Feature & Specification Comparison

Specification	Vet safedep Security	Lazaretto MCP jamesdfinance-dev Security
Summary	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.	Check whether anything you depend on is known malware, before an agent installs it. checklockfile takes a package-lock.json, yarn.lock or pnpm-lock.yaml and matches every pinned version against published malicious-package advisories in one call, free and with no API key, catching compromised releases like chalk@5.6.1 while leaving their clean releases alone. scanartifact adds deterministic behavioral analysis (no LLM in the serving path) for credential theft, exfiltration, obfuscation, prompt injection and install-time droppers, with the file, line and evidence that triggered it; verdicts are SHA-256-bound so you can re-verify what landed on disk. Paid scans settle at $0.03 USDC on Base (x402) or prepaid credits. npx lazaretto-mcp
