## 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-waqi).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 6 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 76/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 496 tokens (~124/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **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 4 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 supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-10-29 (score 81)

First indexed and scored.

## MCP tools (4)

### `get_aqi_by_city` (~258 tokens)

Latest AQI for a city from the World Air Quality Index Project station network. Accepts "city" or "city, country" (e.g. "Rome, Italy"). The matched station is checked against the requested place: a station that is not plausibly in it (the upstream resolves "Venice" to Dayton, Ohio) is never served; the call errors naming what it matched and listing candidates, and the response carries a place block stating requested vs matched. Every reading carries measured_at, station identity, data_age_hours and freshness. A reading older than 24h is never returned as current: a reporting station within 100 km is used (station_selection=fallback_fresher_station; skipped_stale_station says what was passed over) or the call errors naming the station and its age. Returns AQI value, dominant pollutant, individual pollutant readings (PM2.5, PM10, O3, NO2, SO2, CO), temperature/humidity/pressure, and station info.

Input parameters:

- `city` (string, required): City name, optionally qualified by country or region after a comma (e.g., "beijing", "los-angeles", "Rome, Italy", "Paris, Texas")

### `get_aqi_by_location` (~75 tokens)

Latest AQI for the WAQI station nearest a lat/lon. Carries measured_at, data_age_hours and freshness; a station silent for over 24h is replaced by a reporting one within 100 km or the call errors.

Input parameters:

- `latitude` (number, required): Latitude
- `longitude` (number, required): Longitude

### `get_aqi_by_station` (~70 tokens)

Latest AQI for a specific WAQI station by UID (numeric). Returned as asked even if the station has gone quiet, so check freshness and data_age_hours (stale = over 24h).

Input parameters:

- `station_id` (number, required): WAQI station UID (returned by search_stations)

### `search_stations` (~41 tokens)

Search stations by keyword (city/region name). Returns station UID, name, current AQI, and location.

Input parameters:

- `keyword` (string, required): Search keyword

## Common questions

### What is the Waqi MCP server?

Waqi is an MCP server listed in the public MCP registry as io.github.pipeworx-io/waqi. WAQI MCP, World Air Quality Index (free key). This page covers its npm package (@pipeworx/mcp-waqi).

### Is the Waqi MCP server safe to use?

Waqi scores 81 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Waqi MCP server expose?

Waqi exposes 4 tools: get_aqi_by_city, get_aqi_by_location, get_aqi_by_station, search_stations. Their descriptions and schemas cost roughly 444 tokens of context every time the server is loaded.

### Is the Waqi MCP server still maintained?

Waqi is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Waqi MCP server under?

Waqi declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Waqi MCP server?

VerifyMCP ran 15 checks on Waqi, covering Malware scan, Known CVEs, Install scripts, Dependency health and 11 more. One item could not be completed, a gap on our side rather than a finding about Waqi: Stability. One category scores 0 for that reason, because we only credit what we can confirm. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
