Adguard Home Agent

CLI or API | MCP

---

Overview

Adguard Home Agent is a production-grade Agent and Model Context Protocol (MCP) server designed to interface directly with AdGuard Home MCP Server for Agentic AI!.

---

Key Features

• Consolidated Action-Routed MCP Tools: Minimizes token overhead and eliminates tool bloat in LLM contexts by grouping methods into optimized, togglable tool modules.
• Enterprise-Grade Security: Comprehensive support for Eunomia policies, OIDC token delegation, and granular execution context tracking.
• Integrated Graph Agent: Built-in Pydantic AI agent supporting the Agent Control Protocol (ACP) and standard Web interfaces (AG-UI).
• Native Telemetry & Tracing: Out-of-the-box OpenTelemetry exports and native Langfuse tracing.

---

CLI or API

This agent wraps the AdGuard Home MCP Server for Agentic AI! API. You can interact with it programmatically or via its integrated execution entrypoints.

Detailed instructions on how to use the underlying API wrappers, extended schema bindings, and developer SDK references are maintained in docs/index.md.

MCP

This server utilizes dynamic Action-Routed tools to optimize token overhead and maximize IDE compatibility.

MCP Configuration Examples

stdio Transport (Recommended for local IDEs e.g., Cursor, Claude Desktop)

Configure your IDE's mcp.json to launch the MCP server via uvx:

{
  "mcpServers": {
    "adguard-home-agent": {
      "command": "uvx",
      "args": [
        "--from",
        "adguard-home-agent",
        "adguard-home-agent"
      ],
      "env": {
        "ADGUARD_HOST": "your_adguard_host_here",
        "ADGUARD_API_KEY": "your_adguard_api_key_here",
        "ADGUARD_DEFAULT_ADMIN_USER": "your_adguard_default_admin_user_here",
        "ADGUARD_DEFAULT_ADMIN_PASS": "your_adguard_default_admin_pass_here",
        "LLM_ROUTER_MODEL": "your_llm_router_model_here",
        "LLM_AGENT_MODEL": "your_llm_agent_model_here",
        "GRAPH_ROUTER_TIMEOUT": "your_graph_router_timeout_here",
        "GRAPH_VERIFIER_TIMEOUT": "your_graph_verifier_timeout_here"
      }
    }
  }
}

Streamable-HTTP Transport (Recommended for production deployments)

Configure your client's mcp.json to launch the Streamable-HTTP server via uvx with explicit host and port definition:

{
  "mcpServers": {
    "adguard-home-agent": {
      "command": "uvx",
      "args": [
        "--from",
        "adguard-home-agent",
        "adguard-home-agent"
      ],
      "env": {
        "TRANSPORT": "streamable-http",
        "HOST": "0.0.0.0",
        "PORT": "8000",
        "ADGUARD_HOST": "your_adguard_host_here",
        "ADGUARD_API_KEY": "your_adguard_api_key_here",
        "ADGUARD_DEFAULT_ADMIN_USER": "your_adguard_default_admin_user_here",
        "ADGUARD_DEFAULT_ADMIN_PASS": "your_adguard_default_admin_pass_here",
        "LLM_ROUTER_MODEL": "your_llm_router_model_here",
        "LLM_AGENT_MODEL": "your_llm_agent_model_here",
        "GRAPH_ROUTER_TIMEOUT": "your_graph_router_timeout_here",
        "GRAPH_VERIFIER_TIMEOUT": "your_graph_verifier_timeout_here"
      }
    }
  }
}

Alternatively, connect to a pre-deployed remote or local Streamable-HTTP instance:

{
  "mcpServers": {
    "adguard-home-agent": {
      "url": "http://localhost:8000/adguard-home-agent/mcp"
    }
  }
}

Deploying the Streamable-HTTP server via Docker:

docker run -d \
  --name adguard-home-agent-mcp \
  -p 8000:8000 \
  -e TRANSPORT=streamable-http \
  -e PORT=8000 \
  -e ADGUARD_HOST="your_value" \
  -e ADGUARD_API_KEY="your_value" \
  -e ADGUARD_DEFAULT_ADMIN_USER="your_value" \
  -e ADGUARD_DEFAULT_ADMIN_PASS="your_value" \
  -e LLM_ROUTER_MODEL="your_value" \
  -e LLM_AGENT_MODEL="your_value" \
  -e GRAPH_ROUTER_TIMEOUT="your_value" \
  -e GRAPH_VERIFIER_TIMEOUT="your_value" \

Security & Governance

Built directly upon the enterprise-ready agent-utilities core, standard security parameters are fully supported:

Access Control & Policy Enforcement

• Eunomia Policies: Fine-grained, policy-driven tool authorization. Supports none, local embedded (mcp_policies.json), or centralized remote modes.
• OIDC Token Delegation: Compliant with RFC 8693 token exchange for flowing authenticating user credentials from Web UI / ACP → Agent → MCP.
• Scoped Credentials: Execution context runs restricted to the specific caller identity.

Runtime Security Grid

Feature	Functionality	Enablement
Tool Guard	Sensitivity inspection with human-in-the-loop validation	Enabled by default
Prompt Injection Defense	Input scanning, repetition monitoring, and recursive loop blocks	Enabled by default
Context Safety Guard	Stuck-loop detectors and contextual overflow preemptive alerts	Enabled by default

---

Installation

Install the Python package locally:

# Using uv (highly recommended)
uv pip install adguard-home-agent[all]

# Using standard pip
python -m pip install adguard-home-agent[all]
