List all tenants in the ACI fabric
AI agents call list_tenants to retrieve information from ACI 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 to retrieve and display existing tenant information from the ACI infrastructure. It has no side effects, does not modify or delete any configuration, and does not execute commands or trigger external operations. This is a straightforward read-only data retrieval action, posing minimal risk even if misused by an AI agent.
From the tool's definition Tool name is 'list_tenants' and description states 'List all tenants in the ACI fabric' — a retrieval operation with no modification or deletion of data.
