Returns a collection of all hosts
AI agents call ambari_hosts_gethosts 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 Ambari cluster without modifying, deleting, or executing any operations. It is a simple data retrieval function that poses minimal risk if misused by an AI agent, as the worst outcome would be information disclosure about cluster hosts.
From the tool's definition Tool name contains 'get' and description states 'Returns a collection of all hosts' — a query operation with no side effects.
