Check datasource health. Filter by type or UIDs; omit both to check all.
AI agents call check_datasources_health to retrieve information from Mcp Grafana Npx without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
type | string | — | Plugin type filter; omit to check all |
uids | array | — | UIDs to check |
offset | integer | — | Number to skip for pagination |
Parameters from the server's own tool schema.
This tool queries the health status of datasources without modifying, deleting, or executing any operations. It retrieves information based on optional filters (type or UIDs) but has no side effects. This is a typical Read operation with low blast radius if misused by an AI agent—at worst, it exposes metadata about datasource availability.
From the tool's definition Tool name 'check_datasources_health' and description 'Check datasource health' indicate a query/status-checking operation.
