AI agents call grafana_list_dashboards to retrieve information from Homelab without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a straightforward read operation that queries Grafana's dashboard inventory and returns metadata. It has no capability to modify, delete, execute, or trigger external operations. The blast radius of misuse is minimal—an AI agent could only enumerate dashboards, which is informational retrieval with no destructive potential.
