List referrer statistics.
AI agents call get_stats_refs to retrieve information from Goatcounter 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 referrer statistics from Goatcounter analytics, which is a read-only query operation. It does not create, modify, delete, or execute any actions—it only fetches and returns existing analytics data. There is no financial impact, no code execution, and no data modification capability. The low severity reflects minimal risk even if an AI agent calls it with valid parameters.
From the tool's definition Tool name 'get_stats_refs' and description 'List referrer statistics' indicate a query operation that retrieves analytics data.
