At a Glance & Executive Verdict
Openaq
Developer Tools · Local stdio
Quality: 44/100 (Fair) | Auth: No auth required
Science
Developer Tools · Local stdio
Quality: 48/100 (Fair) | Auth: No auth required
Verdict Summary: Choose Openaq if you need specialized Developer Tools tools running via a local process. Choose Science if your workspace requires Developer Tools integration with local subprocess execution. Both servers can be configured concurrently in your client's
mcpServers manifest.Which MCP Server Should You Choose?

Tools & Capabilities Breakdown
Openaq Tools (4)
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…
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…
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 repo…
