Aggregate GA4 API response rows by one dimension, summing all numeric metrics and optionally returning only the top N results. e.g., input: rows with country+device dimensions, aggregate_by=
AI agents call aggregate_rows to retrieve information from Query Analytics without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs in-memory aggregation and summarization of already-retrieved GA4 analytics data. It does not fetch, modify, delete, or execute anything externally — it processes existing row data by summing metrics and filtering top N results. This is a pure read/transform operation with no side effects.

Attacks that exploit this kind of access
Aggregate GA4 API response rows by one dimension, summing all numeric metrics and optionally returning only the top N results. e.g., input: rows with country+device dimensions, aggregate_by=. It is categorised as a Read tool in the Query Analytics MCP Server, which means it retrieves data without modifying state.
Register the Query Analytics MCP server in PolicyLayer and add a rule for aggregate_rows: 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 Query Analytics. Nothing to install.
aggregate_rows 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 aggregate_rows 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 aggregate_rows. 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.
aggregate_rows is provided by the Query Analytics MCP server (josephtandle/google-analytics-mcp-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
