Setup minecraft world

Create the world and install the behavior pack (Step 2 of 4)

This is Phase 2 of the four-phase Minecraft Bedrock MCP setup. It assumes Phase 1 (setup-bedrock-server) is done: BDS is unzipped, has run once, and is currently stopped.

Work interactively — confirm each step before the next. BDS must stay stopped throughout; you are editing files inside its world folder.

Why the world must be created in the Minecraft client

The behavior pack needs the Beta APIs experiment. That toggle can only be set when a world is created in the Minecraft client — the dedicated server cannot enable it, and it travels with the world afterward. So the user creates the world on a PC/device, then moves it to the server.

Confirm the user has Minecraft: Bedrock Edition on a PC or device.

Step 1 — Create the world in the Minecraft client

In Minecraft: Bedrock Edition, choose Create New World and set:

Setting	Value	Why
Game Mode	Creative	Agents place/break blocks and spawn entities freely.
Cheats (Activate Cheats)	On	Enables commands; pairs with allow-cheats on the server.
Experiments → Beta APIs	On	Required. @minecraft/server-net / -admin are beta modules.

Have the user give the world a clear name. Then play the world once for a few seconds so it is fully written to disk, and exit.

Step 2 — Export the world

In Minecraft, on the worlds list, open the world's settings (the pencil icon) and choose Export World. This produces a .mcworld file — which is just a ZIP archive under a different extension.

Have the user copy that .mcworld file to the BDS host (scp, a USB drive, a file share — whatever fits their setup from Phase 1).

Step 3 — Transfer the world into BDS

Pick a folder name for the world under <bds>/worlds/ — mcp-world is a good default. Unzip the .mcworld into it.

Linux:

cd /opt/bedrock-server/worlds
mkdir "mcp-world"
unzip ~/exported-world.mcworld -d "mcp-world"

Windows (PowerShell): rename the file to .zip (or use Expand-Archive directly), then:

$dest = "C:\bedrock-server\worlds\mcp-world"
New-Item -ItemType Directory -Force $dest
Expand-Archive -Path "$HOME\Downloads\exported-world.mcworld" -DestinationPath $dest

Verify the world folder directly contains level.dat and a db/ folder (not a nested subfolder). If it's nested one level deep, move the contents up.

Now set level-name in <bds>/server.properties to the folder name:

level-name=mcp-world

Record the world's absolute path — e.g. /opt/bedrock-server/worlds/mcp-world or C:\bedrock-server\worlds\mcp-world. Phase 3 needs it.

Step 4 — Get the behavior pack

The behavior pack is the bedrock-bridge pack from a separate repository: https://github.com/chapmanjw/minecraft-bedrock-mcp-behavior-pack

Two ways to get it:

• Download bedrock-bridge.mcpack from that repo's Releases. An .mcpack is just a ZIP — unzip it to get the pack folder.
• Build it — clone the repo and run npm install && npm run build.

Either way, the pack is the folder containing manifest.json, scripts/main.js, and pack_icon.png. If the local clone is on this machine (it may be a sibling folder of this plugin repo), you can use it directly.

Keep the pack version aligned with the BDS version and the MCP server version — the experimental Script API requires the three to move together.

Step 5 — Install the pack into the world

Place the pack folder at <world>/behavior_packs/bedrock-bridge/.

Linux:

mkdir -p "/opt/bedrock-server/worlds/mcp-world/behavior_packs"
cp -r bedrock-bridge "/opt/bedrock-server/worlds/mcp-world/behavior_packs/"

Windows (PowerShell):

$bp = "C:\bedrock-server\worlds\mcp-world\behavior_packs"
New-Item -ItemType Directory -Force $bp
Copy-Item -Recurse .\bedrock-bridge $bp

Step 6 — Activate the pack on the world

Create (or edit) <world>/world_behavior_packs.json so BDS loads the pack:

[{ "pack_id": "fa013817-66f2-4a5f-a724-1347f912bd40", "version": [0, 2, 0] }]

pack_id is the pack's header UUID — use exactly the value above. If the pack you downloaded reports a different version in its manifest.json, match the version array to it.

Record the pack's absolute path — e.g. <world>/behavior_packs/bedrock-bridge. Phase 3 needs it too.

Wrap up

Confirm with the user:

• World created in the Minecraft client with Beta APIs, Creative, and Cheats on; played once.
• World exported and unzipped under <bds>/worlds/, with level.dat at its top level.
• level-name in server.properties points at the world folder.
• bedrock-bridge pack folder is at <world>/behavior_packs/bedrock-bridge.
• world_behavior_packs.json exists with the pack UUID.
• World path and behavior-pack path are written down.

Hand off: Phase 2 is done. The next step installs and configures the MCP server and starts everything. Offer to continue with the setup-mcp-server skill now.
