name: building-redstone description: Builds redstone circuits, mechanisms, and automation in Minecraft using VibeCraft MCP tools. Use when building logic gates, memory circuits, piston doors, automatic farms, item sorters, clocks, or any redstone contraption.

Building Redstone

Critical: Block Placement Order

Support blocks FIRST, then dependent blocks! Blocks drop as items if support doesn't exist.

CopyWRONG: 1.wire 2.button 3.blocks → Wire breaks!
RIGHT: 1.platform 2.walls 3.wire 4.button

Attachment Rules

Wall attachment facing: east→block at X-1, west→X+1, north→Z+1, south→Z-1

MCP Tools

Copybuild(commands=[
    "/fill X Y Z X2 Y Z2 stone",           # 1. Support
    "/setblock X Y+1 Z redstone_wire",     # 2. Redstone
    "/setblock X+1 Y+1 Z stone_button[facing=west,face=wall]",  # 3. Attachments
])

Logic Gates

NOT: [in]→[block]→[torch]→[out] — Torch inverts signal OR: Merge two wires at same block AND: Two torches→junction block→inverting torch→output XOR: Two comparators in subtract mode, OR their outputs

See gates.md for implementations.

Memory Circuits

RS Latch: Two torches in feedback loop (Set/Reset) T Flip-Flop: [in]→[dropper↔dropper]→[comparator]→[out] — Toggles state

Timing

Repeater Clock (3 minimum):

Copybuild(commands=[
    "/setblock X Y Z repeater[facing=east,delay=1]",
    "/setblock X+1 Y Z repeater[facing=south,delay=1]",
    "/setblock X+1 Y Z+1 repeater[facing=west,delay=1]",
    "/setblock X Y Z+1 redstone_wire",
])

Hopper Clock: [hopper→hopper] with comparator. Timing = items × 0.4s

Piston Door (2x2)

Copybuild(commands=[
    "/setblock X Y Z stone_bricks",
    "/setblock X Y+1 Z stone_bricks",
    "/setblock X-1 Y Z sticky_piston[facing=east]",
    "/setblock X-1 Y+1 Z sticky_piston[facing=east]",
    "/setblock X-2 Y Z redstone_wire",
    "/setblock X-2 Y+1 Z redstone_wire",
])

Block States

Copyrepeater[facing=north,delay=1-4,locked=false]
comparator[facing=south,mode=compare|subtract]
piston[facing=up,extended=false]
sticky_piston[facing=east,extended=true]
observer[facing=north]  # watches that direction
lever[face=wall,facing=north]
stone_button[face=wall,facing=east]

Farms

See farms.md for: sugar cane, pumpkin/melon, chicken, iron, crop, mob, item sorter, wool, honey farms.
