VulnFeed MCP server

<!-- mcp-name: io.github.novadyne-hq/vulnfeed -->

VulnFeed — Dependency Vulnerability Monitoring for Claude Code

An MCP server that scans your project dependencies for known vulnerabilities, enriches with EPSS exploit probability scores, and recommends fix versions.

Free tier — 10 scans/day, 1 monitored project, no signup required. Single-CVE lookup and webhooks need a license key or x402.

Install

uvx vulnfeed-mcp

MCP client config

Add to your MCP client config (~/.claude/settings.json for Claude Code, claudedesktopconfig.json for Claude Desktop):

Free tier (no signup, no API key):

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

Paid ($14/mo, unlimited scans + projects):

{
  "mcpServers": {
    "vulnfeed": {
      "command": "uvx",
      "args": ["vulnfeed-mcp"],
      "env": {
        "VULNFEED_API_KEY": "YOUR_LICENSE_KEY_HERE"
      }
    }
  }
}

x402 micropayments

VulnFeed also accepts x402 micropayments — AI agents can pay per scan with USDC on Base, no API key or signup needed. When the free tier limit is reached, the API returns HTTP 402 with payment requirements that x402-compatible clients handle automatically.

• $0.01 per scan
• $0.002 per CVE lookup
• $0.50 per project per 30 days of hourly webhook monitoring (renewable; the webhook receives an expiring event with the renew URL a day before)

Tools

Monitoring

Supported lockfiles

• package-lock.json (npm)
• yarn.lock (Yarn)
• pnpm-lock.yaml (pnpm)
• requirements.txt (pip)
• Pipfile.lock (Pipenv)
• go.sum / go.mod (Go)
• Cargo.lock (Rust)
• Gemfile.lock (Ruby)
• composer.lock (PHP)

How it works

1. Parses your lockfile to extract dependency names + versions
2. Queries OSV.dev (GitHub Advisories plus each ecosystem's security database) for known CVEs
3. Enriches with EPSS exploit probability scores
4. Filters noise — suppresses low-EPSS, non-critical CVEs by default
5. Sorts by exploitability — most likely to be exploited first
6. Returns fix versions from each advisory's affected-version ranges

Smart filtering

By default, VulnFeed suppresses low-priority CVEs (EPSS < 10% AND CVSS < 9.0). This cuts noise by ~80%.

Pass show_all=True to any scan tool to see everything.
