ServerTap

ServerTap is a REST API for Bukkit, Spigot, and PaperMC Minecraft servers. It allows for server admins to query and interact with their servers using simple REST semantics.

This plugin is under development and is not ready for real usage yet.

But if you're feeling brave, head over to https://github.com/phybros/servertap/releases to grab the latest and greatest plugin JAR.

Usage

Install this plugin by dropping the jar into the plugins/ directory on your server.

Then, you can query the server using curl or Postman, or anything that speaks HTTP.

For example, query for information about the server itself:

$ curl http://localhost:4567/v1/server

{
  "name": "Paper",
  "motd": "This is my MOTD",
  "version": "git-Paper-89 (MC: 1.15.2)",
  "bukkitVersion": "1.15.2-R0.1-SNAPSHOT",
  "health": {
    "cpus": 4,
    "uptime": 744,
    "totalMemory": 2010644480,
    "maxMemory": 2010644480,
    "freeMemory": 1332389360
  },
  "bannedIps": [],
  "bannedPlayers": [
    {
      "target": "phybros",
      "source": "Server"
    }
  ]
}

Or get a list of players that are currently online:

$ curl http://localhost:4567/v1/players

[
  {
    "uuid": "55f584e4-f095-48e0-bb8a-eb5c87ffe494",
    "displayName": "phybros",
    "address": "localhost",
    "port": 58529,
    "exhaustion": 3.5640976,
    "exp": 0.45454547,
    "whitelisted": false,
    "banned": false,
    "op": true
  }
]

Current Endpoints

This plugin self-hosts its own API documentation using Swagger. You can see the full API documentation at http://your-server.net:4567/swagger. You can even explore and test the API right from the UI!

Note: there is a known issue that causes the OpenApi plugin to spew tons of logs into your server log. See servertap-io#60 for details.

Some examples of capabilities are:

• Ping
• Server
  • Get/Add/Remove Ops
  • Get/Add Whitelist
• Get/Save/List Worlds
• List/Read Scoreboard(s)
• Broadcast
• List/Find Players
• Get/Pay/Debt Economy (W/ Plugin)
• List Plugins

Authentication

Authentication is very rudimentary at this point. Add this to your plugins/ServerTap/config.yml file:

useKeyAuth: true
key: some-long-super-random-string

Then include a Header called key with your specified key on every request to Authenticate.

We need help making this better! See servertap-io#5 for more info.

Webhooks

ServerTap can send webhook messages in response to events on the server.

To use webhooks, just define them in your plugins/ServerTap/config.yml file like so:

webhooks:
  default:
    listener: "https://your-webhook-target.com/whatever"
    events:
    - PlayerJoin
    - PlayerQuit

The webhook requests are POST containing a simple JSON payload:

{
  "player": {
    "uuid": "55f584e4-f095-48e0-bb8a-eb5c87ffe494",
    "displayName": "phybros",
    "address": "localhost",
    "port": 52809,
    "exhaustion": 0,
    "exp": 0.5714286,
    "whitelisted": true,
    "banned": false,
    "op": true
  },
  "joinMessage": "§ephybros joined the game",
  "eventType": "PlayerJoin"
}

The available events are currently:

• PlayerJoin
• PlayerDeath
• PlayerChat
• PlayerKick
• PlayerQuit

Developing

You need a few things to get started

• An IDE (e.g. IntelliJ)
• JDK 8 (soon to be 11)
• Maven

Then, you can build the plugin jar by using the mvn package command.
