opengenes-mcp

MCP (Model Context Protocol) server for OpenGenes database

This server implements the Model Context Protocol (MCP) for OpenGenes, providing a standardized interface for accessing aging and longevity research data. MCP enables AI assistants and agents to query comprehensive biomedical datasets through structured interfaces.

The server automatically downloads the latest OpenGenes database and documentation from Hugging Face Hub (specifically from the opengenes folder), ensuring you always have access to the most up-to-date data without manual file management.

The OpenGenes database contains:

• lifespan_change: Experimental data about genetic interventions and their effects on lifespan across model organisms
• gene_criteria: Criteria classifications for aging-related genes (12 different categories)
• gene_hallmarks: Hallmarks of aging associated with specific genes
• longevity_associations: Genetic variants associated with longevity from population studies

If you want to understand more about what the Model Context Protocol is and how to use it more efficiently, you can take the DeepLearning AI Course or search for MCP videos on YouTube.

Usage Example

Here's how the OpenGenes MCP server works in practice with AI assistants:

Example showing how to query the OpenGenes database through an AI assistant using natural language, which gets translated to SQL queries via the MCP server. You can use this database both in chat interfaces for research questions and in AI-based development tools (like Cursor, Windsurf, VS Code with Copilot) to significantly improve your bioinformatics productivity by having direct access to aging and longevity research data while coding.

About MCP (Model Context Protocol)

MCP is a protocol that bridges the gap between AI systems and specialized domain knowledge. It enables:

• Structured Access: Direct connection to authoritative aging and longevity research data
• Natural Language Queries: Simplified interaction with specialized databases through SQL
• Type Safety: Strong typing and validation through FastMCP
• AI Integration: Seamless integration with AI assistants and agents

Data Source and Updates

The OpenGenes MCP server automatically downloads data from the longevity-genie/bio-mcp-data repository on Hugging Face Hub. This ensures:

• Always Up-to-Date: Automatic access to the latest OpenGenes database without manual updates
• Reliable Distribution: Centralized data hosting with version control and change tracking
• Efficient Caching: Downloaded files are cached locally to minimize network requests
• Fallback Support: Local fallback files are supported for development and offline use

The data files are stored in the opengenes subfolder of the Hugging Face repository and include:

• open_genes.sqlite - The complete OpenGenes database
• prompt.txt - Database schema documentation and usage guidelines

Available Tools

This server provides three main tools for interacting with the OpenGenes database:

1. opengenes_db_query(sql: str) - Execute read-only SQL queries against the OpenGenes database
2. opengenes_get_schema_info() - Get detailed schema information including tables, columns, and enumerations
3. opengenes_example_queries() - Get a list of example SQL queries with descriptions

Available Resources

1. resource://db-prompt - Complete database schema documentation and usage guidelines
2. resource://schema-summary - Formatted summary of tables and their purposes

Quick Start

Installing uv

# Download and install uv
curl -LsSf https://astral.sh/uv/install.sh | sh

# Verify installation
uv --version
uvx --version

uvx is a very nice tool that can run a python package installing it if needed.

Running with uvx

You can run the opengenes-mcp server directly using uvx without cloning the repository:

# Run the server in streamed http mode (default)
uvx opengenes-mcp

# Or explicitly specify stdio mode
uvx opengenes-mcp stdio

# Run the server in streamable HTTP mode on default (3001) port
uvx opengenes-mcp server

# Run on a specific port
uvx opengenes-mcp server --port 8000

# Run the server in SSE mode
uvx opengenes-mcp sse

In cases when there are problems with uvx often they can be caused by clenaing uv cache:

uv cache clean

The HTTP mode will start a web server that you can access at http://localhost:3001/mcp (with documentation at http://localhost:3001/docs). The STDIO mode is designed for MCP clients that communicate via standard input/output, while SSE mode uses Server-Sent Events for real-time communication.

Note: Currently, we do not have a Swagger/OpenAPI interface, so accessing the server directly in your browser will not show much useful information. To explore the available tools and capabilities, you should either use the MCP Inspector (see below) or connect through an MCP client to see the available tools.

Configuring your AI Client (Anthropic Claude Desktop, Cursor, Windsurf, etc.)

