NVD MCP Server: Bridging AI Workflows with Vulnerability Data

Overview: What is NVD MCP Server?

The NVD MCP Server is a powerful tool that integrates seamlessly into AI development environments, providing real-time vulnerability data straight from the National Vulnerability Database (NVD). By leveraging the Model Context Protocol (MCP), this server acts as a bridge between conversational queries and intricate security databases. This integration ensures developers can address potential vulnerabilities effortlessly within their preferred IDEs, such as Claude Desktop.

🔧 Core Features & MCP Capabilities

The NVD MCP Server offers extensive features designed to enhance AI workflows. With the ability to perform CVE details lookup, keyword searches, recent vulnerability checks, and critical severity filtering, developers can maintain a high level of security without leaving their development environment.

Real-Time CVE Details Lookup

Developers can ask questions like "What's the scoop on CVE-2023-1234?" and receive detailed information about the vulnerability. This includes descriptions, CVSS scores, severities, and more, providing a comprehensive understanding of potential risks in their codebase.

Keyword Search for Vulnerabilities

Keyword searches allow users to discover vulnerabilities related to specific technologies or keywords. For instance, typing "Find CVEs related to Apache" will yield relevant results based on Apache-related security issues.

Recent CVEs Overview

The server also facilitates staying informed about the latest vulnerabilities by using commands like "Show me the latest CVEs from the past week," ensuring regular updates in the development process.

Critical Severity Filtering

Users can filter their queries with phrases such as "List critical vulnerabilities" to narrow down to the most urgent security risks, aiding in prioritizing mitigation efforts effectively.

⚙️ MCP Architecture & Protocol Implementation

The NVD MCP Server is built on top of the Model Context Protocol (MCP), a standardized protocol designed for AI applications. This server enhances AI workflows by providing real-time data through structured queries and responses.

🚀 Getting Started with Installation

Installation of the NVD MCP Server is straightforward and requires configuring both Python environment and API keys. Follow these steps to set up:

1. Clone the Repository:

   git clone https://github.com/sockcymbal/nvd-mcp-server.git
   

2. Set Up a Virtual Environment:

   cd nvd-mcp-server
   source venv/bin/activate  # On Windows: \(venv\Scripts\activate\) 
   

3. Install Dependencies:

   pip install -r requirements.txt
   

4. Configure Your NVD API Key:

   • Request a key from NVD API Key Request.
   • Create a keys.env file in the project root with:

     NVD_API_KEY=your_api_key_here
     

5. Launch the Server:

   python nvd_mcp.py --transport stdio
   

6. Connect Your Client/IDE/Agent:

   For Claude Desktop, add the following to your claude_desktop_config.json:

   {
     "mcpServers": {
       "nvd": {
         "command": "uv",
         "args": ["--directory", "/Path to nvd_mcp directory", "run", "nvd_mcp.py"]
       }
     }
   }
   

7. Query the Server:

   Use natural language commands such as:

   • "What's the deal with CVE-2023-1234?"
   • "Any recent critical vulnerabilities?"
   • "Search for CVEs mentioning Apache."
