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

Parses your lockfile to extract dependency names + versions
Queries OSV.dev (NVD + GitHub Advisories) for known CVEs
Enriches with EPSS exploit probability scores
Filters noise — suppresses low-EPSS, non-critical CVEs by default
Sorts by exploitability — most likely to be exploited first
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

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

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
$0.05 per project monitor setup
