tool_list_sites
AI agents call tool_list_sites to retrieve information from Frappe MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name and server context indicate this retrieves or enumerates sites without altering data. Despite the empty description reducing confidence slightly, the clear semantics of 'list' operation and server context confirming site listing as a supported read-only operation justify classification as Read with low severity.
From the tool's definition Tool name 'tool_list_sites' indicates a listing/query operation with no modification capability. Server description mentions 'listing sites' as a non-destructive operation.
