Vulcan is an advanced cheat detection system that operates at the packet level with version support for 1.7 all the way to 1.18.2.

By default, Vulcan acts silently and does not 'prevent' the player from cheating, but simply observes their actions and flags for things out of the vanilla boundaries (through the configuration certain checks are able to be turned to 'setback' to actively prevent players from cheating)


Support
We have the best support of any plugin on this website, as our hundreds of customers will tell you. Tickets are responded to in minutes (mostly instantly) as long as a staff member is awake. We have staff members in all time zones, ensuring that there is always someone who can help you. False positives and bypasses are fixed within minutes and updates are put out as soon as possible when issues are found. No more waiting months for an update and days for a response from a support team.

Customization
Vulcan has the most extensive configuration file and API of any anti-cheat on this website, and others. Practically every part of Vulcan is configurable, so you can set it up exactly how you want. Our full configuration file can be viewed here.

Simple
No need to spend money on a fancy configuration or an additional addon, Vulcan simply works as-is.


Vulcan has a wide range of features to help quickly identify and remove cheaters from your server.

Client Brand Alerts:
When a player joins the server, they send special messages through plugin channels with the 'brand' of their client.

Spoiler: Note
The Client Brand feature of Vulcan 2.0 allows you to gain insight on what client the player may be using. For example, clients such as Lunar Client will have a client brand such as lunarclient:3d83df6. However, the Client Brand feature cannot tell you which client the player is using, it can only say which client the client says it's using. Hacked client developers are aware of this, and usually, they leave the client brand as Vanilla or Forge or something 'legitimate'. This is not a bug - we simply read what the client says.

In conclusion, a client brand of Vanilla does not mean the player is using a Vanilla client, and a client brand along the lines of Lunar Client may not always be an actual Lunar Client.
Full Alert Customization:
Vulcan allows you to fully customize its alert messages. By default, all sorts of useful information are displayed to staff, such as the player's ping, the server's TPS, the player's client version, a description of the check, and all of the details associated with the flag, with even more placeholders available to you. You are also able to color code your alerts based on how many violations the player has set off!


Advanced Violation and Punishment Logs:
Vulcan's advanced logging system keeps track of all violations and punishments on your server in an easy-to-understand way, while also providing you with plenty of useful information.

Amazing In-Game GUI
Vulcan's amazing in-game GUI allows you to edit any check setting on the fly, even punishment commands.

Spoiler: Checks GUI

Judgment Days
Vulcan's Judgment Day feature allows you to ban players in waves!


Asynchronous
Almost all of Vulcan is run on a separate thread, ensuring that your server's performance is kept at its peak.

The following screenshot is from a 1.16.4 server with 180 players. Vulcan is seen using only 3.47% of the tick, which is not even .02% of a tick per player.

Extensive Configuration
Almost every aspect of Vulcan is configurable, down to the sensitivity and values around each check.
Spoiler: Example Check Configuration

Discord Integration
Vulcan has built-in compatibility to send its alerts and punishments to a configurable discord channel!






Vulcan is compatible with any server version between 1.7 and 1.18.2. We only guarantee full functionality on the following Spigots/forks: Spigot, PaperSpigot, Tuinity, and Purpur. This is not to say that Vulcan will not work on anything except these Spigots, however, they are the only ones in which functionality is 100% guaranteed without any issues.

Known Incompatible Spigots:
- CatServer
- SpigotX (and all of its forks)
- SmokSpigot
If you are unsure as to whether or not Vulcan will work on your particular Spigot, please try using Medusa first as both plugins use the same API for listening to packets: Medusa's Plugin Page

Due to how Vulcan injects into the player's pipeline, some plugins may also cause issues and may not allow for Vulcan to properly inject and listen to the packets sent and received by the player.

