get_datasource_health
AI agents call get_datasource_health to retrieve information from Mcp Read Only Grafana without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves health status information about a Grafana datasource. It does not create, modify, delete, or execute operations—it only reads state information. The empty description and server's read-only positioning reinforce this as a Read category tool with low risk if misused by an AI agent.
From the tool's definition Tool name 'get_datasource_health' indicates a retrieval operation. Server description explicitly states 'read-only access by default'. The 'get_' prefix is a strong indicator of a query/fetch operation with no side effects.
