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.

Security

Grade A, and why

minecraft-mod-mcp-helper 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 8d 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.

Workflow

Phase 1 — FTB Quests 任务书生成

步骤 1:生成章节 ID 和分组

调用 generate_hex_id 生成 16 位随机十六进制 ID:

{}

返回 { "id": "A1B2C3D4E5F6G7H8" }

调用 generate_chapter_group_snbt 生成章节分组配置:

{
  "groups": [
    { "id": "MAIN000000000001", "title": "§l&6主线任务" },
    { "id": "SIDE000000000001", "title": "§l&a支线任务" }
  ]
}
步骤 2:生成章节内容

调用 generate_quest_chapter 生成完整章节:

{
  "title": "初入世间",
  "group_id": "723AE4EA49A6043A",
  "icon": "minecraft:writable_book",
  "order_index": 0,
  "filename": "00_prologue",
  "quest_count": 3
}

返回结构:

{
  "chapter_id": "A1B2C3D4E5F6G7H8",
  "filename": "00_prologue.snbt",
  "content": "{ ... SNBT 内容 ... }",
  "quest_count": 3,
  "quest_ids": ["id1", "id2", "id3"]
}
步骤 3:生成单个任务(可选)

调用 generate_quest_task 生成单独任务定义:

{
  "title": "收集钻石",
  "description": "获得 5 个钻石",
  "icon": "minecraft:diamond",
  "task_type": "item",
  "target_item": "minecraft:diamond",
  "target_count": 5,
  "x": 0,
  "y": 0
}
