What is MC-World-MCP copilot-instructions.md?

Repository instructions for mc-world-mcp, an offline-only server that works with Minecraft Java world files. They describe how to use Minecraft reference and local-world tools safely.

Use them when diagnosing or editing Minecraft worlds, datapacks, world generation, commands, or server data.

They provide the checks and workflow needed before changing a world, including version, server, datapack, and offline-safety checks. This reduces the risk of applying invalid commands or unsafe changes.

Token cost

What it costs to keep this loaded

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	$0.00789	$0.00789
Opus 5.5	$0.00316	$0.00316
Sonnet 5.5	$0.00158	$0.00158
Haiku 4.5	$0.00079	$0.00079

Security

Grade A, and why

MC-World-MCP copilot-instructions.md 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 2mo 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.

Copilot / Assistant Instructions

This repository provides mc-world-mcp, an offline-only MCP server for Minecraft Java / Arclight 1.20.1 world files.

Before planning or editing meaningful work, read the project README and Copilot repo memory if available. Useful memory topics include project overview, datapacks, tools, technical gotchas, change history, and MCP server notes.

MCP Servers

Use minecode for Minecraft reference data:

Commands: get_wiki_command_info, then spyglass_get_commands for exact syntax.
IDs and registries: spyglass_get_registries.
Vanilla JSON: Misode tools such as misode_get_preset_data, misode_get_presets, misode_get_loot_tables, and misode_get_recipes.
Wiki pages: search_wiki, then get_wiki_page_content.

Use mc-world for local server/world operations:

First read the MCP-provided server instructions. If unsure, call assistant_instructions() or read the mc-world://assistant-instructions resource.
Start with server_summary(), detect_world_version(), world_summary(), and check_offline_safety().
Diagnose datapacks with list_datapacks(), validate_datapacks(), worldgen_report(), validate_worldgen_references(), search_datapack_files(), and read_datapack_file().
Inspect logs with analyze_latest_log(), read_server_log(), and grep_server_log().
Inspect Anvil data with scan_regions(), scan_world_coverage(), inspect_chunk(), summarize_chunk_palette(), get_block(), and read_block_box().
Edit offline with focused tools such as write_datapack_file(), write_nbt_value(), write_chunk_nbt_value(), set_block(), fill_blocks(), replace_blocks(), set_biome_box(), add_block_entity(), and add_entity().
Preview with render_map_preview(), render_slice_preview(), and render_template_preview().

Safety Rules

Never use RCON, sockets, online player queries, or server start/stop controls from this MCP workflow.
Reads may run while the server is online.
Writes require the server to be offline; mc-world rejects writes while server or unknown java/javaw processes are running, while recognized Minecraft client Java processes are ignored.
World writes are supported only for Java Anvil DataVersion 3465.
Every write creates backup/mc_world_mcp/<timestamp>/manifest.json.

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.
