Get current or historical combined Ozone and PM2.5 contour maps in KML by geographic bounding box.
AI agents call get-contour-maps-by-bounding-box-combined-ozone-pm25 to retrieve information from AirNow MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation that queries and returns air quality contour map data in KML format. There are no side effects, data modifications, destructive operations, code execution, or financial implications. The blast radius of misuse is minimal—an attacker could only obtain air quality information for specific geographic areas, which is already public data from the AirNow API.
From the tool's definition Tool retrieves 'current or historical combined Ozone and PM2.5 contour maps in KML' by geographic bounding box. The verb 'Get' and 'retrieves' indicate data query operations with no modification, deletion, or execution of external actions.
Attacks that exploit this kind of access
Get current or historical combined Ozone and PM2.5 contour maps in KML by geographic bounding box. It is categorised as a Read tool in the AirNow MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AirNow MCP Server MCP server in PolicyLayer and add a rule for get-contour-maps-by-bounding-box-combined-ozone-pm25: 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 AirNow MCP Server. Nothing to install.
get-contour-maps-by-bounding-box-combined-ozone-pm25 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 get-contour-maps-by-bounding-box-combined-ozone-pm25 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 get-contour-maps-by-bounding-box-combined-ozone-pm25. 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.
