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.

Tools

Scanning

Tool	Description
scan_project	Auto-detect and scan all lockfiles in a directory
scan_lockfile	Scan a specific lockfile
check_package	Check a single package for vulnerabilities
lookup_cve	Detailed CVE info with EPSS + fix versions

Monitoring

Tool	Description
monitor_project	Register for continuous monitoring
check_alerts	New vulns since last scan
update_deps	Update snapshot after upgrading packages
list_monitored	See all monitored projects
unmonitor_project	Remove from 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 (NVD + GitHub Advisories) 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 version recommendations from package registries

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.

Continuous monitoring

1. monitor_project — takes a baseline snapshot of current deps + known vulns
2. check_alerts — diffs against baseline, surfaces only new vulns
3. Run check_alerts periodically to catch newly published CVEs
