●●SolidSolve My ProblemShip It

Egress filtering for npm malware and rogue AI agents when most firewalls only handle ingress.

Strengths

•Fails closed by default blocking all traffic if rules are missing or invalid.
•Real-time mitmweb interface shows all proxied traffic for monitoring.
•Systemd integration with automatic iptables rule cleanup on service stop.

Weaknesses

•Ubuntu-only with no support for other Linux distributions or macOS.
•MITM approach breaks certificate pinning and may interfere with legitimate apps.

Agent Panopticon – Proxy sidecar for autonomous AI agents

Forcing an agent's traffic through a transparent mitmproxy while using iptables as a killswitch and swapping placeholder tokens for real secrets is a neat, practical approach to hardening autonomous agents. The idea shows real domain knowledge, but the repo is an MVP — many features are TODO, docs and use cases are thin, and mitmweb feels like a temporary dev choice rather than a finished UX.
