Openaq vs Weather for Grown Ups
A side-by-side look at the Openaq and Weather for Grown Ups MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Openaq for environment & nature work as a local process; choose Weather for Grown Ups for environment & nature as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Openaq when
- You need dedicated capabilities in the Environment & Nature domain.
- You prefer a local stdio subprocess transport.
- You want tools like
air_quality_near, find_stations, get_latest.
Choose Weather for Grown Ups when
- You need dedicated capabilities in the Environment & Nature domain.

Tools & capabilities
Openaq tools 4
air_quality_nearGet 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_stationsFind 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_latestGet 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_measurementsGet 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.

Openaq has no declared pricing — check the project's own site. Weather for Grown Ups has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add openaq and weather-for-grown-ups as separate keys in the same mcpServers object, and your assistant will call tools from either one.