May Result in Incompatibilities:
- FastLogin (in some cases)
- Denizen (breaks channeling for some unknown reason)
- SlimeWorldManager

Miscellaneous Incompatibilities:
- Butterfly/Drag Clicking, as well as any other irregular form of clicking or mouse modification. (This includes binding the swing or place keys to anything that is not a left or right-click. We have absolutely no way to distinguish someone who is auto-clicking 35 clicks per second or someone who has bound their attack key to the space bar. Either tell your players not to do this, or disable the auto-clicker checks)
- Non-vanilla movement mechanics
- Client-sided blocks
- Clumsy/any other irregular packet modification
- Attribute modifiers (in versions under 1.13)
- Any non-vanilla client (especially Lunar Client/BlazingPack)
Spoiler: Non-Vanilla Clients
Vulcan is designed to work on the vanilla client. Some 'PvP Clients' such as Lunar Client (along with many others) contain things that alter game mechanics and may result in issues. This is not to say that Vulcan bans everyone who is using Lunar Client, but there are certain instances in which someone who is using a non-vanilla client may be able to false flag something in which a vanilla client would be unable to do so. We would classify these things as 'use at your own risk.' Several large servers such as CubeCraft have outright prohibited the use of clients such as Lunar on their network because of the advantages and issues it causes with their anti-cheat. Any false positives reported from one of these clients will not be accepted.
GeyserMC - Vulcan automatically hooks into Floodgate and identifies Bedrock players and does not flag them (BEDROCK PLAYERS ARE TOTALLY IGNORED). GEYSER SUPPORT/EXEMPTION REQUIRES FLOODGATE-BUKKIT OR ELSE WE HAVE NO WAY OF RESOLVING WHETHER OR NOT A PLAYER IS CONNECTED THROUGH GEYSER. IF YOU ARE ON BUNGEE, YOU NEED TO DO THIS IN ORDER FOR GEYSER SUPPORT TO WORK: https://github.com/GeyserMC/Geyser/wiki/Floodgate

For any questions about any incompatibilities or incompatibilities, please PM me on Spigot or join our Discord.


As with every anti-cheat, there is always the possibility for false positives and bypasses, and Vulcan is no exception. If you experience either of these, please open a ticket with us in our Discord to address your concerns. With that being said, before purchasing Vulcan, please understand Vulcan's purpose. It is designed to detect blatant cheaters who use common and publicly available hacked clients. If you are looking for an anti-cheat that flags people using Vape's Aim Assist, 3.01 reach, and .0001 hitbox expansion, then you are in the wrong place. We like to be as transparent as possible with our users, so here is a list of disclaimers and things that we ask you to acknowledge and keep in mind before purchasing Vulcan.

