ProtectCord - Advanced IP Protection for Minecraft

Protect your Minecraft server from VPNs, proxies, bots, and malicious connections with real-time IP intelligence.

ProtectCord uses advanced IP reputation data to automatically block suspicious connections before they can harm your server. Perfect for preventing alt accounts, bot attacks, and maintaining a trustworthy player base.

✨ Key Features

IP Protection

  • 🛡️ Real-Time IP Verification - Every connection is checked against our threat intelligence database
  • 🚫 Block VPNs & Proxies - Stop ban evaders and alt accounts in their tracks
  • ⚠️ Risk-Based Blocking - Configurable threat levels from LOW to CRITICAL
  • 🌐 Geo-Blocking - Block or whitelist specific countries/regions
  • ✅ Smart Whitelist System - Bypass protection for trusted players, IPs, or UUIDs

Moderation System

  • ⚡ 3-Strike Warning System - Automatic escalation from warning to ban
  • 🔨 Player Warnings - Track and manage player behavior violations
  • 🚨 Auto-Ban System - Automatically ban players after 3 warnings
  • 📋 Warning History - View complete warning logs for any player
  • 🔒 Ban Management - Manual ban/unban commands with persistent storage

Platform & Performance

  • 🌐 Multi-Platform Support - Works on Paper, Spigot, Folia, BungeeCord, Velocity, and Forge
  • 📢 Discord Integration - Get real-time alerts when suspicious players are blocked
  • ⚡ Lightweight & Fast - Async IP checks won't slow down your server
  • 📊 Built-in Statistics - Monitor your API usage and blocked connections

🎮 Supported Platforms

Platform Versions Best For
Paper 1.13 - 1.21+ Modern optimized servers (recommended)
Spigot 1.8.8 - 1.21+ Legacy servers and vanilla Spigot
Folia 1.19+ High-performance multithreaded servers
Velocity 3.0+ Modern proxy networks (recommended)
BungeeCord 1.8.8 - 1.21+ Proxy networks (Waterfall compatible)
Forge 1.20.1+ Modded servers (server-side only)

📥 Quick Setup

1️⃣ Get Your Free API Key

  1. Visit protectcord.com
  2. Create a free account
  3. Generate an API key from the dashboard
  4. Free API key includes 32 requests per minute!

2️⃣ Install the Plugin

  1. Download the correct version for your platform from Modrinth
  2. Drop the JAR into your plugins/ folder

⚙️ Configuration

Simple, powerful configuration with sensible defaults:

# Your ProtectCord API key
api-key: "YOUR_API_KEY_HERE"

# What to block
enable-ip-check: true
block-vpn: true           # Block VPN connections
block-proxy: true         # Block proxy servers
block-datacenter: false   # Block datacenter IPs (hosting providers)
block-bogon: true         # Block invalid/bogus IPs

# Risk threshold - how strict should blocking be?
# Options: LOW, MEDIUM, HIGH, CRITICAL
blocked-risk-level: "HIGH"

# Discord webhooks (optional)
discord-webhook:
  enabled: false
  url: ""
  events:
    denied: true      # Alert when players are blocked
    accepted: false   # Alert when players connect
    whitelisted: true # Alert when whitelisted players join
    error: true       # Alert on API errors

Note: Velocity users use config.toml format instead of YAML

⚡ 3-Strike Warning System

Automatically manage player behavior with our progressive discipline system:

How It Works

1st Warning → Player receives an in-game chat warning

  • Notified of their violation
  • Warning count displayed (1/3)
  • Given a chance to correct behavior

2nd Warning → Player is kicked from the server

  • Receives final warning message
  • Told they have ONE more chance
  • Warning count: 2/3

3rd Warning → Automatic permanent ban

  • Player is permanently banned
  • All warning reasons listed in ban message
  • Ban persists across server restarts

Example Usage

/protectcord warn Notch Spamming in chat
→ Notch warned (1/3)

/protectcord warn Notch Using excessive caps
→ Notch kicked (2/3 warnings)

/protectcord warn Notch Harassment
→ Notch permanently banned (3/3 warnings)

Warning Management

  • View History: /protectcord warnings <player> - See all warnings with timestamps
  • Manual Ban: /protectcord ban <player> <reason> - Ban without warnings
  • Unban: /protectcord unban <player> - Remove ban (warnings remain)
  • Persistent Storage: All warnings saved to warnings.yml or warnings.toml

🛡️ How It Works

Detection System

ProtectCord checks every connecting player against our threat intelligence database:

  • ✅ VPN Detection - Identifies virtual private networks used to hide real IPs
  • ✅ Proxy Detection - Detects HTTP/SOCKS proxies and anonymizers
  • ✅ Datacenter IPs - Flags hosting providers (common for bots)
  • ✅ Risk Scoring - AI-powered risk assessment from UNKNOWN to CRITICAL
  • ✅ Bogon Detection - Blocks invalid/reserved IP ranges

Risk Levels Explained

Level What It Means Default Action
UNKNOWN Not enough data ✅ Allow
LOW Clean IP address ✅ Allow
MEDIUM Some suspicious activity ✅ Allow (configurable)
HIGH Known malicious activity ❌ Block
CRITICAL Active threat/attacker ❌ Block

Tip: Customize blocking threshold with blocked-risk-level in your config!

Automatic Bypasses

Smart detection automatically allows:

  • Localhost - 127.0.0.1, ::1
  • Private networks - 192.168.x.x, 10.x.x.x, 172.16-31.x.x
  • Whitelisted players - Configured via commands or config file

📢 Discord Webhook Integration

Get notified instantly when suspicious players try to connect!

Setup in 30 Seconds

1. Create Discord Webhook

  • Server Settings → Integrations → Webhooks → New Webhook
  • Copy the webhook URL

2. Add to config:

discord-webhook:
  enabled: true
  url: "https://discord.com/api/webhooks/YOUR_WEBHOOK_HERE"
  events:
    denied: true  # Get alerts when players are blocked

3. Reload: /protectcord reload

What You'll See

  • 🔴 Connection Denied - Player blocked (includes IP, reason, risk level)
  • 🟢 Connection Accepted - Player allowed (optional)
  • 🔵 Whitelisted Join - Trusted player connected
  • 🟠 API Error - Problem with IP check

❓ FAQ

Is this free to use? Yes! Our free API key includes 32 requests per minute which is plenty for most servers.

Will this lag my server? No! IP checks are 100% asynchronous and won't block the main thread. Most checks complete in under 100ms.

Can I whitelist my staff/friends? Absolutely! Use /protectcord whitelist add player <name> or whitelist by UUID/IP for permanent bypass.

What if a legitimate player gets blocked? Whitelist them with /protectcord whitelist add player <name>. You can also adjust blocked-risk-level to be less strict.

Does this work with offline mode? Yes, but we recommend online mode for better security. The plugin works on both.

Can I use this on a proxy network? Yes! Install only on the proxy (BungeeCord/Velocity) for network-wide protection. Don't install on backend servers.

What happens if the API is down? By default, players are allowed to connect if the API is unreachable. This prevents lockouts during maintenance.

Where is my data stored? Only IP addresses are sent to the ProtectCord API for checking. No player data, UUIDs, or usernames are transmitted. See our privacy policy.
