Three deploy-ready Apps Script files live here. They all speak the same {k, m, u, h, b, ct, r} wire protocol with mhrv-rs, so the client just points its script_id at whichever deployment you want — no mode change required.

Variants and origins

Code.gs — standard relay. Verbatim mirror of upstream. Apps Script does the outbound fetch itself. This is the default choice for most users.
- Upstream: https://github.com/masterking32/MasterHttpRelayVPN/blob/python_testing/apps_script/Code.gs
- Credit: @masterking32. We do not modify this file.
- The mirror lives here so that (a) users on networks where raw.githubusercontent.com is unreachable can still deploy from a git clone / ZIP, and (b) we have a snapshot to diff against if upstream changes silently break the informal relay protocol.
CodeFull.gs — superset of Code.gs that additionally proxies raw-TCP / UDP via tunnel-node (used by mode: "full"). Maintained in this repo — written for this Rust port and not present upstream. Deploy this if you want full-tunnel mode; details in the file's header comment.
Code.cfw.gs — Apps Script becomes a thin auth+forward layer; the actual outbound fetch happens on a Cloudflare Worker you also deploy (assets/cloudflare/). Derivative work — not unmodified upstream. The pattern of forwarding through a Cloudflare Worker came from denuitt1/mhr-cfw; this file inherits hardening from Code.gs (decoy-on-bad-auth, fail-closed sentinels) and adds chunked batch forwarding (Promise.all on the Worker side, ceil(N/40) GAS calls per batch) that the upstream mhr-cfw does not have. Faster per-call latency, worse YouTube long-form, no fix for Cloudflare anti-bot. Read assets/cloudflare/README.md before choosing this one.

What you must edit before deploying

For every variant: change AUTH_KEY from its placeholder to a strong secret, and use that same string in your mhrv-rs config's auth_key. Code.cfw.gs additionally requires setting WORKER_URL to your deployed Cloudflare Worker URL; CodeFull.gs additionally requires TUNNEL_SERVER_URL and TUNNEL_AUTH_KEY for the tunnel-node leg.
