Returns all clusters
AI agents call ambari_clusters_getclusters to retrieve information from Ambari 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 query operation that retrieves cluster information from the Ambari server without modifying, deleting, executing, or creating any resources. It is a straightforward data retrieval with minimal blast radius if misused by an AI agent—worst case would be information disclosure of cluster metadata.
From the tool's definition Tool name 'ambari_clusters_getclusters' and description 'Returns all clusters' indicate a read-only retrieval operation with no side effects.
