Get top queried domains.
AI agents call get_top_domains to retrieve information from Mcp Pihole without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and reports statistics about the most frequently queried domains from Pi-hole's logs. It is a read-only operation that has no side effects—it does not create, modify, delete, or execute any actions. It falls clearly into the Read category.
From the tool's definition Tool name 'get_top_domains' and description 'Get top queried domains' indicate a retrieval operation that queries diagnostic data without modifying any state.
Attacks that exploit this kind of access
Get top queried domains. It is categorised as a Read tool in the Mcp Pihole MCP Server, which means it retrieves data without modifying state.
Register the Mcp Pihole MCP server in PolicyLayer and add a rule for get_top_domains: 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 Mcp Pihole. Nothing to install.
get_top_domains 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 get_top_domains 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 get_top_domains. 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.
get_top_domains is provided by the Mcp Pihole MCP server (obrien-matthew/mcp-pihole). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
