190 MCP servers and agent skills in the Security category, ranked by quality score.
vet-mcp checks open source packages—like those suggested by AI coding tools—for vulnerabilities and malicious code. It supports npm and PyPI, and runs locally via Docker or as a standalone binary for fast, automated vetting.
Server security auditing and hardening toolkit. 413 security checks across 29 categories (SSH, Firewall, Docker, TLS, HTTP Headers), CIS/PCI-DSS/HIPAA compliance mapping, 19-step production hardening, fleet management, and forensic evidence collection. Supports Hetzner, DigitalOcean, Vultr, and Linode. 13 MCP tools.
Open-source runtime security proxy for MCP. Transparently intercepts every tools/call through an 18-class attack defense pipeline (prompt injection, SSRF, shell injection, SQL injection, credential exfil, polyglot attacks) with a YAML policy engine and 304-entry adversarial corpus. Trust scoring for npm MCP packages with 0-100 badges. Cloud dashboard, Docker image, Python SDK. MIT.
PCI DSS v4.0.1 static-analysis MCP server for Go payment codebases. 12 scanners detect PAN/CVV exposure, weak crypto, missing audit logs, vulnerable deps, TLS misconfig, auth weaknesses, plus CycloneDX 1.6 SBOM generation - each finding mapped to the exact PCI requirement. AI-assisted triage via triage_findings. Keyless-signed multi-arch Docker image on ghcr.io.
