MCP AdGuard Home

MCP server for AdGuard Home. Manage DNS filtering, clients, DHCP, rewrites, and more through natural language in Cursor, Claude Code, and Claude Desktop.

Features

• 65 tools across 16 categories covering the complete AdGuard Home API
• Read-only mode via ADGUARD_ACCESS_TIER=read-only for safe monitoring
• Category filtering via ADGUARD_CATEGORIES to expose only the tools you need
• Zero HTTP dependencies -- uses native fetch (Node.js 22+)
• Docker images for linux/amd64 and linux/arm64 on GHCR
• Remote MCP via HTTP transport (MCP_TRANSPORT=http) using the Streamable HTTP protocol
• TypeScript/ESM with full type safety

API Compatibility

Tested with AdGuard Home v0.107.76.

Quick Start

Run the server directly with npx:

ADGUARD_URL="http://your-adguard-ip:3000" \
ADGUARD_USERNAME="your-username" \
ADGUARD_PASSWORD="your-password" \
npx -y @samik081/mcp-adguard-home

The server validates your AdGuard Home connection on startup and fails immediately with a clear error if credentials are missing or invalid.

Docker

Run with Docker (stdio transport, same as npx):

docker run --rm -i \
  -e ADGUARD_URL=http://your-adguard-ip:3000 \
  -e ADGUARD_USERNAME=your-username \
  -e ADGUARD_PASSWORD=your-password \
  ghcr.io/samik081/mcp-adguard-home

To run as a remote MCP server with HTTP transport:

docker run -d -p 3000:3000 \
  -e MCP_TRANSPORT=http \
  -e ADGUARD_URL=http://your-adguard-ip:3000 \
  -e ADGUARD_USERNAME=your-username \
  -e ADGUARD_PASSWORD=your-password \
  ghcr.io/samik081/mcp-adguard-home

The MCP endpoint is available at http://localhost:3000 and a health check at http://localhost:3000/health.

Configuration

Claude Code CLI (recommended):

# Using npx
claude mcp add --transport stdio adguard-home \
  --env ADGUARD_URL=http://your-adguard-ip:3000 \
  --env ADGUARD_USERNAME=your-username \
  --env ADGUARD_PASSWORD=your-password \
  -- npx -y @samik081/mcp-adguard-home

# Using Docker
claude mcp add --transport stdio adguard-home \
  --env ADGUARD_URL=http://your-adguard-ip:3000 \
  --env ADGUARD_USERNAME=your-username \
  --env ADGUARD_PASSWORD=your-password \
  -- docker run --rm -i ghcr.io/samik081/mcp-adguard-home

# Using remote HTTP (connect to a running Docker container or HTTP server)
claude mcp add --transport http adguard-home http://localhost:3000

JSON config (works with Claude Code .mcp.json, Claude Desktop claude_desktop_config.json, Cursor .cursor/mcp.json):

{
  "mcpServers": {
    "adguard-home": {
      "command": "npx",
      "args": ["-y", "@samik081/mcp-adguard-home"],
      "env": {
        "ADGUARD_URL": "http://your-adguard-ip:3000",
        "ADGUARD_USERNAME": "your-username",
        "ADGUARD_PASSWORD": "your-password"
      }
    }
  }
}

Docker (stdio):

{
  "mcpServers": {
    "adguard-home": {
      "command": "docker",
      "args": ["run", "--rm", "-i",
        "-e", "ADGUARD_URL=http://your-adguard-ip:3000",
        "-e", "ADGUARD_USERNAME=your-username",
        "-e", "ADGUARD_PASSWORD=your-password",
        "ghcr.io/samik081/mcp-adguard-home"
      ]
    }
  }
}

Remote MCP (connect to a running Docker container or HTTP server):
