This blocks an IP after 3 failed logins within 5 seconds.
Small server owners (often hosting on home connections or cheap VPS) search for free solutions because:
If you run Spigot, Paper, or Purpur (the most common server software), plugins are your best friend. The following are completely free and specifically designed for anti-bot protection.
The phrase "minecraft bot attack free" is often searched by desperate server owners who think they must pay for protection. That is simply not true. Mojang's built-in settings, open-source plugins, and standard Linux firewall tools provide enterprise-grade protection at exactly zero cost.
Remember: Bot attackers use free tools, so you can use free defenses. The asymmetry works in your favor because defense is stateless (one firewall rule blocks thousands of bots), while attack requires scaling resources.
Your next steps:
Your server can be safe, stable, and completely free from bot attacks. minecraft bot attack free

Stopping the Storm: How to Protect Your Minecraft Server from Bot Attacks for Free
Nothing kills the vibe of a growing Minecraft server faster than a bot attack. Whether it’s hundreds of "players" flooding your lobby to crash the TPS or automated spam filling your chat, these attacks are a headache for any owner.
The good news? You don’t need a massive budget to stay online. Here is how you can build a professional-grade defense using free tools. 1. The Power of "FlameCord" (Velocity/BungeeCord)
If you run a network, the first step is hardening your proxy. FlameCord is a free fork of BungeeCord and Velocity specifically designed to fix Netty exploits and mitigate low-level bot attacks. It’s a "drop-in" replacement that filters out bad packets before they ever touch your game servers. 2. Install a Dedicated Anti-Bot Plugin connection_throttle: 5000 connection_throttle_limit: 3
For most server owners, a specialized plugin is the easiest line of defense.
UltimateAutoLib / AntiBot: Look for plugins that offer "Geyser" support if you allow Bedrock players.
nAntiBot: A popular free choice that uses "hidden" challenges (like asking a player to move or click a specific item) to verify they aren't a script. 3. Implement a "Limbo" or "Queue" System
Bots usually fail when they have to do something "human." By using a Limbo plugin, you can send new connections to a tiny, empty world where they must wait or complete a task before joining the main lobby. This keeps your main server resources safe while the bots get stuck in the waiting room. 4. Use a Geo-IP Blocker
If you notice the majority of your bot traffic is coming from a specific country where you have no actual players, you can use a plugin like MaxMind or a firewall rule to block those IP ranges entirely. 5. The "White-List" Emergency Switch
Always have a "Panic Button" ready. If an attack is overwhelming your CPU, use a command to toggle a temporary whitelist or increase the connection-throttle in your bukkit.yml. It’s better to have a locked server for 10 minutes than a crashed server for two hours. This blocks an IP after 3 failed logins within 5 seconds
You don't need to pay for premium "Anti-DDoS" services when starting out. By combining a hardened proxy like FlameCord with a smart Anti-Bot plugin, you can repel 99% of common attacks.
If you run a proxy server (BungeeCord / Waterfall / Velocity), bot attacks target the proxy first. Here's how to protect the proxy for free:
Minecraft servers, particularly those with large player bases or competitive gameplay, are frequent targets of bot attacks (DDoS and automated login floods). Many server owners search for “Minecraft bot attack free” solutions to avoid costly mitigation services. This paper examines the nature of these attacks, why truly free protection is rare, the dangers of free “solutions,” and practical low-cost or properly free strategies for legitimate defense.

Forces clients (including bots) to compress packets. Many free bots don't implement compression correctly, causing their connections to fail.
Some forums suggest using free proxy lists to hide the server IP. Risks:
