Openaq MCP Server
cyanheads · MCP server
Air-quality measurements from OpenAQ, drawn from government reference monitors and research-grade sensors worldwide. Your agent can find monitoring stations near a point, inside a bounding box or by country, read the latest value of every sensor at a station with its pollutant and unit, and pull the historical series for one pollutant, either raw or rolled up by hour or day. It can also list the pollutants and countries covered. An OpenAQ API key is needed.
Written by ooruby from the README of @cyanheads/openaq-mcp-server 0.4.1.

Why it's useful
Your agent can answer air-quality questions from sensor measurements instead of general statements about a place.
What you could do with it
- Find monitoring stations within a set radius of a coordinate and see which pollutants each measures.
- Read the latest sensor values at a station, labelled with pollutant and unit.
- Pull a daily rollup of one pollutant at a station over a date range.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
What this does not cover
- Everything. Treat it as you would software from anywhere else.
Receipt history: every signed receipt for every version of this listing, and what changed between them.
In its maker's words
Find air-quality monitoring stations, read latest sensor values, and pull historical pollutant series via MCP. STDIO or Streamable HTTP.

How far this has been checked
Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 0.4.1, the file with digest sha512-3riUYXK8jRnNI1Jjd+w/W94I/xXnhNSTYZsa8LRiZlCdbiJjrqtLcYXaRbzQP8/QltMPsJzBbyAJKZq9GgyEug==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- No auth declared. Its hosted endpoint, as the official MCP registry lists it, does not say it asks for a key. That is what the listing declares, not a finding that it has no protection.
Adding it
Paste this into your client's MCP configuration.

No build provenance published. The repository above is the one the publisher declared, and nothing links it to the package you would install. That is not a mark against this listing, since most packages are published this way, but it is a check nobody can run.
The badge, if this is your listing
It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
