AI agents call get_pihole_stats to retrieve information from Homelab without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves statistical information from Pi-hole DNS servers. It performs no modifications to DNS configuration, does not execute commands, and does not delete or move data. The operation is purely informational—reading existing metrics.
From the tool's definition Tool name 'get_pihole_stats' and description 'Get DNS statistics from all Pi-hole instances' indicate retrieval of monitoring/diagnostic data without modification or execution of commands.

Register the Homelab MCP server in PolicyLayer and add a rule for get_pihole_stats: 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 Homelab. Nothing to install.
get_pihole_stats 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_pihole_stats 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_pihole_stats. 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.
