ismailperim··on Why MCP Was Always a Bad Idea
This issue isn't just about communication methods and technical details. It's also about “standards”, and it will become increasingly important over time. As we begin to integrate AI into everything-for example, into banks...

ismailperim··on Show HN: OnCallMate – AI agent for autonomous Docker incident RCA
Great questions - you're right on both fronts.

*Node metrics:* Currently we're container-only (docker stats/logs), so yes - we'd miss noisy neighbors or node-level memory pressure. Prometheus integration is on the roadmap to correlate container events with node/cluster metrics. Right now we catch the obvious cases: "this container OOMKilled at its 512MB limit."

*Permissions:* Funny story - I built this while working with OpenClaw (an AI assistant framework). OpenClaw has broad system access by design, but I wanted to explore: what if we made a micro-agent with the minimum permissions needed?

So OnCallMate offers two modes: 1. *Direct socket* (if you trust it / testing): bind /var/run/docker.sock 2. *docker-socket-proxy* (production): read-only layer, no exec/restart/POST

The proxy approach: - Agent connects via TCP, never touches the socket directly - Whitelist: containers, logs, stats, inspect (GET only) - Blacklist: exec, restart, swarm, secrets - Even if AI hallucinates "docker restart nginx", it physically can't

All tool calls are logged for audit trails.

You're right that we should emphasize this more in the README. Principle: treat AI agents like untrusted input.

Have you seen other patterns for safely exposing Docker APIs to automation?
