Get daily summary air quality data for all monitoring sites within a geographic bounding box. Daily summaries include arithmetic mean, maximum values, observation counts, and AQI values for each day. Specify the bounding box using minimum and maximum latitude/longitude coordinates.
AI agents call aqs_daily_summary_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 only queries and retrieves existing air quality monitoring data from EPA's system. It has no side effects, does not modify any data, does not execute code or commands, and does not perform destructive operations. The 'Get' verb and read-only data retrieval pattern are consistent with the Read category.
From the tool's definition Tool retrieves daily summary air quality data using geographic coordinates—queries data without modification, creation, deletion, or execution of external operations.
Attacks that exploit this kind of access
Get daily summary air quality data for all monitoring sites within a geographic bounding box. Daily summaries include arithmetic mean, maximum values, observation counts, and AQI values for each day. Specify the bounding box using minimum and maximum latitude/longitude coordinates. 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_daily_summary_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_daily_summary_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_daily_summary_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_daily_summary_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_daily_summary_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.
