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 | $0.00088 | $0.01842 |
| Opus 5 | $0.00044 | $0.00921 |
| Sonnet 5 | $0.00018 | $0.00368 |
| Haiku 4.5 | $0.00009 | $0.00184 |
Grade A, and why
setup-mcp-server scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 193 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Install and run the MCP server (Step 3 of 4)
This is Phase 3 of the four-phase Minecraft Bedrock MCP setup. It assumes
Phase 2 (setup-minecraft-world) is done. You should have, written down:
- the world path, e.g.
/opt/bedrock-server/worlds/mcp-world - the behavior-pack path, e.g.
<world>/behavior_packs/bedrock-bridge
If either is missing, get it before continuing. The MCP server runs on the
same host as BDS and needs Node.js 20+ there — verify with node -v.
How the pieces talk
The MCP server exposes two authenticated surfaces:
/mcp— what Claude connects to (Phase 4), guarded byBRIDGE_CLIENT_TOKEN./bridge— what the behavior pack long-polls, guarded byBRIDGE_AGENT_TOKEN.
So there are two separate tokens. Keep them straight: the client token is for Claude, the agent token is for the behavior pack inside the world.
Step 1 — Install the MCP server
On the BDS host:
npm install -g minecraft-bedrock-mcp-server
Alternatives, if the user prefers: npx minecraft-bedrock-mcp-server (no
install), or the Docker image
ghcr.io/chapmanjw/minecraft-bedrock-mcp-server:latest (docker run --env-file .env -p 8765:8765 ...). Pin to a version tag for reproducibility, and keep it
aligned with the BDS and behavior-pack versions.
Step 2 — Generate the two tokens
Generate two long random secrets:
openssl rand -hex 32 # -> BRIDGE_CLIENT_TOKEN
openssl rand -hex 32 # -> BRIDGE_AGENT_TOKEN
On Windows without openssl:
-join ((1..32) | ForEach-Object { '{0:x2}' -f (Get-Random -Max 256) })
Have the user keep both values somewhere safe. They are needed again in this phase and in Phase 4.
Step 3 — Write the MCP server .env
Create a .env file for the MCP server (this plugin ships .mcp.json.example
in its repo root as a reference, but the server's own .env is what matters
here):
BRIDGE_CLIENT_TOKEN=<first secret>
BRIDGE_AGENT_TOKEN=<second secret>
BRIDGE_WORLD_PATH=<the world path from Phase 2>
BRIDGE_BEHAVIOR_PACK_PATH=<the behavior-pack path from Phase 2>
BRIDGE_HOST=0.0.0.0
BRIDGE_PORT=8765
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-mcp-server is a skill published in the GitHub repository chapmanjw/minecraft-bedrock-claude-plugin (2 stars, last pushed 1mo ago), licensed MIT. It adds 88 tokens to every session and 1,842 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
