Which MCP Server Should You Choose?
Choose Vet when:
You need dedicated capabilities in the Security domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: API Key required (Free / Open Source).
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.
Pre-install guardian for npm packages with static code analysis, supply-chain attack detection, vulnerability audit (npm + GitHub Advisory Database), AI hallucination guard, and CycloneDX 1.6 SBOM generation with VEX. 28 MCP tools. Zero runtime dependencies — the SBOM serializer is implemented natively against the public CycloneDX schema.
