FishChecker: Global Ban Check Plugin for Minecraft Servers
Every Minecraft server administrator knows the pain of dealing with unwanted guests. Griefers, cheaters, and toxic players can ruin the experience for everyone, and manually vetting every newcomer is a tedious, time-consuming process. Standard server tools often lack the depth needed to see the full picture of a player's history. This is where the FishChecker plugin steps in, offering a streamlined solution that connects your server to the global FishBans database. This lightweight tool automates reputation checks, pulling data from multiple ban systems, and gives you the intelligence you need to make informed decisions before a troublemaker can cause any damage.
Understanding the Core Purpose of FishChecker
FishChecker is a compact plugin designed for servers running on Bukkit and its popular forks, such as Spigot and Paper. Its primary function is to act as a bridge between your Minecraft server and the FishBans API. When a player joins, or when you manually trigger a check, the plugin sends a request with the player's username to FishBans. In the background, it receives a comprehensive summary of all known bans associated with that account. The entire process is silent and efficient, requiring no complex configuration. It simply works in the background to enhance the security of your world, providing a transparent layer of protection without adding unnecessary overhead to your server's performance.
The Foundation: How the Global FishBans System Works
To truly appreciate the plugin, you need to understand the service it relies on. FishBans is not a single ban list; it is an aggregator. It collects ban data from a wide array of popular sources, including McBans, MCBlockIt, MCBouncer, Minebans, New Glizer, and several others. When you request information on a player, the service queries all connected databases simultaneously and returns a unified report. This multi-source approach is crucial because it prevents a scenario where a known offender is banned on one platform but appears completely clean on another. Essentially, FishBans provides a comprehensive "credit history" for players within the Minecraft ecosystem, offering a far more complete picture than any single ban list could provide.
It is important to note that FishBans does not issue its own verdicts. It simply aggregates facts from various sources. The final decision on whether to allow or block a player always rests with the server administrator. FishChecker's role is to deliver this valuable information directly into your game chat or server console, eliminating the need to open a browser and manually type a username into the FishBans website. This seamless integration is what makes the plugin so practical for busy server admins.
Key Features and Capabilities
The developers of FishChecker have focused on simplicity and automation. Here is a breakdown of what the plugin can do right after installation:
- Automatic Check on Player Join: As soon as a player connects to your server, the plugin silently sends a query to FishBans. Depending on your configuration, it can alert the administration team in the chat or console, or even display the information to the player themselves.
- Forced Search for New Players: If an account has not yet been indexed by the FishBans service, the plugin can initiate a forced data collection request. This ensures that the database remains up-to-date and that you get the most current information available.
- Flexible Permission System: FishChecker integrates with standard permission managers, allowing you to finely control who has access to commands, who can view messages, and who has the ability to override automated checks. This allows you to create distinct roles for moderators, admins, and regular players.
- Manual Check Command: At any time, you can execute a check via the console or in-game chat using the
/fishcheck [playername]command. This provides an instant summary and is particularly useful for verifying a player who is already on the server or for double-checking someone who hasn't logged in for a while.
Installation and Configuration Guide
Installing FishChecker is a standard procedure for any Bukkit-based server. You simply need to place the plugin's JAR file into your server's plugins folder and restart the server. Upon the first launch, the plugin will generate a configuration file. This file allows you to customize several key aspects of its behavior, such as which groups of players receive notifications, which ban sources should be considered a priority, and whether the plugin should automatically kick players who have a certain number of bans recorded against them.
Setting Up Permissions
Properly configuring permissions is essential for a smooth experience. By default, FishChecker adds several permission nodes that you can assign through a permissions plugin like LuckPerms. Here are the main ones:
fishcheck.command: This grants the ability to use the/fishcheckcommand.fishcheck.messages: This allows a user to see ban notification messages when other players join the server.fishcheck.alertself: This gives a player the option to see their own warnings when they connect to the server.fishcheck.override: This is a powerful privilege that allows a user to bypass automatic blocks, which is essential for server administrators who might be flagged by a false positive.
By thoughtfully assigning these permissions, you can build a multi-layered notification system. For example, your junior helpers might only see basic flags, while your senior administrators have access to the complete ban history for any player. This ensures that the right people have the right information at their fingertips without overwhelming the entire staff team.
Commands and Practical Use Cases
The plugin features a single, user-friendly command: /fishcheck {player}. This command outputs a list of services where the username has been seen, along with the number of bans and text-based identifiers for more details. This is perfect for a quick check on a suspicious player without having to leave the game. While the automatic check on join handles most of the heavy lifting, the manual command remains invaluable for re-verifying a long-absent user or checking someone who is already active on your server. Some creative administrators even write simple scripts that periodically run /fishcheck on all online players and log the results, creating a dynamic reputation map of their community over time.
