List all Cloudflare zones (domains) in your account. e.g., returns all domains like example.com and myapp.io with their zone IDs, status, and plan. Use this first to get zone IDs needed by other tools.
AI agents call list_zones to retrieve information from Cloudflare Control without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries account metadata (domain/zone information) without any side effects. It is a read-only operation that merely enumerates existing zones. While information disclosure about account domains has some sensitivity, the impact is limited compared to tools that modify DNS records, purge caches, or execute Workers. Classified as Read with low severity.
From the tool's definition Tool name is 'list_zones' and description states it 'List all Cloudflare zones (domains) in your account' and 'returns all domains like example.com and myapp.io with their zone IDs, status, and plan.' This is purely a retrieval operation with no modification,…
Attacks that exploit this kind of access
List all Cloudflare zones (domains) in your account. e.g., returns all domains like example.com and myapp.io with their zone IDs, status, and plan. Use this first to get zone IDs needed by other tools. It is categorised as a Read tool in the Cloudflare Control MCP Server, which means it retrieves data without modifying state.
Register the Cloudflare Control MCP server in PolicyLayer and add a rule for list_zones: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Cloudflare Control. Nothing to install.
list_zones is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_zones rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_zones. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
list_zones is provided by the Cloudflare Control MCP server (josephtandle/cloudflare-mcp-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
