AI agents call aqs_annual_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 retrieves and aggregates historical air quality statistics from EPA monitoring sites. It performs data retrieval with no side effects—no data is created, modified, deleted, or externally executed. The geographic bounding box parameters and data filtering are part of a standard query operation.
From the tool's definition Tool description uses "Get" and specifies retrieval of "annual summary data" including "statistics such as arithmetic mean, standard deviation, maximum values, percentiles". No mention of creation, modification, deletion, or execution of external operations.
Attacks that exploit this kind of access
Get annual summary data for all monitoring sites within a geographic bounding box defined by latitude/longitude coordinates. Annual summaries include yearly statistics such as arithmetic mean, standard deviation, maximum values, percentiles (10th through 99th), observation counts, data completeness metrics, and exceedance counts for primary and secondary NAAQS standards. 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_annual_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_annual_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_annual_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_annual_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_annual_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.
