Vulners MCP

Vulners MCP is a Model Context Protocol (MCP) server that provides seamless access to the Vulners vulnerability database through AI assistants like Claude Desktop. It enables security researchers and developers to query comprehensive vulnerability data, search for CVEs, analyze security bulletins, and audit software packages directly through natural language conversations. Its 7 documented tools cluster into read & search, audit, bulletin.

People connecting API integration tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Vulners MCP

before you install - you'll need

Set VULNERS_API_KEY, MCP_TRANSPORT_MODE, VULNERS_BASE_URL before connecting.

Claude Code

claude mcp add vulnerscom-vulners-mcp -- uvx vulners-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "vulnerscom-vulners-mcp": {
      "command": "uvx",
      "args": [
        "vulners-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license no standard license detected - usage rights unclear; check the repo before commercial use

pypi package vulners-mcp - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.vulnersCom is GitHub-verified and matches the repo owner
