GA4の汎用レポートを実行します。任意のディメンションとメトリクスを指定して柔軟にデータを取得できます。
AI agents call run_report to retrieve information from GA4 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool runs reports and retrieves analytics data from Google Analytics 4. Despite the word 'run', it is read-only data retrieval (query/fetch) with no side effects on external systems. The description explicitly states it 'retrieves data' (データを取得). Severity is low as misuse only exposes analytics data.
From the tool's definition "GA4の汎用レポートを実行します。任意のディメンションとメトリクスを指定して柔軟にデータを取得できます" — translates to 'Runs a general-purpose GA4 report. Flexibly retrieves data by specifying any dimensions and metrics.'

GA4の汎用レポートを実行します。任意のディメンションとメトリクスを指定して柔軟にデータを取得できます。. It is categorised as a Read tool in the GA4 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the GA4 MCP Server MCP server in PolicyLayer and add a rule for run_report: 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 GA4 MCP Server. Nothing to install.
run_report 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 run_report 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 run_report. 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.
run_report is provided by the GA4 MCP Server MCP server (shin-sibainu/ga4-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
