Returns information about a single host
AI agents call ambari_hosts_gethost 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 retrieves host information from an Apache Ambari cluster without modifying, deleting, or executing actions. It is a straightforward read operation that returns data only. Low severity because unauthorized host information disclosure has minimal immediate impact in a cluster management context, though it could inform further attacks.
From the tool's definition Tool name 'gethost' and description 'Returns information about a single host' indicate a query/retrieval operation with no side effects.
