Scraft is a Minecraft mod inspired by Screeps that turns your server into a bot programming environment. Users log in and generate API keys, which allows them to log in as bot users in their code. Only bots are allowed on the server - human players are placed in spectator mode to observe the bots' actions. (While there is nothing stopping a user from implementing the login flow on a normal Minecraft client and playing normally, it is discouraged.)
This mod works best with the following configurations:
- Disable chat signing with
enforce-secure-profile=falsein your server.properties. - Enable a whitelist.
- Setting up a domain with wildcard DNS, which is supported by providers like Cloudflare. Make two DNS records,
scraft.example.comand*.scraft.example.com, pointing to the same server.
Whitelisted players can join the server and will be placed in spectator mode. They can then run /scraft apikey to generate an API key.
To join as a bot, connect to the domain scraft_(api key).scraft.example.com, or you can fabricate the hostname in the handshake packet if you wish. No authentication is required - you can pick any username, so long as it is not claimed by another user.
Bot names will be claimed automatically on join, or you can run /scraft claimuser to claim a username. One user can hold up to 10 bot names, and bot names can be released with the /scraft dropuser command. Bots will have their names prefixed with the + character to indicate they are bots.
If you remove a user from the whitelist, you will need to remove their API key and bot as well (currently only possible through manual database editing).
