Is an API Key mandatory?

No. The NVD API allows public access without a key. However, using a key increases your rate limit significantly (up to 50 requests per 30 seconds).

What is a CPE string?

CPE (Common Platform Enumeration) is a structured naming scheme for information technology systems, software, and packages (e.g., cpe:2.3:a:microsoft:exchange_server:2019).

How far back can I search for vulnerabilities?

The NVD contains vulnerabilities dating back to the late 1990s. You can search the entire database by ID or keyword.

Troubleshooting NIST NVD MCP Server with Claude Desktop

Common issues when connecting NIST NVD to Claude Desktop through the Vinkius, and how to resolve them.

Server not appearing after restart

Ensure the JSON is valid (no trailing commas). Check the file path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\\Claude\\ (Windows).

Authentication error

Verify your Vinkius token is correct. Go to cloud.vinkius.com to regenerate it if needed.

Tools not showing in chat

Click the 🔌 icon at the bottom of the chat input. If it shows 0 tools, the server may still be connecting — wait a few seconds.

NIST NVD + Claude Desktop FAQ

Common questions about integrating NIST NVD MCP Server with Claude Desktop.

How does Claude Desktop discover MCP tools?

When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.

What happens if the MCP server is temporarily unavailable?

Claude Desktop handles disconnections gracefully — if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.

Can I connect multiple MCP servers simultaneously?

Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.

Is there a limit on the number of tools per server?

Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.

Does Claude Desktop support Streamable HTTP transport?

Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL — Claude auto-negotiates the transport protocol.
