Lets an assistant look up US EPA air quality, AQI forecasts, annual air statistics, TRI facilities and Superfund sites.
What you can do
Provides five read-only tools over US EPA data. It returns current AQI values, pollutant levels and health categories for a ZIP code or latitude/longitude, plus short-range AQI forecasts for a ZIP code. It also returns annual air quality statistics for a state, Toxics Release Inventory facilities by state and optional city, and active Superfund sites on the National Priorities List by state.
When to use it
Useful when someone asks about air quality or health risk at a US location, wants a short forecast, or needs environmental context such as nearby toxic-release facilities or Superfund cleanup sites in a state.
Requirements
A remote streamable HTTP endpoint; no local runtime, package, API key or environment variables are declared. Queries need US locations: ZIP codes, latitude/longitude, or two-letter state abbreviations.
Before you install
Results are limited to US EPA data and nearest monitoring stations, so they may not reflect conditions at the exact address. All tools appear read-only; no credentials, payments or write actions are declared.
Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/com.olyport%2Fepa/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.
Get the current Air Quality Index (AQI) for a location.
Provide either a zip_code OR latitude/longitude coordinates.
Returns AQI values, pollutant levels, and health category for
each measured pollutant at the nearest monitoring station.
Args:
zip_code: US ZIP code (e.g. '20001').
latitude: Latitude of the location (e.g. 38.9).
longitude: Longitude of the location (e.g. -77.0).

Get the air quality forecast for a ZIP code.
Returns forecast AQI values and health categories for upcoming days,
typically covering today and the next 1-2 days.
Args:
zip_code: US ZIP code (e.g. '20001').
Parameterszip_coderequired
get_annual_air_quality
Get annual air quality summary data for a US state.
Returns annual statistics from the EPA Air Quality System (AQS),
including mean concentrations, max values, and exceedance counts
