectors_download.py: Enhanced version for the full search-to-download pipeline
3. test_google_scholar_fix.py: Specialized test for the Google Scholar connector
4. test_semantic_scholar_direct.py: Direct test for Semantic Scholar API

Common Issues and Solutions

1. Google Scholar:

   • PDF download limitations are addressed by extracting ArXiv IDs for papers also hosted on ArXiv

2. Semantic Scholar:

   • Rate limiting issues are handled with API keys and retry logic

3. General Connectivity:

   • Use --connector parameter to test specific connectors
   • For detailed debugging, use specialized test scripts
