Ready to transform your SEO workflow from tedious to effortless?

What is this SEO agent all about?

The SEO agent is all about a practical blueprint for building sophisticated AI agents that leverage external data sources through standardized protocols.

At its core, it demonstrates how to create an SEO research agent that connects to DataForSEO's comprehensive database using MCP.

This implementation transforms complex API interactions into natural language conversations. Instead of wrestling with REST endpoints and JSON responses, users can simply ask questions.

Google Agent Development Kit (ADK)

Google ADK provides a robust framework for building intelligent agents powered by large language models.

The framework abstracts away the complexity of managing model interactions, tool integration, and conversation flows.

ADK agents can reason about user requests, decide which tools to use, and present results in human-friendly formats. It supports both simple function calls and complex multi-step reasoning processes.

The LlmAgent class serves as the foundation for all agent implementations in ADK. It handles the "thinking" aspect of your application, leveraging Google's powerful language models for natural language understanding and response generation.

Unlike traditional deterministic workflows, LlmAgent behavior adapts dynamically based on context and user input. This flexibility enables agents to handle unexpected questions and novel scenarios gracefully.

Model Context Protocol (MCP)

The Model Context Protocol represents a breakthrough in AI tool integration standards.

MCP defines how large language models communicate with external applications, data sources, and services.

Think of it as a universal translator that allows AI agents to interact with any MCP-compliant service seamlessly. This standardization eliminates the need for custom integration code for each external service.

MCP follows a client-server architecture where your ADK agent acts as the client. The protocol supports three main types of interactions: accessing resources (data), using prompts (templates), and calling tools (functions).

This comprehensive approach ensures that agents can leverage the full capabilities of external services. The stateful nature of MCP connections enables more sophisticated interactions compared to traditional REST APIs.

The SEO ADK Agent

Setting Up Your Development Environment

python provides the foundation for the entire system, offering improved performance and security features.

node.js and npm are essential for running MCP servers distributed as node.js packages.

git enables version control and easy project cloning from repositories.

Project Structure and Dependencies

The project uses minimal dependencies, relying primarily on the Google ADK framework and standard Python libraries.

[project]
name = "googleadk-agent-mcp"
version = "0.1.0"
description = "Google ADK"
readme = "README.md"
requires-python = ">=3.12"
dependencies = [
    "google-adk>=1.5.0",
]

The core agent implementation resides in the module seo_agent/agent.py, while configuration details are handled through environment variables. See the project structure below.

❯ tree
.
├── main.py
├── pyproject.toml
├── README.md
├── seo_agent
│   ├── __init__.py
│   └── agent.py
└── uv.lock

Setting Up the Environment

uv package manager provides faster dependency resolution and installation compared to traditional pip.

# Clone the repository
git clone git@github.com:juancolamendy/mcp-tutorials.git
cd googleadk-agent-mcp

# Install dependencies
uv sync

Environment Configuration

The agent requires specific environment variables for authentication.

Creating a .env file in the project root provides a secure way to manage these sensitive credentials.

GOOGLE_GENAI_USE_VERTEXAI=FALSE
GOOGLE_API_KEY=[YOUR_GOOGLE_API_KEY]
DATAFORSEO_USERNAME=[YOUR_DATAFORSEO_USERNAME]
DATAFORSEO_PASSWORD=[YOUR_DATAFORSEO_PASSWORD]

The GOOGLE_GENAI_USE_VERTEXAI flag determines whether to use Google's Vertex AI or the standard Generative AI service.

Setting this to FALSE typically provides easier setup for development environments.

The API key authenticates your application with Google's AI services, enabling model access. DataForSEO credentials allow the MCP server to access comprehensive SEO research data.

Agent Configuration and Instructions

The heart of the agent lies in the agent's instruction set, which defines its personality, capabilities, and behavioral constraints.

These instructions serve as the agent's "DNA," determining how it interprets user requests and formulates responses.

instructions = """
# ROLE:
You are an expert SEO researcher and strategist.

# GOAL:
Answer user questions about SEO research and strategy.
Follow the instructions provided to you.

# INSTRUCTIONS:
- use DataForSEO mcp tool to get the keywords releated data such as search volume, cpc, competition, etc.
- if the user asks about something that is not related to SEO, say that you don't know
"""

The instruction structure follows a clear hierarchical pattern: role definition, goal specification, and detailed behavioral guidelines.

This approach ensures the agent maintains focus on SEO-related tasks while providing helpful responses.

The constraint to acknowledge knowledge limitations demonstrates responsible AI design principles. Such boundaries prevent the agent from providing potentially misleading information outside its domain expertise.

MCP Toolset Integration

The MCPToolset class serves as the bridge between ADK agents and external MCP servers.

This integration layer handles connection management, tool discovery, and request proxying automatically.

The agent uses StdioServerParameters to establish communication with the DataForSEO MCP server through standard input/output streams.

You can read more about DataForSEO MCP at https://dataforseo.com/help-center/setting-up-the-official-dataforseo-mcp-server-simple-guide

This approach enables secure, efficient communication while maintaining process isolation.

seo_mcp_toolset = MCPToolset(
    connection_params=StdioServerParameters(
        command="npx",
        args=[
            "-y",
            "dataforseo-mcp-server",
        ],
        env={
            "DATAFORSEO_USERNAME": os.getenv("DATAFORSEO_USERNAME"),
            "DATAFORSEO_PASSWORD": os.getenv("DATAFORSEO_PASSWORD")
        },
    ),
)

The configuration demonstrates several important patterns for MCP integration.

Environment variables handle sensitive credentials securely, preventing hardcoded secrets in source code.

The -y flag for npx ensures automatic package installation, reducing setup friction for users. The environment parameter passes authentication details to the MCP server process seamlessly.

Agent Initialization and Model Selection

The agent uses Google's Gemini 2.0 Flash model, which provides an optimal balance of performance, cost, and capability for SEO research tasks.

The model selection significantly impacts agent behavior, response quality, and operational costs.

ADK's model abstraction allows for easy switching between different language models as requirements evolve.

root_agent = LlmAgent(
    name="seo_agent",
    model="gemini-2.0-flash",
    description=(
        "Agent to answer questions about SEO research and strategy."
    ),
    instruction=instructions,
    tools=[seo_mcp_toolset],
)

The agent name serves as a unique identifier, essential for multi-agent systems and debugging.

The description helps other agents understand this agent's capabilities when routing requests.

The tools parameter connects the agent to the DataForSEO capabilities through the MCP toolset.

This modular design enables easy addition of new tools and capabilities as needed.

And the whole code is below. You can pull it from github at: https://github.com/juancolamendy/mcp-tutorials/tree/main/googleadk_agent_mcp

Running the Agent

We can run the agent using the web interface which offers the most user-friendly experience for testing and demonstration purposes.

Command-line interaction provides more direct control and easier debugging capabilities.

# Start the web interface
uv run adk web

# Or run directly from command line
uv run adk run seo_agent

Example Queries and Expected Responses

The agent excels at handling complex SEO research queries that would typically require multiple API calls and data processing steps.

Users can request comprehensive keyword analysis using natural language queries.

The agent interprets these requests, calls the appropriate DataForSEO tools, and presents results in human-readable formats.

Provide a keyword research study for the metrics: [Monthly Search Volume, Competition Level, 
Cost Per Click, Keyword Difficulty, Search Intent], region: [United States],
