What is Vulnfeed?

Vulnfeed is an MCP server that monitors your project’s dependencies for security vulnerabilities, native to Claude Code. It reads lockfiles, queries the NVD and GitHub Advisory Database for known CVEs, enriches results with EPSS (Exploit Prediction Scoring System) scores, and recommends exact fix versions from package registries. It is intended for developers using Claude Code who want continuous dependency vulnerability tracking.
