## 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 2026-11-05.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-china-air-quality).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 5 days ago).
  - Security-disclosure policy not yet verified: we couldn't inspect the source repository.
- **Schema Quality & AI Usability**: 68/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 518 tokens (~172/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (3)

### `china_air_quality` (~173 tokens)

Real-time air quality (空气质量) for a Chinese city — AQI, pollutant levels and concentrations (PM2.5, PM10, O3, NO2, SO2, CO), quality rating, primary pollutant and station count. Accepts an English city name ("Beijing", "Shanghai"), a province name ("Guangdong" resolves to Guangzhou), or the Chinese name ("北京市"). Answers "what is the air quality in Beijing right now", "is Shanghai's air safe today", "PM2.5 in Chengdu". Sourced from China National Environmental Monitoring Centre (中国环境监测总站), refreshed hourly.

Input parameters:

- `city` (string, required): City or province name, English or Chinese, e.g. "Beijing", "beijing", "北京市", "Guangdong".

### `china_air_quality_ranking` (~176 tokens)

Nationwide ranking of Chinese cities by air quality (空气质量排名) — the cleanest or most polluted cities right now, optionally ranked by a specific pollutant instead of overall AQI. Answers "which Chinese cities have the worst air quality today", "cleanest cities in China right now", "top 10 most polluted cities in China by PM2.5". Covers all 338 CNEMC-monitored prefecture-level cities.

Input parameters:

- `direction` (string): "top" = cleanest (lowest AQI) first; "bottom" = most polluted (highest AQI) first. Default "bottom".
- `n` (number): How many cities to return, 1-50 (default 10).
- `pollutant` (string): Rank by this pollutant's index level instead of overall AQI.

### `china_air_quality_stations` (~114 tokens)

Individual monitoring-station readings (监测站点数据) within one Chinese city — every station's AQI, pollutant concentrations and quality rating, with station name and coordinates. Use this for neighborhood-level detail within a city, e.g. "which part of Shanghai has the worst air right now" or "list the air monitoring stations in Beijing". Accepts an English or Chinese city name.

Input parameters:

- `city` (string, required): City name, English or Chinese, e.g. "Shanghai", "上海市".