Quick Configuration Example

Here's what you can copy directly into your Claude Desktop or Cursor MCP configuration:

{
  "mcpServers": {
    "opengenes-mcp": {
      "command": "uvx",
      "args": ["opengenes-mcp"],
      "env": {
        "MCP_TRANSPORT": "stdio"
      }
    }
  }
}

Alternative: Using Preconfigured Files

We also provide preconfigured JSON files for different use cases:

• For STDIO mode (recommended): Use mcp-config-stdio.json
• For HTTP mode: Use mcp-config.json
• For local development: Use mcp-config-stdio-debug.json

Configuration Video Tutorial

For a visual guide on how to configure MCP servers with AI clients, check out our configuration tutorial video for our sister MCP server (biothings-mcp). The configuration principles are exactly the same for the OpenGenes MCP server - just use the appropriate JSON configuration files provided above.

Inspecting OpenGenes MCP server

npx @modelcontextprotocol/inspector --config mcp-config-stdio.json --server opengenes-mcp

npx @modelcontextprotocol/inspector --config mcp-config.json --server opengenes-mcp

npx @modelcontextprotocol/inspector --config mcp-config-stdio-debug.json --server opengenes-mcp

npx @modelcontextprotocol/inspector

Integration with AI Systems

Simply point your AI client (like Cursor, Windsurf, ClaudeDesktop, VS Code with Copilot, or others) to use the appropriate configuration file from the repository.

Repository setup

# Clone the repository
git clone https://github.com/longevity-genie/opengenes-mcp.git
cd opengenes-mcp
uv sync

Running the MCP Server

If you already cloned the repo you can run the server with uv:

# Start the MCP server locally (HTTP mode)
uv run server

# Or start in STDIO mode  
uv run stdio

# Or start in SSE mode
uv run sse

Database Schema

Example Queries

-- Get top genes with most lifespan experiments
SELECT HGNC, COUNT(*) as experiment_count 
FROM lifespan_change 
WHERE HGNC IS NOT NULL 
GROUP BY HGNC 
ORDER BY experiment_count DESC 
LIMIT 10;

-- Find genes that increase lifespan in mice
SELECT DISTINCT HGNC, effect_on_lifespan 
FROM lifespan_change 
WHERE model_organism = 'mouse' 
AND effect_on_lifespan = 'increases lifespan' 
AND HGNC IS NOT NULL;

-- Get hallmarks of aging for genes
SELECT HGNC, "hallmarks of aging" 
FROM gene_hallmarks 
WHERE "hallmarks of aging" LIKE '%mitochondrial%';

-- Find longevity associations by ethnicity
SELECT HGNC, "polymorphism type", "nucleotide substitution", ethnicity 
FROM longevity_associations 
WHERE ethnicity LIKE '%Italian%';

-- Find genes with both lifespan effects and longevity associations
SELECT DISTINCT lc.HGNC 
FROM lifespan_change lc 
INNER JOIN longevity_associations la ON lc.HGNC = la.HGNC 
WHERE lc.HGNC IS NOT NULL;

Safety Features

• Read-only access: Only SELECT queries are allowed
• Input validation: Blocks INSERT, UPDATE, DELETE, DROP, CREATE, ALTER, TRUNCATE operations
• Error handling: Comprehensive error handling with informative messages

Testing & Verification

The MCP server is provided with comprehensive tests including LLM-as-a-judge tests that evaluate the quality of responses to complex queries. However, LLM-based tests are disabled by default in CI to save costs.

Environment Setup for LLM Agent Tests

If you want to run LLM agent tests that use MCP functions with Gemini models, you need to set up a .env file with your Gemini API key:

# Create a .env file in the project root
echo "GEMINI_API_KEY=your-gemini-api-key-here" > .env

Note: The .env file and Gemini API key are only required for running LLM agent tests. All other tests and basic MCP server functionality work without any API keys.

Running Tests

Run tests for the MCP server:

uv run pytest -vvv -s

You can also run manual tests:

uv run python test/manual_test_questions.py

You can use MCP inspector with locally built MCP server same way as with uvx.

Note: Using the MCP Inspector is optional. Most MCP clients (like Cursor, Windsurf, etc.) will automatically display the available tools from this server once configured. However, the Inspector can be useful for detailed testing and exploration.

If you choose to use the Inspector via npx, ensure you have Node.js and npm installed. Using nvm (Node Version Manager) is recommended for managing Node.js versions.

Database Coverage

Currently, this MCP server uses only a subset of the complete OpenGenes database. The full OpenGenes database contains additional tables and data that are not yet included in our MCP implementation. We need contributors to help extend support for the complete database! If you're interested in helping expand the database coverage, please see our Contributing section.

Test Coverage

While we provide comprehensive tests including LLM-as-a-judge evaluations, not all test cases have been manually verified against the actual OpenGenes web interface. Some automated test results may need manual validation to ensure accuracy. Contributions to improve test coverage and validation are welcome.
