Get raw sample data for all monitoring sites within a geographic bounding box. 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_sample_data_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_sample_data_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_sample_data_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.
