What this skill does
MasterHttpRelayVPN Proxy Skill by ara.so — Daily 2026 Skills collection. MasterHttpRelayVPN is a domain-fronted HTTP/SOCKS5 proxy that tunnels traffic through Google Apps Script. It disguises requests as Google traffic to evade DPI/firewalls, performs local MITM TLS interception to re-encrypt traffic, and requires only a free Google account — no VPS needed. Traffic flow: --- Installation Behind a firewall (PyPI mirror): Quick start scripts (handles venv + deps automatically): --- Step 1: Deploy the Google Apps Script Relay 1.
