Maintenant

Maintenant: Self-hosted infrastructure monitoring tool with a built-in AI agent MCP server.

Maintenant is a self-hosted monitoring solution for Docker, Kubernetes, and bare Linux infrastructure. It automatically discovers containers, endpoints, TLS certificates, cron jobs, and CVEs without requiring PromQL, exporters, or complex dashboard creation. When issues occur, fixed rules trigger alerts, and the built-in Model Context Protocol server allows AI agents to investigate issues using logs and metrics. It supports integrations with Discord, webhooks, email, Telegram, Slack, and Teams. The system runs as a single Go binary with zero external dependencies.
