adguard-mcp

MCP server exposing AdGuard Home read/write tools across one or more instances, plus AdGuardHome Sync status and control. 33 tools (14 reads / 13 safe-writes / 6 destructive).

Configuration

Set per-instance env vars. At least one instance is required.

ADGUARD_PRIMARY_URL=http://192.168.1.10
ADGUARD_PRIMARY_USERNAME=admin
ADGUARD_PRIMARY_PASSWORD=<password>

# Optional second instance:
ADGUARD_SECONDARY_URL=http://192.168.1.11
ADGUARD_SECONDARY_USERNAME=admin
ADGUARD_SECONDARY_PASSWORD=<password>

# Optional: which instance is default when a tool omits the `instance` arg:
ADGUARD_DEFAULT_INSTANCE=primary

Instance names are derived from the env-var middle segment (case-insensitive). Add ADGUARD_LIVINGROOM_URL/USERNAME/PASSWORD and the MCP picks it up on next start.

Every tool accepts optional instance: "<name>" to address a non-default box.

AdGuardHome Sync is optional and uses a separate env prefix so it does not collide with AdGuard Home instance names:

ADGUARDHOME_SYNC_URL=http://192.0.2.10:8080

# Optional, only when the Sync API is configured with Basic auth:
ADGUARDHOME_SYNC_USERNAME=sync
ADGUARDHOME_SYNC_PASSWORD=<password>

ADGUARD_SYNC_URL/USERNAME/PASSWORD is also accepted as an alias and is reserved for the Sync server, not an AdGuard Home instance named sync.

If neither Sync URL env var is set, Sync tools remain listed but return a clear config error when called.

Install

npm install -g @solomonneas/adguard-mcp

Or run via npx:

npx -y @solomonneas/adguard-mcp

Setup

Claude Desktop

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "adguard": {
      "command": "npx",
      "args": ["-y", "@solomonneas/adguard-mcp"],
      "env": {
        "ADGUARD_PRIMARY_URL": "http://192.168.1.10",
        "ADGUARD_PRIMARY_USERNAME": "admin",
        "ADGUARD_PRIMARY_PASSWORD": "your-password"
      }
    }
  }
}

Claude Code

claude mcp add adguard -s user -- npx -y @solomonneas/adguard-mcp

Then export env vars in your shell (~/.bashrc, ~/.zshrc) or pass --env flags.

OpenClaw

Plugin loads automatically once installed. Config goes in your ~/.openclaw/openclaw.json plugins.entries.adguard (or use the bundled openclaw.plugin.json):

{
  "plugins": {
    "entries": {
      "adguard": {
        "package": "@solomonneas/adguard-mcp",
        "activation": { "onStartup": true }
      }
    }
  }
}

Env vars from ~/.openclaw/workspace/.env are inherited by the plugin.

Hermes Agent

Add to ~/.config/hermes/agents.yaml:

mcp_servers:
  adguard:
    command: npx
    args: ["-y", "@solomonneas/adguard-mcp"]
    env:
      ADGUARD_PRIMARY_URL: http://192.168.1.10
      ADGUARD_PRIMARY_USERNAME: admin
      ADGUARD_PRIMARY_PASSWORD: your-password

Codex CLI

~/.codex/config.toml:

[mcp_servers.adguard]
command = "npx"
args = ["-y", "@solomonneas/adguard-mcp"]

[mcp_servers.adguard.env]
ADGUARD_PRIMARY_URL = "http://192.168.1.10"
ADGUARD_PRIMARY_USERNAME = "admin"
ADGUARD_PRIMARY_PASSWORD = "your-password"

Safety

  • Credentials only live in memory after env-load and are redacted from logs and error messages.

  • Tier 2 writes require an explicit confirm: true arg; the JSON schema documents this on every write tool.

  • Tier 3 destructive ops additionally require destructive: true. The model cannot disable protection or overwrite the rules block from a hallucinated tool call.
