List all alert rule groups
AI agents call list_alert_rule_groups to retrieve information from Grafana MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query to enumerate existing alert rule groups in Grafana. It retrieves information without creating, modifying, deleting, or executing any operations. The action is non-destructive and has no side effects. While listing alert rules could expose configuration details, the severity remains low as it is purely informational with minimal blast radius if misused by an agent.
From the tool's definition Tool name 'list_alert_rule_groups' and description 'List all alert rule groups' indicate a retrieval operation with no modification of data.
