At a Glance & Executive Verdict
Openaq
Environment & Nature · Local stdio
Quality: 49/100 (Fair) | Auth: No auth required
Usgs Water
Environment & Nature · Local stdio
Quality: 48/100 (Fair) | Auth: No auth required
Verdict Summary: Choose Openaq if you need specialized Environment & Nature tools running via a local process. Choose Usgs Water if your workspace requires Environment & Nature integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Openaq when:
You need dedicated capabilities in the Environment & Nature domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
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…
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Openaq is categorized under Environment & Nature and uses a local stdio subprocess. In contrast, Usgs Water belongs to Environment & Nature using local stdio subprocess. Select Openaq when you need capabilities focused on environment & nature and Usgs Water when you require tools for environment & nature.
Latest instantaneous (real-time) readings for one or more USGS gauge sites. Returns the most recent value per site × parameter — e.g. current streamflow and gage height for a river. Common parameter codes: 00060 = discharge/streamflow (ft³/s), 00065 = gage height (ft), 00010 = water temperature (°C…
daily_values
Daily-values time series for a single USGS site + parameter over a date range. Returns one statistic per day (default mean). Useful for trends, hydrographs, and historical comparison. Common statCd: 00003 = mean, 00001 = max, 00002 = min. Common parameter codes: 00060 = discharge (ft³/s), 00065 = g…
find_sites
Discover active USGS gauge sites in a US state that are currently reporting a given parameter (real-time). Returns sites with their latest reading; useful for finding which gauges are live in a region. Can match many sites, so results are capped. Keyless.
