list_zones_tool
AI agents call list_zones_tool to retrieve information from MCP Cloudflare without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves zone information without modifying, deleting, or executing any actions. While the description is empty, the name unambiguously suggests a list operation, which is a read-only retrieval. The sibling tools include destructive operations (delete_*), but this tool is clearly in the Read category.
