# Cómo crear un agente de IA con Agno y el servidor MCP de ClickHouse

> Aprende a crear un agente de IA con Agno y el servidor MCP de ClickHouse

En esta guía aprenderás a crear un agente de IA con [Agno](https://github.com/agno-agi/agno) que puede interactuar con
el [SQL playground de ClickHouse](https://sql.clickhouse.com/) mediante el [servidor MCP de ClickHouse](https://github.com/ClickHouse/mcp-clickhouse).

<Info>
  **Notebook de ejemplo**

  Este ejemplo está disponible como notebook en el [repositorio de ejemplos](https://github.com/ClickHouse/examples/blob/main/ai/mcp/agno/agno.ipynb).
</Info>

  ## Requisitos previos
</div>

* Deberás tener Python instalado en tu sistema.
* Deberás tener `pip` instalado en tu sistema.
* Necesitarás una API key de Anthropic o una API key de otro proveedor de LLM.

Puedes ejecutar los siguientes pasos desde tu REPL de Python o mediante un script.

<Steps>
  <Step title="Instalar bibliotecas" id="install-libraries">
    Instala la biblioteca Agno con los siguientes comandos:

    ```python theme={null}
    pip install -q --upgrade pip
    pip install -q agno
    pip install -q ipywidgets
    ```
  </Step>

  <Step title="Configurar credenciales" id="setup-credentials">
    A continuación, deberás proporcionar tu API key de Anthropic:

    ```python theme={null}
    import os, getpass
    os.environ["ANTHROPIC_API_KEY"] = getpass.getpass("Enter Anthropic API Key:")
    ```

    ```response title="Response" theme={null}
    Enter Anthropic API Key: ········
    ```

    <Info>
      **Usar otro proveedor de LLM**

      Si no tienes una API key de Anthropic y quieres usar otro proveedor de LLM,
      puedes consultar las instrucciones para configurar tus credenciales en la [documentación de Agno](https://docs.agno.com/models/overview)
    </Info>

    A continuación, define las credenciales necesarias para conectarte al Playground de ClickHouse SQL:

    ```python theme={null}
    env = {
        "CLICKHOUSE_HOST": "sql-clickhouse.clickhouse.com",
        "CLICKHOUSE_PORT": "8443",
        "CLICKHOUSE_USER": "demo",
        "CLICKHOUSE_PASSWORD": "",
        "CLICKHOUSE_SECURE": "true"
    }
    ```
  </Step>

  <Step title="Inicializa el servidor MCP y el agente de Agno" id="initialize-mcp-and-agent">
    Ahora configura el ClickHouse MCP server para que apunte al ClickHouse SQL playground
    y luego inicializa nuestro agente de Agno y hazle una pregunta:

    ```python theme={null}
    from agno.agent import Agent
    from agno.tools.mcp import MCPTools
    from agno.models.anthropic import Claude
    ```

    ```python theme={null}
    async with MCPTools(command="uv run --with mcp-clickhouse --python 3.13 mcp-clickhouse", env=env, timeout_seconds=60) as mcp_tools:
        agent = Agent(
            model=Claude(id="claude-3-5-sonnet-20240620"),
            markdown=True,
            tools = [mcp_tools]
        )
    await agent.aprint_response("What's the most starred project in 2025?", stream=True)
    ```

    ```response title="Response" theme={null}

    ┃ To answer your question about the most starred project in 2025, I'll need to query the ClickHouse database.     ┃
    ┃ However, before I can do that, I need to gather some information and make sure we're looking at the right data. ┃
    ┃ Let me check the available databases and tables first.Thank you for providing the list of databases. I can see  ┃
    ┃ that there's a "github" database, which is likely to contain the information we're looking for. Let's check the ┃
    ┃ tables in this database.Now that we have information about the tables in the github database, we can query the  ┃
    ┃ relevant data to answer your question about the most starred project in 2025. We'll use the repo_events_per_day ┃
    ┃ table, which contains daily event counts for each repository, including star events (WatchEvents).              ┃
    ┃                                                                                                                 ┃

    ┃ question about the most starred project in 2025:                                                                ┃

    ┃ This project, DeepSeek-R1, appears to be an AI-related repository from the DeepSeek AI organization. It gained  ┃
    ┃ significant attention and popularity among the GitHub community in 2025, earning the highest number of stars    ┃
    ┃ for any project during that year.                                                                               ┃

    ┃ It's worth noting that this data is based on the GitHub events recorded in the database, and it represents the  ┃
    ┃ stars (WatchEvents) accumulated specifically during the year 2025. The total number of stars for this project   ┃
    ┃ might be higher if we consider its entire lifespan.                                                             ┃
