You cannot legitimately find a world seed without access to the server/client seed data or explicit permission from the server owner
Ask the server owner or admin for the seed
Check if the server has a public map, website, or Discord where the seed is shared
If you own the world, use the game’s built-in world settings or save files to view the seed
If you are on a single-player world, open the world’s save data or world info to retrieve the seed
Use server-provided commands or plugins only if you have permission
Do not use unauthorized seed-finding methods on servers you do not own or administer
