Get a metric breakdown for a website and time range. Use expanded=true for detailed metrics or expanded=false for x/y breakdown rows.
AI agents call umami_get_breakdown to retrieve information from Umami 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 analytics metric data without any side effects. It performs a query/get operation on existing analytics data for visualization purposes. The read-only nature of the server and the query-style operation (GET breakdown metrics with optional expansion flags) confirm this is a Read category tool with low severity, as it cannot modify data, execute arbitrary code, or cause financial transactions.
From the tool's definition Tool description states 'Get a metric breakdown' with parameters for expanded views of metrics; server is explicitly described as 'Read-only MCP server for Umami analytics' that 'talks to the Umami REST API directly over HTTP'; no create, modify, delete, or…

Get a metric breakdown for a website and time range. Use expanded=true for detailed metrics or expanded=false for x/y breakdown rows. It is categorised as a Read tool in the Umami MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Umami MCP Server MCP server in PolicyLayer and add a rule for umami_get_breakdown: 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 Umami MCP Server. Nothing to install.
umami_get_breakdown 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 umami_get_breakdown 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 umami_get_breakdown. 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.
umami_get_breakdown is provided by the Umami MCP Server MCP server (mzaxd/umami-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
