What is Vault in Minecraft and do you need it

Many plugin pages say "requires Vault". Vault does not do anything visible by itself. It is a bridge that lets plugins from different authors work together.

What it connects

• Economy: a shop plugin can charge money without knowing which economy plugin you installed.
• Permissions: a plugin can ask "may this player do that" no matter which permissions plugin you use.
• Chat: prefixes and suffixes from a chat plugin can be read by others.

How it is used

You install Vault and one plugin that provides an economy. Every plugin that supports Vault then uses that economy automatically. Without Vault, each plugin would need its own list of supported economies.

Do you need it

• If you use plugins that say they need Vault for money or ranks, yes.
• If you only run a few self-contained plugins, no.
• If you generate a plugin and want it to play well with others, ask for Vault support as an optional extra.

Optional means optional

A well-written plugin treats Vault as a soft dependency: it uses Vault when it finds it and otherwise falls back to its own simple version. That way the plugin still starts on a server without Vault.

Newer alternatives

Some modern economy plugins offer their own API and some permission plugins such as LuckPerms have a rich API of their own. Vault is still the most widely supported bridge, so it remains the safe default.

A typical setup with Vault

A server installs Vault, an economy plugin, a shop plugin and a permissions plugin. The shop asks Vault for the economy and charges the player. The chat plugin asks Vault for the prefix of the player. None of these plugins needs to know about the others directly, which is the whole point of Vault.

Signs that you need it

• A plugin page lists Vault as a required dependency.
• The console says a plugin could not find an economy provider.
• Players have money in one plugin but cannot spend it in another.

Frequently asked questions

Does Vault work on new versions?

Vault is widely used and kept working on current Paper versions. Check its page for the latest status before you update.

Is Vault an economy itself?

No. It connects plugins. You still need a plugin that provides the economy.

Can the generated plugin use it?

Yes, when you ask for it. The generated code treats Vault as optional, so the plugin starts even if Vault is missing.
