Auto block crafter mod

Auto-Craft
Compress your inventory automatically — without ever opening it.

Snowballs piling up? Quartz eating six stacks? Auto-Craft watches your inventory and quietly turns loose materials into blocks the moment you cross a threshold you choose. No screen opens. No clicking. Nothing interrupts what you were doing.

How it works
Your 2×2 crafting grid lives in the same container the server keeps open for you at all times — pressing E doesn't send a single packet, which means the server has no idea whether your inventory screen is actually on your monitor.

Auto-Craft uses that. It drives the grid with exactly the packets your mouse would send, so every craft is a normal, server-validated vanilla craft. Nothing is faked client-side, and your items are really there when you relog.

That's also why it's client-side only — it works on vanilla servers with nothing installed on their end.

Features
67 recipes, not two
Every 2×2 single-material recipe in the game, pulled straight from Minecraft's own recipe data:

19 compressions — snowballs, nether quartz, clay balls, bricks, nether bricks, glowstone dust, prismarine shards, amethyst shards, honeycomb, magma cream, pointed dripstone, resin bricks, sand, red sand, popped chorus fruit and more. The ones that actually save you space.
26 building conversions — stone → stone bricks, granite/diorite/andesite/tuff/blackstone → polished, cobbled deepslate → polished, copper block → cut copper, end stone → end stone bricks, packed mud → mud bricks.
22 log → wood recipes — included for completeness, clearly marked, and off by default, because four logs only give you three wood.
Enable as many as you like
Run snowballs, quartz and clay at once. Each recipe gets its own threshold, which matters more than it sounds: 256 snowballs is sixteen stacks, but 256 quartz is only four.

A settings screen that doesn't look like 2011
Flat, dark and modern — built from scratch rather than bolted together from vanilla buttons. Searchable, filterable by category, with an item icon and live toggle on every row.

A HUD that tells you what's happening
A small readout in the corner showing what's enabled and what's next — Snowball 143 / 256 while it fills up, Crafting Snow Block… 32 made while it works. Toggle it off if you'd rather not see it.

Built to recover, never to give up
It will not silently die on you. Server lag, a dropped packet, a recipe the server won't allow — it backs off and retries instead of switching itself off, and it sweeps the crafting grid every tick so items can never get stranded in it.

Controls
Key Action
N Toggle auto-crafting on/off
G Open settings
Both are rebindable in Options → Controls → Inventory.

Auto-crafting always starts off when you launch the game — it never surprises you after a restart. Your recipes and thresholds are remembered.

Please read before using on a server
This is an automation mod. Every packet it sends is one vanilla would send, but:

Some servers' anti-cheat may flag rapid inventory clicks. There's a pacing setting in the config to slow it down.
Some servers' rules prohibit automation mods. Check before you use it, and respect the answer.
It's client-side, so it will never stop you joining a server — but that's not the same as being allowed to use it there.
