Get all air quality monitors within a latitude/longitude bounding box. Useful for querying monitors in a geographic region that may span multiple states or counties. Parameters: - param: 5-digit AQS parameter code for the pollutant. Common codes: - 44201: Ozone (O3) - 88101: PM2.5 (Fine Particula...
AI agents call aqs_monitors_by_box to retrieve information from EPA Air Quality System (AQS) MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves air quality monitoring station data based on geographic and temporal filters. It has no side effects, does not modify data, does not execute commands, and does not involve financial transactions. It is a straightforward data retrieval operation typical of a public environmental database API.
From the tool's definition Tool name indicates 'Get' operation; description states 'querying monitors in a geographic region'; parameters are all read-only filters (pollutant code, date range, latitude/longitude bounds) with no modification, deletion, or execution capability.

Get all air quality monitors within a latitude/longitude bounding box. Useful for querying monitors in a geographic region that may span multiple states or counties. Parameters: - param: 5-digit AQS parameter code for the pollutant. Common codes: - 44201: Ozone (O3) - 88101: PM2.5 (Fine Particulate Matter, Local Conditions) - 81102: PM10 (Particulate Matter) - 42401: Sulfur Dioxide (SO2) - 42101: Carbon Monoxide (CO) - 42602: Nitrogen Dioxide (NO2) - bdate/edate: Begin and end dates in YYYYMMDD format (must be same calendar year) - minlat: Minimum latitude of bounding box (decimal degrees, e.g., 33.0) - maxlat: Maximum latitude of bounding box (decimal degrees, e.g., 35.0) - minlon: Minimum longitude of bounding box (decimal degrees, e.g., -118.5) - maxlon: Maximum longitude of bounding box (decimal degrees, e.g., -117.0) Example bounding box for Los Angeles area: minlat=33.5, maxlat=34.5, minlon=-118.8, maxlon=-117.5 Note: Email and API key can be provided or will use AQS_EMAIL/AQS_API_KEY environment variables. It is categorised as a Read tool in the EPA Air Quality System (AQS) MCP Server MCP Server, which means it retrieves data without modifying state.
Register the EPA Air Quality System (AQS) MCP Server MCP server in PolicyLayer and add a rule for aqs_monitors_by_box: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches EPA Air Quality System (AQS) MCP Server. Nothing to install.
aqs_monitors_by_box is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the aqs_monitors_by_box rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for aqs_monitors_by_box. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
aqs_monitors_by_box is provided by the EPA Air Quality System (AQS) MCP Server MCP server (tyson-swetnam/aqs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
