Mcp Openaq — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Mcp Openaq (Agent Skill) and scored it 100/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 0 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

The primary manifest — the file an agent reads to learn what this artifact does.
OpenAQ MCP — global air-quality measurements via the OpenAQ v3 API.
Part of Pipeworx — an MCP gateway connecting AI agents to 1856+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.
| Tool | Description |
|---|---|
air_quality_near | Get the latest air-quality readings (PM2.5, PM10, O3, NO2, SO2, CO, etc.) at the monitoring station NEAREST to a latitude/longitude. PREFER for "air quality near me", "what is the air quality at <coordinates>", "is the air bad in <place> right now". Returns the nearest station with its most recent pollutant values, plus other nearby stations. |
find_stations | Find OpenAQ air-quality monitoring stations by location: a city or place name, coordinates+radius (nearest first), a country (ISO 3166-1 alpha-2 code), or a bounding box. Returns station id, name, country, coordinates, and the pollutants each measures (with sensor ids), plus resolved_place echoing the coordinates a city name resolved to. This is the first step for a historical series: find the station here, then pass its sensor_id to get_measurements. At least one location argument is required — the tool will not return an unfiltered global list. |
get_latest | Get the latest reading for every pollutant at a specific OpenAQ station (by location id from find_stations). Returns each parameter (PM2.5, O3, NO2, etc.) with its value, units, and measurement time. |
get_measurements | Get the most recent time series (hourly or daily aggregates) for a single OpenAQ sensor (sensor id from find_stations), newest first. Use for pollutant trends over time at one station/parameter. Returns the sensor's LAST limit readings — note that many OpenAQ sensors are archived and stopped reporting years ago, so "most recent" can legitimately be several years old: always read the returned timestamps rather than assuming the data is current. Use find_stations or get_latest to pick a sensor that is still reporting. |
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

"openaq": {
"url": "https://gateway.pipeworx.io/openaq/mcp"
}
}
}tools/list at https://gateway.pipeworx.io/openaq/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.
This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.
Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}Both URLs reach the same gateway and the same 1856+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.
curl -X POST https://gateway.pipeworx.io/v1/tools/air_quality_near \
-H 'Content-Type: application/json' \
-d '{"latitude":40.785,"longitude":-73.968}'No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/air_quality_near. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.
@pipeworx/mcp-openaq is a local stdio bridge to the Pipeworx gateway: your MCP client starts it with npx, and it forwards every call to the same https://gateway.pipeworx.io/openaq/mcp endpoint shown above. It needs network access; there is no offline mode.
{
"mcpServers": {
"openaq": {
"command": "npx",
"args": ["-y", "@pipeworx/mcp-openaq"]
}
}
}Without a key it calls anonymously, capped at 50 calls a day. A free account raises that to 200 a day: get a key at https://pipeworx.io/signup and add "env": { "PIPEWORX_API_KEY": "<your key>" } to the server entry. The key is sent as a Bearer token, the same way a hosted connection sends it, so calls are metered and billed exactly as they are there.
It lists only this pack's tools by default. Set PIPEWORX_META_TOOLS=1 to also list ask_pipeworx and the other gateway-wide tools.
Behind an HTTPS proxy: Node's built-in fetch does not read HTTPS_PROXY by default. Newer Node releases honour it when NODE_USE_ENV_PROXY=1 is set; check your Node version's documentation.
Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:
ask_pipeworx({ question: "your question about Openaq data" })The gateway picks the right tool and fills the arguments automatically.
