What is NVD Database MCP Server?

A Model Context Protocol server implementation that queries the NIST National Vulnerability Database (NVD) via its API, providing vulnerability data to MCP-compliant clients like Claude Desktop.

How to use NVD Database MCP Server?

Configure the server in the Claude Desktop config file by providing the path to uvx, the mcp-nvd argument, and your NVD API key as an environment variable. Then use the get_cve tool to retrieve a CVE by ID and the search_cve tool to search by keyword with optional parameters.

FAQ from NVD Database MCP Server

What prerequisites are needed to run this server?

Python 3.10 or higher, a free NVD API key (request at nvd.nist.gov), and the uv package manager.

How do I configure it for Claude Desktop?

Edit the Claude Desktop config file (claude_desktop_config.json) to add mcp-nvd under mcpServers with the command set to your uvx path, args ["mcp-nvd"], and the NVD_API_KEY environment variable.

Does it support Server-Sent Events (SSE) transport?

Yes, it supports SSE transport for real-time communication, and can be run with --transport sse --port 9090.

What tools does the server provide?

Two tools: get_cve (retrieve a CVE by ID) and search_cve (search by keyword with options for exact match, concise output, and result count up to 2000).

Where does the vulnerability data come from?

All data is fetched directly from the NIST National Vulnerability Database (NVD) via its public API.
