Overview

What is PiHole MCP Server?

PiHole MCP Server is a Java-based MCP (Model Context Protocol) server that enables AI applications to manage a Pi-hole instance through standard commands. It is designed for users who want to control Pi-hole DNS blocking, domain lists, and retrieve statistics from an AI assistant.

How to use PiHole MCP Server?

Ensure Java 21 is installed, download the JAR from the releases page, and configure your AI client with the server command (java -jar /path/to/pihole-mcp.jar) and environment variables (PIHOLE_HOST, PIHOLE_APP_PASSWORD, and optionally PIHOLE_PORT). Then, restart the client to make the tools available.
