## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-17.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs hatchling.build at install time, a recognised build step with no custom scripting around it.
  - 2 of 37 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to mouseart2025/china-context-mcp).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 20 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 72/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 843 tokens (~168/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 70/100
  - Stability observed for 21 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (5)

### `random_poem` (~65 tokens)

Random Poem

随机返回一句中国古典诗词，含作者、出处与分类。

适用：中文创作灵感、文化问答、语文/国学类 AI 陪练。
数据来自 jinrishici.com（公开、零凭证）。

Output parameters:

- `result` (string)

### `holiday_info` (~258 tokens)

Holiday Info

查询中国某日期的节假日 / 调休 / 是否工作日信息。

参数 date：YYYY-MM-DD，例如 "2026-10-01"。
返回：节假日名称、是否法定假日、是否调休补班工作日、工资倍率。
数据来自 timor.tech（公开、零凭证）+《全国年节及纪念日放假办法》法规常量层（离线）。

★ 三态语义（本工具的核心契约，不得退化）：
  \- 该年份有权威数据 ⇒ 正常给出法定假日 / 工作日 / 倍率。
  \- 该年份无数据，但日期是《放假办法》规定的**公历固定法定节假日**
    （元旦 1/1、劳动节 5/1-5/2、国庆 10/1-10/3）⇒ 法定假日**是**，并注明放假起止与调休待公布。
  \- 其余无数据情况 ⇒ 明确说「暂无权威数据、无法判断」，**绝不说「否」**。

Input parameters:

- `date` (string, required)

Output parameters:

- `result` (string)

### `holiday_summary` (~211 tokens)

Holiday Summary

返回中国某年的节假日与调休摘要——聚合推导，不是单日查询。

与 holiday_info 的区别：本工具对 timor 全年扁平数据做聚合，给出
holiday_info 拿不到、而 AI 自身容易算错的结论——连续假期区间与天数、
法定 3 倍工资天数与**具体是哪几天**、全部调休补班日、全年总休假天数。
每条区间的逐日明细按工资倍率分组输出，例如
\`3倍 4 天：02-16、02-17 初一、02-18 初二、02-19 初三`。

参数 year：4 位年份，省略则用当前年。
适用：年度休假规划、考勤与排班、HR 与薪酬核算。
数据来自 timor.tech（公开、零凭证）。

Input parameters:

- `year`

Output parameters:

- `result` (string)

### `history_today` (~117 tokens)

History Today

返回「历史上的今天」：某月某日发生的历史事件列表（标题 + 年份 + 简述）。

参数 date：可选，格式 "MM-DD"（如 "09-25"）或 "YYYY-MM-DD"（如 "2026-09-25"）。
          省略则使用今天。
适用：历史问答、内容创作、文化类 AI 陪练。
数据来自 60s-api.viki.moe（公开、零凭证）。

Input parameters:

- `date`

Output parameters:

- `result` (string)

### `idcard_check` (~192 tokens)

Idcard Check

校验中国居民身份证号（GB 11643），并解析国标公开字段。

★ 纯本地算法，不联网、零凭证：按 ISO 7064 MOD 11-2 加权算法验证末位校验码。
  这类 17 位加权求和 + 模 11 查表，**AI 自行计算极易出错**（因子表或索引错位）。
  因此本工具的价值不在"包 API"（它无 API 可包），而在**替 AI 算对**。

参数 id_number：18 位身份证号，末位 X/x 大小写均可。
隐私：仅解析国标公开字段（出生日期/性别/省级），不触姓名与住址；回显做中间掩码。

Input parameters:

- `id_number` (string, required)

Output parameters:

- `result` (string)
