EPSS MCP Project
The EPSS MCP Project is a powerful server designed to retrieve CVE details from the NVD API and fetch EPSS scores from the EPSS server. It provides users with comprehensive vulnerability information, including CVE descriptions, CWEs, CVSS scores, and EPSS percentiles, all in one place.
Features
- Comprehensive CVE Information: Fetch detailed vulnerability data, including descriptions, CWEs, and CVSS scores, directly from the NVD API.
- EPSS Integration: Retrieve EPSS scores and percentiles to assess the likelihood of exploitation for specific vulnerabilities.
- MCP Server: Serve data through a robust and extensible MCP server for seamless integration with other tools.
- Docker Support: Easily deploy the server using Docker for a consistent and portable runtime environment.
- VS Code Compatibility: Integrate with VS Code MCP for enhanced developer workflows and real-time vulnerability insights.
Prerequisites
- Python 3.13 or higher
- Docker (optional, for containerized deployment)
- An NVD API key (add it to the
.envfile asNVD_API_KEY)
Setup Instructions
1. Clone the Repository
git clone <repository-url>
cd epss-mcp-project
2. Install Dependencies
It is recommended to use a virtual environment. You can create one using venv or conda. Then, install the required packages:
pip install -r requirements.txt
3. Add Your NVD API Key
Create a .env file in the project root and add your NVD API key:
NVD_API_KEY=your-nvd-api-key
Usage
Installing via Smithery
To install EPSS Vulnerability Scoring Server for Claude Desktop automatically via Smithery:
npx -y @smithery/cli install @jgamblin/EPSS-MCP --client claude
Running the MCP Server Locally
To start the MCP server locally, run:
python epss_mcp.py
Once the server is running, you can make requests to retrieve CVE details by specifying the CVE ID.
Example Request
To get details for a specific CVE, use the following format:
GET /cve/<CVE-ID>
Replace <CVE-ID> with the actual CVE identifier (e.g., CVE-2022-1234).
Docker Deployment (for Open-WebUI)
If you want to run the MCP server in Open-WebUI, follow these steps:
1. Build the Docker Image
To build the Docker container, run:
docker build -t epss_mcp .
2. Run the Docker Container
Run the container and expose it on port 8000:
docker run -p 8000:8000 epss_mcp
The MCP server will now be accessible at http://localhost:8000.

Suggested System Prompt for WebUI
When using the MCP server in Open-WebUI, you can configure the following system prompt to guide interactions:
You are a specialized AI Assistant focused on the Exploit Prediction Scoring System (EPSS). Your expertise lies in delivering and interpreting EPSS data, which includes daily updated probability scores (0-1) and percentiles for Common Vulnerabilities and Exposures (CVEs), indicating the likelihood of their exploitation in the wild within the next 30 days. You are to help cybersecurity professionals understand these predictions, compare them with other metrics like CVSS scores, and use this information to prioritize vulnerability remediation efforts effectively. Provide actionable, data-driven insights in a clear, technically accurate, professional, and solution-oriented manner.
Serving to VS Code MCP
To serve the MCP server to VS Code MCP, follow these steps:
-
Add the Local Server to VS Code: Open your VS Code
settings.jsonfile and add the following configuration to register the local server:"mcp.servers": { "EPSS_MCP": { "type": "stdio", "command": "python", "args": [ "/Github/EPSS-MCP/epss_mcp.py" ] } }Note: Make sure to update the
argspath to match the location of theepss_mcp.pyfile on your local machine. -
Connect to VS Code:
- Open VS Code.
- Install the Microsoft Copilot Labs extension if not already installed.
- Ensure the MCP server is listed and active in the extension.
-
Start Using the MCP Server: Once connected, VS Code will call the Python file directly to fetch CVE details and EPSS scores.
