sandbox: Fast cold-boot MicroVM sandboxes for AI agents on cocoon

by cocoonstack · MCP Server · ★ 86

Last updated: · Indexed by AgentSkillsHub · Auto-synced every 8h

Security audit verdict: SAFE · quality 63/100

None of the 42 rules matched — no credential harvesting, no data exfiltration, no curl-pipe-shell installer. Scanned against 42 published rules built on the SlowMist agent-security taxonomy, refreshed every 8 hours.

The quality score combines nine heuristic checks of the repo and its README: completeness, clarity, specificity, examples, structure, agent readiness, step-by-step content, instruction quality and security notes. It rates how well the project explains itself to an agent, not the code.

About sandbox

sandbox MicroVM sandboxes for AI agents, built on cocoon: a fast-boot guest stack, an in-guest product daemon, a per-node control plane with warm pools, and SDKs for Go and Python. Warm claims are sub-millisecond; a pool miss clones from a golden snapshot in tens of milliseconds; cold boot is 0.2–0.4 s on bare metal. Cloud Hypervisor serves both network lanes.

How this security grade is produced

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy: 42 published rules, covering credential harvesting, data exfiltration, curl | sh installers and more. It is a first-layer scan, not a manual audit — we say so rather than overstate it.

The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
