List all available farms.
AI agents call list_all_farms to retrieve information from Farm OS 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 or queries farm data without modifying, deleting, or executing any operations. It is a read-only operation that returns a list of farms, consistent with the 'Read' category for tools that retrieve data without side effects.
From the tool's definition Tool name 'list_all_farms' and description 'List all available farms' indicate a query/retrieval operation with no side effects.
