Minecraft Account Manager

A Discord-first account registry for a private Java Edition Minecraft network. Players link Discord to one or more Minecraft accounts, while a fail-closed Velocity plugin admits only registered accounts.

Workspace layout

• apps/web — Next.js 16 web application and API, styled with Tailwind CSS v4
• apps/discord-bot — discord.js slash-command bot
• packages/contracts — shared Zod contracts and CloudEvents types
• packages/database — PostgreSQL Drizzle schema and versioned migrations
• plugins/velocity — fail-closed Velocity admission plugin

Requirements

• Node.js 22+
• npm 11+
• Docker with Compose, or PostgreSQL 17+

Local setup

cp .env.example .env.local
docker compose up -d postgres
npm install
npm run db:migrate
npm run dev

Set DISCORD_GUILD_ID and DISCORD_INVITE_URL in .env.local so unauthenticated visitors can reach the Discord server. The HTTPS invite is the most reliable way to open Discord or join; the landing page also offers a discord:// app link.

Set IP_INTELLIGENCE_PROVIDER=proxycheck, add PROXYCHECK_API_KEY, and configure trusted proxy handling before allowing users to add accounts. Portal and game logins continue if lookup fails, but user account additions fail closed when an address is unknown, VPN, proxy, or Tor.

Open http://localhost:3000.

Validation

npm test
npm run typecheck
npm run lint
npm run build
npm run velocity:build

Database workflow

Always create and apply versioned migrations:

npm run db:generate
npm run db:migrate

Do not use drizzle push; it bypasses the reviewed migration history and can cause destructive schema changes.

Provision or rotate a Velocity API token after migrating:

npm run plugin:create-credential --workspace @minecraft-account-manager/database -- velocity-main

The token is displayed once and stored only as a SHA-256 hash.

Confirmed product decisions

• PostgreSQL and Drizzle ORM
• Keycloak OIDC for admin access with the minecraft-account-manager-admin role
• Admin user search, account management, primary-account changes, and Discord nickname synchronization
• Deployment-managed Discord guild ID and invite URL
• discord.js bot with /register and /account
• Java Edition online-mode accounts only
• Velocity admission checks are fail closed
• ProxyCheck.io geolocation and VPN/proxy/Tor detection with a 48-hour PostgreSQL cache
