There are great tools around Docker. But when I wanted an AI to help with my infrastructure, the same thing was missing everywhere: a management layer that is MCP-native and gives an AI the governance it needs. A fair assessment:

Positioning
Host & fleet management vs. AI-nativeness
Portainer
The go-to Docker UI. But real RBAC, audit logs and image-update notifications live in the Business Edition (free only up to 3 nodes); the Community Edition has just a simple user system. AI/MCP? Not there.

Coolify
Strong, but a PaaS (Heroku alternative): focused on deploying apps, not on fleet ops. Multi-node is rough and operations stay on you. In January 2026, 11 vulnerabilities were disclosed, three rated CVSS 10.0 (patched): exactly why an AI should never touch infrastructure without hard limits.

Komodo
A really good, free dashboard (multi-server, compose, audit). But entirely without native AI/MCP.

Docker's MCP Toolkit
Strong, but it solves a different layer: it runs MCP servers in containers and exposes them to agents. It does not manage your hosts, containers, CVEs and logs.

And Whiskers?
Honestly: a young 0.12-series beta (published releases on ghcr.io), solo project, open source: not "better than everyone". Rather, the MCP-native management layer with the governance an AI needs around your infrastructure: per-key permissions, code-enforced guardrails, approvals, full logging plus containers, logs, metrics, CVEs, deployment and databases in one tool.
