WHAT IT DOES

What list_alert_rules does on Grafana MCP Server

AI agents call list_alert_rules to retrieve information from Grafana MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_alert_rules is rated Low

This tool queries and retrieves metadata about existing alert rules from Grafana. It performs a simple enumeration/listing operation with read-only semantics. There is no creation, modification, deletion, or execution of external actions. The blast radius if misused by an AI agent is minimal—an attacker gains visibility into alert configuration but cannot alter monitoring behavior or trigger incidents.

From the tool's definition Tool name 'list_alert_rules' and description 'Lists Grafana alert rules, returning a summary including UID, title, current state, and labels' indicates data retrieval with no modification or side effects.
