**2 tools: 2 change things.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 0 | deny |
| Can't be undone | irreversible | 0 | ask |
| Changes things | write | 2 | ask |
| Only reads | read | 0 | allow |

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `da_liu_ren_calculate`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
大六壬（Da Liu Ren）是中国古代三式之一，以人事预测见长，擅长判断日常生活中的人事问题。

## 核心概念
- **四课**：由日干、日支加上天地盘推演出的四个课位，反映事物的基本结构
- **三传**：初传（发用）、中传、末传，反映事态发展的过程（起始→发展→结局）
- **十二天将**：贵人、腾蛇、朱雀、六合、勾陈、青龙、天空、白虎、太常、玄武、太阴、天后
- **月将**：太阳所在的黄道位置，加于时支之上布天盘
- **课体**：根据四课的推导方式命名（如元首课、重审课、涉害课、遥克课等）
- **六亲**：父母、兄弟、子孙、妻财、官鬼——反映事物之间的生克关系
- **神煞**：驿马、桃花、华盖、天德、月德、旬空等辅助判断

## 解读要点
1. **看课体**：课体决定了取传方法，不同课体暗示事物的性质
   - 元首课：事情自上而下，领导之象
   - 重审课：需要反复斟酌
   - 涉害课：牵涉面广，事多阻碍
   - 遥克课：远方来事，需等待
2. **看三传**：
   - 初传（发用）：事情的起因和开端
   - 中传：事情的发展过程
   - 末传：事情的最终结局
   - 三传递生为吉，递克为凶
3. **看天将**：
   - 青龙主吉庆、贵人主贵助
   - 白虎主凶险、玄武主暗昧
4. **看日干旺衰**：日干代表求测人，旺则有力，衰则无力
5. **看空亡**：旬空之支所临之神/将力量减弱

## 常见用途
- 求财：看妻财爻、青龙、生门
- 求官：看官鬼爻、朱雀、贵人
- 婚姻：看天后、六合、妻财爻
- 疾病：看天医、白虎、病符
- 出行：看驿马、太冲、天马
```

### `qimen_dunjia_calculate`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
奇门遁甲（Qimen Dunjia）是中国古代三式之一，被称为"帝王之学"。通过天时、地利、人和三维度分析时空能量场。

## 核心概念
- **九宫**：坎(1)、坤(2)、震(3)、巽(4)、中(5)、乾(6)、兑(7)、艮(8)、离(9)，对应八方和五行
- **天盘/地盘**：天干在九宫中的分布，天盘为动态，地盘为静态
- **九星**：天蓬、天芮、天冲、天辅、天禽、天心、天柱、天任、天英
- **八门**：休门、生门、伤门、杜门、景门、死门、惊门、开门
- **八神**：值符、腾蛇、太阴、六合、白虎、玄武、九地、九天
- **值符/值使**：当前时刻的主星和主门，是判断吉凶的核心

## 解读要点
1. **看值符值使**：值符星和值使门的状态决定总体吉凶
2. **看用神宫位**：根据用途找到对应宫位（如求财看生门所在宫）
3. **看三奇六仪**：乙丙丁为三奇（吉），戊己庚辛壬癸为六仪
4. **看格局**：天盘与地盘天干组合形成吉格（如龙遁、虎遁）或凶格（如击刑、入墓）
5. **看空亡**：落入空亡的宫位力量减弱

## 常见用途
- 求财：重点看生门、戊
- 事业：重点看开门、值使
- 感情：重点看六合、天后
- 出行：重点看三奇得使、门迫否
```

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

https://profound.fate-craft.com/api/mcp: tools/list returned 2 tools to an anonymous client, including qimen_dunjia_calculate (write), da_liu_ren_calculate (write)
