Stream Guard

StreamGuard

StreamGuard is a survival-server guardrail for communities that want world interaction gated behind live stream verification.

Unverified players can be allowed to move, chat, and use safe commands, or they can be frozen, command-limited, or kicked. World-affecting actions are configured separately, so each server can choose how strict the live requirement should be.

Server Target

• Paper/Spigot 1.20.1+
• Java 17+
• Classic plugin.yml
• No NMS or CraftBukkit internals

Player Flow

Players manage their stream link from the server:

/stream setup
/stream status
/stream link twitch <channel-login>
/stream link youtube <channel-id-or-@handle>
/stream verify
/stream cancel

Admins manage access, manual verification, and bypasses:

/streamguard status <player>
/streamguard bypass grant <player> [duration] [reason]
/streamguard bypass remove <player>
/streamguard verify <player> [manual|twitch|youtube] [reason]
/streamguard unverify <player> [reason]
/streamguard reload

Bypass durations support s, m, h, and d suffixes, such as 30m, 2h, or 1d. Omitting the duration grants a persistent bypass.

Configuration

config.yml separates player state rules from world-affecting action rules.

• enforcement.unlinked controls players who have not linked a stream account.
• enforcement.not-live controls linked players who are not currently live.
• enforcement.blocked-actions controls block break/place, containers, pickup/drop, crafting, trading, entity damage/interact, buckets, fire, and other guarded interactions.
• onboarding.enabled controls the optional provider-picker setup flow.
• onboarding.provider-picker controls the chest GUI title, rows, filler item, cancel item, and provider buttons.
• onboarding.chat-input controls chat input timeout, max length, cancel keyword, and whether to verify immediately after linking.
• web.live-feed controls the optional live feed API, CORS origins, refresh interval, and provider metadata cache for the companion site.
• commands.safe-while-unverified keeps commands such as /stream, /login, and /register usable when command blocking is enabled.

Each state can independently allow or block movement, chat, commands, and kick-on-join.

Providers

Twitch verification uses the Helix streams API with:

providers:
  twitch:
    enabled: true
    client-id: ""
    client-secret: ""

YouTube verification uses the YouTube Data API with:

providers:
  youtube:
    enabled: true
    api-key: ""

YouTube links accept either a channel ID or @handle.

Provider identity is modeled as data, not as a closed enum. A future provider, such as Discord streaming presence, can add an infrastructure adapter and register its provider ID without changing the core access policy.

Companion Site

The optional live wall lives at minecraft-stream-guard-site. It reads StreamGuard's /api/live feed and renders the currently live players as a fullscreen web wall.

Support

StreamGuard is free and open source. If it helps your server, you can support development on Ko-fi.