Spoiler: Some things that Vulcan does NOT detect/have checks for
- Phase (We do not have a dedicated Phase check, but many phase cheats will flag other movement-related checks. This also includes VClip)
- Vanilla NoSlow/Eating while Running (Server/Client desync, easily able to be false flagged)
- Right click autoclickers
- Sprinting while Sneaking (Vanilla) Packet based sneaks are detected)
- InventoryWalk (Desync, protocol limitations on higher versions)
- Geyser players are completely ignored
- X-Ray (This is a client sided cheat, you cannot detect this on the server-side. Use PaperSpigot's built-in anti-xray)
- Blink (Literally simulates a laggy player dropping connection, not detectable without banning anyone who lags, please see )
Spoiler: Detection Disclaimers
Spoiler: Auto Clicker
While Vulcan's auto-clicker checks are rather advanced, some auto-clickers are extremely advanced and click in a way in which they are almost indistinguishable from a normal human being and will inevitably not be detected. Depending on the settings, things such as Vape and Vape Lite's auto clicker have been proven to flag after an adequate amount of time has passed.
Spoiler: Kill Aura
Similar to auto-clicker, some Kill Aura's aim in a way that is almost identical to that of a normal human and normal client. Despite this, Vulcan's Kill Aura detects are very advanced and will detect the vast majority of Kill Auras given that an adequate amount of time has passed. Additionally, please acknowledge that some Kill Aura and Aim checks may only function when players are actively fighting, and some may not work against monsters or animals. Any Kill Aura that may “bypass” will not provide a significant advantage as they will be limited due to reach and keep-sprint detections. It is impossible to detect every single kill aura.
Spoiler: Scaffold
Similar to Kill Aura and Auto Clicker, some Scaffold cheats will bridge in a way that is possible by legitimate players. Because of stability reasons, this may go undetected as it's not possible for us to accurately distinguish between someone using these 'cheats' and someone who is simply good at bridging. Any scaffold that provides a significant advantage will be detected. We have checks such as Scaffold (Type K) which simply check if a player has placed more than X blocks per second.
Spoiler: Elytra Fly
Trying to determine when someone is flying illegitimately when they are literally allowed to fly is no easy task. We are constantly improving our elytra checks, however, there is a limit as to what can be detected. Additionally, please note that wearing an elytra may degrade the function of other checks due to high occurrences of desync.
Spoiler: Reach/Hitbox
The Reach/Hitbox checks may only work on actual players and work best while in active combat with another player.
Spoiler: Blink
Some Blink modules may go undetected as they perfectly replicate a player who has simply 'lagged out', however, any illegal actions performed by the player while they are using said module will still result in them being flagged normally.
Spoiler: No Slow
Some NoSlowdown modules may only block the sword on the client's screen, which may give the illusion that it may be bypassing when in reality the player is only blocking on their own screen. Also keep in mind that there is no 'sword blocking' on 1.9 and higher servers as it is replaced by shields so the checks will not work on these versions, however on 1.8 they are blocked.
Spoiler: Velocity
For obvious reasons, Velocity checks may cease to function when the player is under a block or against a wall or other non-solid blocks such as ladders.
Spoiler: Wall Climb
This check may fail to function properly when the player is on and/or near a climbable block, such as a ladder or vine (in some cases, liquids, or other non-solid blocks). Due to the nature of how players may sometimes be able to glitch into blocks, this check is advised to be set to setbacks only and not to punish for.
Spoiler: Jesus
These functions of these checks may be limited or they may not function at all when a player is too close to solid blocks, or when the water may be flowing. Some Jesus checks may not function if the player's client version is higher than 1.13 but the server is not. The player can still 'swim' client-sided, therefore the checks cannot be run in this instance.
Spoiler: Miscellaneous Disclaimers
Spoiler: Cancelled Block Placements/Ghost Blocks
While we do our best to account for these, in some cases it is near impossible. Ghost blocks/ghost water are extremely difficult to account for as they are entirely client sided. For this reason, we recommend setting areas with canceled block placements to adventure mode in order to prevent players from creating ghost blocks or ghost liquids.
Spoiler: Non-Vanilla
Clients Vulcan is designed to work on the vanilla client. Some 'PvP Clients' such as Lunar Client (along with many others) contain things that alter game mechanics and may result in issues. This is not to say that Vulcan bans everyone who is using Lunar Client, but there are certain instances in which someone who is using a non-vanilla client may be able to false flag something in which a vanilla client would be unable to do so. We would classify these things as 'use at your own risk.' Several large servers such as CubeCraft have outright prohibited the use of clients such as Lunar on their network because of the advantages and issues it causes with their anti-cheat.
Spoiler: Spigot Forks
Vulcan is only guaranteed to work on the following: Spigot, PaperSpigot, and Tuinity. This is not to say that Vulcan will not work on any other Spigot Fork, but these are the only ones where its function is 100% guaranteed. Known Incompatibilities:mSpigot (and all it's forks), CatServer, aSpigot, SpigotX (and all of its forks)
Spoiler: Non-Vanilla Movement/Special Abilities/Artificial Movement
Vulcan is designed to work with Vanilla movement mechanics. While we do our best to account for every scenario, we cannot guarantee there won't be any issues if you have plugins that differ drastically from normal movement. The only thing we can guarantee is that plugins that allow players to fly will not cause false flags. We have an extensive Developer API that can allow you to make Vulcan work with any of your special plugins.
Spoiler: Version Compatibility
Because of changes in the Minecraft Protocol, some predominately packet-based checks are hard-coded disabled on the newer server and client versions. This will not affect gameplay in any major way and is done for stability purposes.

Download Vulcan.
Place into your plugins folder.
Restart the server.

Vulcan is not compatible with /reload or PlugMan (/plugman reload | /plugman load) - these will cause errors. Please restart the server, or use the /vulcan reload command.

Any check marked with a * in game is EXPERIMENTAL, meaning you SHOULD NOT PUNISH FOR THEM. They are not yet fully stable and still in development

Every server is different, and some may require different configurations. Vulcan is made in a way that allows you to modify the sensitivity and values for almost every single check - please make use of this for your server.

For example, if you're running a KitPvP server, you can probably disable the Fast Break and Baritone checks, as they aren't necessary at all in that game mode. Gamemodes that run for a shorter duration of time such as SkyWars or Bedwars may benefit from lowering the max-violations for some checks in order to punish players more quickly.
