Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00074 | $0.01496 |
| Opus 5 | $0.00037 | $0.00748 |
| Sonnet 5 | $0.00015 | $0.00299 |
| Haiku 4.5 | $0.00007 | $0.00150 |
Grade A, and why
setup-minecraft-world scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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"
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

setup-minecraft-world is a skill published in the GitHub repository chapmanjw/minecraft-bedrock-claude-plugin (2 stars, last pushed 1mo ago), licensed MIT. It adds 74 tokens to every session and 1,496 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
