Frequently asked questions

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.
