SecurityCraft Mod (26.1, 1.20.6) – Decorative Blocks & Details

SecurityCraft is a Minecraft mod that adds Adds plenty of blocks and items to defend and secure your base with. for NeoForge on Minecraft 26.1 to 1.21.7.

SecurityCraft solves a practical modpack problem: you get a focused feature upgrade without having to guess whether the project is actively used or whether it supports your loader. With 2,909,906+ Modrinth downloads, this is not a hidden prototype; it is a mod many players have already tried, which makes it easier to justify testing in a real world or staging server. Features Ownership Every block in the mod is owned by one specific player, the "Owner". The owner is the player who placed down the block. Only the owner of a block can interact with it, and only the owner can break it. Many blocks ignore their owner, meaning their functions do not apply to the owner, but only to other players. This behavior can be turned off per block in the screen that opens when rightclicking the block with a Universal Block Modifier. There is optional support for scoreboard team ownership, which can be enabled in the config. This results in every player on a team owning all blocks that were placed by a player who is also on that same team.\ If you have a mod like Jade or The One Probe installed, you can see who owns a block in that mod's overlay. Reinforced Blocks SecurityCraft adds reinforced blocks corresponding to many of the already existing vanilla blocks. These reinforced blocks are unbreakable variants of their vanilla counterpart, and have a slightly darker tint to distinguish them from, but otherwise look the same as, their vanilla versions. This tint can be turned off in the config file. Reinforced blocks are immovable by vanilla pistons, however they

How to Install SecurityCraft

1. Check whether your instance uses Fabric, Forge, NeoForge, or Quilt, then pick the matching file from the download table.
2. Back up your world and server configs before adding SecurityCraft, especially if the mod changes gameplay systems, entities, structures, or progression.
3. Drop the downloaded .jar into your mods folder, keep required dependencies aligned with the same Minecraft version, and avoid mixing loader builds.
4. Launch Minecraft once, verify that SecurityCraft appears in your mod list, and open a test world to confirm startup and basic behavior.
5. For multiplayer, install the mod on the side required by its compatibility flags, restart cleanly, and test with a non-production world before rolling it out.

Frequently Asked Questions
