Guardian (OSV Security Scanner)

GuardianMCP is a security-focused MCP server built by Kalvisan that provides proactive vulnerability scanning for project dependencies through integration with the OSV (Open Source Vulnerabilities) database. The implementation offers automated vulnerability detection with configurable severity filtering, supports multiple package managers, and includes Docker deployment with multi-stage builds for optimized container size. Built with TypeScript and the MCP SDK, it features npm audit integration, outdated package checking, and structured vulnerability reporting with remediation guidance. Designed for security-conscious development workflows, it enables automated dependency scanning during package installations, before commits, or on explicit security requests, making it valuable for maintaining secure codebases and implementing proactive security monitoring in CI/CD pipelines.
