Check whether anything you depend on is known malware, before an agent installs it. `check_lockfile` 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. `scan_artifact` 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`

Register/verify your domains, queue security scans (headers, TLS, DNS, ports, CVEs + AI-specific checks) and read findings, for AI agents. Install with `npx -y eleion-scanner-mcp`.

Compliance and identity for AI agents — verify an agent's certificate scope, read its behavioral risk score, and append to an immutable audit trail. X.509 identity issued via AWS KMS; MiCA / EU AI Act aligned. `npx -y @kakunin/mcp`

Domain security reconnaissance for AI agents. 13 tools — DNS + DNSSEC, SSL/TLS chain & grade, HTTP security headers, SPF/DKIM/DMARC email auth, TCP port scan, ASN, RDAP/WHOIS — plus a one-shot `security_scan` returning a 0-100 Health Score (A–F). Free, no API key. `npx -y dechonet-mcp`

Agent identity, scoped delegation, and governance: issue passports, build and verify narrowing-only delegation chains, enforce policy at a gateway, and emit signed admission and outcome records. 150 tools. `npx -y agent-passport-system-mcp`
