HydraDNS is a self-hosted, network-wide DNS filtering tool built in Go, with a gRPC control plane, web dashboard, DNS-over-HTTPS bypass blocking, and a built-in MCP server so an AI agent can manage the DNS firewall directly. It's positioned as a Pi-hole alternative for self-hosters who want network-wide ad and tracker blocking with AI-agent-manageable controls.
