AI agents call get_productivity_metrics to retrieve information from Rize Io 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 or queries productivity metrics data from Rize.io without modifying, deleting, or triggering external side effects. It aligns with the server's stated purpose of enabling 'natural language queries about productivity metrics.' The pattern of 'get_*' sibling tools confirms this is a read-only operation.

{
"version": "1",
"default": "deny",
"tools": {
"get_productivity_metrics": {}
}
