Pi-hole MCP Server: Give AI Agents Access to Your DNS Queries, Block Lists, and Network Activity

Why Give AI Access to Pi-hole?

Pi-hole is the network-wide ad blocker that acts as a DNS sinkhole. It blocks ads, trackers, and malicious domains for every device on your network without requiring client-side software. Over 50 million installations run Pi-hole worldwide.

But when you're coding in Claude or Cursor, your AI assistant can't see your Pi-hole dashboard. It can't tell you which domains are being blocked, whether a DNS query is failing, or what's generating the most traffic on your network. You end up switching to the Pi-hole admin panel constantly.

With DataFaucet, you browse your Pi-hole admin interface once and it captures the API calls as MCP tools. Now your AI coding assistant can query DNS stats, read block lists, and check network activity directly.

What AI Agents Can Do With Pi-hole Access

Once DataFaucet creates an MCP server from your Pi-hole session, AI agents can:

• View query statistics including total queries, blocked percentage, and queries over time
• Check top blocked domains to see what's being filtered most
• List top clients by query volume to identify chatty devices
• Read recent queries with status (blocked, forwarded, cached)
• Inspect block lists and their domain counts
• Check upstream DNS status to verify resolvers are responding
• View gravity database stats including total domains on block lists

Setting Up Pi-hole as an MCP Server with DataFaucet

1. Open your Pi-hole admin dashboard and navigate through the dashboard, query log, and settings pages
2. DataFaucet captures the API calls your browser makes to Pi-hole's admin API
3. Click "Create MCP Server" and DataFaucet generates structured tools from those endpoints
4. Add the MCP server URL to your AI client (Claude, Cursor, Windsurf)
5. Your AI can now query Pi-hole data in real-time

The entire process takes about two minutes. Works with Pi-hole v5 and v6.

Example Queries Your AI Can Answer

After connecting, try asking your AI:

• "What percentage of DNS queries are being blocked today?"
• "Which domain is getting blocked the most?"
• "What device on my network is making the most DNS queries?"
• "Is pi-hole blocking any queries to api.example.com?"
• "How many domains are on my block lists total?"
• "Are upstream DNS resolvers healthy?"

Your AI can answer these instantly because it has real-time access to your Pi-hole API through MCP tools.

DataFaucet vs Pi-hole's API

Self-Hosted Pi-hole Works Great

Since DataFaucet captures API calls from your browser, it works with any Pi-hole instance on your network. Your AI assistant gets the same data you see in the admin panel, whether Pi-hole runs on a Raspberry Pi, a Docker container, or a VM.

Use Cases

• Network debugging: Ask "is Pi-hole blocking this domain?" when an API call fails
• Security monitoring: AI reads query logs to flag suspicious domains
• Ad-block verification: Confirm new block lists are working without checking the dashboard
• Device auditing: Identify which devices are making unusual DNS requests
• DNS health checks: AI verifies upstream resolvers are responding normally

Get Started

DataFaucet turns your Pi-hole admin panel into structured MCP tools in under two minutes. No SSH access, no API token configuration, no custom scripts.

Create your Pi-hole MCP server and give your AI coding assistant full visibility into your network's DNS activity.
