the tab you asked for

Three tools built around anarchy / SMP play where the map is loaded, the bases are buried, and everybody owes somebody blocks.

  • SusChunkFinder — scans nearby chunks for spawners, loot and dense block-entity clusters. Chat pings on first find.
  • ChunkFinder — diffs loaded chunks per tick. See when somebody else pushes new terrain, or when a vein leaks into render.
  • AutoBuilder — point at a schematic, give it an origin, let it place from your hotbar on survival. Reach-safe, inventory-aware, resumes on kick.

// FAQ man astra
is this undetected on vulcan?

Not forever. Vulcan updates weekly. We ship humanized defaults (RotationLimit, HumanizedRandom, GCD snap, AttackRangeTimer) and we publish a per-server module risk sheet in Discord. On default settings, combat + visual tabs are safe on 1.21 Vulcan. Movement tab is not — leave Speed, Scaffold, SnapTap off on anticheat servers.

do i need forge?

No. Fabric only. We don't ship a Forge build.

will it work on 1.21.9 or 1.21.10?

Current jar targets 1.21.11. Legacy builds for 1.21.10 and 1.21.9 live in the lifetime-only channel on Discord.

what schematic format does autobuilder read?

Sponge .schem. Litematica .litematic support is in the 3.1 branch. Drop files in .minecraft/config/mochi/schematics/ and point AutoBuilder at the filename.

refunds?

Full refund within 48h if the jar won't launch on a clean Fabric install of its target MC version. No refunds for bans, server-specific issues, or skill gaps.

who is this for?

SMP regulars who want combat that doesn't fumble, builders tired of placing 1800 blocks by hand, and chunk nerds who want to see when the map changes around them. If you're expecting a one-click "win the game" button, keep walking.

not affiliated with mojang / microsoft. use on your own accounts.
every server has its own rules — read them before you boot the jar.
